Message-ID: <201710010759.v917xRR9018221@mail46c28.carrierzone.com>

Discussing plans for next year with my wife we came to the decision 
that the 2.4m ku-band dish probably needs to go by next 
May/June.  I've stored it for 20-years and having put up the 4.9m 
dish this one probably will never get used so it is FREE (you pick it 
up in Nikiski, Alaska).  Details are on:
http://www.kl7uw.com/fs.htm scroll to bottom of the page.

It weighs about 300-400 lbs.  This dish was a custom-made (1990's) 
shipboard VSAT terminal on 14-GHz and has digital encoders for 
az-el-pol with selsyn drive motors for all three axis.  I have the 
dish drive electronics boxes but not the sw that controlled it via 
internal computer.  I has WR-90 feed with rotating joints.  Original 
cost $98K.  I got it for $100 from my former employer.

If no takers (only reasonable for an Alaskan ham) the dish and frame 
with be hauled to the recycle center for scrap.  Dish can be hauled 
in back of a pickup but dish would extend 8-foot wide.  Probably need 
a loader or tow truck to lift it.

Exactly right. There's also the issue of finding monitors that will run on 12-14VDC, so that they can be powered from clean power supplies. :) ______________________________________________________________

I am surprised about the 6700 comment.

There is a Software fix for SmartSDR that addresses the pre-amps on the
6700.  I wonder if he had it applied.

Like Wes-N7WS writes, I have a SDR-IQ and use Spectravue.  I have the 
SDR-IQ in parallel with my K3 looking at 28-MHz IF output from my 
transverters 144 thru 1296.  I mainly use the "Combo" display for 
watching 100-KHz of activity on 1296-eme or use the "Continuum" 
display for measuring sun noise vs cold sky to check dish 
performance.  But understand Ian's need to watch 250-KHz for crowded 
EU VHF contests.

I'd like to make an endorsement (OT) for Ian's Triode Board which he 
sells for high-power triode amplifiers.  It made building my 2m-8877 
possible as all bias, current and HV monitoring and overcurrent 
protection are handled, including warm-up delay timing.  If you are 
building a high power triode amp this IS the needed component.  My 
Triode board has faithfully run 1500w key-down JT65 for several 
years.  Thanks Ian.

Of course if you are running sspa it does not apply.

I hope to have a 1200w 2m LDMOS 2m linear (W6PQL-kit) running by 
spring so my 8877 linear and HVPS will be available for sale at that 
time (probably OT for this list).  Due to shipping size/cost I may 
part out the HVPS and 200-lb. HV transformer FS here in Alaska.

Hi Dave

I connect the SDRplay through a 3dB splitter at the 28MHz RX output of
the transverter. A hybrid splitter is used to maximize the isolation
between the SDR and the K3's receiver.

This method is used in preference to the internal 8.2MHz IF output of
the K3 because the transverter output port can deliver a higher
signal/noise ratio to the input of the SDR, which improves its ability
to display extremely weak VHF/UHF signals.

Just saw an ad for Genie LED Bulbs.

Apparently some LED light bulbs make enough noise that they desense the 
garage door receiver.

These bulbs are specifically low-RFI.

I have no more information.  For all I know, they fix the garage door 
RFI by moving the noise to 14.300 MHz.

Lots of noise on both bands; storm noise and space noise combined.? QSB

Hope to hear you all again next week.

Jack,
This should get you started. This is from the KSYN3A FAQ dated February 13,
2015.

8. What is required to use the 600-meter band?    a. This band is available
in some countries, often on an experimental basis. Specific restrictions may
apply. A K3 fitted with a KSYN3A, as well as a KXV3 and KBPF3A, can receive
signals on this band, and can put out about 1 milliwatt of transmit power.
An external amplifier will be needed, connected to the XVTR OUT jack. At
present we don't have information on such amplifiers. You can also get on
this band using an upconversion transverter whose output is on a low HF band
(also not presently supplied by Elecraft). For a general introduction to the
600-meter band, see:
http://en.wikipedia.org/wiki/600-meter_amateur_radio_band   
   
9. Can a transverter I.F. of "0" be defined as an alternative to setting
CONFIG:KXV3 to TEST?    a. Not at this time, though we hope to add this
capability. Those who frequently alternate between TEST and NOR modes can
assign the KXV3 menu entry to a programmable 
function switch, or write a switch macro to change this menu setting as well
as set up the VFO, preamp, etc., for this band.

*** Here is information provided by Wayne in an e-mail to the reflector on
9/16/2017:

Here's some info to get you started on 630 meters with the K3S or K3. For
receive purposes, either transceiver is fully self-contained. For transmit,
you'll need an external amp of some kind.

RECEIVE

The K3S, or a modified K3, will receive on this band via the XVTR IN jack
(or RX ANT IN). You'll need:

  - A KXV3 transverter interface module (standard with the K3S but optional
for the K3)

  - A KBPF3A filter module, or a KBPF3 with a small mod (see KBPF3MDKT). The
KBPF3A mod kit also comes with a capacitor to be installed on the K3's RF
board to suppress LF noise.

RX performance is quite good on 630 meters. 

Note: The XVTR IN and RX ANT IN jacks work on 630 meters (472 kHz) because
both are post-TR switch. The TR switch has high-pass filtering that rolls
off starting around 1 MHz, so you can't use ANT 1 or ANT 2.

TRANSMIT

You can get a transmit signal out on 630 meters using the XVTR OUT jack
(same requirements as above). Our initial tests shows about 0.5 milliwatts.
In this case you'd use XVTR IN for receive, not RX ANT IN. 

You'll then need an external amplifier. It could be keyed using the rig's
KEY OUT jack. This signal could also be used to control a T/R switch if you
needed to use the same antenna for both transmit and receive. If you use two
different antennas, you'll still have to cut the RX antenna off during TX,
most likely.

Firmware configuration:

To use XVTR IN and OUT on this band, set up the radio for 160 meters, then
set the CONFIG:KXV3 menu entry to TEST. This is necessary because 160 meter
isn't available as a transverter IF selection (yet).

73,
Wayne

Jack,

You will need the new synthesizer - two if you have the KRX3.
You will also need the KBPF3A.  If you already have a KBPF3, there is an 
upgrade kit that you can install - the KBPF3MDKT (see K3 Parts and Mod 
Kits).
You will also need the KXV3 (or KXV3A or KXV3B) option in your K3 
because the antenna must connect to the RX ANT IN or XVTR IN.  Transmit 
is on the KXV3 XVTR OUT jack - you will need an amplifier because the 
output is low level (none sold by Elecraft).

Don W3FPR

Don's procedure in his doc works great.   But there is a gotcha that I
don't recall being covered.

The ALC meter algorithim "beats" with certain tuning tones and when that
happens, it makes the ALC meter ramp up and down in a fast oscillation.

This has been discussed on this list relatively recently.  I ran into it
last weekend.

The workaround is easy -- move the Tx frequency (shift click in the
waterfall) elsewhere until the ALC reading becomes stable, i.e. only the
last bar is flickering.  Then follow Don's advice.

How ironic. My two Genie garage door openers sit there and generate a huge
amount of buzz-saw hash on HF as long as they have power. I have to
essentially unplug them to use the radio, and my horizontal loop is 100
feet away from them.

Hello,

Because most of my operation has been remote lately, I am selling one of my
two K3 transceivers. Both are in superb condition.  I only need one and
will be keeping the one that does not sell.

If interested, please contact me off list and I will send you the specs for
both.  The serial numbers are 5530 and 6066.  I am the original purchaser
of both rigs and both are in superb working order.

Perhaps this is a software problem, but I thought I'd start here.  Using K3
(s/n 68xx), SignalLink USB and WSJT-X.  Everything works fine on FT8 on all
bands but 17 & 30.  I can decode on those bands, but there is no xmit.  The
rig keys OK and goes into xmit but there is no output.  Radio performs
normally on CW and SSB on these bands.  I use the same TX Data mode on all
bands.  Thought maybe there might be a hidden menu item that I might have
screwed up.

Anyway thanks for any help.

Subject: [Elecraft] Upgrading K3 s/n 11xx to operate on the 472KHz
Message-ID: <201710022239.v92MdLEG010317@mail42c28.carrierzone.com>

I used my K3 on 495-502 KHz as an experimental station.  I got 1mw 
output at the XVT Tx output jack running the TEST mode.

For amplifier, I bought a surplus Southern Avionics NDB (aircraft Non 
Directional Beacon) transmitter.  It is a xtal controlled oscillator 
amplified to 100w into 50-ohm load.  25w and 50w NDB's were also 
made.  Check surplus electronic sales for them.  I suspect the supply 
will be small and quickly disappear once discovered by new 630m hams.

Using with the K3, I removed the oscillator ckts and used a 0.1 mfd 
disc ceramic cap to couple from coax to the bandpass filter (single 
slug-tuned coil which feeds a 2N2222 pre-driver (about 10mw 
output).  I disconnected the internal antenna loading coil and 
switched the multi-tapped output coupling coil to 50-ohms.

You will need to build a base loading coil for using a very-short 
vertical antenna (if you have one for 160m, just substitute the loading coil).

630m is brand new ham radio country so prepared to design, modify, 
and build some of your equipment and antennas.  Or wait a year or so 
as small mfr's will likely show up or start up providing gear.

I should have approval by Oct. 15 to start on 472-479 KHz.  I plan to 
use CW/psk31/FT8 as ham modes and run an APRS beacon on 471-KHz as 
WD2XSH/45 under the old ARRL Experimental License.  Many of us are 
looking to run beacons around 471-KHz just outside the new 630m Ham 
Band (only legal if you hold an experimental license).

How much SSB do you do on 30 meters?

I'd start by re-checking the Data/submode on the two bands.

Interesting question.  But I doubt W0RSR operates SSB on 30 :)  Or I hope he does not.  A better question would be what software are you running, and on which operating system, e.g., Windows, MacOS or linux?  Since WSJT-X is the only software package I know that supports FT-8 I doubt it is a radio issue. Or at least I don?t have any issues with FT-8 on any band using WSJT-X RC2.

Have the preferences MacOS/ Windows configuration been updated since the WSJT-X upgrade to RC2?  WSJT-X is slightly quirky as I had an issue with pervious versions with JT9.  On some bands it worked, and on some it didn?t.  A reset of preferences, i.e., a complete reset of preferences brought it back.

I?m on MacOS so your mileage may vary.

Message-ID: <CAJmEykiKha7PmP-hP4J2ONs0wq1eeCcUdFm3HDp12XJuKMj-1Q@mail.gmail.com>

The SWR bridge on my K2/KPA100 had been working perfectly for years, but I
apparently blew something while making comparison measurements with a
friend's K2 I was trying to fix. Now the K2 panel LCD SWR indicator reads
around 5:1 for a near-perfect dummy load.  Adjusting C1 makes almost no
difference.  I can force the SWR to read 1:1 by setting R26 toward one end
of its travel and R27 toward the opposite end of its travel (instead of
both at midpoint), but then every load reads as 1:1 SWR.  Replacing D16 and
D17 didn't help (I tried it twice).  Except for the SWR reading, everything
seems OK.  Perhaps I should try replacing U5 and U6?  Other ideas?   Dick,

Dick,

Make certain you have the diodes D16 and D17 mounted the right way around.

Replace the coax jumper to the dummy load - measure your dummy load with 
your ohmmeter to be certain it is a good 50 ohm dummy load (yes, dummy 
loads can fail).

Then balance the wattmeter.  Easiest way is to power the K2 from only 
the coaxial 2.1mm power jack (no power to the KPA100) with power set to 
10 watts and adjust C1 for a voltage as close to zero as possible read 
at TP4 (should be in the low mV range).  If you cannot see a very low 
voltage at TP4. then measure U5 pin 3 and adjust C1 for the lowest voltage.
Next with power off preset R26 to 43k ohms read at U5 pin 5 and R27 to 
43k read at U5 pin 3.

You can do the initial tests of the wattmeter still in low power mode 
(no power to the KPA100).  Set for 10 watts and do a TUNE - do not stay 
in TUNE for more than 30 seconds at a time, allow a 1 minute cooling off 
period between each TUNE.
Check the DC voltage at U5 pin 3.  It should be close to zero.  The 
voltage at U5 pin 6 should also be close to zero.  Also check the 
voltage at U1 pin 3 which should also be near zero, and the K2 display 
should show an SWR of 1.

Connect an external wattmeter between the dummy load and the KPA100 - 
make certain you use known good coax jumpers.

Now do a TUNE and set R26 so the display power is the same as your 
external wattmeter.

Next, with the same TUNE conditions, measure the DC voltage at U5 pin 5.
You should see the same DC voltage at U5 pin 7, and at U1 pin 2.

Those two voltages at U1 will determine the SWR calculated by the KPA100 
firmware and passed along to the base K2 MCU.

If all is well on the DC voltages to this point and the K2 still shows 
an SWR greater than 1.0 or 1.1, you have a KPA100 firmware problem.

If the firmware is showing the correct SWR, then set R26 so the K2 
display shows the same power as on your external wattmeter.  You will 
want to refine that power (R26) adjustment at 100 watts later but the 10 
watt level will be sufficient for the initial setting.

If you are not able to set the power display without deviating 
substantially from the 43k initial setting, then check the DC voltages 
during a TUNE at U6.  The DC voltage at U6 pin 3 should be the same as 
that measured at U5 pin 7, and the DC voltage at U6 pin 6 should be 
about twice that at pin 3.

Take it one step at a time and in the order that I indicated.  If you 
skip around, you will become confused because one thing depends on the 
step before it.

If all those conditions are correct, the KPA100 wattmeter is working 
correctly.  Power the KPA100 and try it at 100 watts (hold TUNE/DISPLAY 
together).  Quickly adjust R26 to display the actual power.  If you have 
to move R26 very far, then you have a problem with the scaling. 
Transistors Q10 and Q11 may not be working properly.

Don,

I set both R26 and R27 to 43K Ohms, applied power directly to the base unit
(no power to KPA100), and set power know to call for 10 W.  In TUNE mode
the SWR reads about 9.9:1 regardless of C1 setting.  I think the C1 setting
has no effect.  I measure the power out at about 15 W, and the K2 says it's
putting out about 5 W.  Voltage at U5 Pin 3 is about -1.040 V.

The actual power out stays high when I adjust the power knob (exiting TUNE
mode between attempts), but it starts falling off rapidly when I call for
less than 1 W.  At calling for 0.1 W (full CCW on the power knob), U5 Pin 3
is about 70 mV, SWR reads 4:1, the K2 display says 0.1W output. (I'd guess
real output at that point is around 1.0 W--hard to interpolate that low on
my Heathkit HM-2140 power/SWR meter.

I've checked and tried a couple different dummy loads and jumper sets, and
I confirmed D16 and D17 are mounted in the right direction.

Dick, K0KK

Dick,

Is that voltage at U5 pin 3 actually negative?? If so diode D17 is 
backwards - the voltage should be positive in all cases.? Yes, C1 will 
not adjust if the D17 polatity is wrong.
You can refer to the parts placement diagram at the back of the KPA100 
manual if you cannot see the silkscreen clearly.

After putting D17 in correctly, recheck the 43k initial setting of R27 
and go from there.

pretty low.

I don't get anything with the mic connected to the rear mic jack. Config

K3s is new so I may be missing some menu item.

Hi,

I have a K3s with FW 5.60.

On all bands except 30 meters, when I place the rig into the DATA mode, I
see the green RX window on my P3 showing to the right of the center (dial)
frequency and matching my selected filter width.  This is what I'd expect
as DATA should be sending the equal of USB.  However, on the 30 meter band
only, the green RX windows is half above and half below the center (dial)
frequency.  It's acting like the mode is AM.  Also I can't shift the filter
below 1.1 KHz (at least for a 2.8 KHz filter).

This must be some "Per Band" feature that I am not understanding.

Any idea as to how I can get 30 meters to work like the rest of the bands?

Yes, the voltage is negative on U5 Pin 3, but D17 is not installed
backward--i.e., the cathode band is on the side away from the coax
connector, as shown in the manual.  I tried reversing the diodes (cathode
band on the side of the the coax connector), and Pin 3 voltage does drop to
millivolt positive range, and the SWR shows 1:1, but the power output
doesn't change regardless of the "power" knob setting.  I verified that the
diodes are banded correctly with a semiconductor tester.    Dick, K0KK

Are you in the right sub-mode? (hold the "DATA MD" (AFX) button, then
make sure you're in "DATA A")

Dick,

That is mystifying.?? With the diode "backwards", you get a positive 
voltage at U5 pin 3 - that should be the correct orientation for D17.

For the power indication, check the polarity of the voltage at U5 pin 5 
- if that is negative, then D16 is also backwards.

You may have a situation where T4 is not wound with the correct sense, 
although the orientation of the diodes should still produce a positive 
voltage at U5.
Something is strange here.

Message-ID: <bc216780-ce34-3997-bf70-a36e5852a733@stny.rr.com>

I built a K2 that included the voice option and KAT100 amplifier back in 
2008.? For the last six years it has sat, seldom turned on.? Now that my 
son is off to college I have had an opportunity to sit down with it and 
attempt to make some contacts.

I also constructed an inverted dipole back then and it runs through an 
Elecraft Balun to the transceiver. The Balun has the 1:1 and 1:4 options.

Upon powering up, both the transceiver and KAT100 come on. However, when 
I press and hold Tune, whether on low power (less than 10 watts) or on 
high power, I always see 2.04r on the left of the screen.? On the right 
is see what appears to be an SWR of 1.1:1 when? on low power.?? On high 
power it varies.? The LED's on the front of the KAT100 for SWR only on 
occasion light up during tune.

My transmission line runs through an MFJ 864 power/SWR meter, but the 
meter needle barely moves regardless of the amount of power I apply.

I cleaned up connections outdoors on the antenna and am ready to start a 
discussion with anyone willing to assist.? I am even willing to sit at 
the radio and talk on the phone so it might move along before snow flys 
here in central New York State!? haha.

Since the rig worked prior to the downtime, this might be a matter of 
only assisting me in memory recall on how to use the rig.? It could also 
be something that has occurred due to sitting for a long time.

If you can assist contact me via email or ask me for my phone number.

Thanks for listening,

Best,

1258 is also secured with velcro, the wifi dongle is secured to the top 
of the 1258, and the A/B data switch is stuck to the top of the P3.? I 
also got some 1 ft [0.3 m] cables to hook it all up.? The Winkey and

The SM58 is a poor choice for ham radio because of its bass boost. It 
should work if it's wired correctly, but it will be too bassy.

No preamp is needed. Follow manual for menu setting for Mic Gain to High.

My guess is that the cable is not wired to mate with the K3. Study the 
pin-out in the K3S manual. From the balanced mic, connect one of the 
signal wires to Mic In, the other signal wire to Mic Return, and the 
cable shield to the chassis.

I have had my P3 on top of the K3 for years. I have the same 
problem as Fred with things sliding off. I fixed it by building 
an aluminum bar across the back of the K3 that catches the feed 
on the P3. Loosening one screw will pop it off the K3 when I 
need to get inside.

Just got my KX3 package today, and assembly was a few hours without much 
trouble. Only thing that was somewhat unclear was getting the thermal 
material between the main case and the metal heat sink. If I took the 
clear plastic part off first, it wouldn't fit on the heat sink as the 
directions showed. Then it dawned on me to stick it on the back of the 
main case, where it was easy to pull the white part off, and all is 
well.? It worked when fired up and listening around 40 meter CW, so now 
after dinner back to the shack to learn the details!

Thanks to all at Elecraft!

Don,

I found the problem:  the short wire that connects the ungrounded side of
C1 to the SO259 jack had a poor solder connection.

I figured that since C1 wouldn't tune, there had to be a problem in that
bridge circuit prior to U5.   I started tracing each component's
connections with my Ohmmeter, and I finally discovered that the ungrounded
solder pad for C1 didn't connect.

Thanks for your help, Don.  You're a terrific resource and your
extraordinary efforts and patience in helping bewildered folks like me are
really appreciated.

Dick,

With that corrected, do you have some semblance of power control?
You should, but there are other pieces of the KPA100 wattmeter sending 
the VRFDET signal back to the base K2 MCU that could be producing a 
problem with the power output.

Paul,

The 2.04r is the MCU version, and it will be displayed if a button is 
held depressed when the K2 is powered on.  The right side of the display 
is the KIOC version and in your case should be 1.09.

So look for a button that is stuck on.  If you cannot see one, remove 
the metalwork from the front panel and try again.

With that button (whichever it may be) in an activated position it is 
unlikely that you can do anything with the K2.  Find that problem first 
before drawing any more conclusions.

Yes, smooth, complete control on power level from 1 W to 100 W, and the K2
power display and SWR track closely with my external meter.  I think
everything is working perfectly.

Subject: [Elecraft] Elecraft Frequency Memory Editor and mysterious power on
Message-ID: <003e01d33cc6$61399070$23acb150$@yahoo.com>

Hi everyone,

 

Two questions:

 

1.  I've got a brand new KX3, and I'm having a bit of trouble with the "Read
All from Xcvr" option in the Elecraft Frequency Memory Editor hanging up.
With a good connection from my Win 10 laptop via USB to my KX3, here's where
it hangs:

 

Context.State: ReadMemory2State

Reading memory 00

ReadMemory2State send "ER0C0040B4;"

Calling ReadMemory2State.OnDataReceived after 184 msec with Response
"ER0C0040FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF4;"

 

I tried it with a completely empty memory, and then I also loaded a few
memory locations (1 and 2, but not 0).  I got the same error both times.
The loading of frequencies seems to work fine, but the reading is where I'm
having problems.  Additionally, I checked this with my KX2 and got the exact
same error.  Is it possibly because memory location 0 doesn't have anything
in it?  If I read just, say, memory location 2, it works fine.

 

Anyone else seen the same thing?

 

2.  The unit randomly powered on the first night I had it assembled and then
again today while I was at work (twice in a 48 hour period).  So basically I
woke up the first morning and the radio was on.  It wasn't connected to
anything (no USB, no external power).  Last night I went to sleep with it
off, connected to my laptop via USB, and plugged into a power supply.  In
the morning it was still off, but I came home at lunch to find it turned on.


 

At first I thought it might be the clock/alarm, although I've never turned
the alarm on.  The first night, I had the clock set to local time, so my
hypothesis was that it came on at midnight, the default time of the alarm.
Last night I set it to Zulu time, which would explain why it came on during
the morning (0900 my time is 0000Z) since I'm in Japan.  However, I don't
know the exact times it turned on.  To test my theory, I left the alarm
turned off, but reset the time to 2358.  I waited two minutes but the radio
didn't power on, so my hypothesis might not be right.  I thought for a
minute that some random command from the laptop could have woken up the
radio, but it wasn't connected to anything the first night.  Anyone else see
something like this?

Hello Forum.
I have two PC's "A" & "B" running on WIN 10.

I now have two Transceivers:

An Icom 7800 connected to PC "A" via a 232 port/USB serial
converter cable.
This enables my logging Program Logic 9 installed on PC "A" to read the frequency, mode, etc from the 7800.
LOgic 9's database is on PC "A".

I have an Elecraft K3s connect to PC "B" via their USB ports, and operate my Data modes (FlDigi)
Easypal, CW, Olivia, RTTY, ect, using PC "B".
However I have to*manually*  enter all the QSO's worked on the K3s into LOgic 9 on PC "A".

Retaining the USB link between the K3s and PC(B), I would like to connect a link between
the K3s and LOgic9 on PC "A", to input the frequency, mode, etc from the K3s QSO's.

I only use one radio at any one time, switching the PTT and antenna connection's manually.

Ross

I do not know how Logic 9 program works.

I am using Logger32 program. It supports 2 radios.

In my case K3 is configured as Radio-1 and IC7300 as Radio-2.

QSO can be logged on the same Logbook whichever Radio I use.

Logger32 supports RTTY, PSK31 etc with implemented MMTTY/MMVARI

engine, however does not support new digital mode, FT8, JT65 etc.

I use JTDX program for these new mode. When QSO is logged in JTDX

then QSO data is transferred to Logger32 via TCP and Logger32 log this QSO.

Thanks for the replies and suggestions. I have confirmed that my audio levels are fine. This happens both on an antenna and a dummy load on 15 meters. The radio does always wind up transmitting at desired power and with good modulation within less than a minute. 

It is apparently just an odd quirk - I was just curious if anyone else had experienced this behavior, and wanted to tell the community about it.

When operating a KX3 with the internal ATU into a window line fed 
doublet through a BL2 balun, what is the preferred connection method:

1.? Placing the BL2 right at the KX3 output eliminating any coax.? This 
puts the window line right next to the metal KX3, everything else on the 
operating desk and the operator.


2.? Placing the BL2 five feet away and higher which puts the window line 
further away and connecting it to the KX3 through a short coax jumper.


3.? Placing the balun (weathered-proofed) right at the doublet's center 
and using coax for the whole run to the KX3.


Thanks and 73,

Stan,

Either of those options will work - however ---
I would suggest minimizing the coax.  The balun will not transform to a 
50 ohm load, so the coax can run at a high SWR which will give more loss 
than the window line.

Whether that minimum is zero or 5 feet will not make a significant 
difference, so use whatever is convenient for your station.

Don W3FPR

Don't know your software, but I would (using HRD) attempt to set the database up in server mode such that the HRD clients on either machine could add records...
Perhaps your logging software uses a database method that would allow the same approach.

Would not a bnc-to-banana plug adapter hooked to a doublet made from 100'
of zip cord be equally useful?   Is there even a reason to have a balun
in-circuit?   I've read the characteristic impedance of the zip cord (or
speaker wire, etc.) is about 75 ohms.  If you "unzipped" 67 feet or so and
put on a tie wrap (to avoid further unzipping), you'd have a quite
serviceable 40 meter dipole with an SWR of 1.5:1 or so.

This doesn't give you real-time logging, but fldigi can export your QSO 
info as an ADIF file which you should be able to import into Logic 9.? 
Better than manual ;)

Hi Jim
I believe this is where my problem is. The rear mic jack is wired as 
mono (ring is not connected to anything) so it is an unbalanced input. 
Connecting the mic audio(-) to the shield might work. Or an audio 
transformer could be used to convert from balanced to unbalanced ie., 
audio +/- to primary and one leg of secondary to tip and other to 
sleeve. Any thoughts on this?
Others must be using the rear jack. How are they doing it? Contacted 
Heil and they don't have an adapter.
I am mainly a cw op and just don't want the clutter of a mic (or the 
wiring) on the desk.

Rich,

It is a common misconception that the characteristic impedance of the 
feedline is what you will have to match.? That is only true for resonant 
antennas.? The feedpoint impedance of a dipole in free space is 72 ohms, 
but when mounted at practical heights above ground, the feedpoint 
impedance will drop.? For most HF antennas, 50 ohms is a better choice.

The other point is - yes, a balun is a good thing.? For parallel 
feedline, the balun should be at the junction of the coax and the 
parallel feedline to keep the antenna and feedline currents opposite and 
equal (the required condition for balanced), and to keep common mode 
current to a minimum.

For non-resonant antennas, the feedpoint impedance of the line at the 
transmitter can vary from very low to very high.? It all depends on the 
length of the feedline, the length of the radiator and the frequency.
In many cases, feeding an antenna with 450 ohm feedline, a 1:1 balun 
will work better than a 4:1 balun.
You must match the feedpoint impedance, and that is not the 
characteristic impedance of the line.

BTW, zip cord is quite lossy at RF, and should only be used in 
situations where nothing else is available.
Your example will work, but it is a one band antenna.? The main reason 
for using parallel feedline is to be able to use the antenna on multiple 
bands.

Don W3FPR

Thank you to everyone for the rapid responses.? Now I know my options.? 
As a long time feedpoint autocoupler user, this is a new approach for me 
and it's nice to get advice before cutting wire and cable up.

OK here's what worked: I used a pre-amp, that was on hand, that has a 
balanced XLR input and a TS jack output. The SM58 does need quite a bit 
of gain to work but sounds good using the tx monitor.
My SM58 has a switch so I set up to use VOX and the mic switch acts kind 
of like a PTT (only temp).
Amazon lists a Sescom AUD-XLR-RCA that seems to be nothing more than an 
audio transformer that converts balanced? to unbalanced. Might be just 
what is needed for higher output mics, such as some of the Heils.
Thanks for the help and I hope this helps others who want to use the 
rear jack on their K3s.

You can also tie an underwriters knot at the split point. 

Actually 67 feet twice makes a 135 foot dipole for 80 meters, not 40.

An XLR mic sound always be connected with Mic(+) to tip and Mic(-) to
the sleeve of the K3 rear panel mic jack.  A microphone (unless it is
a dual capsule M/S microphone) is always a mono device.  The K3 mic
inputs are *unbalanced* but any dynamic mic - including the "pro"
dynamic mics can be run unbalanced by connecting Mic(+) to tip and
Mic(-) to sleeve (mic return) and *leaving the shield floating*.

The Shure SM 58 is rated for -57.5 dBV/Pa that is only about 3 dB less
than most of the Heil dynamic mics and certainly within the capability
of the K3 with MENU:MIC SEL = rP.H and bias *OFF*.  No external preamp
required.

Apparently correct, Lynn.  I had my garage door serviced two weeks ago and the last thing the repairman did was pop open the frosted plastic bulb cover on the opener and say "just making sure you don't have LED bulbs in here.  They play havoc with the receiver on the openers).  He said most everyone in the garage door industry knows of that problem.  First I had heard of it.

Just saw an ad for Genie LED Bulbs.

Apparently some LED light bulbs make enough noise that they desense the garage door receiver.

These bulbs are specifically low-RFI.

I have no more information.  For all I know, they fix the garage door RFI by moving the noise to 14.300 MHz.

As mentioned before, the best option is ladderline attached directly to BL2
on KX3. 

I am using KX3 with BL1 set to 4:1 using random wires. I also use a direct
BNC-banana plug connection.
With the direct connection, match is obtained on many some but not all
bands, and often only after second pressing of the ATU button. On some
bands, touching KX3 causes SWR to rise. So impedances may be too complex for
KXAT3 to match, a match may include very high losses in KXAT3, and KX3 is
part of the antenna. 

With BL1, the match is always achieved, with antenna or without. No changing
of SWR with touching. So BL1 insulates KX3 from the antenna and 1) reduces
impedances to levels more easily matched by KXAT3 and 2) introduces own
losses.  I prefer BL1 because its better to heat the balun than the tuner. 

Ignacy, NO9E

I didn't post this because I hoped it'd help everyone with their Garage 
Door Openers.

I posted it because *if* the Genie Bulbs are low-RFI across the whole 
spectrum, that might be useful for other reasons.

	mobile/portable testing
Message-ID: <B021FDE2-FF1C-488E-81C2-8E2A03DF6B15@elecraft.com>

Hi all,

We?re looking for volunteers to test new firmware that allows extended control of the KX2 via an MH3 mic. This feature enables ?HF Pack Lite? operation, where the radio is inside a backpack with a whip attached. It?s also useful for mobile operation since it allows eyes-free radio control.

I?ve been using it on hikes, with excellent results. I use a small REI sling pack and a thin, flexible 44? whip to get as close to ?stealth? HF operation as possible.

Mic-based functions include:

- VFO up/down (default)
- CW message play
- CW handkey
- filter bandwidth
- AF gain
- VFO A/B swap
- mode
- band
- ATU tune
- power output
- battery voltage
- power OFF

The UP/DN buttons are used to access the various functions. Tapping PTT returns to VFO up/down, while a double-tap of PTT reports the operating frequency in kHz (using audio Morse tones).

If you?d like to give the new firmware a try, please email me directly.

73,
Wayne

Hi Stan:

Post ten.

There are two ways to approach this, just put something up, or measure
and optimize. When using the KX3 ATU, both methods will provide similar
results.

An 88 foot Doublet and feedline is modeled using EZNEC and SimSmith. The
results found here:
http://www.kn5l.net/Doublet88/

The Balun, both 1:1 and 4:1 is modeled with a perfect conventional
transformer block "A." The KX3 ATU is modeled with the L-C network block
"LC1." A five foot RG-58A/U between the Balun and KX3 is added.

For modeling, Wireman 551 is used and tuned for optimal results on 40
and 20. As shown, a 1:1 Balun results with the best match with SWR below
1.5:1 on both 40 and 20 at the KX3. With system loss below 1 dB.

For this antenna, other bands will have a better match with a 4:1 Balun,
with loses below 1.5 dB.

What is shown is that there is only about 0.5 dB difference between the
optimal and just put it up approach on 40 and above. Using a BL2 and
switching between 1:1 and 4:1 depending on the band.

A short antenna will have a very low impedance, causing the additional
feedline loss to increase significantly, Greater than 4.5 dB is for 80.

tuner: $1200
P3: $600
KPA500/KAT500 Combo:   $2000
Packing: in double-boxes, some Elecraft foam devices, bubble-wrap, peanuts.
_INSURED-only_ shipping: your arrangement, carrier or you to pick-up at my
FCC adr in ZIP 45212.
Total weight prolly 80lb boxed.
If interested, pls contact me _off list_ at five one three three five one
zero five seven nine, days/eves eastern US time, or N3HE at ARRL dot net.
I  hope to sell all as a station rather than separately.
However, this is not a time-sensitive situation, so I will hold any separate
offers. 
Don't be bashful.
I accept personal checks, with shipping after clearance.
Brgds,

No preamp required.? Set the Mike gain via the menu to high. Easy to 
wire the mike XLR to an unbalanced circuit.?? Pin #1 & #3 to ground and 
Pin #2 to MIC high.? See page 55? of the manual [MIC SEL] for details.

If you close talk the mike it will be bottom end heavy. Typically no 
closer than 4" will be OK.? Move in closer and the bottom end comes up, 
back away and the bottom end falls off. This is due to the proximity 
effect of they type dynamic mike.

Otherwise, they sound quite good/.

No transformer needed.? The gain settings on page 55 of the manual are 
sufficient for the SM 58.?? Just wire it as an unbalanced output.?? I 
use both the rear or front MIC inputs with no issues and a variety of 
different mikes.

 > Pin #1 & #3 to ground

Pins 1 and 3 should *never be tied together*.  If your transceiver has
a balanced input *or* a *separate* case/chassis connection, connect
pin 1 (shield/mic case) to the case/chassis connection (ideally to the
*shell* of a Foster mic jack that is bolted securely to the metal case
of the transceiver).

If your transceiver does not have a separate case/chassis connection
(the K3/K3S rear mic jack *does not*) leave pin 1 disconnected
(floating).

It doesn't matter if the input is balanced or unbalanced.  The shield
and mic return should *never* be connected together.  The shield is
connected to the case of the microphone *not* a signal (mic -) line
and connecting shield to mic - simply adds common mode noise and hum
to the low level mic (-57 dBV) signal.

If you want to connect a 6 foot radial to the mic input of your rig,
be my guest, but don't suggest it to others due to the potential for
hum, RFI and other garbage.   The only case where the shield and
mic - is tied together for unbalanced inputs is where the mic (-)
is *properly* returned to the chassis *at the input* and that is not
the case with the K3/K3S *or any other transceiver that I know of*.

I'm with Bob on this. While the K3 and K3S DOES have a Pin One Problem 
at the rear panel mic input (the cable shield goes to the chassis 
through a capacitor), floating the cable shield is not a good solution, 
and it should be tied to the connector sleeve.

When a rig? DOES provide chassis at the mic connector, the balanced mic 
lines should be wired to MIC+ and MIC-, and the cable shield should be 
tied to the chassis. In general, it's also OK to tie Pin 1 and Pin 3 
together AT THE RIG and connect them to the chassis.

73, Jim K9YC

That may work with the K3/K3S which have a relatively low impedance
between the mic return and chassis.  Tying the shield to mic return
is a complete disaster on older rigs (FT-1000D, FT-1000MP, most Kenwood,
etc.) where the mic return is the emitter of the mic preamp which has
an *unbypassed* resistor and/or RF choke to DC return/chassis.  That
[relatively] high RF impedance is like connecting an antenna directly
to the mic.

Subject: [Elecraft] CBLP3y Cable P3 to K3 connection
Message-ID: <1507307427526-0.post@n2.nabble.com>

I just acquired a P3, but was surprised to learn that I need a cable (CBLP3Y)
to enable the K3 VFO frequency to be displayed on the P3.  I located in my
toy box a couple cables of same description as the CBLP3Y, that being they
are terminated on one end by a RJ45 connector and a DB9 Male on the other. 
(I see in page 4 of the P3 owner's manual it calls this cable a Male-Female
DE-9, so that is confusing to me.  What is a DE-9 connector?).  My question
is to ask if my toy box cables will do the job, or is there something
specific to the CBLP3Y that  designates that as the only cable to use?

Someone please help me with this question.  Thanks,  Mike Pilgrim, K5MP

Mike,

DE-9 is the proper designation for what most call the DB-9 connector.
The proper "DB" designation is for the wide 25 pin size housing that was 
used for printers on the PC and on commercial modems.
When the IBM PC first came out, they used 9 pin connectors for the 
serial ports and many referred to them as DB-9 even though the proper 
designation for that size connector (no matter how many pins) is "DE".

Hi all,
First post after couple of years. Recently I?ve put my K3 back to my bench but I noticed that speaker is mute. It wasn?t before and after search for the issue, I found something regarding the protection of mono plugs connected at back of the radio, is that the case?
I connected only a DB37 for the microham and my headset was in. After I removed the headset, no sound.
If I connect my headset at front or back everything is fine, only the internal speaker is completely mute.
Any tip or idea?
Thanks in advance.

Message-ID: <CA+jbSKbxa=5NjwbxCL7PV0Kf6bM+d25ZTpMswey7jKCt47nP+g@mail.gmail.com>

When I switch to DATA mode, the receive bandwidth is only about 600 Hz even
though when I check with Data MD it shows the USB mode. I have the 2.8
filter selected and it shows on the display and using the K3 Utility
program. The audio also shows that there is only 600 Hz bandwidth. When I
switch back to USB mode, everything is working at 2.8 kHz. The highlighted
segment on the P3 showing bandwidth also confirms the two different
bandwidths, and WSJT-X also shows the decreased bandwidth in the DATA mode
and does not decode signals outside of that BW even if they are huge on the
fo P3.  I can't find anything about changing the RX bandwidth in DATA mode
in the manual...

Mike,
Now that Bill and Don have filled you in on the DB9 versus a DE9 issue, I'll
try to address your question about the CBLP3Y.
One of your cables alone will not do the job.
The CBLP3Y has two DE9s, one female the other male, and a RJ45 connector.
The male DE9 plugs into the connector on the P3 marked PC. The female
connector plugs into the connector on the P3 marked XCVR. The female DE9
connector has two cables connected to it. One cable goes to the male DE9,
the other cable goes to the RJ45. This means you will have to get a female
DE9 and do some soldering to make a CBLP3Y cable. I'm not sure there is a
wiring diagram to make your own. Support may be able to help with that. I
would vote to just purchase a CBLP3Y. I think it is $39.95 plus shipping. 

Mark, WB9CIF

Jim,

Yes, the filter width in DATA A mode defaults to a narrow bandwidth - 
even though you have the 2.8kHz filter, it still defaults to a narrow 
bandwidth like 400 or 600 Hz (I can't recall which).
That is an aid to those who choose to use the VFO dial to tune in a 
single data mode station.

SSB mode defaults to the 2.8kHz.

Not to worry, it is easy to change, just grab the WIDTH knob and turn it 
until you see a waterfall width to your liking.

Don W3FPR

Why did you turn the mic bias off?  Have you tried turning it on to see if
it gives you the sound you need?

Mic bias is used only with electret microphones.  Dynamic (moving coil)
microphones like the SM58 can be damaged by DC on the coil!  The bias
will certainly *further reduce* the output from the already low output
of the dynamic mic.

Hello,
I recently decided to upgrade my K2 to 60m and ordered the K60XV.
After building and installing the module and all the mods, I could hear 
signals on 60m, but very very weak. Using the XG3 showed a difference of 
8 S-points compared to all other bands. I tried to isolate the problem. 
I checked if the relay K1 would switch at all (removed U1 b4), ok. 
Checked if capacitance changes when turning C1/C2 - looks good. Then I 
installed the module without U1 installed - 60m not recognized any more. 
Seems that U1 is working, basically.
Then I fooled the K2 by installing U1 without pin 11 connected (by 
applying the IC-socket-sandwich trick). And ok, I could now tune 60m 
properly and to the same level as 40m.
So I got stuck now. Is U1 only "half-way" working, that is it does 
communicate on the AuxBus, but cannot drive K1? BTW, I also checked the 
transverter setup to see if relay K2 would be driven - and yes it clicks.
Any ideas welcome!
Thanks/73

Electret mics, and capacitor and carbon mics, neither of which are real 
common in hamdom these days, require a bias voltage in the 5-8 V range.? 
A K3 will provide that bias if it's turned on in the MIC menus.? Dynamic 
mics do not require nor like bias.? Without bias, an electret mic will 
produce no output. I believe the Shure mic in this thread is a dynamic mic.

Carbon mic elements from old black telephones would run nicely on 1.5 V 
from a D-size dry cell although the telephone generally ran on 48 V from 
the central office.

Gernot,

You either have a malfunctioning U1 or you have a bad relay at K1.
Since you were able to get K1 to operate and select 60 meters, I suspect 
U1 is the problem.  Request a replacement from Elecraft support.

Jim,

Why use XFIL at all?  The filter selection will follow the DSP filter 
bandwidth, switching in your filters as needed for the bandwidth 
selected by the DSP Width filter.

I never have found a use for the XFIL button on my K3, I do it all with 
the width control.

A perfect transformer is not a good model for two reasons:

1) The number of turns is too low to have a leakage inductance that is 
large enough to ignore, especially at lower frequencies; I think this is 
particularly true for the 4:1 configuration;

2) The general wisdom seems to be that you want a lossy core, so that 
the common mode current sees more of a real than imaginary impedance.

Looking through the archive, I didn?t find much info about what units people are using.  I did, however, notice several caveats about the latency of Bluetooth headphones, especially for CW.

It looks like there are now several BT headphones on the market that claim to have low latency, which may or may not be suitable for amateur radio use. Of course, an external BT transmitter would have to be plugged into the rig?s headphone jack.

One item that looks promising is the Avantree unit:

I'm no expert, but getting Bluetooth wireless phones and.or buds to work 
with sufficiently low latency is (based on my limited 
experience/research) dependent upon BOTH the BT version/capability 
(hardware AND software) in BOTH the phones/buds AND the BT 
receiver/transmitter in your device (laptop/desktop, et al).

I DO know that even my very nice and up to date Jaybird earbuds which 
are awesome for music, et al.? do not work with sufficiently low latency 
on my Dell E6540 Laptop with the Intel Wireless AC and Bluetooth card I 
am using.... I suspect it is a problem with the BT implementation used 
by the slightly long in the tooth Intel BT card...

Steve,

Is that with the KAF2 or the KDSP2 installed.

If the KAF2, you *must* change the date first - if it is correct, move 
it up and move it right back down.

That was intentional to keep the time from being accidentally changed in 
situations like Field where there are operators with 'curious fingers'.

If someone tries the Avantree (thanks, Al!) headset, please estimate or 
measure the latency for receive audio.? The spec sheet says nothing 
about an actual number, even though the banner adindicates Low Latency.? 
Without an actual number, that is pretty worthless.? Most consumer 
electronics specs are similar, so no big surprise.

A few years ago, I surveyed the field for BT headsets. Because most 
headsets are designed for high-quality audio, their latency can be 
crazy-high.? There were only a few manufacturers that targeted 
communications (think hands-free phoneor HTheadsets), but their products 
were crazy-expensive>? It's likely thatthe usecases were government / 
law enforcement.

Thanks,

Message-ID: <002401d33fc7$742219b0$5c664d10$@bigpond.com>

Hi All,

 

Apologies if this question posts twice - my attempt yesterday was
unsuccessful, so here goes again.

 

I've been running KX3 #2511 for several years on SSB with the MH3 mic and
with settings:  Mic gain 35 and compression 12.  It's worked flawlessly and
that combination of settings has

given me an ALC indication of 5 bars while speaking normally.  I'm running
the latest firmware.

 

Yesterday, I noted that I had no RF output on SSB and find that now I get no
ALC indication until the Mic gain is advanced to the maximum setting of 80.
Nothing else has changed in my

setup.  I've checked that MIC Bias is set to ON and the TX EQ settings have
not changed.  I've also checked and there is indeed a bias voltage on the
Mic socket.

 

I can still run digital modes in DATA mode A,  using an external soundcard
connected to the KX3 mic socket via an adapter cable and I easily get 4 bars
of ALC with the 5th flickering with a Mic gain of 35.  That hasn't changed.

 

I don't have another MH3 mic to check whether it's the microphone that's at
fault here, but that's my suspicion.

 

Any ideas where to look next? 

 

Many thanks, 

 

John

John,

Try backing down the MIC Gain setting to something low or mid-range.
If you get the mic voltage too high, the mic amplifier detects that and 
inserts attenuation that will shut the audio from the mic down.

So bottom line, start with a low MIC Gain setting and increase it until 
you see 5 to 7 bars on the ALC meter.

Dear Don & Group,

Thanks for your suggestions.  After some more exploration, I think the problem is the MH3 and here's why:

Backing down the mic gain didn't help and neither did a firmware reload.  I was suspicious of the MH3 being at fault, as the ALC / Mic gain adjustment remained perfectly consistent and reliable in data modes.
I then remembered I had a Yamaha CM500 headset lying in a drawer. I made an adapter (thanks Walter, K6WRU for your very helpful and clear webpage describing the adapter cable) I plugged it into the KX3 mic socket and lo and behold, the KX3 plays perfectly with it - the ALC shows 5-7 bars with a mic gain of 35-37 and I get the expected RF output, which is exactly how it used to be with the MH3.

I took the MH3 apart and mechanically it all looks sound, no loose wires or dry joints, and I checked that there is indeed a bias voltage on the mic + ( tip) wire at the microphone.  There's not much to go wrong in there, so I wonder if the electret element has died.

I'll order a replacement MH3, because even though the CM500 headset works well, I like using the handmic and I've always had good audio reports using it.  

Thanks everyone for your interest.

John,

If you can find an electret microphone element, you should be able to 
replace the mic element in your MH3 microphone.

OK, I did some digging and found marketing info from Avantree.  When they say ?no? latency, they mean ?some? - on the order of 40 msec when used with a transmitter that supports low-latency aptx codec mode.  This sounds reminiscent of a Monty Python sketch.

40 msec is about one dit at 30 wpm, which would probably throw me off. I?ve tried to listen to my own sending via various SDRs, and it?s agonizing.

Time to delve into analog solutions.

It's worth checking continuity through the cord as well. The wires in the
stretch cords do sometimes break. I used to service radios on large ships,
and broken stretch cord wires on the VHF bridge radios were common. The wire
usually looked fine - the insulation was intact - but the stranded wire
inside was broken.

Message-ID: <69E6A0DC-B7D6-41DA-B408-B0179D0D8BBF@law.du.edu>

Previous threads provided a great deal of info about arranging automobile electrical systems to power HF rigs.  But as I recall, it all focused on using the battery / alternator supply for the 13 VDC.  Though I wanted to go mobile and still do, for a number of reasons I could not configure my car to do it properly.  I am now thinking of buying a new SUV which has 117 VAC outlets in its rear cargo space.  That makes me wonder ? could I just use an ordinary 117 VAC to 13 VDC power supply, exactly as I do at home, just plug it in and ? staying within the car?s rated current draw ? operate without worrying about where the ground goes vis-?-vis the battery, what-all needs to be bonded with what-all-else, how everything needs to be mummified in ferrite, etc?  Or are the problems all the same even though different?  My objective is simple.  I want to be able to drive to a rare county, set up my buddipole in a parking lot, and use either a XX3/KXPA or a K2/100 to knock out some CW QSOs.

The 117V  AC may be produced by the vehicle using an inverter similar to those sold as separate devices. Years ago I was using one of those and found out that they would not allow the ground pin on the AC outlet to be connected to the 12V minus connection. If that is the case, you would have to be careful hooking things up.

Bias for mics does not "improve the sound" of a mic. Rather, bias makes 
electret mics work (you'll get no sound from them without bias), and can 
cause problems with dynamic mics. At the very least, bias can cause 
distortion with dynamic mics, and at worst might damage them. This is 
NOT a topic for experimentation. If you want to know more, I suggest 
that you study how mics work.

DC to AC inverters are notoriously noisy EMI/RFI-wise, even the so-called pure sine wave units. There's a good chance you'll have spurs right where you're trying to listen.
There *are* good units out there, but they're not cheap, and you'll still have to go through the exercise of proper cabling & bonding in order to realize a quality installation.

Although when using our travel trailer, I operate the radio from the 12V 
battery system,? I do have installed a 12 volt to 120 volt pure sine 
wave inverter.? This takes care of things such as computer, microwave, 
TV's and of course the all required "hair dryer" and etc.??? The unit is 
rated at 2KW.?? I've located it very near the battery using #4AWG copper 
for battery connections.??? I've made provisions to switch the entire 
trailer over between "external" power and "internal" power.??? We often 
camp where there is no electric service and may not be able to run the 
generator due to "quiet hours".? Overall the unit works well, seems to 
be about 85% efficient based on load,? and is reasonably RF noise 
free.?? As to 120 VAC provided in vehicles........I don't have any 
history or knowledge.

This is entirely unnecessary.  Use the cigarette lighter and MFJ power
conditioner. While you radio requires 20A peak, the power conditioner
reduces it to about 8 A average, which the cigarette lighter will do easily.

Overall, not a great plan.

Using an inverter, you will introduce RF noise, generate heat and poor 
regulation, unless you get a quality inverter (not cheap).? It's 
inefficient too and space wasteful.

If you use a power port (no longer called cigarette plugs), you will 
again introduce noise for your radio because they seldom have decent 
chassis bonding.? They are also low amperage capable and you can exceed 
that (check the owner manual or the fuse block), even if momentarily.? 
Often they are also part of the vehicle systems array, so you'll get 
noises and generate issues to/from the vehicle electronics, some of 
which are rather spendy to repair.

In the long run, it's best (and least expense) to simply run the (fused 
at both ends, both wires) power cable to a known, chassis bonded 
source.? Power is NOT a place to cheap out.? If you're QRP, it's simple, 
the wires aren't huge, check your IR^2 losses over the run (make sure 
there is no voltage drop AT the radio).

Hint:? Make sure EVERYTHING, power at the source, power at the radio, 
the radio itself AND the antenna are properly RF bonded (not DC) to the 
vehicle and you'll have less issues, which translates into more fun.

It doesn't sound like you are operating mobile at all if your antenna is a Buddipole in a parking lot.  Leave the vehicle turned off. No ignition noise or bonding to worry about. If that limits your operating time, carry another battery to power the rig (maybe a gel cell for safety) when you are parked. You can rig up a connection to the vehicle charging system to recharge the extra battery on the way to the next county. Your SUV either has a hitch or wiring for one where you can pick up a connection to the alternator. That's how a trailer battery is recharged.

For a 100 watt PEP HF radio or like VHF/UHF radio, the correct solution 
is a 3 wire system.? Positive - connected and fused at the battery and 
radio ends, Negative - connected and fused at the battery and radio 
ends, AND a 3rd wire connected to the firewall/frame {not battery 
negative} of the vehicle and connected to the ground terminal on the 
radio.? Usually there is a rubber boot or grommet in the firewall just 
to the left or right where the steering column passes through the 
firewall.? It is easy to push the needed wiring through this grommet.? 
Thus installation complete and no holes drilled, and one has a proper 
and safe electrical source for the radio.

Only if you have another counterpoise prepared other than the vehicle; 
otherwise it all needs to be bonded to the vehicle to raise the (already 
meager) antenna efficiency.? Short HF vehicular antennas only run in the 
lower single digit efficiencies, Buddipole or not.? You have to do all 
you can to make it at all.

Just because it loads and shows a good SWR doesn't mean it's working 
well, even a dummy load has a good match.? Mobile HF is an art.

I've used "good" ones (Samlex "pure sine wave" with FCC Part 15 Class B 
certification) and they ARE NOISY.? Using a lot of ferrite cores got 
their smallest one (100W) quiet enough on 40-6M to run the logging 
computer for a CW QSO party mobile operation.

Chassis bonding is NOT a solution to noise in a vehicle. Noise does not 
come in on the power wiring, it comes in on the ANTENNA. Indeed, there 
is no good reason to bond a radio to the chassis of a vehicle.

Many of the systems in a vehicle can generate noise, and some can be 
quite sensitive to RF. One of the on-board computers in my Toyota 
Sequoia (big SUV, same as their pickup) went into "limp home" mode when 
I called CQ on 20M with 100W into a Ham Stick mounted to rear side rail 
on the roof.? Top speed became 15 mph. I learned this while driving I-80 
through the Nevada desert between Salt Lake City and Reno. Not a great 
place to break down. I got running again by pulling the positive lead 
off the battery and reconnecting it, which rebooted the victim computer.

But this is an RF problem, NOT a power problem.? When we run mobile, the 
only chassis bond that matters is the bond of the coax braid to 
conductive parts of the vehicle at the antenna. This provides the 
antenna with a counterpoise -- that is, the vehicle becomes a very 
necessary part of the antenna. This causes RF current to flow on those 
conductive parts of the vehicle chassis and body -- IF those body parts 
are connected together. And that's a BIG IF, because most body parts are 
insulated from each other by PAINT!

I agree that I wouldn't power anything bigger than a talkie or receiver 
from a lighter plug.? FAR better to run a beefy copper pair directly to 
the battery. NEVER, NEVER use the vehicle chassis as a return for DC. 
Doing so causes the positive lead to form a large magnetic loop with the 
chassis return, AND causing it to act as an antenna.

Again, the radio is NOT the sensitive element here, it's the ANTENNA, 
which includes the chassis and other conductive parts. It IS important 
that -12V be bonded at the battery, but it is NOT useful to bond the radio.

My RV has a 3 KW inverter; I've not noted noises from it on any band but 
it was NOT cheap and it has it's own battery supply (not the house 
battery) and the radio has it's own battery supply.? There is no 
physical contact, only proximity.

We're not in disagreement here but we're approaching it from different 
angles (you have the formal training, we both have some experiences).

My rule:? Bond EVERYTHING to the chassis, including chassis elements to 
each other (paint is a pretty good insulator).? While that does have a 
*small* effect on noise (the every wire IS an antenna consideration); 
mostly bonding is to keep the RF (more correctly RFI) out of systems 
where it doesn't belong , including induction and radiation along the 
power cabling; to radiate from the antenna (while power sources are also 
another good place to provide some twist in the cable).? More bonding 
means more energy to the (intended) antenna and higher efficiencies.

When running >QRP the radio bonding can greatly reduce the effects in 
the radio from RFI.? Simply bonding the 200W RF deck in my truck to the 
chassis removed >90% of the RFI (except 40 meters sometimes turns off 
the cruise control).? The control cable and the mic cable each have 
ferrites in place; they weren't enough.? So we will disagree on your 
last point; my experience in that install provides that. It's all within 
7' of the antenna, hard to keep that any cleaner with that level of 
exposure.

The good news is that the newer vehicles have less cabling since wiring 
is replaced with fiber optics.? The bad news is that there is more 
'stuff' in a newer vehicle to generate and be sensitive to RFI.? I'd 
score that as a wash.

If your intent is to operate portable (buddipole in a parking lot) as
opposed to mobile, then none of the issues you described about bonding,
ferrites, vehicle electrical systems, etc come into play anyhow. Just use
the 12v from the vehicle battery (fused of course).
You can operate quite awhile that way even with the vehicle turned off to
eliminate electrical noise from the vehicle.
All built in inverters that I've seen in vehicles require the vehicle to be
running. Most are relatively limited in power handling as well. If you do
decide to plug a power supply into that vehicle inverter, make sure the
inverter can handle the load. I don't see that it makes much sense to go
that route, though.

I?m curious for the bonding guys..
Are you connecting the ?ground? of the AC mains to the ground of the 12VDC as well as the ground on the inverter?

Try holding the ALT key while typing 253 to get the exponent as in "IR?"
Similarly, ALT 0185, then 0186 for "XX??".

I'm not sure this works with all systems, or, if it even translates correctly, but in my DELL running Outlook, I have access to a whole bunch of handy items by holding down the ALT key while typing a 3 or 4 digit number. 
For example:  ?, ?, ?, ?,  ?, ?, ?, ?,?, ?, ?,?, ?, ?.

Overall, not a great plan.

Using an inverter, you will introduce RF noise, generate heat and poor regulation, unless you get a quality inverter (not cheap).  It's inefficient too and space wasteful.

If you use a power port (no longer called cigarette plugs), you will again introduce noise for your radio because they seldom have decent chassis bonding.  They are also low amperage capable and you can exceed that (check the owner manual or the fuse block), even if momentarily. Often they are also part of the vehicle systems array, so you'll get noises and generate issues to/from the vehicle electronics, some of which are rather spendy to repair.

In the long run, it's best (and least expense) to simply run the (fused at both ends, both wires) power cable to a known, chassis bonded source.  Power is NOT a place to cheap out.  If you're QRP, it's simple, the wires aren't huge, check your IR^2 losses over the run (make sure there is no voltage drop AT the radio).

Hint:  Make sure EVERYTHING, power at the source, power at the radio, the radio itself AND the antenna are properly RF bonded (not DC) to the vehicle and you'll have less issues, which translates into more fun.

It IS critical that all conductive parts of the vehicle be bonded 
together. It is critical for two reasons. First, because those parts 
carry antenna current on both TX and RX, and to be effective as a 
counterpoise, they must have good electrical contact. You're absolutely 
right about paint. It's a HUGE issue.

Second, good EMC design calls for cables supporting signals for 
sensitive circuits to be run in close proximity to a "ground" plane. 
Noise current is coupled far better to the much larger ground plane than 
to the cables. But this falls apart if there is a break in the "ground" 
plane, greatly increasing coupling to/from those cables. This mechanism 
is a likely cause (or contributing cause) to my 20M RF locking up the 
computer in my Toyota.

And, of course, it has long been good practice to bond the tail pipe to 
minimize old fashioned automotive noise. :)

Subject: [Elecraft] SPE 1K-FA Amp hookup and ALC Question
Message-ID: <1bf2f232-a8a9-6303-5b86-35908d50442b@montac.com>

I'm being given an SPE 1K-FA for use with my fully current K3s.

I'm being told that the K3s and SPE don't play well together using "ALC".
A conflicting report is telling me that Elecraft addressed the ALC issue.

Is this a resolved issue or not?? Can anyone provide any info on this?

I am going back into the K3s manual for 3rd party amp connection and 
pinout info to produce the cabling required to accommodate the amp/P3, 
etc...

Thanks in advance!

73,

Frank:?? Are you referring to AC ground {green wire} or AC neutral 
{white wire}?

In my installation the battery negative is connected via a green wire to 
the trailer frame.? The battery negative is also connected to the DC 
distribution panel via a #4 black wire.??? From the DC to AC inverter, 
the AC ground terminal is connected to the trailer frame and the AC 
neutral goes to the AC power distribution panel neutral buss bar just as 
a residential home.? In effect the AC neutral is not connected to the 
trailer frame.

Any discussion of mobile operation ought to include the bands in use. 
VHF/UHF is VERY different from HF with respect to RFI. My earlier posts 
in this chain have been with respect to HF. It's been a LONG time since 
I've encountered vehicle-related noise issues on VHF or UHF FM. I HAVE 
encountered noise from noise sources plugged into lighter plugs. :)

Ted, KN1CBR

It seems to me simpler to set up a source of 13.6 vdc to power your 
SUV "portable" station.  Running dc leads from the vehicle battery is 
simplest but you need to guard against discharging it so much that 
the vehicle will not start.  With engine running you will get about 
14.2vdc at the battery which will only help (but your gas mileage will suffer).

But using dedicated 12v deep-cycle battery for the radio will insure 
against starting issues.  Not sure if you plan to install radio in 
SUV or just have it to set up on say a picnic table or folding 
table.  If the latter, the battery can be situated close the radio 
and use the standard dc power leads of the radio equipment.  You can 
recharge the radio battery when driving or just running engine in CG 
by use of some No. 12ga wire from vehicle battery to the radio 
battery (good for up to 10A charging current if under 20-foot 
length).  Use a isolation diode if you don't want the radio battery 
involved in starting (which draws probably 200A from the vehicle 
battery).  Probably a 10A diode would suffice for charging the radio 
battery.  Wire up the system and measure current using multimeter to 
be sure before getting a diode.

This will not keep the radio battery from discharging when operating 
100w on HF because the radio is probably drawing 15A on peaks.  If 
recharging only when driving it will likely take close to an hour for 
full recharging (depends on the volt-amp rating of the radio 
battery).  I used a system like this when living in a remote cabin 
without power.  It look about 45 minutes running the truck to 
recharge the cabin battery (which was placed in the truck with wiring 
for this purpose).  I had a 100AH Marine Diehard (Sears) battery.

Diode will not keep from discharging the vehicle battery so have a 
way to disconnect the radio battery when operating (unless you plan 
to keep engine running).  Marine electronic shops stock things like 
dc disconnect switches and isolation diode units if you do not want 
to make your own.  Also several ham suppliers handle such items.

Last year I bought a new 4x4 pickup and installed ham radio equipment 
(KX3 + KXPA100, etc.):
http://www.kl7uw.com/Mobile.htm
Truck has two batteries (diesel) so I did nothing but run off one of 
the batteries (but I used No. 8awg).

Clay,

You must have been reading some very old information.  The first K3s had 
positive going ALC, but it changed to negative going early on.  If your 
K3 was shipped prior to Dec 10, 2008 (before approximate SN 2362) it may 
still have positive ALC.  If you have the REMIOUPGD or the Rev B KIO3 
board, it is ready to o with negative ALC.  If not obtain REMIOUPGD mod 
and install it.

Don W3FPR

Gerry,

The KX3 can be used at up to 15 watts for all modes below 20 meters. 
Above that band it is reduced to 12 watts.

Jim -

Good ideas from you, as always.

The impact of RF on the car's systems interests me the most, as I hadn't thought of it before.  Yours was a Sequoia.  Mine will be - if I buy it - a Lexus GX which is effectively the Sequoia's cousin, if not half-brother.  So even if I conquer all the challenges of bonding and antenna-making and all the rest, there is still the risk that HF RF will affect some processor on the vehicle at the worst possible time and place?  How do we deal with that sort of problem?  Operate QRP only?

Many years ago (1973) I had a HW-101 in a Fiat Spyder, which in those days still had the traditional coil and condenser ignition system.  To control noise I installed coax  braid over every spark plug wire from the distributor and the line from the coil and whatever else I could at.  Then one day the braid shorted something at one end or the other - right at the point where the Hollywood Freeway goes through Cahuenga Pass and (in those days anyway as I remember it) narrows to three lane, and at about 5:30 PM.  With a cold dead Fiat I blocked at least one of those lanes for at least the hour it took me to rip out all the braid while suffering the horns and the hand gestures of about 400,000 people whom I made late for dinner.

I don't want to ever do that again.  How vulnerable are today's cars' systems to HF RF?

1971 Plymouth Sport Fury
FT-101E mounted over transmission hump
Power cable direct from car's battery to rig
Hustler rear-deck-lid-mounted antenna
Many 140-watt HF CW QSOs
No problems with any function of the car itself

1980 Chrysler Cordoba
FT-101E mounted over transmission hump
Exactly the same set-up and connections
No problems with any function of the car itself

1984 Oldsmobile 98 Brougham
1989 Cadillac Sedan DeVille
1992 Cadillac Sedan DeVille
1994 Cadillac Fleetwood Brougham
1996 Cadillac Fleetwood Brougham
Raising kids, no rig in any of the above cars

2000 Cadillac DHS
FT-100D under-dash mounted
Many 100-watt mobile CW QSOs, hundreds of VHF/UHF FM QSOs
Power cable direct from car's battery to rig
ATAS-120 mounted on left side of trunk lid for HF
Comet 5/8 wave dual-band mounted on right side of trunk lid (VHF/UHF)
Diamond-K400 trunk mounts for both antennas
One-inch braid between trunk lid and something very metal and 
substantial (can't remember what) inside the trunk
No problems with any accessories, navigation, or display screen at 
either 100 or 50 watt levels

2006 Cadillac DTS
FT-100D under-dash mounted
Same set-up and connections
No problems with any accessories, navigation, or display screen at 
either 100 or 50 watt levels

2010 Mercedes-Benz E550
FT-857D control head in dash, RF deck under seat
Exactly same set-up and connections
No problems with any accessories, navigation, or display screen at 
either 100 or 50 watt levels

2017 Lincoln Continental
FT-857D control head in dash, RF deck under seat
Exactly same set-up and connections
Running only VHF/UHF at 50 watts so far
No problems with any accessories, navigation, or display screen

Not being an E.E. and not knowing any better, I probably did it all wrong.

minute or so rebooted the seat computer and it began working. A 40W 440 
MHz transmitter affected the cruise control in a 1991 Ford Ranger. 
Fortunately, it just disengaged it rather than setting the speed target 
at 120 mph.

I got a 2017 Honda Ridgeline last Feb, I'm still working through 
understanding the "UI" for it, but given how much automation is 
involved, I will not put HF mobile in it.? Automobiles have changed 
since Dad let me put the PE-103 powered 10m transmitter in the trunk of 
the family Plymouth.? The seat computer in the Chevy [one of seven in 
the truck not counting whatever was in the radio] had 320 KB of ROM, 64 
KB RAM, and cycled at 100 ns, all just to move the seats back and 
forth.? The Apollo Guidance Computer had 32 KB of 16-bit hardwired core 
memory, 2 KB of read-write core, and cycled at 10 ms for most 
instructions, to go to the moon and back.

I owned one of these amps for a few months, having bought it to get more 
power on 6M than the KPA500 did.? I didn't like it much. You probably 
know that ALC should NEVER be used between a rig and an amp to set the 
output power. That's a recipe for creating harmonics, clicks, and 
splatter. The right way to do it is to reduce drive power. If you're 
going to use ALC at all, set output power by reducing drive and use ALC 
ONLY to protect the amp when something goes wrong with an antenna (like 
the operator connecting the wrong one). :)

I agree with Jim, K9YC on the ALC points.

With older radios, namely tube types which required the exciter PA to be 
loaded correctly to be linear, this power level would overdrive many 
amplifiers. ? Hence ALC from the amp to the transceiver/transmitter was 
required to control the drive power.

Today's radios have much more accurate power control methods. These 
methods are far superior to those found in most amps. ? Most solid state 
amps have adequate protection with regard to overdrive, again ALC from 
the amp to the radio is not needed. And as Jim indicated, if one chooses 
to use ALC from the amp to the transceiver and it is not properly 
adjusted, one can expect signal report issues and unfriendly neighbors 
on the radio spectrum.

In the late 1980s WB6FDR showed me his mobile station that had a Kenwood 
rig with a small control head which he had mounted on the dash of his 
Mercedes.? The rest of the rig plus a KW amp all fit in the trunk.

I recall that one of the old W6SAI handbooks showed a mobile rig with an 
amp that used water cooling.

I have an SPE 2K-FA I'm using with a K3S... very happy with it.  I made a
verbose YouTube <https://www.youtube.com/watch?v=Ku8Gyl0amRY> video early
on after I received the amp which gets into the details of making the
interface cable.  (these days guys can pass the Extra Class exam but they
can't make a simple interface cable to an amplifier... ;) )  All of the
details would apply to the 1K-FA.

As others have stated, don't use ALC on the K3 to control the output of
your SPE amp, however it is viable as a safety measure to let the amp drop
the K3 output if it's software deems necessary. (despite what you will read
in the SPE manual where it says just crank the power output on your exciter
all the way up and let the amp control the output via ALC)  I get into the
details around this in the video several times.  You can fast forward and
find the areas you are interested in related to the cable interface to the
K3.

Here is the link to the video again... I hope you find something helpful...
related to your 1K-FA.

My friend had a jeep wrangler (2012 model IIRC ) that we used for VHF
roving with no issues. When we tried the same vehicle on HF, some bands
were ok and some caused havoc with the vehicle electronics. Transmit on 15m
at 100 watts triggered the wipers... 40m lit up every indicator on the
dash.
We switched to my 2015 F-150 with almost all the options, and have no such
problems. Same rig, same antenna. However, the truck creates some hash in
the HF receiver. So, there can be a lot of differences between vehicles.

I recall a construction article a long time ago (mid 1960's) in GE Ham 
News where W8DLD constructed a 1KW mobile linear using a pair of 
Grounded Grid 814 tubes and developed the HV from a modified alternator 
to bring the 3 phase AC out and run it to 3 transformers.

Of course, in those days, there were no computers in vehicles to be 
concerned about, and there was plenty of room in the vehicle to mount 
the exciter, usually under the center of the dashboard.  Remember that 
the Collins KM1 and KM2 were designed as mobile transceivers, and they 
were much larger than the K3.

Yep...? Thanks Jim...? I had remembered reading about this, but not 
having an amp at the time, I glossed over it.

Thanks to re-reading manual and Fred's book, AND to several responses, I 
am fully informed now!


Case closed.... :-)

Back in the late 1960's, I ran a SBE 33 and a HW12 compact kilowatt in a Ford Econcom PU, with a Texas bug catcher antenna and NE2s around the Top Hat.....? HP pulled me over and said I could not do that, causing drivers to swerve all over the place behind me...... FUN.

My friend had a jeep wrangler (2012 model IIRC ) that we used for VHF
roving with no issues. When we tried the same vehicle on HF, some bands
were ok and some caused havoc with the vehicle electronics. Transmit on 15m
at 100 watts triggered the wipers... 40m lit up every indicator on the
dash.
We switched to my 2015 F-150 with almost all the options, and have no such
problems. Same rig, same antenna. However, the truck creates some hash in
the HF receiver. So, there can be a lot of differences between vehicles.

There's nothing like doing the job correct, and Kent's installations 
seem to indicate such.

I've used my Tentec 599 Eagle in my 2005 GMC Somona with a Hustler array 
on the rear, power cables direct to the battery.? No issues any band 80 
- 6 meters.?? Same basic configuration and installation in the travel 
trailer.? It does however slightly "modulate" the interior LED bulbs on CW.

Subject: [Elecraft] K3 - Major Firmware Update
Message-ID: <000101d3415c$86f0efd0$94d2cf70$@STL-OnLine.Net>

My K3 is sn 14xx and has not been upgraded since the K3S and the new
synthesizers came out.  It is running fine but I wonder about updating the
ucode because the new stuff is not in it.  I also have not updated my K3
Utility.  

 

IF I am going to update the firmware, I suppose I should get the newest
Utility and then go ahead and just do it all at once from 4.86 to 5.60 and
all the others too.  They all have new versions.

 

Is this dangerous?  Will I kill my radio?

 

Is there any advantage for me to do so as I have not put any of the K3S
stuff in my radio?

 

Should I do it anyway?

 

Thanks, 73, Jim KG0KP

For the K3S, I suggest reading Fred Cady's book, specifically page 170 
{9.2 Automatic Level Control - ALC} , page 222 {To ALC or Not to ALC}, 
and page 291 {EXT ALC} for particulars.?? In summary, Elecraft does not? 
advise using ALC from the amp.

Personal opinion, the amp should provide adequate protection for high 
SWR and excessive drive.?? It should not rely on other means for 
protection.

Update to the latest utility version first.  Then, just put up the LATEST firmware version.  You don?t have to do all of the intervening releases.  No, it won?t kill your radio.  Make sure you read all of the release notes since whatever version you have installed.

Jim,

The K3 Utility sorts all that out.  Upgrade the firmware and keep it 
upgraded periodically.  Save a configuration file before and after this 
upgrade.

Look at the Firmware Release notes between your existing firmware level 
and the current version to see what has changed.
The Firmware Release Notes are an effective "addition to the K3 manual" 
do not skip that information.

Make sure to read the release notes, as I know if you are updating a certain
version, you will need to do the calibration again, so a dummy load is
needed.

It's all pretty much guided by the utility, make sure to download the newest
K3 utility first, then do the update.

My K3 is sn 14xx and has not been upgraded since the K3S and the new
synthesizers came out.  It is running fine but I wonder about updating the
ucode because the new stuff is not in it.  I also have not updated my K3
Utility.  

 

IF I am going to update the firmware, I suppose I should get the newest
Utility and then go ahead and just do it all at once from 4.86 to 5.60 and
all the others too.  They all have new versions.

 

Is this dangerous?  Will I kill my radio?

 

Is there any advantage for me to do so as I have not put any of the K3S
stuff in my radio?

 

Should I do it anyway?

 

Thanks, 73, Jim KG0KP

A memory:
1955 I was at the Virginia Phone Net picnic at a farm. A guy pulls up in a Plymouth coupe with a huge plastic box on the roof with large coils and capacitors showing. Sticking out of it was a long vertical antenna.
He stepped out. He had a microphone harness on which had probably been from the Navy. He pushed a button on it and a huge whine erupted from the trunk. He then pointed a piece of wood near the vertical and drew a tremendous arc to it.
He opened the trunk and we saw several large dynamotors and many batteries. Yes, he had a 75M kilowatt AM rig. Pretty amazing.

I ran a similar setup. I built a homebrew version of the HA-14 (HW-12 was a xceiver). Same 572B tubes and powered it with Heath's DC power supply for the HA-14. Plate voltage was around 2200 volts. Drove it with a National NCX-3 in a brand new '65 Dodge R/T. Antenna was also homebrew.

I never had a problem drilling holes in new cars. Do a neat job and it's easily repaired when you trade it. I never had a problem at trade-in time.

Simpler cars in those days. Even my bike is computer controlled now.

My friend had a jeep wrangler (2012 model IIRC ) that we used for VHF

were ok and some caused havoc with the vehicle electronics. Transmit on 15m
at 100 watts triggered the wipers... 40m lit up every indicator on the

We switched to my 2015 F-150 with almost all the options, and have no such

the HF receiver. So, there can be a lot of differences between vehicles.

Those were the days when a mobile operator would make his engine stall by pressing the PTT when the engine was idling at a stop light. 

One guy I knew tore out the whole back seat of his sedan and filled it with a KW AM rig (bachelor of course). His mobile antenna featured a copper toilet tank float on top to avoid corona discharge on transmit. 

Back then RF radiation levels were consider harmless at any level or frequency. There is the well-documented story of the Microwave engineer at Raytheon who discovered a chocolate bar in his shirt pocket suddenly melted. He figured out that he was standing in front of the open port of a magnetron. And the "Microwave Oven" (back then a "Radar Range") was born. 

Working at Lockheed Aircraft Service one night on the F-86 flight line I thought I was coming down with the flu because I was suddenly sweaty on a cold, winter night. Then I noticed that the fire control radar on one of the F-86's nearby with the radome off was "looking" right at me. I moved several meters to one side and the dish followed me. I was being irradiated by the RF, raising my body temperature. I just moved further away. No one thought that was remarkable. 

We have become much more sensitive to such things. But it was not always so, even for the current generation of Hams.

I recall a construction article a long time ago (mid 1960's) in GE Ham News where W8DLD constructed a 1KW mobile linear using a pair of Grounded Grid 814 tubes and developed the HV from a modified alternator to bring the 3 phase AC out and run it to 3 transformers.

Of course, in those days, there were no computers in vehicles to be concerned about, and there was plenty of room in the vehicle to mount the exciter, usually under the center of the dashboard.  Remember that the Collins KM1 and KM2 were designed as mobile transceivers, and they were much larger than the K3.

That is a mystery.
The KPA500 is simply an amplifier, so it should amplify the K3S PEP 
power for SSB the same as it does for CW.
Take a look at the drive power from the K3S.  If you are overdriving the 
KPA500 in SSB, it may be switching in an attenuator.
That could result from having too much compression on your SSB setting 
in the K3S.
Have you set the PER BAND power in the K3S to limit the power to the 
KPA500 when in operate mode?  See the KPA500 manual pages 9 and 10.

Most likely, the AC inverter built into the car does not produce a sine 
wave, and your radio probably won't like it.

You could just connect some heavy wire, with a fuse, directly to the 
battery terminals, and run the radio on that.? However, car batteries 
don't deep cycle well at all, and there's the chance of not being able 
to get the engine started.? You can buy a small, 30 AH deep cycle 
battery, which will run a 100W radio for some hours of normal 
operation.? A voltage booster will step the voltage up to 13.8 V, so the 
transmitter will operate at full power.? One big advantage of the 
separate battery is that you can carry it a ways from the parking lot if 
you have to.

Charging the battery from the vehicle is a bit tricky, though. You can't 
just connect it in parallel with the vehicle battery, as the alternator 
will charge it at much to high a current.? I was unable to find an 
affordable commercial device that could safely charge such a battery 
from the vehicle.? One could build a current limiter, but it would take 
some effort.? For me, the path of least resistance was to buy a 120V 
battery charger, and run it on a 150W sine wave inverter I already had.? 
(Using the above connections to the vehicle battery; that's a bit much 
for the cigarette lighter plug.)? Such a charger may or may not work 
with the built in inverter in the vehicle.

Yes. BUT -- that was a brand new 2006 model. Let's hope Toyota/Lexus has

I'd say it's a business problem -- that is, between you and 
Toyota/Lexus. It might be worth checking with ARRL about HF mobile in 
current production of these vehicles. MAYBE things have improved. After 
having the issues with my SUV, I did a lot of poking around online and 
found indications that another brand was far better for RFI. But by then 
I'd made a bunch of trips from W9 to W6 and had 45,000 miles on it. :)

That's a good question to poke around the internet in general and ARRL 
in particular.? Also ask the guys who do serious mobile operation during 
state QSO parties. W0BH, W4NZ, KU8E, and K4ZGB are some guys who have 
done a lot of this.? They also know how to put out a good signal from a 
mobile -- I've worked several mobiles from TN and GA on 80 CW, including 
K4ZGB last month in the TNQP.? And they will have also solved any issues 
with noise from computers or computer power supplies.

Marvin;

Assuming that you have the AUX I/O cable connected from the KPA500 to the K3, and you have RADIO set to K3 in the KPA500 menu, then I suspect you have dialed the power down to 0 on the K3 when the KPA is enabled.

The KPA tells the K3 its state when it switches to STBY or OPER. The K3 uses this info to set the power level when you have the K3 set for PER BAND power as Don mentions. I don?t know if the per-band setting for power includes mode,
but since this is one of the few things the K3 does when the KPA changes its operating mode, it makes sense that the problem is a very low power setting in the K3.

If this isn?t the situation, be sure to check the AUX I/O cable to make sure that none of the pins are bent. Also make sure that pin 11 of the connector is missing. If it is not, then I would suggest that you might want to remove it and/or turn off the DIGOUT1 signal.

Other than that, Don is right. This is a mystery.

Message-ID: <r470Ps-10126i-8083D4E76B8549ED9B650AD0D0F9938C@Williams-MacBook-Pro.local>

I was using my KX3 to operate QRP during the California QSO 
party. I had my logging program (RUMlogNG on a Mac) connected 
through the PX3 to the KX3 using an Elecraft USB <--> RS232 
interface cable.

I noticed the computer was not getting the band and frequency 
information from the KX3. When I unplugged the PX3 from the KX3 
and connected the computer directly to the KX3, the computer got 
the frequency/band information correctly, so the PX3 was 
involved in the problem. I spent the rest of the contest 
swapping the plugs in the KX3. :-(

The computer <--> PX4 <--> KX3 combination has worked in the 
past. Is there something flakey in the PX3, of have I set some 
configuration parameter badly? Or? Does anyone have any ideas?

Bill, I use exactly the same setup, and I just verified mine is working,
even after "High Sierra" upgrade.?

I had that problem when I first set it up and the problem was in the
Serial speed in RumlogNG? <TX1> in my case.?

My speed in rumlog was differtent than the speed on the PX3.? Since it
goes there first before the KX3, The PX3 will not pass the bad baud rate
date to the KX2, I set all of my speeds to 38,400, RumlogNG, the PX3 and
the KX3..

hope this fixes your problem also..?

Hi.

I haven?t seen "Kent's instructions", but running the radio -ve power
lead direct to the battery when the radio also has a "Ground" at the
antenna, could result in the destruction of the radio and/or antenna
cable, if the battery ground strap to the vehicle frame goes bad.???
That is not so uncommon as you might think, even on modern vehicles.

Think about where the engine starter current (and alternator produced
charging current) ideally flows, and where it will try to go, if that
ground strap is at all compromised (usually by corrosion, but could be
less than well re-fitted after some maintenance work.)? Meanwhile, you
have provided another battery ground route via your prized radio, and
antenna cable.

The rig -ve lead to be safe, should go to the vehicle frame to prevent
such disaster, NOT directly to the battery -ve terminal.

I've seen a simple CB radio explode under those circumstances and burn
out the car interior.? (I was involved in helping put out that fire with
portable extinguishers that were available.)

I've also personally experience a vehicle electrical fire while driving
(not radio related) and it's not pleasant in any way!...

If you *Must* wire the radio -ve power lead direct to the vehicle
battery (a temporary install for Emcom etc) include a fuse in that -ve
lead, and also make sure that the ground path via the radio and antenna
etc, can take the fault current without damage before that fuse blows!

This is not an EMC/RFI problem, it is a fire safety issue.

Note too, that many modern vehicles incorporate a form of regenerative
braking using the alternator to provide more retardation when you lift
off the throttle at speed.?? That can (does) raise the battery voltage
quite a bit, some not so modern (but expensive to repair/replace) radio
kit might object to that.

Also, for that very reason, the battery is rarely charged to more than
about 70% of it's ultimate capacity, to provide "space" for such regen'
braking action generated energy.

It is unlikely that current vehicle build principles are that different
between the US and UK (or rest of the world for that matter) in this
respect.

Stay safe.

73.

Dave G0WBX.

All,

Dave is correct, but the point where the negative lead is connected 
should be near the battery, not in the cabin where there may be 
unexpected resistances because of adjoining body panels.

If you are diligent about bonding the various panels together, then you 
can connect the radio negative almost anywhere, but still near the 
battery is the best choice to assure a low resistance connection.

Don W3FPR

Elecraft is on the Monterey coast (generally speaking) near what (in the 
business of firefighting) is known as the asbestos forest (it burns so 
rarely but when it does... wow!).

They're as safe as they can be for any business.? The staff homes on the 
other hand...

Elecraft is in Watsonville CA, a bit inland from the Monterrey/Santa 
Cruz area [and famous for artichokes]. The SoCal fire(s) is/are east of 
Los Angeles, about 350-400 miles south.? The NorCal fires are in Sonoma 
and Napa counties [so far], maybe 100-120 miles north or so.? Several 
members of the NorCal Contest Club have lost their homes.

I'm one of the Elecraft engineers who lives at a remote location.

My house NE of Santa Rosa is still standing.  I evacuated my house 
yesterday at 3 am (I could see the flames on the top of the ridge a few 
miles away) and I spent yesterday morning and afternoon doing emergency 
communications at the Sonoma County Operational Area Emergency 
Operations Center.  I had been awake for almost 48 hours by the time I 
got to bed last night at a friend's house.

Today I was able to return home and am running the generator to get the 
fridge cold again and re-fill the water tank from the well.  I have a 
number of friends who have lost their homes so I count myself very lucky.

I don't live in California but I have driven all through the area.

Elecraft is located near the coast north of Monterrey and south of Santa Cruz.  This is as I recall very roughly 50-100 miles south of San Francisco and a couple hundred miles north of Los Angeles.

Most of the fires are either in the California wine country, which is north and east of San Francisco, or in southern California, near Los Angeles.

Watsonville is itself located in a valley and there is probably relatively little vegetation in Watsonville itself to fuel a fire.

This area involves the beginning of a climate transition zone.  Southern California can get very dry along the coast.   This area is high risk for fires.

The north/central California coast is heavily influenced by cool, moist marine air.  The forests in this area tend to be relatively wet and fires are more rare.  For example, in San Francisco, temperatures can be 20 or more degrees cooler than in Oakland across the bay and dense evening fog is common.

As you go north in California into Oregon and Washington, where I live, forests on the coast get wetter and denser.   Forest fires in the coastal areas are extremely rare and unusual.  Conditions are almost always too cool and wet.

In central/northern California, Washington and Oregon fires tend to happen in the drier, inland areas.

where the southernCalifornia fires are in relation to the factory.

Fortunately, we live 60 miles south of San Francisco and the fires (so far) are north of the city.? Drift smoke is down though and we woke Monday to its smell.? Shouldn't taint the remaining fruit we're harvesting today and Thursday.

Message-ID: <1507670178312-0.post@n2.nabble.com>

In preparation for the arrival of my KPA1500 I was wondering if a simple
two-port VGA switch would be the best approach for switching the ACC/AUX
line to allow the selection of the KPA500 or the KPA1500.  Or is a simple Y
cable ok?  Pin 10 PTT would be open ahead of the switch or Y cable to allow
continued use of the keying line which is switched among two amps currently
- soon to be a third.

I assume at some point the KPA1500 will just become the only amp connected
but in the short term a lot of A/B testing will occur so I'm just looking
for the simplest means of accommodating both the KPA500 and KPA1500 without
moving the ACC cable back and forth.

Roger,

I assume you are using AFSK A data sub-mode.  Check the data submode to 
be certain.

Do you have anything other than the soundcard audio lines, the RS-232 
computer connection, the DC power cable, the wattmeter and antenna (or 
better yet a dummy load) connected to the K3?
If so remove everything except those items.

It appears you have the audio set about right, although the 5th bar 
should be only flickering, not on solid.

Try again with the bare K3 and see what happens.  If you have the KAT3 
installed, do an ATU TUNE into the dummy load to set the L/C components 
to match the dummy load.

73,
Don W3FPR

Dan,

Some "VGA" switches switch all 15 lines while others do not.
You need one which switches all 15 lines.  Be certain before you buy.

I tried it in LSB mode and it works fine! I checked and both the CW and SSB 
fikters are selected for data mode.

Roger,

That statement does not make a lot of sense - explanation below:

With the K3 (and K3S, KX3 and KX2), there are no specific CW and SSB 
filters - as there is with the K2.
The DSP filter bandwidth is set with the WIDTH/SHIFT (or HI CUT.LO CUT) 
knobs and any roofing filters will switch in and out as the bandwidth is 
changed.? The bandwidth is what you select with the two knobs (stay away 
from the XFIL button).
The default width for AFSK is narrow - but that applies to receive 
only.? Tune in a single RTTY signal with the VFO and look for the decode 
in MMTTY if using it that way.
If you are using a waterfall display, then you would normally set the 
bandwidth to something resembling the SSB bandwidth of 2.7 or 2.8 kHz.? 
Set the DSP filter bandwidth according to the method you are using for 
RTTY (either click on a waterfall or tune to the RTTY signal with the 
VFO [when using a narrow bandwidth]).

For RTTY, use AFSK A since you are using the soundcard.? It turns off 
compression and sets the TX and RX EQ to flat automatically. AFSK A 
defaults to LSB which is standard for RTTY.? Your compression and EQ 
settings for SSB will remain the same and there is no need to set them? 
to off (flat for EQ) when using DATA modes.

The receive filter width means nothing for transmit, the 2.7 or 2.8 kHz 
filter should be selected for DATA mode transmit.? Use K3 Utility to 
check the filter that you have enabled for transmit in DATA modes - it 
must be the 2.7 or 2.8 kHz filter.

Don W3FPR

NCCC is a wide area contest club centered around San Francisco. Several 
of our members around Santa Rosa/Petaluma/Healdsburg have lost 
everything, and the fires there are completely out of control. So far, 
all are safe.

Although you may use a different combination of ACC signals than me, FWIW I
routinely parallel multiple sets of accessories off my ACC connector. When
I'm operating remotely, I have two band decoders, a RemoteRig box, and a
KPA500 connected. No switch, no problem.

If you're using circuits I'm not and have a problem, note that many VGA
switches don't switch all 15 lines.

Hi All,

I have for mobile / portable a K3 of the old vintage that I am thinking 
of passing on and getting either a KX2 or KX3. I dont need the 100w so 
either should be ok but I wonder which any of you more active outsiders 
would recommend. Also I notice Elecraft gear sells very quickly in the

Any suggestions or help gratefully received.

Sad news.? Glad to hear all the NCCC members are safe.

I fought wildfires but nothing like those.? We had one in Montana in 
2006 but I became a FF after that fire.?? The 2006 fire burned over 100k 
acres and took about 30 homes and buildings.? Montana does not have the 
housing density that CA does.? We lost an engine in that fire when they 
could not see the road from the heave smoke and rolled it into the 
Stillwater river.? We could have lost the entire crew.? A few sustained 
injuries but we were lucky.

When they tell you to get out.? Please do.? You really don't want to be 
in the middle of it.

Stay safe!

Unless you install the new synth and DSP board, with possibly a few of the 
minor mods available from Elecraft, you won't get top dollar for your K3. 
However, I don't think you'll have any problems selling it. Just before the 
K3S was launched, I paid around ?1000 to a private seller for a K3, which 
I've since upgraded to almost K3S standard. There are a couple of UK 
Facebook groups for buying and selling rigs and of course there's always 
eBay.
Another place to advertise it would be RadCom.

The KX2 is smaller and lighter. The KX3 covers more bands. Both 
are harder to switch between SSB and Data modes than the K3.

You make the call.

Anyone out there in Elecraft land have any Sommer Antenna manuals?? Any 
series...? but especially the 800 series.

I am trying to build an archive of information on the XP-50x, XP-70x, 
and XP80x series antennas, but also the T25(s) and the T-50 verticals.

Specifically, I am looking for complete, original printed manuals from 
Sommer, but beggars can't be choosers.? I will pay postage both ways, 
and with provide the owner with a high resolution version of the PDF 
created from the high resolution scans.

Hi All,

My condolences to anyone adversely affected by those fires.  From the TV coverage I?ve seen, they look absolutely horrible!!  

We are heading to Oregon next week, to visit our daughter, and I changed our normal route in order to go to Pacificon next week.  I suppose attendance may be affected somewhat by the fires.  After Pacificon, I thought I would do something different than I-5, and go Hwy 101.  However, that looks like It takes me right through problem areas.  So, that may get changed as well.  

Last month Oregon was burning up.  Now it?s California!  We seem to be having one disaster after another these days.  So many people are in trouble!  I think everybody needs to seriously review their insurance coverage!

Hope to see some of you in San Ramon!

73,

Dave W7AQK

My hopes and best wishes go to all of those affected or threatened by these fires.  We who live in Colorado understand the danger and the devastation.  My own home, my operating QTH, is in an area that has been redlined by every insurance company doing business in the state, save one.  Over the years I have been spared the destruction that licked at the edges of the ridge, miraculously on one occasion; but I have some feeling for what it must be like for those facing the same in California.   Wishing you the best . . .

Is anyone using ear buds with a microphone with their kx3? I am
contemplating buying earbuds and wondered if it would be wise to include a
microphone. If so recommendation of brands and models known to work well
would be appreciated.  Thanks, Marv KG7V

I bought the parts to make the adapter cable to use my cell-phone
earbuds on my KX2. I haven't built it yet.

I suspect that your voice won't be quite as full and up-front with the
earbuds mic vs. some other, but if you really need to travel light, it
should work.

Tony,

I own both.  For portable ops I'd go with the KX2 hands down.  Smaller and
better battery life on the internal battery.  My KX2 has been to SOTA
summits in Japan, Singapore, California, Texas, and Virginia, so it travels
great and takes up very little room in the small camera case that you can
order with it.  But hey, they're both great radios so you're not going to
lose either way!  Have fun!

Hi All,

I have for mobile / portable a K3 of the old vintage that I am thinking of
passing on and getting either a KX2 or KX3. I dont need the 100w so either
should be ok but I wonder which any of you more active outsiders would
recommend. Also I notice Elecraft gear sells very quickly in the States but
not too sure what the second hand market is like in the UK. 
Any suggestions or help gratefully received.

Oregon is still on fire, in spite of rains. The big fire in the Columbia River gorge (Eagle Creek fire) is only 5% contained. There are several others as well that will not likely go out until sometime over the winter months. 

The huge difference is that the Oregon fires are in mostly wilderness areas whereas the major California fires are burning through towns and cities. 

I have friends in the S.F. Bay area who have left for the Monterey area until the air clears (that might be a while). 

In spite of the long, boring ride through northern California, I recommend I-5 to I-504 to I-80 and then I-680 south across the Benicia-Martinez bridge to San Ramon.

Hi All,

My condolences to anyone adversely affected by those fires.  From the TV coverage I?ve seen, they look absolutely horrible!!  

We are heading to Oregon next week, to visit our daughter, and I changed our normal route in order to go to Pacificon next week.  I suppose attendance may be affected somewhat by the fires.  After Pacificon, I thought I would do something different than I-5, and go Hwy 101.  However, that looks like It takes me right through problem areas.  So, that may get changed as well.  

Last month Oregon was burning up.  Now it?s California!  We seem to be having one disaster after another these days.  So many people are in trouble!  I think everybody needs to seriously review their insurance coverage!

Hope to see some of you in San Ramon!

Subject: [Elecraft] K3S and P3 pinout/cable stuff... (How to drive yourself
 mad integrating an SPE amp into your system)
Message-ID: <84cc26d4-f32e-32e9-a273-ba427e3ec31c@montac.com>

In my efforts (more of a quest now it seems) to comprehend the K3s and 
P3 pinouts for RS-232 and ACC, et al., I have become convinced it is a 
conspiracy to drive me nuts.<grin>
Trying to figure this all out so I can build a custom cable to connect 
all the following with the indicated functionality:

K3s (to computer via USB, to P3 via CBLP3Y or NEW custom cable 
incorporating CBLP3Y wiring with additions to add SPE)

P3 (using CBLP3Y or custom to accomodate additional Y to SPE for 
RS-232/common)

SPE 1K-FA (CAT, KEY/RELAY, ALC (failsafe only), Remote On, and TX INH 
via CAT connector, AND RS-232 direct to computer via USB)

External Tuner (Denon MLT-2500 for now, Palstar HF-Auto eventually whent 
eh SPE will go in favor of a KPA1500 and this ALL becomes moot)

Questions:

1) Does the K3s adhere to RS-232 standards on signalling?
2) Is the pinout on the RS-232/P3 Port (8P8C, aka RJ45 jack) static, or 
do the signal lines change based on some logic setting in the firmware?
3) The E980297 cable (RJ45 to DE9F) pinout has DTR and RTS and the 
CBLP3Y does not....? Is this because when this cable is used, the 
connection to the computer is via a serial cable from the P3's PC port 
(serial)?? And with the CBLP3Y, the DTR/RTS traffic goes to the computer 
via the USB cable?
4) Is the K3S a DTE or DCE device?

The TXD/RXD/GND signalling appears to change depending on how the K3s 
"sees" the computer.? Or I am seriously confused... maybe both.? <smile>

_*Bottom Line:*_

Can someone give me a DEFINITIVE pinout for ALL 8 pins on the K3S' 
RS232/P3 Port?

Pin 1 is (appears to be secondary/second/#2) an RS-232 Common (ground)
Pin 2 primary RXD or TXD?
Pin 3 secondary RXD or TXD?
Pin 4 is (appears to be primary/first/#1) an RS-232 Common (ground)
Pin 5 primary RXD or TXD?
Pin 6 Secondary RXD or TXD?
Pin 7 is DTR
Pin 8 is RTS

Bottom of Page 19 in K3S manual gives the RJ45 pinout as follows when 
using the E980297 cable:

_*RJ45?????? ??? DE9F (P3 XCVR)*_
1 NC
2 RXD__________2 (RXD)
3 NC
4 Common_______5 (Common/GND)
5 TXD__________3 (TXD)
6 NC
7 DTR__________4 (DTR)
8 RTS__________7 (RTS)

I need to know what 1,3, and 6 are called on the K3S RS232/P3 (RJ45 port 
before I can figure out the rest of the puzzle.... they are obviously 
TXD/RXD/GRN set, and #1 is for sure the second ground as shows 
continuity with the other ground using a meter.? But it looks like there 
is either a traffic direction change on some of the signal lines or 
there's a wired in "null modem" crossover somehow when the computer 
connection goes from the serial cable between P3 and computer versus the 
USB cable between the K3s and computer.

Until I verify exactly what each pin is as connected with the CBLP3Y to 
P3 and USB from K3s to computer and which way traffic is flowing on each 
sig line, I won't know where to patch in the SPE's RX232 and TX232 lines.

Probably should have just had Dan Tassel make the cable(s), but I like 
making my own cables, and I want to go a bit beyond the "minimum".

73,

Clay,

Go to the Elecraft website, then go to the manuals section, then 
download the K3S schematics, then go to the KIO3B Digital I/O Module 
page.? You'll find two boxes with pin definitions for the connector in 
question.? And of course the K3S schematic set will allow you to follow 
them as deeply into the radio as you'd like, perhaps deeper :-)

Clay, you are doing the right thing to make your own cables.  Digging in
and learning all the details will pay off in the long run.  Plus, if you
buy a pre-made cable you will be at the lowest common denominator and end
up fighting it or re-working it down the road when you get new equipment.

Good for you for sticking with it and digging into the manual and details.

Max,  I agree with your wiring comment.  I have a Heil cable which was suggested for my Heil mic and the pin outs don't match anything I know related to the KX2/3.  Too bad the Co.'s don't manufacture to match different radios.

Subject: [Elecraft] Screen Magnifier for P3...user with poor eyesight
Message-ID: <1507852123023-0.post@n2.nabble.com>

I just acquired and added a P3 to my K3.  From all indications it works very
well but I find that with my aged and failing eyesight the screen is quite
difficult to read, for example, when setting Mkr frequencies and the center
frequency in upper center of the screen. I'm thinking there must be an easy,
cost effective solution.   I was browsing Screen Magnifiers on Amazon, made
primarily for cell phones mounted in a simple plastic holder which could be
implemented with a little imagination.  They seem cheap enough ($5 -$20);
just curious what the pluses and minuses might be.  Anyone?

Message-ID: <00A5504B370E45B1B94B97C634C1A325@Toshiba>

For the past month or so, when I turn on one of my K3?s, I sometimes get an ERR BP1 message.  If I then press DISP, I get a series of different error messages, and then finally the VFO B frequency is displayed, and the rig seems to work normally.  The sequence of ERR messages is
BP1
LPF
IO3
IF1
XV3
AT3
PA1
Normal Operation

If I turn off the radio and turn it back on again, thus far it has come up normally every time on the restart.

Any ideas about what could be causing this?  This K3 does not have gold front panel pins.  I was thinking of removing/reinstalling the front panel or repeating the calibration procedures.  Suggestions are welcomed.

Thanks.

My suggestion cost more but may work better. Order the ext video adapter for the P3 from Elecraft. Then also buy a monitor as big as you want.?

The best "screen magnifier" for the P3 is the SVGA option.  Put it on a 
monitor sized to your choice.

The place to start is putting the gold pins in your K3.
If that does not help, then contact support.

Message-ID: <CAODN=v2rabwWU+HCscYoe=D-pwkfvKmq0JuN28ynjxowz43K9A@mail.gmail.com>

Hi all,

I'm a very new user to the K3.  I just recently update the Synthesizer
board and added the KXV3B and the K144XV options to my K3.  I made all the
updates in Config to make this work.  Everything works fine.

The problem I am having is when the radio sits over night and and turn it
on, it doesn't receive or transmit at all.  The only way I can get it to
work is to start the K3 Utility and download and reinstall all firmware.
Once that is done, everything is working fine until I turn it off at night
and turn it on the next day.

I noticed there is a battery on the main board.  Does it sound like it is
dead and needs to be replaced?

I have not had a chance to check this.

Thanks for your help!  Please let me know if you have any questions.

Pete, I think you have misunderstood the purpose of the Key Out jack
on the K3.  It does not provide 12 volts out at 40 ma. It is a keying
circuit that can withstand a external keying circuit up to +200 volts
DC and can handle a keying load of up to 5 amps. (See the K3 manual
regarding the Rear Panel) If you want to key your external relay, you
will need to provide a source of power for the relay - and use the Key
Out connection as the "switch" for it.

I suggest the Fred Cady book.?? He has all the info shown in charts and

configured.?? I view it is too much work to try to figure out via a

I hadn't thought of that but, yes, the relay does need an external 12V 
supply.? There absolutely must be a diode across the relay coil to 
prevent the voltage spike at turn-off from exceeding the 200 V limit and 
shorting the FET.? For the 40 mA relay, a 3.3K resistor could be used in 
series with the diode to speed up the turn-off.

Hi Fred,

I see no-one has responded to you so I will chime in with what I know.

A few more details about what you actually see and hear when you press the
power button would be helpful. What you should see and hear is an almost
immediate relay click and most (all?) LEDs turn on. Fractions of of a second
later the display backlight comes on, then fractions of s second later the
display comes alive and you should hear audio. This machine boots up fast,
thank you, engineers at Elecraft.

If on the other hand, you see "CPU LD" (or something similar) in the
display, the software has decided that something is wrong with the
application software and decides to stay in the bootloader (modern firmware
always wakes up up in the bootloader and decides where to go from there).
That would explain why your only recovery is to reload the firmware.

I am starting to guess now and it's not always a good idea. One explanation
is that there is actually something wrong with the application firmware
(corrupted to some degree). But this seems improbable since you can
consistently recover by reloading it.  I assume you are turning the radio
off by using the power button. Another possible explanation is that the CPU
starts executing before the hardware has come up completely and thus
erroneously concludes that the application firmware is corrupted.

I realize that  none of these ramblings is a direct help to you to recover
from your situation but I am hoping it may trigger others to have an AHA
experience.

BTW, the battery is not essential to the K3 operation. It just powers the
RTC which is not very good anyway. I have plenty of better ways to tell the
time of day.

I would also comment with Knut, AB2TC, that one must always turn the 
radio on and off with the power switch.? This allows the internal 
workings to store the data.?? If you use a "master station switch" thus 
just dump the power supply then the radio may not store the data as 
required.?? I recall the term "power down imminent" or PDI.

Years ago we had "the big switch" which was used to shut the station 
down.? Today with all of the computerized gadgets, power down in 
sequence is more and more of a must do.

In another brand of radio to which I am familiar, there is a CPU timing 
circuit that assures the CPU is up and running before loading the 
operating code.?? If this circuit is running too fast, it may cause a 
partial load and related error.? This circuit is basically a simple RC 
network, and with age the C value decreases thus making the timing 
circuit run too fast.?? i.e.? not enough delay.

I already saw on Facebook.  Here's hoping I get my approval.  :)    Even
though I have no equipment yet.   But they don't know that.

The SVGA card for the P3 is excellent, not only can you put the display up
on the 'big screen', but the screen colors on it are much better than on
the little screen and you can make almost all of the screen into a
waterfall. I'm using a 24" monitor and about the only time I look at the P3
is when I am setting the ;Rev Lvl'.

On Elecraft's next improvement to the P3, a HDMI port would be nice...

Respectfully, is that really true?  The K3 needs to be shutdown via the 
Power switch due to some sort of shutdown procedure, (or internal

Yes! Like most equipment these days, the K3 needs to do an orderly shutdown under control of its processor to turn off safely and reliably. Like your P.C. you can pull power unexpectedly and it will often recover okay when power is reapplied, but you can also get corrupted data that forces a firmware reload - perhaps even using the forced MCU load procedure in the Owner's manual - as well as discovering that it turns on in an unexpected state or that it has "forgotten" certain parameters you set when it was last used.

 From the Fred Cady manual, page 33, Chapter 3?? "Elecraft recommends 
that you DO NOT turn your K3s off by turning off the external power 
supply.? Using the POWER switch allows the K3s to store variables such 
as the current VFO frequencies in EEPROM before shutting down.?? This 
might not happen if you turn the power off at the power supply.? You can 
turn the power supply off after the K3s shuts down".

Wow, thanks for the info!

I must have missed that in the manual...  I use the power switch, but I 
had no idea there was a power down sequence for the radio.

Is it an actual power down sequence, like in triggers shutdown code to 
run, or just some timing that has to happen in the right order?

73s and thanks,
Dave

Yes Dave, it is true. 
These days with most radios using some sort of microprocessor you should turn all brands off, not just Elecraft, using the power switch on the radio, not the switch on the power supply. This allows the processor inside the radio to save parameters etc. to memory and go through an orderly shutdown before it actually shuts power off to the radio. If you shut off the radio by turning it off using the power switch on the power supply the processor does not go through its orderly shutdown and you can scramble the processors brain. When you turn it on again you don't know what state it will power up in. If it powers up correctly, you were lucky.
Shut the radio off using its front panel switch first, then shut the power supply off.

Mark, WB9CIF

Respectfully, is that really true?  The K3 needs to be shutdown via the Power switch due to some sort of shutdown procedure, (or internal timings issue), within the radio?

I understand why, I was just not aware the K3 needed to be actually shut 
down explicitly.

I tend to never pull power from anything running anyway, (too many years 
doing PC, and dedicated hardware support in broadcast), but I was 
totally unaware the K3 needed a shutdown sequence...

In fact my shack desk has a dedicated 12 V power setup, which lives on 
the back of the desk, so I can't get to the switch without reaching 
behind the desk...

What a surprise!  I guess I need to re-read the manuals!  I missed that 
in both manuals!

73s and thanks,
Dave

Dave,

If you have *not* been "pulling the plug" to shut down the K3, then it 
may be that it needs a trip back to Watsonville to rezap the bootloader.

But OTOH if you have been turning the power supply off first and not 
using the K3 power button first, try 'doing it properly' over the 
weekend and contact support at elecraft.com Monday.

Removing the power from the K3 will not normally do any damage (but it 
can).  In most cases, the thing that happens is that it does not restore 
the band/frequency/mode, etc. that you were last using - or if you made 
menu setting changes, those will not be remembered.
Although it *can* scramble the bootloader, it seldom does - except if 
you are unlucky.

Yes, it is similar to a PC in that regard.

73,
Don W3FPR

Pete,

As mentioned by others, the K3(S) KEYOUT jack does not produce any 
voltage - the voltage must be produced by another source (sufficient to 
power the relay).

One method to check the K3 KEYOUT is to use your Ohmmeter.  stick the 
red probe into the center of the jack and the other probe to the shell.
It should read a very high resistance, even infinity (same as your 
ohmmeter reads with the probes attached to nothing) during receive, and 
then go to a very low value (close to zero ohms) during TUNE or Transmit.
If it does not do that, you may have a bad HEXFET driver for the KEYOUT 
line.

Related question:? Does KEY OUT essentially follow the TX state?? IAW, 
if PTT or VOX is asserted, it also asserts?? If so, I guess that means 
that it follows the keying when in QSK?? It's a real PITA to get to the 
back of my K3 right now or I'd check it myself.

Skip,

Yes, it does follow the keying when in QSK.  If it did not, the KPA500 
would not follow the K3(s) in QSK mode (the KPA500 connection uses the 
KEYOUT-LP from the ACC connector).
The T/R switching is all electronic and can be quite fast.

If the amplifier uses relay switching, the relay may not be able to 
follow the K3(S).

There is however an adjustable delay. Default 8 ms, which can be adjusted

Just like any other computer with volatile memory....? IF you don't tell 
the computer you are shutting down, it doesn't know and therefore 
doesn't have time to save the information to NON-volatile memory.

Anyone have a slick way of securing the KIO3B Audio I/O PCB
Assembly when installed so it doesn't wiggle up and down every time you

Drives me nuts and can't be good for longevity on the multi-pin connector.

I suspect that ?bad things? can happen if the power drops DURING the process of saving. Then you might get partial or invalid information stored. This could be why most of the time it is harmless.

Dick,

The K3 (note no hyphen in Elecraft model designations) can be powered 
off via the PS0 command.
To power it on, Pin 8 of the ACC connector can be pulled to ground.

Message-ID: <1c6dd04e-8fb8-ad17-6f23-271054513b89@comcast.net>

Thanks, everyone who responded to my earlier query - I now understand 
that the circuit in the K3 is equivalent to the old bipolar transistor 
switches we used to use for serial port CW/PTT keying.

So here's my problem - I have a small 12V DPDT relay that I want to use 
to switch the power to my SDR's preamp and active antenna - in other 
words, to cut them off when my K3 is in transmit.? What I can't figure 
out (be patient with a history major, please!) is how to use the Key Out 
jack to switch the power to the relay , while using the same 12V supply 
to power both the relay and the preamp/active antenna combo.

Ideally, the 12V relay would only be on when the K3's PTT was on.? The 
thing that's driving me nuts is that I had this working, once before, 
and then tore it apart for not very good reasons. Now I can't replicate 
what I had.

Would anyone be willing to go offline and help me figure this out?

Pete,

Connect one side of the relay coil to your +12 volt supply, and connect 
the other side to the KEYOUT jack.  Put a diode with the cathode 
connected to the +12 volt side across the relay coil.  The negative of 
your power supply has to connect to the shell of the KEYOUT connector.
The relay will be activated when the K3 KEYOUT is active - keying, TUNE 
and PTT will all activate it.

Yes, you should be able to use the same +12 volt supply to power the 
SDR's preamp and active antenna, but that is a different consideration 
than activating the relay.

73,
Don W3FPR

Nothing received from UTC, but they have until Oct. 15th to reply to 
me after which implied approval can be assumed.

Wed. I repaired my 43H by 122L inverted-L and yesterday got it 
re-installed with help from my prof. tower folks, so now it requires 
retuning from 495 to 475 KHz and installing new synth board and mod 
kit for the filter in my K3.  Probably another week or two until I 
can start calling on 630m with 5w EIRP.

That is what the RRC-1258 at the K3 does.? When it's all set up, turning 
on the K3/0 [or
K3 or K3s] will turn on the remote radio.? When the K3/0 is turned off, 
the remote K3 shuts down completely.

I have 2 KRC2's, one is working correctly with my K3. The second one

when powered up.? If I switch the OP/DL switch to DL the LED turns off.? 
I have no comms over the serial port with my computer.? I'm using the

I tried to D/L new firmware, but it never finishes and the symptoms

Any suggestions on what to try?

Interesting to read, Clay.
I just this month got the P3 Panadaptor and had problems at their
connections to the KIO3B.
I thought it was fixed when they sent me a new cable for the P3, but now it
is back on an intermittant basis and my connection to the computer USB has
gone, too.  I really do think it is within the daughter-board, but there is
nothing I can see there -- even looked for a cold solder joint through a
jeweler's loop.  Now I am really stuck...

You power off with the Pwr button K3/0 and it shuts down the remote radio. It turns On the remote with a short connection to a pin on the Accy 2 connector.

Good evening all,
I picked up a nice K1 yesterday at NearFest.  The bezel has the previous
owner/builder's name and call engraved in the bezel.  Does anyone have a
nice un-engraved bezel that they'd like to sell?
I figured I'd ask here before I try Elecraft.
Thanks,
Jon WS1K

Jon,

The best bet is Elecraft, p/n E100108 - Acrylic Display Bezel.  Contact 
sales at Elecraft 831-763-4211 to order.
If you want your own name and call (or anything else that you want) 
engraved on the bezel, contact Arkay Engraving (do it soon, Ken is 
retiring) http://www.arkayengravers.com/

Good Evening,
 ? After a cold, wet week the sun is out for the weekend.? High of 60 
today.? Too bad there are not more leafy trees up here because in the 
valleys they are reaching peak color.? I do have a few vine maple but 
the colder air is settling much lower down the mountain so they have yet 
to change.? More rain is due Tuesday but it would be better if it 
traveled a few hundred miles south.? The folks in California could use a 
month of rain.

The sun is blank as it has been for six days.? SFU is at 70 but we are 
getting auroras in the north.? I expect QSB of various types and some 
whistling, crackling, and hissing.? If it were easy it would not be as 
much fun.

Please join us tomorrow on:
 ?? 14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 ??? 7045 kHz at 0000z Monday (5 PM PDT Sunday)

 ??? 73,

Looking for suggestion about books or kits or whatever else that might interest a ten year old to electronics and to amateur radio.  He is adept at mechanical things and pretty bright.  What else could he be?  He?s my grandson.

But his understanding of electronics is well insulated by contemporary smart phones and games and the like, about the innards of which one can learn nothing in the old way ? the way we did it, by taking the family radio apart and then having to learn how to put it back together.

Any other grandpas or grandmas out there have experiences to share?

Thanks in advance,

That?s a good question.  Most kids? grandpas, even it they?re hams, don?t have a workbench filled with boat anchors torn down in some state of repair or restoration, or aren?t into home brew of much more than getting a relay to work, wiring a connector, or something similar.  They may not even know another ham that does any of that aside from screwing ?mysterious' black box radios together with preassembled cables, which is too bad in itself, but not the same topic.

Maybe something like this thing https://www.amazon.com/Elenco-Electronic-Playground-Learning-Center/dp/B0035XSZDI/ref=pd_sim_14_1?_encoding=UTF8&pd_rd_i=B0035XSZDI&pd_rd_r=NGPKH7KZXG9W97CMB6TD&pd_rd_w=VORMc&pd_rd_wg=Gq7yR&psc=1&refRID=NGPKH7KZXG9W97CMB6TD <https://www.amazon.com/Elenco-Electronic-Playground-Learning-Center/dp/B0035XSZDI/ref=pd_sim_14_1?_encoding=UTF8&pd_rd_i=B0035XSZDI&pd_rd_r=NGPKH7KZXG9W97CMB6TD&pd_rd_w=VORMc&pd_rd_wg=Gq7yR&psc=1&refRID=NGPKH7KZXG9W97CMB6TD>

Another option is a line of products called Snap Circuits (google it), which are pretty slick.  My 9 year old grand daughter has a couple of sets, and has done some interesting stuff with them.  Plus, they?re kind of fun ? :-)

Ted,

When my now-21 yr old son was about 14, he had by then earned his 
Technician and learned CW.  At that point he had an iPod and put an 
iambic keyer app on it.  He thought it would be fun to use as a key but 
I pointed out that that would be modulated CW and not actual CW.  Using 
his interest as an opportunity to teach some electronics, here's what we 
did:

1. Bought some equal valued resistors.  Then we could use series and 
parallel to get values needed.  A nice simple lesson there explaining 
why that is.

2. Bought a quad op amp chip.  This is harder to fully teach a kid, of 
course, but we wired up one as an inverting amplifier showing how the 
feedback resistor divided by the input resistor determines the scale factor.

3. We wired up another as a comparator using a potentiometer.

4. Used an NPN as a switch to key the rig.

In the end, ipod (now, smart phone!) audio goes to the amplifier.
Amp out goes to comparator whose output is triggered by cw audio in.
Comparator output goes to NPN switch to key rig.

And then you have the world's most high tech key.  :-)  We topped it off 
by having him solder together the circuit on perf board and mount it in, 
of course, an Altoids tin.  Maybe a mini project along these lines would 
work, tailored to suit his interests and age.

Good luck!
Mike ab3ap

I?d suggest anything under the Snap Circuits brand
https://www.amazon.com/gp/aw/d/B0002AHQWS/ref=mp_s_a_1_12?ie=UTF8&qid=1508086022&sr=8-12&pi=AC_SX236_SY340_QL65&keywords=snap+circuits

The kits are easy to manipulate, marked clearly (with proper symbols) and use real components. 

My kids love them

I second this.  My first foray into electronics in general and radio in
particular came from the old Radio Shack / Science Fair "160 in one" and
"200 in one" project kits.  Prepare for a spaghetti-wire mess of jumpers
between spring terminals, but it was a really great means for me to begin
to understand, and it was a great way for someone of that age (I think I
started toying with them around the age of 9) to experiment.

My favorite kit build, of course, was the AM Radio transmitter, which led
to a lot of experimentation with different antennas to see how far around
our neighborhood I could pick up my signal, trying to find "improvements"
to the circuit, means of using speaker and line-level inputs instead of the
microphone input so I could play music more easily, etc. etc.  It turned
out that, for reasons I didn't understand at the time, a 6-foot-long sheet
of aluminum foil makes a pretty good broadcast band antenna for a toy kit,
much better than just a wire :-)

Eventually this led to a postal mail conversation with my uncle, who is a
Ham, who in turn sent me a copy of "Tune in the World with Ham Radio" to
help answer some questions I had about antennas.  And then, upon doing the
calculations, I was dismayed to learn that a proper vertical antenna for
the frequency I was trying to use would need to be over 150 feet high, well
beyond the allowed length for a Part 15 transmitter.  Someone should have
told me about loading coils... I bet I could have gotten a little more
range out of that aluminum foil!

Hi All,
Decision made? now and I am going for the KX2 but now I have a question 
about the Batt Li-ion. The charger looks like it charges down the power 
lead and I am wondering how the balancing is done. Does the pack have 
its own balancing circuit or what.

Your foil antenna sounds a great deal like Marconi's first antenna used on the family estate to prove radio waves were not just "line-of-sight".

Some of us "homebrew" in software.

Then there is the whole "maker" community that should be a nice fit.

Companies like Elenco still make the 150-in-1 and 300-in-1 Electronic
Project Labs that let you easily walk through theory and application with
quick results yet still allow you to do the builds and easily modify
circuits. Safely. They have the "Snap Circuits" line of kits for things
like building an FM radio receiver. These kits are very simple to build but
show a result quickly. The labs are better for minds that are ready to
experiment and tinker, but the targeted kits may be a better introduction.
There are also a lot of Arduino kits with different sensors, inputs,
outputs, lights, switches, etc. that can make some fun projects quickly if
there is any interest in programming.

Tony,

The battery must be removed for charging.
The charger and battery are from the same manufacturer and I figure they 
have "done it right" whether that be a balancing circuit in the battery 
pack or some device in the charger.

Ted,

G3RJV - the Reverend George Dobbs has spent a lot of time and energy 
creating easy to build radios.  He has also done a lot with children to 
help their interest in building and radio.
His name is familiar to most QRPers and until last year has presented at 
FDIM - always quite interesting.

He has publish many articles and books, but one that may be of interest 
is available online at 
http://www.mds975.co.uk/Content/george_dobbs_trf_radio.html.

Inexpensive materials and easy to build are two things that George 
always adhered to.

Hi Don,
I am sure they have done it correctly but I have a number of different 
charges for li-po and other type batts so was just thinking of either 
not getting the charger or just providing another batt as it only seems 
to connect via 2wire connection for powering the rig.

Subject: [Elecraft] P3 not showing anything
Message-ID: <1508096992036-0.post@n2.nabble.com>

Today I went about upgrading my K3S with the KBPF3 board and a 6khz filter. 
I moved all my filters down one slot and put the 6khz filter in the first
slot. I installed the KBPF3 board, turned it on in the config etc.

I then went to the K3 utility and configured my filters, all seemed to go
well.

I turned the radio on after connecting all the cables and the pan adapter
does not show any signals. It is getting frequency information and changes
as I move the dial.

I have the cable connected into IF OUT on the radio and IF IN on the P3, and
I have tried both of the serial cables that came with the radio.

Connection to the computer works, the radio itself boots with no errors, but
nothing shows on the panadapter.  

See video attached for any help.

Thanks in advance for any help.

One possibility would be to get a 3-cell battery holder, and charge the 
cells independently.? A charger which charges several cells 
simultaneously, but independently, would assure balance.? Unless you use 
smaller cells, however, the will have to be external.

Tony,

Lithium Ion is a different chemistry than li-po.
I would choose to be safe rather than sorry and buy both the battery and 
charger.
If you are going to be operating portable over a long weekend, consider 
a 2nd battery.

Yes, it can be powered from an external power source through the 2.1mm 
coaxial jack.? For best results, the power supply should have a voltage 
of 13.8 volts or more - up to 15 volts is OK.
BTW - the internal battery can plug into that jack as well.

As I grow older with hearing loss I have become interested in the multitude
of digital modes that are available because they don't rely on good
hearing.  A bandwidth of up to 5 kHz is used by the popular WSJT-X
software.  Could the Elecraft radio software be changed so that K3/KSs
radios (equipped with the proper AM or FM filter) have a "WDATA" mode that
allows receiving and transmitting this 5 kHz bandwidth?  It would also be
nice too do the same thing for the KX3/KX2 but it might not be possible
after looking at the radio design.

Hi Bill,

Thanks for putting out the lat/long link. The best part for me was the
antipode link found on that web site. So much easier to figure out the
A/P rather than playing with DXAtlas to find.

As CX7TT, my A/P was in the Yellow Sea...draw line from Seoul to
Shanghai and that's where it was...explains why at greyline I could
always hear the JAs....

Now, as HP1XT, A/P is direct line from VK9 Xmas to VK9 Coco K and
slightly north...explains why YB is very easy from here....just SW of
Jakarta...

We read about greyline/SS/SR enhancement prop but would like to see

Scott,

The stock battery pack is sealed as one unit, not 3 individual cells.
Perhaps you are talking about a possible alternative battery supply and 
not the one sold by Elecraft.

Hi all,

Interesting OT thread. It's getting closed to the limit for OT threads, but
I'll risk another entry anyway. It reverberates with me since I just became
a grandfather. Of course I have another 10 years or so before I have to
really start thinking about this.

On G3RJV's book. It is very interesting, but dates back to 1972! All
semiconductors are germanium and Eurocentric to boot. I used the glass
encapsulated OC45 and OC71 as a teenager way back in Norway. I don't think
these were ever sold in NA. OC45 is an RF transistor (of sorts) and in his
final design it's used as both an RF amplifier and first stage AF amplifier.
He doesn't mention this in the text. The design is strikingly similar to the
one in my first spring terminal based trainer kit, probably around
1965-1970. On the OC transistors, they were glass encapsulated with a black
lacquer coating. One had to be very careful not to injure this coating as
they would become sensitive to light if you did. With lamp lighting you'd
get hum. Don't ask how I know this.

On the OPs question, for a 10 year old I think the "trainer" style kits
would be more appropriate as they come with all materials needed. The
posting prior to Don's had what appears to be a good suggestion, but Amazon
had only one left in stock last time I checked.

I'll try a completely different tack.

If you like the outdoors, how about Summits-on-the-Air (SOTA)? You'll get to spend time planning your SOTA adventure, and taking the hike to the peak.  He'll get to see you operating and hopefully that will encourage him to be interested as well. He can help you to build things like portable antennas and battery packs. If you get really adventurous one day adventures can turn into weekend camping.

My daughter is 3 years old. We have started her on short hikes and I hopeful next year she can do her first small peaks. Not sure how I'll keep her entertained on the summit but I'll cross that bridge when I get there.

Andy,

This may be a dumb question, but did you reconnect your antenna feed line?
I can't tell you how many times I've made that mistake. :-)

I did. In the video, it shows me receiving a CW signal. I can receive and
transmit fine on both of my antennas. I have been listening to the PA QSO
Party all afternoon as well. For whatever reason it still doesn't show any
signals on the P3.

Number of wives: 1.? Number of wives interested in ham radio: 0.? We 
have 4 kids, 11 grandkids, and 5 great grandkids [so far].? Number 
showing any interest in my ham radio: essentially zero.? Joe, at perhaps 
14, came in and asked what I was doing.? When I told him I was competing 
in a contest, he got a bit excited and his next question was, "How do 
you win?" His interest did not extend past that question.

A number of resources have been suggested [kits, projects, etc] but in 
my experience, those "work" only if they can tap into an interest area 
your grandson already has.? For example, a good friend has a now 14 yr 
old grandson who was somewhat immersed in Scouting, and really liked 
outdoors activities [hiking, camping, etc].? My friend ran into Summits 
on the Air when grandson was about 10.

Radio and SOTA added a new dimension to outdoor things and had the added 
advantage that he and his grandson could take advantage of shorter time 
periods than camping required to activate a summit. He bought a used 
FT-817 for grandson who now has a General.? Kids today carry the "Magic 
of Radio" around in the pockets of their cargo shorts, and a home-brewed 
station is exceedingly rare. Everything is pretty much just plug-N-play, 
like everything else in their lives.

Good luck, I hope you can find an avenue

NOTE I have also tried removing everything in-line and just having the
antenna, radio and P3 connected. 

I also tried removing the new board, but I did not try removing the 6khz
filter. This all worked fine before today.

Hi again,

Not a bad idea. We were very successful in getting our four children
interesting in the outdoors. The oldest daughter and her husband are even
into backpacking in the back country (Algonquin park), something we never
got into. The other three are very good hikers, too.

I hate to be a wet blanket, but I am not sure if I understand the joy of
activating peaks on ham radio. How do other hikers react to this? I know I
am extremely annoyed by people gabbing on their cell phones on the trail. Is
ham radio that much different?

Andy,

Do you have another receiver?  If so, connect it to the K3 IF OUT.  If 
you hear signals, then the K3 is working fine, look at the P3 for the 
problem.

OTOH, if you do not hear signals, review the work you have done - was a 
cable left unplugged inside the K3 or other "silly" stuff like that.

The IF takeoff is before the roofing filters, but the BPF3 is before the 
IF takeoff.  Check your work with the KBPF3 installation.

73,
Don W3FPR

Tested the cable and shield to shield, showed 0, pin to pin showed 0 and pin
to shield showed 1. 

The cable appears to be OK.

I got started in 1958 (almost 60 years ago).

There was no Internet, google, personal computers, or even hand 
calculators (unless you include the pencil).

I was not introduced by a mentor (elmer) or any ham.  It was some 
neighbor kids family table Zenith Ocean-O-Graphic radio.  I was 
twelve and visiting a couple friends and noticed the radio had 
several bands and one said "police".  I asked if they ever listened 
to the police on the radio; they hadn't. So I suggested giving it a 
try.  Well we heard no police at 5-MHz but after tuning lower 
encountered a lot of people talking (it was below 4-MHz).  I later 
found out that was ham radio.

I suppose there was some books at the community library (I was kinda 
strange as I frequented the library looking things up in the 
encyclopedia and reading magazines).  I was building model rockets 
with stuff from the hardware store at least a couple years before Sputnik.

As I said there were no local hams in our little farm community.  But 
sometime later I found out about an evening class on ham radio at a 
nearby town.  I got my dad to drive me there over several weeks and 
the teacher was a young HS music teacher who became my elmer giving 
me my Novice Exam.

I had listened late at night to AM stations from far away so guess 
that also contributed to my interest.  But I had to build my first 
radio from a kit (Knight kit Ocean Hopper).  I saved up allowance for 
half a year and did not even have any tools (my dad bought me a 
solder gun for my birthday).  He also bought my first transmitter 
(DX35) from my elmer who wanted to upgrade to a DX100.  My license 
arrive Nov. 11, 1958.
http://www.kl7uw.com/1958%20HamStation.jpg

I built my first antenna from TV twinlead (40m folded dipole).  After 
we moved to a larger community (2000) there was a TV shop so I 
frequented that (owner and one of the technicians were hams).

The rest was history "as they say".  There were $15 WWII surplus 
radios, old TV towers, more HB antenna, and Heathkit.  My CW key came 
by mail order from a store in Connecticut called the radio shack (way 
before the chain existed).

So many more ways to get started these days.  In the end its the 
kid's own curiosity and interest that will bring him into ham radio.

Hi Knut,

I've operated a couple SOTA's this year.

So far other hikers have been quite interested in what I was doing and 
didn't seemed to be annoyed, just curious in what I was doing.

Thanks Don, I decided to take a look again at the inside of the radio.
Re-seated all the cards and then took the bottom off. Guess what, that
single cable that attaches to the bottom of the board was disconnected,
probably from when I was putting the filter in.  I connected that up and
all is right with the world again.

Thanks for all the help and always remember to check that cable on the
bottom of the radio :)

One of the past speakers at Pacificon sold it at a private high school as
teaching how to talk to the ISS and satellites. Everything else came
following that hook.

To directly answer the question, the balancing circuitry is built into the battery for the KX2.  Typical for these types of enclosed batts.  The balancing device fits within the depression of the cells.

Tony,

The battery must be removed for charging.
The charger and battery are from the same manufacturer and I figure they have "done it right" whether that be a balancing circuit in the battery pack or some device in the charger.

Congratulations to your having found the cause.
I have experienced similar but from different cause, which was unstable connection inside the IF interface cable supplied with P3.
After replacing the coaxial cable with my home made one, my P3 started working perfectly again.

Don,
My replacement BFO crystals arrived today and I installed them. My BFO
range is now 5.66 kHz. FIXED! Thank you!

I have to add a note about what I call "Elecraft Mojo". The crystals were
back ordered so there was a delay before they could be shipped. The package
was sent Friday from California on its way to Florida. USPS web page said
that the package would deliver on Monday. I checked the tracking info this
morning (Sunday) and it said that the package was at the local sorting
facility. So, on track for a Monday delivery. I went out to the mailbox to
drop off an outgoing letter this afternoon and I was surprised to see a
Priority Mail box inside. Sure enough, it was my Elecraft parts order,
delivered by the USPS ON SUNDAY!!! To make sure I wasn't losing my mind I
checked the tracking info again and sure enough, it was sorted and
delivered today. I have NEVER received regular mail on a Sunday. Just more
of that Elecraft Mojo.

And, of course, my tiny little order was treated with the same urgency and
respect as when I bought the radio new. What a great company.

Now, off to finish the alignment!
Thanks again and 73
Mike M.

It sounds to me like the makerspace idea is pretty cool.  I may have to join one here in Bozeman cause project space (and projects) are seriously limited in the new digs.

Googling makerspace for Denver looks like there are number of places.  Maybe some would be better than others for your grandson.


Might be a good idea on 40m but I don't have a mobile antenna for that band.


Cheers,

Fred

Looking for suggestion about books or kits or whatever else that might interest a ten year old to electronics and to amateur radio.  He is adept at mechanical things and pretty bright.  What else could he be?  He?s my grandson.

But his understanding of electronics is well insulated by contemporary smart phones and games and the like, about the innards of which one can learn nothing in the old way ? the way we did it, by taking the family radio apart and then having to learn how to put it back together.

Any other grandpas or grandmas out there have experiences to share?

Thanks in advance,

Ted, KN1CBR

I'm with Fred.  I gave both of my grandsons a  Kano and they have just love
them <https://kano.me/>  .  This is, essentially, a  Raspberry Pi with a
custom-built Linux operating system <https://www.raspberrypi.org/>  .  

They've learned Scratch, a procedural-type of programming language that uses
building blocks to create the procedures.  They've also learned how to use
programming to make things go faster when playing  Minecraft
<https://minecraft.net/en-us/>  .  

The kids don't know they're learning process, procedure and logic but they
do.  When they're introduced to more formal programming, however, they'll be
well up the learning curve.  This is the introduction to the Maker movement
for them.  They've since been to a robot summer camp and they ate that up,
too.

Why do I suggest this first rather than take them up to a mountain top and
send morse code with them?  Its the hook.  Once they see how we merge
computers and the digital modes, I'm expecting the grandsons to have a
better sense of what I'm doing.  They see me doing things with a Raspberry
Pi and an Arduino with ham radio.  That's the bridge.

It is all about pulling them along, folks.

Cheers,

David/KG6IRW

The K3 has a 4.25 KHz hardware audio filter following the ADC.  Using
either the AM or FM filter, bandwidth can already be set to 4 KHz
(Shift=2.10, Width=4.00).

Folks,


Have a K3 (#8829) that has been spectacular to date with one exception.  Since first put together, about 10% of the time when powering up, the radio remains silent with the P3 flat lining.  All front panel lights and the main display come on as normal with no error messages displayed.   Turning the K3 off, waiting several seconds and turning back on restores normal operation with no other glitches/problems observed.


All software in both the K3 and P3 is current and both update without issue.   Unit is always shut down by the radio power switch and seems to work flawlessly otherwise.

Any others see this condition?

Message-ID: <CAFLbQccC+e=n0=+1+LJBmu=9AfQjgcG4A1KXge4-NFe-hGBUjQ@mail.gmail.com>

Since fixing my BFO range issue I started going through a full alignment. I
roughly set the BFO for all the filters. I noticed my frequency display was
off about 1500 Hz, so I re-set the 4MHz oscillator, then tried to run CAL
PLL. The CAL PLL started, but never finished. It just sat right around
12.1MHz.

I went back and tried the "PLL Reference Oscillator Range Test", which had
passed the first time I went through calibration. Now, it is "stuck" on
12.097MHz. What is strange is that it will jump briefly when I press Band+
and Band-, but it settles back to 12.097MHz.

I put a volt meter on pin 1 of U6 on the RF board to check the control
voltage. When I press Band- I can see the voltage briefly drop to near
zero. When I press Band+ it jumps to 7.5V or so, then goes back to the
original value.

If I rotate the VFO knob I can see the PLL frequency and the control
voltage vary over a range of about 5kHz on the VFO.

It seems that the PLL is moving with the control voltage, but the Band+ and
Band- keys during Cal FCTR don't seem to be doing what they should. Is it
possible that I fouled up another part of the calibration that is causing
this weird behavior? It sure feels like I'm doing something wrong, but I
can't figure it out.

I did a factory reset (hold 4,5,6 and power on), but I'm still seeing the
same issue with the PLL.

Any help will be greatly appreciated.

Thanks and 73

Yes, I meant separate batteries, NOT the Elecraft battery.  I should have made that clear. 

One possibility I've considered to reduce weight is a three cell battery holder for AA Li-ion batteries, good for about 800 mAh, as I have used with the KX1.  With the KX2, they would be good for about 2 hours of CW contest operation at 5W.

Hi everyone,

I've wrestled with this too.  My 9 year old son really enjoyed learning how to send his name perfectly in CW while being graded by the KX2's decoder.  He wouldn't stop until he got it perfect - no spaces or anything!  But my 11 year old gave up sorta quickly.  I drag them on SOTA activations and they quickly get bored at the summits, and they don't quite enjoy the hikes yet (less entertaining than video games).  Even the super tall ones.  I'd try a couple different aspects of the hobby and see which one sticks.  The Raspberry Pi idea is great, the CW thing took for one of my kids (could maybe sell it as a code you can talk in that nobody will know) but not really the other, contesting might grab an older competitive kid, and other kids might dig amateur radio satellites.  They're all different.  In the age of smart phones, Skype, and email, it can be hard to compete.  Skip's comment about getting friends interested too is pretty smart.

As far as other hikers during SOTA, I always try to operate out of the way with a small footprint (AlexLoop and KX2 with earphones).  I get more questions and probably do more good PR for ham radio than bad PR.  Lots of folks I meet while doing SOTA think it's interesting.  I usually mention how much power I'm using and which states/countries I reached.  Never had anyone complain.

Mike,

Record your current filter settings and other menu settings, and then do 
  a Master Reset (hold the 4, 5 and 6 buttons in while powering on).

There is a convenient form to record the menu settings in the K2 A to B 
instructions which you can download from the Elecraft website.

You may have to replace the firmware (to be determined later), but 
perhaps RF board U7 is not receiving as it should.  If you have a 
'scope, you should be able to see pulses on U7 pins 1, 2, and 3 as you 
rotate the VFO knob.  If all 3 pins show pulses, then most likely U7 is 
not working properly.  U7 pin 7 should move from 5 volts to zero volts 
in CAL FCTR when you tap the BAND+ and BAND- buttons.  If it does, then 
U7 is operating correctly.

Also make a quick check on the Thermistor board - a quick check is to 
measure the voltage at U5 pin 5 - it should be 4 volts or 1/2 the 8 volt 
supply.  If not, check the Thermistor board for solder bridges.  You can 
see the back of the Thermistor board if you remove the Control Board and 
Front Panel.

Doug,

The computer will "exercise" the serial port lines when it goes through 
its startup diagnostics.
So if you have the K3 PTT-KEY menu set to anything other than OFF-OFF, 
it will key the K3 momentarily.

If you are not using the PTT-KEY function, then turn it off.  If you are 
using it, the only solution is to either power the computer before the 
K3 or put the K3 into TX TEST before powering the computer.

That works but WSJT i.e. can't find the KIO3B com port in my setup when 
the K3 is off while powering the computer first. Although the com port 
is listed in the device manager. Kinda strange... (Win7 Pro).
That happens both on my desktop and on my notebook.

This is usually caused by windows searching for a serial mouse on 
startup.  See the link below to disable this.
This applies to Win 10 also!

If the K3 is in CW mode, the computer may key the rig, but there is no 
RF output (unless you hold the key down.)? No harm, no foul.

Yes and it also allows you to store messages that can be sent via one or two
keystrokes.  See the memory section of the manual.  It will also add
sequential serial numbers to contest responses.  There are several wireless
USB keyboards that work well with the PX3.

Hi Knut,

On the contrary, I find most people are actually pretty interested in what you're doing, and even in this age of global reach via phone/internet often quite impressed by what communications can be achieved with a little radio (in my case a KX3) and a wire antenna.  In fact, I've gone so far as flying a SOTA flag off my crappie pole when I'm operating encouraging folks to come over a ask what I'm doing.

Hi again,

Not a bad idea. We were very successful in getting our four children
interesting in the outdoors. The oldest daughter and her husband are even
into backpacking in the back country (Algonquin park), something we never
got into. The other three are very good hikers, too.

I hate to be a wet blanket, but I am not sure if I understand the joy of
activating peaks on ham radio. How do other hikers react to this? I know I
am extremely annoyed by people gabbing on their cell phones on the trail. Is
ham radio that much different?

Message-ID: <E0216CDF-D600-4A24-AC8F-1F750A922A94@arrl.net>

I just went through the amplitude and phase adjustment to null out the opposite sideband response.  All went well.  I started the PX3 Utility and tried to save the configuration settings, per the suggestion in the manual.

About half way into the process (Green Bar about 50%) I get an error message that says:

?No Response To Read EEPROM Block?.

After I X off the block, the Green bar just sits there. It doesn?t appear to be advancing so I cancel.  Evidently, I cannot save the configuration.

I don?t see anything in the manual about this.  Dies anyone know anything about this?

Dave,

Try it several more times to see if that error is just a 'glitch' or if 
it is a hard error.

If A hard error, contact support at elecraft.com and see if they might have 
any answers.

Hi Knut,

On the contrary, I find most people are actually pretty interested in what you're doing, and even in this age of global reach via phone/internet often quite impressed by what communications can be achieved with a little radio (in my case a KX3) and a wire antenna. In fact, I've gone so far as flying a SOTA flag off my crappie pole when I'm operating encouraging folks to come over a ask what I'm doing.

Thanks again Don. This was an interesting one.

The DAC was constantly receiving data/clock signals from the CPU, even with
all the controls at rest. You could see the DAC output voltage jump when
the Band+ or Band- keys were pressed while in CAL FCTR, but then went
immediately back to where it started. I was stumped.

A little "googling" turned up an old post from 2004 by John G3NYX who had
the same problem while building his K2. Someone suggested to him to move
the RIT control and try again. Now, I confirmed that my RIT wasn't on so I
figured that it would have nothing to do with this issue. I was wrong. I
twisted the RIT knob a few times back and forth and then retested the PLL
range. Now everything works! It seems that even with RIT off, the CPU still
sends data to the DAC because of RIT. If the RIT control was a little noisy
and was right in between two readings it would cause the CPU to constantly
update the PLL reference oscillator DAC.

CAL PLL worked great, the BFO adjustments are done and the radio is working
great now.
Thanks for your help Don!

There was an issue with saving and recalling the configuration and memory
settings with the PX3 but I do not recall ever seeing a firmware update to
fix.  The issue was during the last update, there was an oversight.  The
file name for file was changed in one section of the code, but not in
another causing an error.  This was some time ago so I will have to go back
and look at my solution. But it essentially meant that you saved the file
under the new naming convention, then had to change the name to the old
convention and you could recall it.

Good Morning Bob,

I?m not sure my problem is the same as yours.  My PX3 is only 2 years old and I had never saved a configuration file to this point.  Neither had I adjusted the amplitude and phase on the I and Q channels.  I did that for the first time last night and, seeing it was recommended procedure, attempted to save the configuration.  That is when I had the problem.

When the support folks at Elecraft have had their morning coffee, I will call and see what they have to say.

Thanks for thinking along with me.

73,

Dave, K4TO

Because I didn't notice anyone mentioning it, I will point to the
manual's
description of the menu entry
CONFIG: CW WGHT
where it says
"Tap 4 to select VOX NOR (default) or AUTO OFF.  The AUTO OFF setting
turns CW vox off on power-up, avoiding accidental keying by attached
PCs, etc."

The AUTO OFF setting has prevented many problems for me.  YMMV.

Thinking of upgrading to the K3S and adding the 2M option.  Two questions:
1.  Will the module operate outside the standard frequency ranges with the
MARS mod?
2.  Do I need to add the FM filter?
Thanks,

Barthold,

The band does not matter, you need the 13kHz roofing filter to run FM on 
any band.

Hi Dave, 

I sent you an email, please check your inbox.   The problem you're
describing sounds a lot like an issue we had with a few early PX3's and the
on-board EEPROM.   

73, 

Paul

For those that asked, my SOTA pole is a KWIK STIX Bream Pole by South 
Bend Sporting Model KS-2-20 6 section, reduced in length from 20'6" to 
18'3".? I'm not sure this is made any more, but they do still offer a 5 
section 17ft variant.

I use it to support a LNR EFT-10/20/40 EndFedz Antenna Trail-Friendly, 
or very occasionally a 40/20/15/10m homemade linked dipole.

Check? out B&M crappie poles also. They have a great 20' Black Widow that I have and it works fine as either a vertical or support for a end fed.

Subject: [Elecraft] PX3 configuration save problem
Message-ID: <E50C1523-A91F-4C1A-8252-6C452A9333BE@arrl.net>

I am happy to announce that my PX3 now saves the configuration without complaint.  Paul, N6HZ, project manager for the PX3 contacted me with instructions.  I took the PX3 apart, photographed the main board and emailed him a copy.  He looked it over and said all the correct parts were in the correct places, so there must be an EEProM problem.  I should send it back.

So I put it all back together so I could ship it.  Then I thought perhaps I?d better see if it still works or did I mess something up.  It worked.  So then I thought maybe I better try to save the configuration.  I fired up the PX3 utility and it saved the configuration without a hiccup.

So, mission accomplished.  The amazing, pro-active response of the Elecraft support team has done it again.  Other businesses should take note and do likewise!!

Thanks to all who offered help.

Here is one more approach:

I took a pine 1X2 and cut it into 3? pieces ; then screwed a couple of Fahnstock clips into the
tops of each one near the ends. I then selected an assortment of 2 node components plus a
pile of 6? cut copper wire pieces.
Whoopee?we could then make stuff?doorbell plus switch, simple diode rcvr, then one with a
single transistor audio amp plus speaker (needs 3 NODE block), morse code key and buzzer
etc etc
Tiny stuff can be intimidating?so the blocks fit his way of playing and we were off and running.
A regen rcvr on a board for 40M can be a jump step and its all fun.

I started with a flyer from Summer school that showed how to make a crystal set.? Simple stuff, took a week or so to gather the materials and wire it all up with a wood burning converted soldering iron, hi.? We did it on a bread board that Mom said was too marked up.? Used a telephone hand held receiver, a cold water ground and a wire somewhere in the trees, and WE HAD AUDIO.? We could hear the AM stations quite well.? Then came the Regen receiver out of 1940's Popular Mechanic article.? We had CW.......... Thats all it took for this ten year old in 1948.........I was hooked......

Excellent idea Alan!

An added advantage of that kind of approach is that you can write on the 
blocks - like the name of the component, its schematic symbol, and he 
can see how to follow the schematic to connect them.  Polarized devices 
like diodes can be marked with the anode and cathode ends and 
transistors can be marked with base, collector and emitter and the 
difference between an NPN and a PNP can be clearly indicated.
Should make learning much easier for him and he will likely retain it 
better.

Steps after that would be teaching the resistor color code and learning 
how to read the values on capacitors - capacitor values are not trivial 
these days.

Then an introduction to data sheets.  By the time he is a couple years 
older he will know more about circuits than many modern hams.

YAW!

Children learn by playing. If You let him play with Your radio by 
teaching him (her?) where he can listen the ham-traffic. Make sure to 
tell him what not to touch: they are surely so sly, that they try it 
anyway, not depending "what A nice kid".

Don't ever, ever, ever and never tell him about learning by internet, 
it's too far from our hobby and he'll learn that way in any case.

Find out what branch in this hobby makes him most intrested and give him 
your full support. Try to spot other ham-radio-interested kids near the 
same group of ages. Avoid giving more advise than he (they) ask for.

Kids in age mentioned are smart. Let them freedom to try anything. Only 
control should be that they dont hurt themselves, others or cause 
exessive trouble or harm. This control is good to be kept so that they 
don't know they are monitored.

He wouldn't stop until he got it perfect - no spaces or anything!  But my 11 year old gave up sorta quickly.  I drag them on SOTA activations and they quickly get bored at the summits, and they don't quite enjoy the hikes yet (less entertaining than video games).  Even the super tall ones.  I'd try a couple different aspects of the hobby and see which one sticks.  The Raspberry Pi idea is great, the CW thing took for one of my kids (could maybe sell it as a code you can talk in that nobody will know) but not really the other, contesting might grab an older competitive kid, and other kids might dig amateur radio satellites.  They're all different.  In the age of smart phones, Skype, and email, it can be hard to compete.  Skip's comment about getting friends interested too is pretty smart.

> As far as other hikers during SOTA, I always try to operate out of the way with a small footprint (AlexLoop and KX2 with earphones).  I get more questions and probably do more good PR for ham radio than bad PR.  Lots of folks I meet while doing SOTA think it's interesting.  I usually mention how much power I'm using and which states/countries I reached.  Never had anyone complain.

Subject: [Elecraft] Suggestions for Introducing a 10-year-old to Amateur
 Radio and Electronics
In-Reply-To: <5D7805B2-7444-4FDB-A919-E95F2E1DA901@yahoo.com>

After a period of experimenting with basic circuits, a good step is to 
find an older copy of the ARRL Handbook.  I studied the "Electrical Laws 
and Circuits" section of the handbook until I had a good understanding 
of what the components did.

That is the source I learned from at the age of 15.  By the time I 
graduated from high school, I was designing my own elementary 
transmitters and receivers.  Then I went to college and learned the 
theory behind what made it work - so I sort of "did it backward" from 
many engineers.  I know "how it worked" first, and then I learned "why".
It gave me a lot of practical experience that aided me tremendously 
throughout my career.

10 may a bit too young for that, and that content is a bit better 
introduced when the student has some grasp of math - at least enough for 
parallel and series resistors, capacitors, and inductors - so he should 
be familiar with at least fractions, multiplication and division.  Once 
he comes to the realization that the fraction bar indicates division, he 
should be ready for those kind of calculations.

I am talking of analog stuff here.  Digital is a whole other world, 
although voltage levels and current drawn by devices are in the 
never-never- land between digital and analog.  TTL and CMOS devices in 
DIP format are still available, and simple gates are essential starting 
points for understanding digital operation at the circuit level.

Hello,
I'm looking for a KFL1-2 K1 2 Band Filter Module. I'm mainly interested in
80 meters and do not care what the second band is.
Thanks!

The world isn't the same as when we were all 15.

I think what you have to do is find out what excites the kid, and then 
finding a part of amateur radio that matches.

I'm far from 15, but I never got to love CW, even though I made more 
than a few contacts when I had my novice license.

Gotta say SSB isn't that interesting either.

Always liked digital modes, but I think it'd be hard to get the 
texting-generation interested in something that's far more universal in 
the age of social media.

The ideas are great, but the first step in solving a problem is defining 
it.  Want a specific kid involved, find out what they like, what tickles 
their curiosity.

Unfortunately you are not going to find many companies that are more
responsive or more accessible than the folks at Elecraft. The key to their
unique success is great products with excellent service.

Message-ID: <93960537-22ca-6b47-a78e-7271d90b2492@horizon.co.fk>

Hi,

After nine years the dreaded "ERR 12V" struck. Possibly brought about by 
my increasing use of high duty cycle RTTY and FT8. Normally I'm S&P so 
the high current pins don't usually see much heating time.

The whole job on #00345 took about three hours of patient progress, 
dismantle, repair and rebuild. Interestingly only the pins on the RF 
board were toasted and not those on the PA module which looked as good 
as new. I ended up replacing the two sets of six pins, one set a clear 
necessity and one set precautionary and one damaged female connector.

The most annoying thing about the whole job were the TMP coax connectors.

Regards,

Mike VP8NO

Don,

There is no selection of a "group of bands" - but you can select the 
proper antenna for any one band.  Once you have done that, change bands 
and select the desired antenna for that band.  When you have covered all 
bands of interest and selected the antennas for each, is the proper 
antenna selected when you switch to that band?  If so, all should be well.

Did I misunderstand something in your question?

The band does not matter, you need the 13kHz roofing filter to run FM on any band.

 > Is there some adjustment I?m missing?

Try adjusting the center frequency (shift) or decreasing the Low Cut
(FL) and High Cut (FH) by similar amounts.  In general, the important
spectrum for speech is 400 - 2200 Hz while simply "dialing down" the
width causes the Low Cut to raise too quickly.

The K3/K3S nominal 2.8 KHz bandwidth is set at 100 - 2900 (FC = 1500).
Simply dialing the width down to 1.8 KHz results in a passband of
600 - 2400 Hz (FC remains 1500 Hz).  Adjusting FC down to 1250 or 1300
Hz will greatly improve the "clarity" of SSB.

In addition, the K3 has a flat audio response while most rigs have a
slight raising characteristic (about 3 dB/octave).  You can emulate
that response using the RX EQ.  Set 0.05 = -16, 0.10= -16, 0.20= -6,
0.40= 0, 0.80= +3, 1.60= +6, 2.40= +8, 3.20= +9 and the audio will
emulate "other rigs".  You can also set 3.20 to -6 to minimize high
frequency noise.

I generally agree with Joe's advice, but will differ here.? Joe is right 
that full bandwidth (with the 2.7 or 2.8 kHz filter) is 2.8 kHz, but 
optimum spectrum for speech intelligibility with this bandwidth limit is 
400 Hz to 3.2 kHz. This is fundamental stuff -- Bell Labs, probably the 
premier engineering institution on the planet back then, figured it out 
at least 100 years ago, and lots of research in the years since has 
confirmed it.

I own 1.8 kHz roofing filters, but find them too narrow for my 
ear-brain. We're all different, so YMMV. I have a 2.1 kHz filter in one 
of my K3s, and like it. I rarely set my IF narrower than 2 kHz for SSB.

As Joe has noted, RXEQ can be adjusted to tilt the response a bit. If 
like many of us old guys you have much hearing loss, you might want to 
boost the top octave band in RXEQ by 3 dB.

There are two other issues at play here. First, the K3 has a pretty good 
but pretty small speaker. Second, chief engineer Wayne Burdick has 
strong roots in backpacking, so his audio stages tend to be a bit 
current starved.

Joe and Jim, thanks for the equalization advice. I'm mostly a CW op, so I'd
assume raising the 400-500 Hz range and suppressing the higher frequencies
would help. I'll tinker with it.

However, the K3 defaults to 100 - 2900 Hz as I pointed out.

It would be handy if SSB defaulted to FL=0.40 (or FL=0.30) instead of
FC=1.50 as that would avoid the need to adjust FC when "dialing in" a
narrow filer.  Most of the older generation of rigs set the carrier
offset (i.e., FL) when selecting filters rather than center frequency.

With typical filter widths, there is no real value to RX EQ on CW.  I
tend to leave 0.40 and 0.80 flat and set 0.05, 0.10, 2.40, 3.20 to
-16.  0.20 and 1.60 are either flat or a slight (-3) roll off.

The nice thing about the K3 is that it will store separate RX EQ for
CW and SSB so setting one will not mess up the other mode.

Ummm ... by all means tinker with it.? We are all different.? My hearing 
is pretty well shot, SSB in a contest or DX pile is a non-starter and I 
stay on CW most of the time.? It peaks about 600 Hz, which is my pitch 
frequency, and I've tried surrounding it with RX EQ settings to enhance 
it.? I may be doing something wrong here [that has occasionally happened 
before], but it doesn't seem to work well.? The APF does, it is touchy 
to get set up, and I only use it occasionally, but the RX EQ that looks 
like the response of my hearing aids seems to work best, regardless of 
my DSP BW/HI-LO CUT settings.? YMMV and probably will.

Are you using the WIDTH and SHIFT on SSB?
I would suggest that you will find better success using HI CUT and LO 
CUT for SSB.
The voice audio needs some information in the 300 to 400 Hz region for 
clarity, so the LO CUT must be set in the 200 to 400 Hz range to keep 
intelligibility.
The HI CUT can be reduced to as much as 1500 Hz and still maintain 
intelligibility, but at such extremes, the characteristics of the voice 
will be lost.  It is best if the HI CUT is placed at 2800 for good 
recognition of the voice.  Reduce that frequency if there is 
interference (QRM) on the high frequency side.

I disagree. Audio below about 400 Hz makes VERY little contribution to 
speech intelligibility. The 1 kHz, 2 kHz, and 4 kHz octave bands are 
where the action is. Sound below 400 Hz provides "body" to the voice and 
"thickens" it. It can more pleasing to listen to, but it also burns 
transmitter power. So if the goal is communications, power is better 
devoted to those higher bands.

Once again the good/bad/indifferent K3 audio surfaces. I do not get it - 
never have. The K3 is so audio customizable that it should be pleasing 
to nearly every user (I say nearly, as there are some whom will never be 
happy). To make a long story short, here is link to my current settings. 
Of course, they are my settings and may not please everyone.

****

**The following are the settings I am /_currently_/ using on 40, 75, 160 
for armchair copy (meaning very reduced hiss, no ANF warbling, and 
pleasing listening). My RX audio goes through amplified Behringer studio 
speakers with bass/treble adjustments.
**

**

Note: I often make RX Eq changes depending upon mood, attitude, boredom, 
and allergies/colds - as needed.

The speaker adjustments:? bass and treble both set to the middle notch

K3 settings:

 ?(Config Menu):
 ??? AGC DCY -??? NORM
 ??? AGC HLD - ? 0
 ??? AGC PLS -??? NORM
 ??? AGC SLP -??? 4 to 6 (low setting reduces artifacts from the 
Automatic Notch Filter)
 ??? AGC THR -?? 12
 ??? AGC F -????? ? 120
 ??? AGC S -???? ?? 20
 ??? Shift -????????? 1.25
 ??? Width -??????? 2.7

Be sure to read the "Noisy K3" section on http://www.w3fpr.com/ - 
excellent information!

The disclaimer:? Your mileage for the above settings may (will) vary - 
depending upon speaker selection, personal preferences, and your hearing 
acuity.

Note:? I made all of my settings by hand, using the K3 menus - thus 
affording instant gratification. I used to do all the EQ stuff with 
outboard devices. With the advent of my K3, all those devices took a 
one-way ride to a hamfest.

This places the lower cutoff at DC!  It is very wasteful and susceptible
to significant hum/buzz.  Far better to use FL=0.30 and FH=3.00 for a
bandwidth of 3 KHz and reduce FH as needed based on QRM.

Wayne and Lyle have repeatedly warned against using excessive boost in
RXEQ.  One would be far better to reduce all values by 10 to 12 dB as
this will help prevent over driving the audio amplifiers, etc.

This has the same characteristic without the issues of over driving the
audio amplifier.

       RX EQ           1        -16
                       2        -12
                       3        -3
                       4         0

I?ll be speaking at Pacificon's antenna symposium tomorrow (Friday, Oct. 20th). My presentation, from 3:30 to 4:30 PM, is on antennas for ultra-portable HF operation. This talk was a late addition, a previous speaker having dropped out.

If you?re interested in attending the symposium, check the website (pacificon.org). Tickets must be purchase in advance.

As part of my talk I?ll be discussing a new portable antenna, the Elecraft AX1, designed specifically for the KX2 and KX3. We?ll also be showing the prototype at our booth.

We?re not taking orders for the AX1 yet, so please don?t call Elecraft Hq about it :)  That said, I?ll be happy to send out an early draft of the FAQ on request. Please email me directly.

Message-ID: <86067DCE-229D-4DB0-BD87-31934E0BFF83@elecraft.com>

Thanks for all the inquiries so far regarding the AX1. I think I?ve revised the FAQ five times this morning :)


> Question:  Weight?  Or, Weight as a percentage of KX2/KX3?

4.0 ounces (total for base unit + whip).


> Question:  is the BNC connector on the KX2/KX3 safe from damage from torgue applied by the whip antenna?

Yes. The BNC connectors on both the KX2 and KX3 are bulkhead-mount types, not PCB-mount.

I will amplify Jim's and Wayne's and Lyle's comment regarding audio, 
attenuation of a frequency or frequencies produces far superior results 
to boosting a given frequency or frequencies.?? We have become 
accustomed to "boost this" and "boost that" when in fact attenuate this 
and attenuate that is the better option.?? One just has to understand 
the spectral components of audio to figure out how "this and that" applies.

Looking forward to it!? And I'm the first speaker after lunch, talking 
about a compact, easy to build receive antenna for the low bands, 
especially 160M.? And if you can't make it on Friday, I'm scheduled for 
the same talk before lunch on Saturday.

The Samuel F. Morse Amateur Radio Club, a Sacramento, California based 
CW enthusiast club wanted a special time to bring bug operators together 
on the air. In the same spirit as ARRL's Straight Key Night, 
participants are encouraged to make simple, conversational, 
?chewing-the-fat? QSOs using their bug type key. This is an opportunity 
to exercise, share and exhibit your personalized fist. This is NOT a 
contest. However, there is a very easy and quick required signup form 
found at https://w6sfm.com/bug-roundup/. Once you are registered for the 
event simply Call "CQ BR" so folks know you are a Bug Roundup 
Participant.? So lets grab that bug, clean those contacts, and let?er 
fly! We want to hear that ?Banana Boat / Lake Erie Swing" or that 
commercial KPH/WCC quality fist.

Reserve the date! The event begins on Friday November 17th (00:00 UTC) 
and concludes Sunday Nov. 19th (23:59 UTC), 2017
That's 4:00 PM Friday evening until? 3:59 PM Pacific Time (LOCAL)

For more information, to register your station, and to help assist in 
spotting, potentially increasing QSOs, an On-line chat window link can 
be found near the bottom of Bug Roundup home page located at 
https://w6sfm.com/bug-roundup/ We hope to hear you all on the air! 73,

Thanks, Don. No, you didn't misunderstand my question. I was trying to
select the antenna first, then select one or more bands second, which
doesn't work. Your way was to do it the other way around; select the band
first, then select one or more antennas second, which does work. All better.
Thanks again and 73!

Don,

I think there may have been a software utility in the past which allowed 
you to do something like you were trying, but I may be thinking of the 
KRC2 utility instead.

I am glad to hear that you are working OK now.

I?ll be speaking at Pacificon's antenna symposium tomorrow (Friday, Oct. 20th). My presentation, from 3:30 to 4:30 PM, is on antennas for ultra-portable HF operation. This talk was a late addition, a previous speaker having dropped out.

If you?re interested in attending the symposium, check the website (pacificon.org). Tickets must be purchase in advance.

As part of my talk I?ll be discussing a new portable antenna, the Elecraft AX1, designed specifically for the KX2 and KX3. We?ll also be showing the prototype at our booth.

We?re not taking orders for the AX1 yet, so please don?t call Elecraft Hq about it :)  That said, I?ll be happy to send out an early draft of the FAQ on request. Please email me directly.

73,

They are all <2 years old, being (iirc) announced in 2015 and shipping
in 2016. Maybe < 1.5 years.

I was really happy they released the K3S. It allowed me to pick up a
used K3, upgrade it, and save some money.

Don -
I had exactly the same problem and got it going a couple of days ago,
thanks to help from W4TV on the microHAM list.
The 'magic' setting that got things going for me was to go into the K3 Main
Menu, while the radio was in the DATA A mode, and find MIC SEL and set it
to LINE IN.
Then exit the menu and set the front panel MIC GAIN so you have 4 bars
solid, and the 5th bar blinking on the ALC meter. I did that by putting the
K3 in the TEST mode, so I would not be putting out any RF, and then clicked
on the TUNE tab in WSJT-X.
I hope that gets you going. I am no expert, but that is what made it work
for me. Shortly after doing that I made my first FT8 QSO.
Best of luck and very 73 de Dave - K9FN

Don,

How do you have the soundcard connected to the K3?  What soundcard are 
you using?
Are you using the Line In jack on the back of the K3?
If so, do you have MIC SEL set to LINE in Data A mode?

You might plug the cable you have connected to K3 LINE IN to an audio 
amplifier or computer speakers to see if you can hear the soundcard output.

If you have upgraded the K3 with the KIO3B and are using its internal 
soundcard, you must have nothing plugged into the LINE IN jack.

For setting the K3 audio level, you may want to read the instructions on 
my website www.w3fpr.com - scroll down to the bottom of the left column 
and click on the link.

73,
Don W3FPR

Subject: [Elecraft] More macro storage
Message-ID: <006c01d349bb$f4fe60e0$defb22a0$@net>

Hi all,
I have a bit of a dilemma when it comes to macros and my K3s. I own a kPod
that's fully loaded with 16 always-used functions. I just developed two more
that I will use on a very regular basis, but I have no way to command them
into the radio now. The RS-232 port on the P3 is needed to connect to a
MicroHam MicroKeyer-II full-time, so the only time I can connect the K3s/P3
to the computer directly is when I remove the CAT connection from the serial
port.

My understanding is that Transceiver macro memories mirror kPod commands,
and if that's the case, I'm not sure what I can do to fire off these two
macros (one does a series of actions, the other undoes them). These macros
are for listening to the pileup on VFO-A while locking the DX on VFO-B, and
switching the L-Mix-R values for this format (then back again with the
un-set macro). Any ideas?

John,
The order date of my K3S serial #10629 is January 28, 2016. So, I'm guessing
your 105xx order date would be, depending on early 5xx or late 5xx, December
2015 or January 2016.
Be aware John that the early K3Ss, lower than serial # approximately 10700
or 10800 (I don't remember the exact serial #) need some modifications to be
up to current K3S production.
The mods are the IMD mod for the K3LPA and KPA3A, the fan mod and the KPOD
mod so the KPOD can be powered from the front panel KPOD jack.
I just got my K3S back from Elecraft about two weeks ago after having these
mods installed.
I believe Elecraft will perform these mods for free except for shipping to
and from Elecraft.
If I'm incorrect on that I'm sure Don or someone on the reflector will chime
in.

Data A is absolutely the correct mode for JT65 & 8. You don't want any comp or TX EQ you have with sideband.

Hi Peter,

The KPod doesn't actually store any macros.  It basically gives you 16 programmable function keys in addition to the 10 available on the front panel of the K3s.  The only macros it can activate are the 16 that you can store in the K3s using the K3 Utility.

One way to add more is to use the SVGA option of the P3.  That will give you up to 50 messages/macros but they must be activated from a USB keyboard plugged into the P3 (not the P3's RS232 port, though).

If you don't like the idea of another keyboard, check out NK7Z addition of a Genovation keypad (www.nk7z.net<http://www.nk7z.net>).   www.QRPWorks.com has its SideKar that can store messages/macros externally but it needs to use the serial port.


Cheers,

Fred KE7X

Not true.  One should use DATA A which transmits as USB but disables the
compression and TX EQ.

 > Data modes on k3 are setup for rtty

DATA A is correct for FT8/JT65/JT9 as well as PSK31/PSK63/PSK125 and any
other audio (subcarrier) based data modes.

AFSK A is the correct mode for AFSK based RTTY as it transmits LSB and
includes an audio filter centered on the mark/space tones to clean up
any hum/noise/clipping/etc. from the sound card or due to over driving
the audio input.

The secret to using DATA A and AFSK A is to connect the sound card to
the "LINE IN".  Select DATA mode and then use MENU:MIC SEL = LINE IN.
Once you have selected LINE IN (*NOT BEFORE*) adjust MIC GAIN for
four bars of "ALC" with the fifth bar flickering.  You *CAN NOT* set
mic gain in SSB or with MENU:MIC+LIN=ON because the mic gain will
adjust the mic input (front or back) and not the LINE input.

Robert,

There are 4 data submodes in the K3.  DATA A is for soundcard digital 
and is the default sideband same as USB except that compression is 
turned off and any Equalizer settings you might have for SSB are set to 
flat.

AFSK A is specifically set with defaults for RTTY from a soundcard - 
default sidenamd is LSB.

PSK D (direct) can be used for PSK31 or PSK63 if you use the KY commands 
to send ASCII to the K3 or you can key from the paddles with CW and they 
will be sent as PSK.

FSK D is similar to PSK D, but you can also use the FSK IN pin in the 
ACC connector to send FSK driven RTTY.

Mark,

I don't believe those mods will be done for free, but there may be a 
special pricing on them if that is all the work to be done.
If you have other repair work done on your K3S, they will be installed 
as part of that process.

Hi Robert,
Data A does use USB which is normal for all digital modes except RTTY. For
RTTY you should use AFSK A which is LSB. Of course, there is also FSK D for
transmitting RTTY.

As Wayne N6KR mentioned yesterday,

"I?ll be speaking at Pacificon's antenna symposium tomorrow (Friday, Oct.
20th). My presentation, from 3:30 to 4:30 PM, is on antennas for
ultra-portable HF operation. This talk was a late addition, a previous
speaker having dropped out.

If you?re interested in attending the symposium, check the website (
pacificon.org). Tickets must be purchase in advance.

As part of my talk I?ll be discussing a new portable antenna, the Elecraft
AX1, designed specifically for the KX2 and KX3. We?ll also be showing the
prototype at our booth.

We?re not taking orders for the AX1 yet, so please don?t call Elecraft Hq
about it :)  That said, I?ll be happy to send out an early draft of the FAQ
on request. Please email me directly.

Wayne

John,
I was informed here on the reflector. I think it was Wayne that sent the
e-mail describing the mods. It is also on the website in the K3/K3S mods
section.
Here are the mods and I think this will answer Bob's, K4TAX question as
well.
The repair report says the following:
IMD improvement KLPA to rev B3, KPA3A to Rev C9.
KPAIO3MDKT (This adds a capacitor to the KPA3A I/O board to reduce fan noise
on transmit)
KPOD Ready, FP R82 to 6.8 Ohm, R60, 66, and 75 to current values. 7T
capacitor. This provides power to the KPOD directly from the front panel
jack for the KPOD. Early versions of the K3S below approximate serial #
10700-10800 require the KPOD to be powered from the K3S 12 Volt accessory
socket on the back of the radio or powered from an external power supply or
wallwart.
John, if you or Bob, K4TAX have any other questions, let me know and I will
try and answer them.
If I have missed something or have something incorrect, I'm sure Don or
someone else will chime in.

Mark, WB9CIF

Be aware John that the early K3Ss, lower than serial # approximately 10700
or 10800 (I don't remember the exact serial #) need some modifications to be
up to current K3S production.
The mods are the IMD mod for the K3LPA and KPA3A, the fan mod and the KPOD
mod so the KPOD can be powered from the front panel KPOD jack.
I just got my K3S back from Elecraft about two weeks ago after having these
mods installed.
I believe Elecraft will perform these mods for free except for shipping to
and from Elecraft.
If I'm incorrect on that I'm sure Don or someone on the reflector will chime

Yes, Don they did charge me the $99 one-hour fee, but I did have some repair work done on the sub-receiver. So, it took them one hour or less to repair the sub-receiver and put the mods in.

Hi Peter,

You can sequence macros so that one PF button does two different functions but the two different functions still require two macro positions.  The trick is at the end of each macro you reprogram the function key to point to the other macro.  The means you have to use a PF key on the K3 because you cannot change what macro the KPod keys activate.  Tapping KPod button 3 always activates Macro 11 and you cannot change it to activate Macro 3.  And the toggling macros have to be in positions 1 - 8 because those are the only ones the PF keys can activate.  To use a KPod key to activate the toggle, you could use up a third macro slot that activates the PF key chosen and then put it into one of the macro slots the KPod can activate.


Cheers,

Fred KE7X

That?s what I was afraid of. Well, I have one more idea. I have Macro 11 (tap kpod button 3) and Macro 3 (button 3 hold) to toggle between 5w (hold) and 100W (tap). I understand there?s a way to program a macro to switch between two groups of functions. I could repurpose the tap to toggling the RF output power and toggling the hold on that button to cycle through my new macro, on and off. I just don?t know how to actually do that!

Hi Peter,

The KPod doesn't actually store any macros.  It basically gives you 16 programmable function keys in addition to the 10 available on the front panel of the K3s.  The only macros it can activate are the 16 that you can store in the K3s using the K3 Utility.

One way to add more is to use the SVGA option of the P3.  That will give you up to 50 messages/macros but they must be activated from a USB keyboard plugged into the P3 (not the P3's RS232 port, though).

If you don't like the idea of another keyboard, check out NK7Z addition of a Genovation keypad (www.nk7z.net<http://www.nk7z.net>).   www.QRPWorks.com<http://www.QRPWorks.com> has its SideKar that can store messages/macros externally but it needs to use the serial port.

Subject: [Elecraft] More macro storage



Hi all,
I have a bit of a dilemma when it comes to macros and my K3s. I own a kPod
that's fully loaded with 16 always-used functions. I just developed two more
that I will use on a very regular basis, but I have no way to command them
into the radio now. The RS-232 port on the P3 is needed to connect to a
MicroHam MicroKeyer-II full-time, so the only time I can connect the K3s/P3
to the computer directly is when I remove the CAT connection from the serial
port.

My understanding is that Transceiver macro memories mirror kPod commands,
and if that's the case, I'm not sure what I can do to fire off these two
macros (one does a series of actions, the other undoes them). These macros
are for listening to the pileup on VFO-A while locking the DX on VFO-B, and
switching the L-Mix-R values for this format (then back again with the
un-set macro). Any ideas?

Yes, the techs at Elecraft are well practiced and quite efficient.
They also run it through the automated checkout line for you.
Well worth the cost IMHO.

Hello group,
Thanks for all the replies and help. I found out that problem was me. I had
LP-PAN and a creative soundcard (external emu-202) in line with my k3 along
with my navigator interface. Disconnected the LP-Pan and external sound card
and all is working great. 
Just a senior moment and to many thing in line. 
Thank you very much for the help.

Bob,

Select the K3 in Hamlib if the KX3 is not present in the selections.
Other than that I cannot help much with the computer end setup.

FT8 is no different than other soundcard data modes.

On the KX3 part, set the DATA mode to DATA A.  Ignore the common 
internet advice for setting the audio and power levels (and the WSJT-X 
instructions), and set the KX3 audio level to indicate 4 bars on the ALC 
meter with the 5th bar flashing.  Control the power with the power knob.

There is an article on my website www.w3fpr.com to assist you with 
setting the audio level.  Scroll down to the bottom of the left column 
and click on the link.

Don W3FPR

Totally untrue!

Where did you get this information. I have many FT-8 contacts in DATA mode. 

AFSK A and FSK D modes are LSB modes for RTTY. 

DATA A and PSK D are USB modes for PSK and DATA A works with other USB modes like JT65 and FT8.

Subject: [Elecraft] OT: Still making Dot Stabilizers for Bugs
Message-ID: <em15620aa5-72f8-417f-a716-904a3f0c7e7e@jimsdesktop-pc>

CW operators and bug key users, I haven't posted this blurb on the "Dot 
Stabilizer" I make for about a year so I decided to make a Christmas 
price reduction effective immediately and it will continue until 
December 31, 2017.  Please send any inquiries direct to me rather than 
post them to the reflector to keep Eric happy and clutter to a minimum - 
LOL.

Jim Sheldon - W0EB


Semi-automatic "BUG" key Dot Stabilizer Information:

Back in the late 1920's early 1930's, T.R. "Ted" McElroy (Morse copying 
World Champion) who also manufactured telegraph keys, came up with a 
nice innovation he called his "Dot Stabilizer" which pre-loaded the 
vibrating dot contact spring by a very small amount, effectively 
ensuring better dot weighting and came very close to completely 
eliminating the contact bounce which creates what many call "scratchy 
dot syndrome". This device required replacing the existing dot contact 
assembly with his stabilizer and fit only the McElroy manufactured keys. 
For some unknown reason, most information on this device was either lost 
or ignored during the WW2 years and after.

After accidentally rediscovering it a couple of years ago, I undertook a 
slight redesign of McElroy's original device to eliminate the necessity 
for replacing the vibrating dot contact assembly. This makes the device 
easily installed and removed at any time with simple tools. I also came 
up with a further variation on McElroy's design that can be used on even 
the "Flat Pendulum" bugs such as the Vibroplex Lightning Bug, Military 
J-36 and Champion models as well as various copies of them and even the 
Japanese Hi Mound "Coffin" bug.

I currently make "Dot Stabilizers" for the Vibroplex, Speed-X and 
McElroy keys having the round pendulum and bugs with the flat pendulum, 
such as the Vibroplex Lightning Bug, Champion and WW2 military J-36 bugs 
(including the Lionel models) which are based on the Lightning Bug 
design. I can also manufacture them for other bugs such as the Japanese 
Hi Mound ("Coffin") bug, European made (metric sizes) bugs, etc. as long 
as you can supply me with the diameter (round) or thickness (flat) of 
the pendulum and a sharply focused digital photo of the actual bug you 
want it for. (I only need photos and pendulum dimensions for bugs other 
than the McElroy and Vibroplex models.)

They can be made out of either aluminum or brass though aluminum is the 
preferred material as it is far less expensive. They mount to the arm 
with a socket head set screw and the proper Allen wrench is included 
along with a printed set of instructions explaining installation and 
proper adjustment. Also, they are made entirely by hand so there may be 
slight differences between each one (won't affect the operation at all).

The prices are normally $28.50 post paid for the aluminum and $38.50 for 
the brass ones to domestic USA customers.  I'm offering a Christmas 
special price reduction from now until the end of the year.  Due to 
large postage increases and the extra, complicated Customs forms I need 
to fill out for export, this Christmas offer is just for USA domestic 
customers.

I'm offering my standard Dot Stabilizers in Aluminum for $22.50 each 
which includes postage and 32.50 each for the brass variety, also 
postage included.

If you decide to order one or more, I will need the make/model of the 
bug(s) you want stabilizers for, whether they are "left" or "right" 
handed (the bug, not you) and be sure to include your mailing address as 
well.

I take personal checks, USPS money orders (made out to Aubrey J. 
Sheldon) sent to my QRZ listed address (2029 East Evanston Dr., Park 
City, KS 67219-1618) or PayPal to w0eb at cox.net

I'll be happy to answer any further questions you may have.

Please email inquiries direct to w0eb at cox.net not to the reflector.

An observation:

I too had RFI from LED lights, but the interference was to OTA television, Channel 10 (192-198 MHz) DTV.

Not all LED bulbs are created equal in this regard, RFI reduction / elimination.  The RFI was generated in this case by the SMPS integral to the bulb.

The offending bulb is Utilitech part # 5DG6 (printed on the bulb) and is ?C  UL  US? listed, purchased from LOWEs.  

I have a overhead fixture that was populated with four 800 lumen (60w?) bulbs, 2 being Utilitech, and 2 Sylvania OSRAM.

By removing the bulbs and observing channel 10 reception, the offending bulb was determined to be the Utilitech.

I replaced the the the Utilitech bulbs with Sylvania OSRAM, and the RFI on channel 10 OTA was eliminated.

The Sylvania OSRAM part number used is LED8.5A19/DIM/0/827/G5/RP as printed on the box UPC, and were purchased from LOWEs also.

NOTE: There may be interference from Sylvania OSRAM bulbs on other frequencies.  LED bulbs are required to meet FCC Part 15 FCC, Class B regulations.

YMMV

I have not seen a comprehensive report or article that unveils ?good? vs ?bad? LED bulb manufacturer and part identification as far as RFI emissions across the spectrum.

Makes me wonder if at all or how frequently production lots are 
evaluated to determine if they are in FCC Part 15 compliance.

Otherwise, the approach "we evaluated one production lot, deemed it 
passed" {a.k.a - I saw it work once, ship it}? and then produced a 
million or so afterwards including those with some engineering changes 
and cost down changes.

Guess I need to power the radio from the tractor battery and dump the 
main breaker in the house to see how much the noise changes.

I have noticed the background noise level growing on the HF bands, and for me, especially on 18 Mhz.  I need to declare war on RFI and find out what is causing this.  I did carefully checkout some Walmart "100 W" LED lights before committing to them and they were fine.

Makes me wonder if at all or how frequently production lots are evaluated to determine if they are in FCC Part 15 compliance.

Otherwise, the approach "we evaluated one production lot, deemed it passed" {a.k.a - I saw it work once, ship it}  and then produced a million or so afterwards including those with some engineering changes and cost down changes.

Guess I need to power the radio from the tractor battery and dump the main breaker in the house to see how much the noise changes.

One thing observed at our repeater location is that the CFL was quiet until the the transmitter was on the air. It then generated noise.  In a simplex condition it wouldn't be observed. But in a duplex operation or multiple receiver situation it becomes an issue.  Replaced by a LED with lessened issues.

Bruce and all,

Do it like the manual says for DATA modes.  FT8 is just another 
soundcard data mode.

For a more detailed explanation, look at the document on my website 
www.w3fpr.com - scroll to the bottom of the left column and click the link.

Hello dear All,
I made a four bands K1 5 years ago, and ordered also at that time a K1B80

I lost assembly instruction of that 80m kit.
Does anyone have a copy of that manual?

Many thanks.

Med,

The K1B80 kit cannot be used on the 4 band board, it is only for the 2 
band board.

The K1 manual contains instructions for the 2 band board, and the chart 
of capacitors and inductors to use for each band is on the page 
following page 6 of the RF Board Parts List.

I found out first hand a number of years ago that a device that has type 
approval in the US can still spew a lot of unwanted RF. Better to have some 
approval process but it would be better if the specs were much more strict.

I worked for a company that had a pair of transceiver devices used in 
real-time data collection. The devices had FCC type approval but failed to 
pass the UK type approval process. I couldn't believe what I saw when I put 
the devices on a spectrum analyzer. The main oscillators operating in the 
27MHz and 49MHz ranges had harmonics galore up in to the gigahertz range. It 
made me wonder if the original designer ever checked the devices with an SA. 
I was able to fix the problem for both devices with trivial changes and the 
devices then passed the UK approval process.

The FCC (or was it ARRL) is doing a study/survey about the increasing noise 
floor in the RF spectrum. It no longer surprises me that the floor is rising 
when the US approval process is so lax.

Cheers!

Kevin.

As I understand a company can perform self certification.  There seems to be no independent audit system.   Thus if the company says it meets specs, then it meets specs.

Something to consider is what noise is 
coming in on the cable after you pull the 
breaker on the house. I did that and found 
the AM portable went nuts next to the 
breaker box. Found the noise is coming in 
off of the cable lines. Zero luck with the 
cable company...

Just sayin'

I am sometimes asked if 80 meters can be added to the 4 band board, and 
the answer is not without sacrificing two of the 4 bands - making it a 3 
band board.

The low pass filters are shared for two bands each - that works for 40 
and 30 meters, and also for 20 and either 17 or 15 meters.
But it will not work for 80 meters because the 2nd harmonic will be in 
the 40 meter band vicinity and will not be suppressed.
Besides, it would require a lot of experimentation to get the Pre-mixer 
and RF Bandpass filters at the correct frequency.

Hello Jim,

Something that might help you in your RFI fight is being able to 
accurately define your RFI environment.  See:

http://nk7z.net/sdr-rfi-survey-p1/

for a brief write up on how to use an SDRPlay RSP-1 to look at your 
entire RFI environment, shown as a spectrogram, of frequency vs time, 
across a 24 hour period.

73s and thanks,
Dave

A year or two ago, W3LPL taught us that this is the result of passive 
intermod generated either by the diodes or the SMPS or both. We see this 
in our CW contesting trailer, where CW operating frequencies on 80, 40, 
and 20 are harmonically related. We run K3, P3, KPA500, KAT500 to 
individual single-band dipoles with feedpoints within a few feet of each 
other. The 40 and 80 feedlines both have double stubs, placed along the 
line to maximize their effectiveness per this app note 
http://k9yc.com/LocatingStubs.pdf? and all antennas have common mode 
chokes at the feedpoint.

If we park in the middle of nowhere, the stubs bring the power amp 
second harmonic down to the point that we can operate within 10 kHz or 
so of it. If, however, we set up close to civilization, some piece of 
gear, usually an SMPS, receives our fundamental, generates the harmonic, 
and re-radiates it.? During CQP two weeks ago, we thought we were in the 
middle of nowhere (a remote mountain ridge in the Sierra), but then saw 
a cell tower a half mile or so away.? My experience? has been lots of 
noise sources at these sites, and something(s) near us were generating 
lots of harmonics.

Last week I was working the Makrothen RTTY contest at home, running 
about 1 kW between 20and 40 with antennas whose feedpoints are 5-10 ft 
apart. Usually that's not a problem, thanks to double stubs on the 40M 
antenna, but that day I heard lots of passive intermod and saw it on the 
P3. Then at some time in the morning the intermod disappeared. I'm 
guessing that the offending device was moved, turned off, disconnected?

Good Evening,
 ?? When I first moved to the Pacific Northwest I had to learn the 
subtle difference between showers and rain.? Rain can start on Monday

possibility of cessation.? The probability of seeing the sun during a 
rain storm is at or near zero; during periods of showers the probability 
rises into single digits.
 ?? The sun is still blank but not inactive.? Solar winds are causing 
aurora which means there are some ions reaching the Heaviside layer.? 
This is good.? Even though there will be flutter, wows, and all manner 
of odd noises there should be propagation to somewhere.

That's always the first step in chasing RFI.  If that does it, then trip
each individual breaker one at a time and see which one(s) stop the
noise.  It's not rocket science and a lot easier  than starting with
appliances/lamps as the first step.

It started going downhill when the FCC in its infinite wisdom (my
employer at the time) decided to shift most of its responsibilities,
including  the equipment approval process, to the private sector.
Depending on what the relationship between  the testing lab and the
manufacturer is, the testing may be above-board or just "stick on a
label".  Then we have the problem of the "laboratory queens" where
devices submitted for testing are tweaked into compliance just for that
purpose and they bear little or any resemblance to the devices shipped
to the market other than cosmetic.  The cheap-o Chinese radios are a
prime example.  The volume of electronic devices shipped from overseas
has so overwhelmed both the FCC and the US Customs that they have
stopped requiring and processing  the former Declaration of Conformity
(FCC Form 740) for importation.

Enough ranting....

Not zero --- one of the few things that the FCC field enforcement is
still doing involves responding to complaints of leaky cable systems
because of the possibility of signal leaking in the Aviation and Public
Safety bands.  They won't do anything unless the affected party makes a
complaint, though. 1-888-CALL FCC  (1-888-225-5322).  The magic words
are "cable signal leakage causing interference to communications".

Some combination of K3S and P3 settings, or just wheel the Big Knob around?

Bret,

You can use the waterfall display on the
P3 and SVGA option to see the relative speed of the dots and dashes 
being sent.  I suggest that is your best alternative.

Once you find one that is sending at about the speed you want, then turn 
the "big Knob" to that station.

It may take some tuning and listening time to familiarize yourself with 
the speeds being sent by other stations.
You can use the ARRL code practice and/or bulletin transmissions as a 
guide.  The bulletins are sent at 18 wpm.

73,

Hi Bret,

You can turn on CW decoding in the K3S and see the decoded CW and the CW speed in the VFO B display area.


Hold TEXT DEC and tune VFO B to WPM CHK.  You can also choose TX ONLY to check your sending, CW 5-40 and CW 30-90.

Tune VFO A to adjust the decoding threshold.  thr AUTO is a good place to start.


CW decoding works best when you are tuned to the zero beat frequency.

Turn CWT on by tapping  CWT and then tap SPOT to automatically slide you in on the correct freqquency.


Now turn the big knob to a CW signal you see on the P3.


Cheers,

Fred KE7X

    Hi.

    A lot of the LED QRM issues, are caused by the PSU, or "Electronic
    Ballast" dropping into a discontinuous conduction mode within it's SMPS
    when low voltage halogen lamps are substituted with LED types.  Change
    the "Ballast" or re-fit enough Halogen types to keep it happy (and quiet!)

?	It's also worth noting, that the EMC regs for unwanted emissions from
    electrical/electronic equipment, is designed to protect Broadcast
    services, where signal levels are often several 10's of dB greater than
    those that we are interested in.

?	So, it is quite possible for a fully approved gadget to pass all the
    required emissions tests, and still create mayhem on HF in particular.
    Also, in the EMC world, for commercial products (sold to the likes of
    us) it is assumed that nothing "radiates" directly from itself, as it is
    too small a fraction of a wavelength, so only conducted tests are done,
    and on artificially loaded leads and cables.

	Of course, add such things as long speaker leads, other gadgets, and you
    have a situation where a collection of fully approved pieces of (for
    example) domestic cable/satellite TV equipment, where each on it's own
    is fine, when used together cause trouble.
    
    	It's what happens when committees create test spec's.    That and
    commercial pressure to go the TCF route (Technical Construction File)
    where a technical appraisal is done on the design, resulting in a
    statement that it is believed no problem will ensue, and again, the
    product itself is never tested in practice.? Cost saving pure and simple.
    
    	Then you also get creative installers who adapt and modify things,
    causing trouble, for example using unscreened leads between a variable
    frequency drive inverter, and the motor it powers, purely because
    screened power cable is expensive.  Or, they don't correctly ground the
    shield rendering it useless.
    
    	Similarly, some of the modern LED based traffic signals, should have
    screened cables, but don't, purely because of the cost of replacing the
    old cabling with new.
    
    	And we haven't even touched VDSL and G.Fast used for broadband
    connections from fibre enabled cabinets, and the noise they can produce,
    or in house Power Line Networking.
    
    Have Fun.

Hello,
     I have my FT8 software set up, and am using an external E-MU 0202
soundcard. On the KX3, I am using DATA A, with soundcard output going to the
KX3 mic input. I have made a couple FT8 contacts.  But the ALC setting
remains puzzling to me. I have read Don Wilhelm's setup notes for the
digital modes, but what I am seeing does not agree with the notes. I am
unable to see any ALC bars. I set power on zero, and essentially set the
audio input to what sounds good (MIC Gain midscale), then up the power to 10
watts.
     If I try to change to the USB mode, the FT8 software switches the KX3
back to DATA when I click the FT8 Tune button. That may be fine, but no
matter what I do or how I set the audio input, I don't ever see any bars on
the ALC meter.  
     Must be something simple I am overlooking?

Ed,

Perhaps you are driving the audio of the KX3 too hard.  The KX3 has an 
"quirk" that it uses for protection from too much audio by reducing the 
input signal drastically.

Try reducing the soundcard 'speaker' slider and the 'power' slider in 
WSJT-X to see if the audio input level to the KX3 is too great.

If that is the problem, then an attenuator - 10k in series with 1k 
between the audio line and shield - in the line should help.

Remember that the MIC input of the KX3 is microphone level, and you are 
likely driving it with 'speaker' level from the soundcard.  Microphone 
level is in the range of 200 to 600 millivolts while the speaker output 
from the soundcard is in the range of 1 to 3 volts - BIG difference.

73,
Don W3FPR

Ed,

Perhaps you are driving the audio of the KX3 too hard.  The KX3 has an 
"quirk" that it uses for protection from too much audio by reducing the 
input signal drastically.

Try reducing the soundcard 'speaker' slider and the 'power' slider in 
WSJT-X to see if the audio input level to the KX3 is too great.

If that is the problem, then an attenuator - 10k in series with 1k 
between the audio line and shield - in the line should help.

Remember that the MIC input of the KX3 is microphone level, and you are 
likely driving it with 'speaker' level from the soundcard.  Microphone 
level is in the range of 200 to 600 millivolts while the speaker output 
from the soundcard is in the range of 1 to 3 volts - BIG difference.

73,
Don W3FPR

It's been reported that both K3s on this expedition have failed, although one 
was apparently repaired and they are limping along.

Has anyone heard what the failures were?

Hi Wes,

If you read all the 3C0L updates they have been reporting issues with the
generators and power supplies.
As such I'm guessing they had an over voltage issue and blown one of the
protection diodes on the RF board or in the KPA3
It's too bad, I could of used them for some band fills.

Maybe I'm just lucky.
Over the last two years I changed out all the incandescent and CFL bulbs 
in this house save two. They are the two 150W Halogen lights I have to 
illuminate the garage/driveway/deck if someone gets too close to the 
house at night.

No RFI detected on a K3 or a K2.

Currently Dollar Tree has a set of 60W sunbeam LED lights on sale for a 
buck each, and they are dead quiet.  I bought 20 of them today, and 
swapped out every light in the house.  Lost about half an S unit of noise.

73s and thanks,

Message-ID: <CAPw5zB2TJb3pK+Yrq2_dKkGhQz7623CbQA0KFmumOwQXsf9D-w@mail.gmail.com>

I have a K3s/10 (12 watt version) which I intend to use in the upcoming cq
ww cw contest.  This unit does not have KPA3A power brick and cooling fans
installed.

While doing some trial runs I noticed that the area around the KLPA3A power
transistors is getting fairly hot after prolonged contest use.  My guess is
the transistors are working harder when used as finals.  The rig needs to
produce between 6 and 12 watts to properly drive the SS amp I intend to
use.

Looking for some opinions:

1.  Don't worry about it.  I am paranoid.  The KLPA3A power transistors can
sustain the rigor of 40+ hours use in the contest.  Just make sure they are
properly fastened as directed in the assembly manual.

2.  Rig up some passive thermal cooling.   Perhaps a heat-sink underneath
the rig to allow heat to dissipate.

3.  Mount a 12v cooling fan somewhere to allow for airflow underneath the
radio to take away excess heat.

Part of the reason they look so yellow is the low CRI, or color rendering
index. Many bulbs lack deep red, so they look yellow even though they meet
the color temperature spec, they do it by having blue and more yellow and
tricking the measurement. Note that the CRI normally used is still not that
representative of the human eye. There is a newer version rarely used
because most bulbs would come out lousy. The human eye is used to black
body radiation, with a specific mix of colors. Even 2700 k can be perceived
as white if it is close to the black body curve.

I have found two bulbs that are in the 2700 to 3000 color temperature range
that look good. There are Cree TW series ones with high CRI, but 80% of
those I bought failed in three years. I did measure them to have low
conducted emissions with a clamp on probe made from a clamp on ferrite bead
and a spectrum analyzer.
More recently, I bought GE reveal LED bulbs that look good, but have not
measured RFI yet. and have no long term reliability info. These are used in
the XYL's craft room and she complained about the yellow looking ones, but
still likes the lower color temperature. These two types of bulbs are very
expensive compared to others.

Here is some light reading:

I must have at least 30 LED bulbs around the house ranging from ?W to 23W (eq. to 120W incandescent flood light).
Most are in the range of 25 to 60 Watt equivalent (200 to 800 Lumens).
Some are 5 years or more old and are from many different manufacturers.
 The distance to antennas is anywhere from 12 feet to 150 feet.
Admittedly, I have never actively gone so far as to turn off each one individually, but I don?t seem to notice any extra RFI anywhere.
There ARE a couple dimmers that raise holy heyull, but I make sure those are off when operating.

That said, it may be an eye-opener for me to have my wife selectively switch the LED's on/off while I listen to the bands.

73, Charlie k3ICH

As a side note (to an already off topic thread), I bought a couple timer switches that do NOT use dimmer type (= NOISY) switching.
They are Intermatic, "Heavy Duty Timer", model ST01K, about $30 at Home Depot.
They use a latching relay and are battery powered (CR-123) which is supposedly good for about three years.  
They have their own clock/timer that runs regardless if the AC is on or off, and also takes into account daylight savings time.
They replace regular wall switches and I use them to control the living room lights and circulating fans in the winter for the wood burner in the basement.
They can be programed for four different modes with two variables, Time on/time off, and/or Dusk on/Dusk off.
The living room lights are set for dusk ON, and 2300 OFF.  
That way I don't have to monkey with a mechanical timer, resetting as sunset varies or we lose the juice in a storm.
The fan control is set to come on at 0630 and go off at 2330.
During the summer, the fan switch is in its manual mode (OFF), because they're only needed in the winter.
Another nice feature is an override button which when punched will change the state of the powered device.
They're somewhat of a bear to program, but they DO exactly what they're supposed to AND, except for the initial ON or OFF switching, make absolutely NO RF noise.

The only time I've noticed RFI issues from CFL or LED bulbs is when they 
are being excited by RF.? I've measured 3 or 4 different ones of 
different brands and wattage ratings.? This was done using a fixture 
where by the bulb was mounted on a suitable surface in a socket with the 
transmit antenna {dual band VHF/UHF}? some 6 ft away from the lamp and 
the receive antenna {connected to a spectrum analyzer with a similar 
dual band VHF/UHF antenna}, about 6 ft from the lamp.? In all cases no 
noise above background noise was observed.?? When the transmitter was 
activated, the spikes of noise appeared.? With the transmitter off, the 
spikes again were not present.??? Not a real analytical or scientific 
method but some degree of indication that some are better than others, 
some are worse than others.

Nick,

It all depends on your perception of "fairly hot".

My 'rule of thumb' is that if you can hold your fingers on the surface, 
then it is not too hot.

My big worry with regards to LED lights is that they have parts that are 
sourced from different makers from run to run...

You get LED lights that on one run are dead quiet, and on subsequent 
runs are not quiet...

I bought 20 of these bulbs, after testing one, and so far they all 
appear quiet.  Who knows what the next run will bring...

73s and thanks,

The K3/10 will output 12W.

That said, based on IMD measurements I have performed I would NEVER run a K3/10 
at 12W out.? Frankly, with my K3S with the latest rev KLPA3A to keep 3rd order 
IMD below 30 dBc, I would throttle it back even more above 18 MHz.

The K3/100 switches to the KPA3A at 12 watts.  So is there a 2w range  
(10-12w) where the KLPA3A is putting out unacceptable IMD?  Is there a way  to 
make the switch at 10w, or should we just avoid that 2w "danger zone"?

Sounds like classic received and re-radiated intermod, Bob. W3LPL has 
chased this down, and I've observed it in our CW contesting trailer. Set 
up in the middle of nowhere, no issues with transmitter harmonics or 
intermod. Set up anywhere around civilization, strong harmonics and 
intermod.

Yes, exactly my point.

Although one may find the local AM or FM station is "exciting" these 
lamps, be they CFL or LED.? They may, to some extent, generate the crap 
we hear.?? For us hams, when we transmit the noise may be produced but 
is not of concern in as much as they are quiet when we receive.? But as 
Jim, K9YC says, this may happen when a nearby transmitter is active, the 
nearby receiver is plagued with noise.

Clearly the CFL devices I used for testing did produce many more and 
higher level harmonics than the LED devices.?? I did not have a large 
sample of lamps, but the ones used, did show issues with the LED units 
showing less than CFL's.

I agree and I have previously mentioned this on the Elecraft list. it
would be nice if you could control when the 100W PA engages. I would
prefer 10 watts.

A few weeks ago several folks here were discussing the hanging of an

Looks neat and like a lot of fun, but around here I could hire more than
half a dozen climbs by an insured expert for the >$800 cost of the system.
And they install a screw eye in the trunk for a stable and nearly permanent
attachment. I have them install a pulley attached to the screw eye so I can
drop the antenna or replace the downhaul line as needed over the years.

Even so, a quadcopter to play with... Hmmmm...

Yes, but can your tree climber do this:

You're right - it's an expensive way to install a dipole...geared more
toward those who already have a quadcopter.

When I was changing the bulbs out I took the opportunity to remove all 
dimmers, never really used them, and a touch lamp the wife hated (large 
blessing on me).

The wife has been looking at touch faucets for the sink. They've got to 
be an RFI nightmare. I said NO. Plumber makes enough the way it is. Now 
you have to find one that can wire the faucet too. One step too far.

The wife's quilting machine is next. it's going to get the K9YC treatment.

The two pins in KX3 that mate with KXPD3 were recessed a few mm. After
pulling back, the key works fine. I must have inserted KXPD3 too hard, and
the pins gave out. 

I wonder how to secure the pins from recessing. Crazy glue, epoxy, or
something else.

Hi Don

Good question.   I happen to have a Infrared Thermometer.    After bashing
at it for about 20 minutes, the temperature in the vicinity of two
transistors (as measured against the bottom cover) peaked at 50 degrees
Celsius (122 F) but it did not go beyond that.  I ran the rig at 10 watts
on 10 meters which is where most of the drive power is needed.

I suppose that should be OK than.

73 and thanks for your feedback,

Subject: [Elecraft] In praise of the sub Rx & Diversity
Message-ID: <59F0070E.12096.2FB41BC@Gary.ka1j.com>

When I bought the k3 in 09 I went all out 
and bought most of the accessories to go 
with it. One of these was the sub Rx and a 
full matching set of crystals for it. As 
upgrades happened I did them all and 
wasn't using the Sub Rx in diversity so 
much but, the advantage of the Sub Rx was 
always there with flexibility I take for 
granted.

So I upgrade to the K3s and migrated the 
sub Rx to it as well. I just don't think 
of diversity much but that was one of the 
reasons I bought the Sub Rx in the first 
place. With the 3 dB loss going to 
Diversity, I just listened more with the 
main receiver and let it go from there.

So today I'm working a ve7 on 10M and the 
band is going out. I can hear him but it's 
at that marginal iffy point, I was missing 
characters in his CW. I have a HI-Z 
triangular & a circle 8 pair of Rx 
antennas. The Circle 8 rocks on the low 
bands, has a filter to cut out above 40M 
but the triangular has no such filter and 
I often hear better on it than on the the 
roof mounted tribander. So for fun, I used 
diversity and the triangular on the sub, 
160 sloper for the Tx antenna & Voil?, I 
heard him so much better, finished the Q 
and that reminded me of the real advantage 
of diversity and why it is an asset.

So now it's tonight, I see 3C0L is still 
on the air at around 3AM their time, on 
20M. They're heading home today and the 
low band antenna is packed up already. 
What troupers to still be in the game at 
this point. But I digress... So here they 
are, I don't have a good antenna for 20M, 
have to use the 160M antenna or tribander. 
RFI from the neighbors makes the tribander 
useless so I hear them on the sloper and 
can hear them on the Hi-Z Triangular a bit 
better but much QSB so remembering the 
success with the VE7 earlier I go 
Diversity & all of a sudden, solid Q5 
copy, no QSB and I snagged them on 20 CW.

Diversity really made the difference. I 
bought the K3s because it had such 
excellent specs, nothing else to me came 
close, save for 1-2 radios that in 09 were 
hot and cost more than a new car. And they 
weren't any better in practicality than 
the K3 was. I bought the Sub Rx for the 
diversity and now today, while the K3s is 
itself stellar in all the right ways, it 
is an a better product with the Sub Rx. 
I'm really honored to have such an 
incredibly capable radio.

Just sayin'

73,

Oh, it can descend with the line attached, just not gracefully.
Reminds me of when a Marine Corps Major asked if he could test fire a
Stinger missile over the Potomac River, to which my boss replied.
Maybe....once.

Interesting.
I have a 5 servo 8ft Helicopter, been flying them for years, but I've always used an old 12ft fishing beach caster with 30lb line and 5oz fishing weight..
I can zip it over a 100ft tree, tie on a light line, reel the fishing line back in then you can haul up the dipole end.
Takes a few minutes to set a full 160m dipole between 2 suitable trees for Field day. 
Look out for one at your next boot / flea market sale!!

The problem appeared suddenly. When KXPD3 was inserted, KX3 started sending
dahs. With KXPD3 not fully screwed, keying was OK. 

What happened was that the two bottom pins in KX3 that mate with KXPD3
recessed, touching connections with the upper pins. Then, the ground pin
became the dah pin.  When KXPD3 was not fully inserted, the recessed pins
did not make contact; the ground connection was through the screws.  

I pulled and resoldered the pins. Now everything is fine.

Seems a bit artificial problem, unless someone is driving an amp that
requires 12 W. My modified Expert 1.3k-fa requires about 6W to 8 W for 1 KW
output.
 
If a serious concern, increase voltage to 15V. The Yahoo KX3 group has
graphs of IMD3 as a function of power and voltage. Increasing voltage at 12
W by 1 V decreased IMD3 by about 10 db. I assume that the LPA in K3 is
similar to the amp in KX3.

I checked out a few youtube videos, especially "drone fishing" ones, and 
a less expensive drone with a kinda T-shaped wire (a very flat "hook" 
parallel to the ground) could work very nicely.

The release mechanism is cool, and certainly the "GPS Hold" function is 
neat, but they add cost.

The trees I want to use won't support a climber very high.

Personally, I would, and do, avoid that region.? The difference in received 
strength between 10 and 12W is imperceptible if the HPA isn't installed. If it 
is installed, crank the power up to 20 or so and you're out of danger.

Hi all,

I?ll be speaking about the KX2 at the FARS meeting this Friday night. Among other topics, I?ll cover the KX2?s ancestral lineage (shamelessly cherry-picked QRP rigs of yore), its technology and design goals, field applications, and lightweight antennas. I?ll be bringing a prototype of the Elecraft AX1 two-piece whip.

FARS meetings are open to the public and all are invited. The meeting will be in the multi-use room at Covington School, 205 Covington Road, Los Altos. Nearest freeway exit is I-280 at El Monte Road.  The school is about 5 minutes from the intersection of Covington and El Monte Roads.  Doors open at 7 pm for socializing. Meeting starts at 7:30 pm. My presentation will start between 7:45 and 8 pm.

Hope to see some of you there.

You're welcome. It is such an oasis to 
find a company that not only makes top 
quality equipment but has a fantastic 
after sale support of these products.

I Loved my K3, sold it to a friend who 
wanted one for mobile contesting, with me 
buying a K3s to replace it. Feeling 
remorse at selling the K3 & having to use 
a Corsair II as my only backup rig, I 
bought another (very old) K3 again for a 
backup in case I have to sent the K3s 
back.

I don't hear much about the Diversity 
option mentioned here any more and thought 
I'd bring up how much of an advantage it 
can be, even with all the stand-alone 
stats of a K3s. Diversity still makes the 
K3s an even better, more capable radio. If 
you want the best of the best, Diversity 
gives you that option.

Barry,

The normal recommendation is for 50% of the maximum power.
The KX3 and the KX2 will roll back power for protection if the PA 
transistors get too hot.
I know the KX3 rolls back to 5 watts, but I am not sure about the level 
for the KX2.

Thanks Tom and Don for the responses.  I'll try a few 15sec FT8 xmit cycles
at 50% (7.5W) into a dummy load while monitoring PA temp.  Any guidance on
what the upper safe limit is for PA temp?

Barry,

You should be able to tolerate 60 degC measured at the PA transistor 
tabs for short periods.

You can read the PA temperature in the Alternate VFO B display.

Message-ID: <CA+WqgiaFq1Tynh7bO=BiCLwiy2N8NOAVeLvdVwZ-2doj=pBifQ@mail.gmail.com>

Hi all

It doesn't have to cost $800.

A couple of years ago I bought a Chinese quadcopter, complete with video
camera, 2GB micro-SD card, card-reader, spare propellers, 2.4GHz remote
controller, and including shipping - all for $68. But I think the price has
come down now. The total "diameter" of the thing is only 35cm or so. The
quadcopter at time of purchase, had various optional attachments you could
choose, not just the video camera. There were things that fired little
darts and stuff like that. So basically there is a spare channel which is
operated by a button on the remote control, no need for an additional radio
transmitter. Of course it doesn't have things like GPS hovering and you
don't want to fly it in any kind of wind, any at all.

I have a plan to hoist a wire over my next door neighbour's tree. My
previous attempt to THROW it over the tree by standing on my rooftop did
manage to land in the middle of the tree but was hardly OVER it, and in
hindsight trying to throw it while balancing on the roof didn't seem like
it would increase my life expectancy any. A storm took down the wire. And
the quadcopter seems a better solution.

A few weeks back, I did go out one morning early, before the sea breeze
started up. I was all ready to give it a go, but I discovered that the
fishing line I have is a little too short. Then I remembered how one
earlier attempt at throwing fishing line into the tree from the roof had
resulted in a lot of tangled up line which had to be thrown away. Now I
have bought some more line and yet to get around to a retry.

Even that tiny cheap quadcopter had plenty of power to lift the fishing
line to around twice the tree height (I guess about 60 feet), and it had
still enough power to lift the plastic reel that the end of the line was
tired to.

The KX3 specifications in the manual (page 54) say 5 W for digital modes. I expect the KX2 specs also list a power level.

"Supply voltage of 11 V or higher (on key-down) required for settings above 5 W.
5 W or less recommended for high-duty-cycle modes (FM, AM, DATA). Power will
automatically be reduced if PA temperature or current limits are exceeded."

Don't think so from the description Wayne gave on the KX3 Yahoo group.

Folks,

I thought I should also share these 
additional thoughts about diversity & 
Elecraft, the company as well, with the 
group: 

It is such an oasis to find a company that 
not only makes top quality equipment but 
has a fantastic after sale support of 
these products.

I Loved my K3, wanted a K3s and sold the 
K3 to a friend who wanted one for mobile 
contesting, with me buying a K3s to 
replace it. Feeling remorse at selling the 
K3 & having to use a Corsair II as my only 
backup rig, I bought another (very old) 
but fully updated K3 for a backup in case 
I have to send my new K3s back for repair.

I don't hear much about the Diversity 
option mentioned here often and thought 
I'd bring up how much of an advantage it 
can be, even with all the stand-alone 
stats of a K3s. Diversity still makes the 
K3 and now, the K3s an even better, more 
capable radio. If you want the best of the 
best, Diversity gives you that option.

73,

Gary

The KXPA100 blinks a LED while ATU TUNE is in progress.  The ATU TUNE needs
steady carrier from your KX2.  ATU TUNE is done with exciter power, and when
it's complete, the amp can be switched in.

Sam,

That is normal operation while the KXAT100 is tuning.  See the KXPA100 
manual page 25 "ATU Tuning".

The power is limited to 25 watts while the ATU is tuning and the 25/SWR 
LED under POWER OUT blinks.

Note that ATU is different than TUNE - see page 19 in the KX2 manual.

I don't know all the technical details of diversity reception but have 
wondered if a diversity mode option board could be produced at a cheaper 
price than a full-blown sub receiver. Not sure how much I'd be willing 
to pay but sub-receiver pricing is definitely a no-go.

Probably not. Diversity reception works because there are two matched receivers, even matched in phase of the detected audio. That allows the best signal to win based just on the signal, not the receiver.

I use diversity on 20 meters with a vertical SteppIr and a loop.  Both are separated about 150'. What a difference.  Amazing.  Makes a huge difference with stations fading in and out and near the noise level.  I can work them with the Loop, but the vertical is so helpful when receiving.

Subject: [Elecraft] In praise of the sub Rx & Diversity

When I bought the k3 in 09 I went all out and bought most of the accessories to go with it. One of these was the sub Rx and a full matching set of crystals for it. As upgrades happened I did them all and wasn't using the Sub Rx in diversity so much but, the advantage of the Sub Rx was always there with flexibility I take for granted.

So I upgrade to the K3s and migrated the sub Rx to it as well. I just don't think of diversity much but that was one of the reasons I bought the Sub Rx in the first place. With the 3 dB loss going to Diversity, I just listened more with the main receiver and let it go from there.

So today I'm working a ve7 on 10M and the band is going out. I can hear him but it's at that marginal iffy point, I was missing characters in his CW. I have a HI-Z triangular & a circle 8 pair of Rx antennas. The Circle 8 rocks on the low bands, has a filter to cut out above 40M but the triangular has no such filter and I often hear better on it than on the the roof mounted tribander. So for fun, I used diversity and the triangular on the sub,
160 sloper for the Tx antenna & Voil?, I heard him so much better, finished the Q and that reminded me of the real advantage of diversity and why it is an asset.

So now it's tonight, I see 3C0L is still on the air at around 3AM their time, on 20M. They're heading home today and the low band antenna is packed up already. 
What troupers to still be in the game at this point. But I digress... So here they are, I don't have a good antenna for 20M, have to use the 160M antenna or tribander. 
RFI from the neighbors makes the tribander useless so I hear them on the sloper and can hear them on the Hi-Z Triangular a bit better but much QSB so remembering the success with the VE7 earlier I go Diversity & all of a sudden, solid Q5 copy, no QSB and I snagged them on 20 CW.

Diversity really made the difference. I bought the K3s because it had such excellent specs, nothing else to me came close, save for 1-2 radios that in 09 were hot and cost more than a new car. And they weren't any better in practicality than the K3 was. I bought the Sub Rx for the diversity and now today, while the K3s is itself stellar in all the right ways, it is an a better product with the Sub Rx. 
I'm really honored to have such an
incredibly capable radio.

Just sayin'

My problem when I miss is getting the weight to go back up without tangling or coming right back at me.  I made a Pipe cannon using bicycle pump compressed air with a sprinkler valve opening with two 9v batts.  The same issue watch out for the weight.  I use a pair of caps on smaller pipe, but that can still be an issue.  Now to find a use quad copter.

Interesting.
I have a 5 servo 8ft Helicopter, been flying them for years, but I've always used an old 12ft fishing beach caster with 30lb line and 5oz fishing weight..
I can zip it over a 100ft tree, tie on a light line, reel the fishing line back in then you can haul up the dipole end.
Takes a few minutes to set a full 160m dipole between 2 suitable trees for Field day. 
Look out for one at your next boot / flea market sale!!

I did this years ago and even had it published in QST.  It was at least 4-5
years ago.

It was a basic Quad copter, a simple Wii flight controller and a dedicated
servo that pulled a pin out of a block to release the weight.

It worked very well.  I should get the pick back on my QRZ page.

I bet I had less than $100 invested.

Drew,

True diversity reception requires 2 receivers which are locked together 
in not only frequency, but also in phase.
The KRX3 receiver is of the same design and implementation as the main 
receiver, making diversity reception possible.

The antennas must be different, one horizontal and the other vertical as 
one example although other combinations are possible - not only 
differing polarization but oriented in different directions.

The result is that an "option board" for one receiver will not create 
the conditions necessary for diversity receive - two receivers can 
produce that result.

Don W3FPR

GA,

I have used CSV19 from:

http://www.antennalaunchers.com/antlaunching.html

Best way to use it is: one club-member has it and use it,

but service is available for all members.

This way the antenna will be launched OVER THE TREE.

All styles have been tried: army launch, sling-shots, shotgus etc.

This has been absolutely number one up to now.

Hydrocopter is promising if used properly.

Benny?? OH9NB

Message-ID: <C6D0B919-179C-462D-B9D6-96C1D9C4FAF3@micha.st>

Dear community

I am having problems with my K2. I got complaints about a lousy signal (e.g. rst 591). When I checked my signal with an external RX I heard a kind of a noise instead of a clean CW signal. When I press the "Tune" button, I have a very clear tone (as usual) in the control-RX. With all power levels the PA current is the same both in tune and in normal CW TX-mode. Only the resulting signal is different.

What could be the root cause of this issue? Are the signal paths of CW-TX and tune different to each other?

Any hint is highly appreciated.

Best regards
Micha, DF4WX

Micha,

The signal paths for TUNE and CW transmit are the same from the MCU outward.

However, I recently repaired a K2 with the same problem.  The problem 
was traced (using a spectrum analyzer) to RF Board U4 in that particular 
case.

However, your problem could be different - look at the keying waveshape 
components first (Control Board U10A and Q8) as well as the PLL 
Reference Oscillator.

FWIW ... with one of the KX3 aftermarket heat sinks, and after I 
performed the VFO Temperature Compensation routine, I was regularly 
doing 10W on the rig with JT65 with its 42 sec Tx cycle.?? The heatsink 
did get warm enough that it worried me, and I added a salvaged 12v fan 
from an old desktop computer to assist, but I never had it shut down due 
to the heat.?????? If you have one of the KX3s without a heatsink, I'd 
definitely get one and install it.

I don't think you are going to have much luck with a $49.00 drone.

I built my own and chose the spiderwire fishing line.? Works great.? The 
fishing line is hard as heck to see? but super strong.? Goes over 100ft 
trees with no effort.

50C is not hot for a transistor. Commercial transistors are usually speced to 85C. JANS (space) transistors are speced to 125C and actually baked without bias for 320 hours at 200C. The hFE is measured before and after to check for change.

lot of negative comments on some lists,  this puts it in perspective.



   Regarding K3s - those who posted negative comments on DX-Cluster about
failing K3s, please bear in mind the conditions they were being operated
at 3C0 (jumping mains voltage 120-180 V). If you dare to test transceiver,

for about 12 days, then lets compare the results."

I'm going out on a limb. I've heard that some other DXpeditions had K3 
failures in the RX section.  RX dead TX OK.  Apparently, the protection 
circuitry was not enough in the close quarter multi-transmitter 
operations.  It would be nice to know the details or if this or is just

Message-ID: <e84c533b-1b74-f7cc-6467-71308378c354@necg.de>

Hi,

just setting up for WWDX SSB and probably due to too much RF around 
(HIGH RFI indication shortly on the display) my K3 main RX died. Seems 
the 2nd RX is still operational, at least I can hear signals when 
switching to AUX antenna which is wired from ATU to sub-RX if I remember 
correctly.

Any hint?

Seem to remember there were similar cases in the past where a protection 
diode died which was not on the main board but somewhere else?

Thanks,

I doubt if anyone expects the receiver to survive if you hook the output of
even a 10 watt transmitter directly to the receiver antenna connector. If
the layout of a multi-transmitter site does not include consideration for
substantial separation between antennas, there will be failures. 

The K3/K3S receivers (sub and main) are protected by carrier-operated relays
that shunt signals to ground in the event they are strong enough to cause
damage. Of course any protective device can be defeated (or destroyed) if
punished too hard. 

Successful multi-transmitter operation begins with a rational antenna layout
considering the power levels involved. IMX, we've always used at least one
wavelength between transmitters running 100 watts or so (250 feet on 80, 120
feet on 40, and so on) and we orient the antennas to minimize coupling.

Subject: [Elecraft]  Did I fry my KXPA100?
Message-ID: <5475025C66F34818BBF4F4DB9EB6A72A@DESKTOPAV61F2H>

HI,

I seem to be having troubles with my KXPA100.
There is no power output as indicated on the power out display on the amp either into an antenna or dummy load.  The amp?s TX light does go on.
If I open the KXPA utility and look at the Operate section, Input power always stays at 0, even though the KX3 shows power output near 100W on it?s power display except when you press the Tune button.  Then it shows 10W

Sending the output of the KX3 to a dummy load shows that the amp is getting 10W power ..
If I transmit on the KX3 into the KXPA100 with 10W, the Operate section in the KPXA utility shows the following:

Input Power = 0.0
Drain Current = 4-8A (using voice....)
Supply Voltage 13.4V
Dissipated power = 50-90W

Forward power = 0
reflected power =0
Last SWR= 1.2

This is into a dummy load or antenna
Holding down the tune button the KX3 shows Input power at 10.0 but of course the amp then goes into bypass.
Anyone have any ideas?
Thanks, Tom

Tom,

Did you connect the KX3 Keyout signal into the KXPA100 PA KEY input? 
That is necessary for 'Basic Operation' - see page 18 of the manual.

This is far too conservative, and a far too limited approach.? I can 
offer several examples.

At home, I have two 3-el 20M Yagis spaced about 130 ft, and regularly 
use two K3s to drive two 1,500W amps. If I aim those two Yagis so that 
their driven elements are approximately colinear with each other, I can 
operate CW on the same band within 60 kHz of each other and not know the 
other is there! I first experienced this about four years ago with the 
original K3.

Successful multi-transmitter operations require both very good radios 
and very good SYSTEMS ENGINEERING. I regularly operate from W6GJB's 
contesting trailer on county expeditions for CQP and 7QP. From the 
trailer, we regularly run two stations, each equipped with a K3, 
P3/SVGA, KPA500, KAT500, and W3NQN bandpass filter sets. We mostly work 
CW, and usually have the two stations on adjacent harmonically related 
bands. The 80M and 40M antennas each have double stubs inline to 
suppress amplifier harmonics, and there is a serious common mode choke 
on each antenna at its feedpoint. Antennas for all three bands are 
within about five feet of each other on a 46 ft pneumatic mast.? The K3s 
have the new synth boards installed.? There are photos of the trailer at 
k9yc.com/7QP.pdf? Since these photos were taken in May 2016, Glen 
(W6GJB) has rigged the tri-bander to be at the top of the mast above the 
40M dipole.

For CQP, we run at least one SSB station in addition to the two CW 
stations, and we regularly operate CW and SSB on the same band. This 
does, of course, require good separation of antennas, and, when 
possible, colinear alignment. Operating from the same site for several 
years with colinear alignment of the antennas, we found that 200 ft was 
sufficient running tribanders on 20, 15, and 10, and 300-400 ft was 
enough on 40 and 80 with dipoles. The SSB station(s) have the same 
equipment as the CW stations.

As to failures at 3C0L -- the generator regulation failures could easily 
fry power supplies, which could include frying their regulators, which 
could fry the K3s. But the failures could also have been the result of 
poor system engineering, or operator errors, or both. Every human being 
I've ever run into screws up now and then, especially when we are tired.

As the examples cited above clearly show, there is far more to a 
DXpedition or contest than hooking up a bunch of radios to a bunch of 
antennas! The most successful of these operations have team members who 
are good operators and are worker bees, and at least some who are good 
engineers. I've seen drawings for the setups for DXpeditions that 
demonstrated careful planning and great engineering. The 2008 VP6DX 
expedition is a great example. It used some of the very first K3s to 
come off the production line, and the systems engineering was 
spectacularly good. Be sure to look at the site map and click on it to 
blow it up to see the antenna layout.

Hi,
No, I didn't.
However, it seems that the amp is not blown.
I have no idea what's happening...

Ok, Elecraft recommended a TX Gain calibration.  That was successful on all 
bands.
I changed all the RF cables and the KXPA100 still shows no output...

However, this was on 20m.
If I switch bands, the KPXA100 is working fine on all other bands.  It just 
so happens that this seems to happen only on 20m.
Everything looks the same as far as I can tell, same antenna (all testing is 
into a dummy load)
So it is only on 20m.
What have I missed?

Thanks, Tom

Tom,

Did you connect the KX3 Keyout signal into the KXPA100 PA KEY input?
That is necessary for 'Basic Operation' - see page 18 of the manual.

Yes. But I believe that is Junction temperature, not case on heatsink temp.  Remember the case bottom is heatsink for those. Make sure screws are tight.

Bill is entirely correct.
Once in my prior career, I did a study of Mean Time Between Failure for 
IC circuits (same applies to transistors).? That study had to consider 
the case temperature of the IC (or transistor) with respect to the 
junction temperature.
The specification for the IC or transistor package will include a 
thermal resistance parameter, which must be considered to obtain the 
maximum temperature for the case of the device.

Bill's comment about the screw tightness is entirely correct - the heat 
of the device case must be transferred to the heatsink in an efficient 
manner.

On page 51 of the Rev 2 KPA100 manual, I found the following:

------------------
IMPORTANT: The hardware holding the RF power
transistors in place will loosen slightly during initial use.
After 5-10 hours of normal operation at 50 watts or more,
remove the KPA100 assembly and its shield, then re-tighten
the mounting hardware for Q1/Q2 approximately 1/8 turn.
-------------------

I didn't look to see if this was in other versions of the manual; this 
was the first place I looked.

Ted,

Not Q7 and Q8 in the base K2, but for the KPA100, yes tightening the 
screws for Q1 and Q2 should be done after 5 to 10 hours of operation at 
greater then 50 watts.

Yup; here it is, from the KPA 100 Manual:


IMPORTANT: The hardware holding the RF power transistors in place will loosen slightly during initial use. After 5-10 hours of normal operation at 50 watts or more, remove the KPA100 assembly and its shield, then re-tighten the mounting hardware for Q1/Q2 approximately 1/8 turn.

Message-ID: <78e1a29d-89e9-28bc-d170-21e0f4ad95ca@af2z.net>

My K3 turns on whenever power is connected, without pushing the power 
button. When I push the power button to shut down the display clears but 
remains lit-- just a blank amber display. Can only turn on again by 
recycling the power supply; the K3 Power button has no effect. Otherwise 
the rig seems to operate normally.

I reloaded the firmware and config settings but that didn't help.

This occurred  after I replaced the FP plugs with the gold plated ones. 
I replaced the PA plugs about a week ago. All plugs are mated/seated 
correctly; good solder job.

Any ideas?

Drew,

Do you have anything plugged into the AUX IO connector?  If so, remove 
it and try to power it down.
If that works, examine all the cabling to the AUX IO, that behavior is 
typical if AUX IO pin 8 is held low.

If you are using a VGA cable in the AUX IO connector, change it to a 
cable that has all 15 pins straight through.

Don,

Thanks. No, there is nothing on the ACC connector but I'll check it out; 
maybe one of the plug pins I snipped ended up back there and is shorting 
the line? Seems unlikely but will check it out.

If anyone requires someone to assist in REALLY getting "nutty" about 
thermal control/dissipation on electronic components, I'd be happy to 
oblige from my experience.
I have had some fairly extensive hand-on experience.? Once upon a time, 
I invented Arctic Silver thermal compound and adhesive. Before, during, 
and after that time I spent thousands of hours working on custom thermal 
control solutions.

It's.... an addiction.

While I've seen no evidence it was the cause of the 3C0L failures, I've always wondered how long those toroids supported only by their leads could survive vibration in transport.

The COR probably kicked in.? The sub has its own protection for high

In a temp multi-op environment it's all to easy to make a mistake. During a
W1AW op I changed bands by stepping my way there and didn't go quick enough
to avoid pausing on an active band and fried my D5 extra crispy (that was a
fun repair). After that all band changes were strictly direct entry. 73

The testimony I can give for the toroids is that I built a K2 for a long 
haul truck driver.  It survived for several years in his truck with no 
failures.
The only reason he had for for taking it out of the truck was that he 
quit driving and got other employment.

A nice tip which I use when looking for anything in any sort of .pdf manual, Elecraft included as I have accumulated quite a number of them over time is to use the search feature on the .pdf reader.  Ctrl+f on WIndows and cmd+f on Mac and type what I'm looking for.  The index and contents tables are good, but obviously can't have everything in them, so I use the find feature a lot.


Hope this helps.

I vaguely remember reading somewhere that after some number of hours of operation ? maybe 50 ? the hardware holding Q7 and Q8 onto the heat sink should be tightened, I presume to maintain good heat conduction from the tabs to the sink.  But I can?t find that instruction in the manual now.  Anyone know where I might have gotten that notion, or did I just make it up?

Ted,
?If the people at Elecraft have done their job and mounted the transistor properly with the correct torque on the mounting hardware procedure, no additional maintainance is required. I have been in the industry for a LONG time .? Three things to remember in the mounting of any RF or high power device.? Flat surfaces, minimual mating gu, and required torque. Lack of any of these will kill a device if not correct.? I have never required retorqueing parts, with one exception.? ?In 000 copper wire terminals, the copper does relax and needs to be retorqued to achieve a gas tight seal connection, but that is in industrial application.? Small RF devices only need the initial torque to be correct.

Mel,

That is NOT true for the KPA100 power transistors - and it is not 
because of initial torquing.  The thermal pads take both time and heat 
to fully conform to the heatsink and any irregularities in the 
transistor surface.

BTW, with the KPA100, Elecraft has "done their job" when the parts are 
put into the box.  This is not sold as an assembled item - the builder 
must assemble it.

I tighten those screws on every KPA100 that I service.  I am amazed at 
the number I find loose.

73,
Don W3FPR

The K2 is a kit built by the customer, not Elecraft. 

With respect, my experience is different from Mel's. In many years working electronics field and shop service industry have found that re-tightening hardware subjected to thermal stress is commonly required by manufacturers. Manufacturers routinely do that after a "burn in" period of testing before the unit leaves the factory. Elecraft customers are instructed to do it on some gear after a period of use. 

The rarity of failures in spite of many thousands of rigs in service suggests that Elecraft's recommendations are good ones. 

BTW, when Elecraft has found that a better than metal-to-metal thermal conduction is needed, they use thermal pads instead of thermal compounds. The pads are entirely adequate and avoid customers handling messy compounds. 

In commercial work, when a manufacturer specifies using a thermal compound, I use GC Type 44. It is a non-silicon based compound and so does not 'migrate' from where it was placed. My small tube has plenty left and it predates the computer "age" -  bought it sometime in the 1970's. Like the old Wildroot Cream Oil for hair they mean it when they say a "little dab will do ya" yet it remains flexible and never hardens.

Ted,
 If the people at Elecraft have done their job and mounted the transistor properly with the correct torque on the mounting hardware procedure, no additional maintainance is required. I have been in the industry for a LONG time .  Three things to remember in the mounting of any RF or high power device.  Flat surfaces, minimual mating gu, and required torque. Lack of any of these will kill a device if not correct.  I have never required retorqueing parts, with one exception.   In 000 copper wire terminals, the copper does relax and needs to be retorqued to achieve a gas tight seal connection, but that is in industrial application.

I don't have photos but my launcher is similar but the sprinkler valve is on the end and the "shooting" tube is on the end... not so compact. The overall length is 40" + and it is easy to aim.  The issue is how much air to use.  My air cavity is much shorter and I can do 70Lbs. with a bicycle pump.  I can do 90+ lbs. and agree with the spider wire.

I don't know if very many portable ops out there are using FT8.  I'm
piecing together a portable FT8 setup for my KX3 and I'm hoping to use a
Bluetooth GPS receiver to provide accurate time sync to a Windows tablet.
If anybody out there is already doing this, can you please tell me what
software you're successfully running under Windows to link the GPS data
with the system time?

Barry,

I don't have a solution to the question as asked, however ...
Rather than trying to sync the clock real time, if you set the computer 
time at home just before your outing, it should be good for at least 72 
hours.

My laptop (used only for use while away from home) keeps accurate time 
within a second or so for a good long time (several days), and should be 
usable for FT8 use if set before an outing.  Your computer may not be as 
accurate, but I encourage you to check it.  As I understand it, FT8 can 
tolerate up to 1/2 second of timing error.

73,
Don W3FPR

Not Q7 and Q8 in the base K2, but for the KPA100, yes tightening the

greater then 50 watts.

Thanks Brian, I just downloaded the trial version of NMEATime.

And to reply indirectly to Don: I checked my laptop clock's accuracy (HP
EliteBook) and it was terrible.  I had it syncing every 3 mins and saw
corrections as high as 0.3 seconds.  Add in the temperature variability of
being outdoors 0-30C, means it needs an external reference.  The GPS
receiver is a viable solution.

Yes, that! I set up NMEATime with a USB "puck" GPS receiver for EME with JT65 on a Windows machine not internet connected. Works great. Easy to setup & super accurate. GPS antenna indoors sitting on a desk sync'd fine to multiple satellites.

I have been trying along time to get buyers to go for it and get the sub rx 
for its many pluses.  One that is kind of not obvious is the diversity 
receive. I knew about it from my years of working on FAA radars, and 
military search RADARs maintained by the FAA. All search radars from way 
back have diversity RX, because it will find those small target weak 
reflections. And some specialized diversity receive is being developed for 
those dog gone drones.  I have not measured the sensitivity of the K3s, but 
there are weak stations that are not heard when not in diversity. A friend 
in the city of Spokane can adjust the phase between his antennas and null 
out some strong RFI completely!

I use diversity on 20 meters with a vertical SteppIr and a loop.  Both are 
separated about 150'. What a difference.  Amazing.  Makes a huge difference 
with stations fading in and out and near the noise level.  I can work them 
with the Loop, but the vertical is so helpful when receiving.

Subject: [Elecraft] In praise of the sub Rx & Diversity

When I bought the k3 in 09 I went all out and bought most of the accessories 
to go with it. One of these was the sub Rx and a full matching set of 
crystals for it. As upgrades happened I did them all and wasn't using the 
Sub Rx in diversity so much but, the advantage of the Sub Rx was always 
there with flexibility I take for granted.

So I upgrade to the K3s and migrated the sub Rx to it as well. I just don't 
think of diversity much but that was one of the reasons I bought the Sub Rx 
in the first place. With the 3 dB loss going to Diversity, I just listened 
more with the main receiver and let it go from there.

So today I'm working a ve7 on 10M and the band is going out. I can hear him 
but it's at that marginal iffy point, I was missing characters in his CW. I 
have a HI-Z triangular & a circle 8 pair of Rx antennas. The Circle 8 rocks 
on the low bands, has a filter to cut out above 40M but the triangular has 
no such filter and I often hear better on it than on the the roof mounted 
tribander. So for fun, I used diversity and the triangular on the sub,
160 sloper for the Tx antenna & Voil?, I heard him so much better, finished 
the Q and that reminded me of the real advantage of diversity and why it is 
an asset.

So now it's tonight, I see 3C0L is still on the air at around 3AM their 
time, on 20M. They're heading home today and the low band antenna is packed 
up already.
What troupers to still be in the game at this point. But I digress... So 
here they are, I don't have a good antenna for 20M, have to use the 160M 
antenna or tribander.
RFI from the neighbors makes the tribander useless so I hear them on the 
sloper and can hear them on the Hi-Z Triangular a bit better but much QSB so 
remembering the success with the VE7 earlier I go Diversity & all of a 
sudden, solid Q5 copy, no QSB and I snagged them on 20 CW.

Diversity really made the difference. I bought the K3s because it had such 
excellent specs, nothing else to me came close, save for 1-2 radios that in 
09 were hot and cost more than a new car. And they weren't any better in 
practicality than the K3 was. I bought the Sub Rx for the diversity and now 
today, while the K3s is itself stellar in all the right ways, it is an a 
better product with the Sub Rx.
I'm really honored to have such an
incredibly capable radio.

Just sayin'

Jan,

If you have the KPA100 and have operated it for more than 5 hours at 
greater than 50 watts, then the answer is YES, take the KPA100 off the 
base K2, remove the shield and tighten the PA mounting screws.  a 1/8 
turn is normally all that it takes.

here I hear A73A calling in the contest

I can't tell exactly where it is coming 
from but it seems like towards EU was 
strongest. 

It did not display on the P3 but the SVGA 
is much slower and shows longer capture 
and taking a photo of the the monitor, the 
print came out clearly. With the HI-Z 8 
Pro I was able to notch it almost 
completely out (95% out) but here's what 
it looks like. 

What are the children doing?

This may help readers understand what the energy can be like on a nearby antenna.  I was having a qso using my quarter wave inverted-L on 160 meters at 100 watts, and at the same time building a tuner.  I went to connect the  ladder line from my 80 meter loop that was not parallel to the L, but a wire from the loop crosses the L at 90 degrees about two feet above it at one point, otherwise nothing close.   I got an RF burn that had me yelling.  Not good separation, but I never considered the possibility of an RF burn with the separation I did have.

Many ops use the video feature of Fldigion some modes.? On one Navy MARS 
freq, when we changed modes, everyone TXing would post pre-video for a 
few transmissions.

When you switch from Thor to MFSK to etc, etc, etc. it is best to tell 
the other net ops what's up.? Conditions do change.? This is normal.

It looks like Digital SSTV.  There is a ?text? mode in a DRM SSTV app called Easypal (and maybe others), that sends brief text messages in the waterfall.

I?ve seen this show up from time to time, but was certainly curious the first time I saw text on my P3 screen :-)

Good Evening,
 ?? A very mild, dry week brought color changes to my elevation.? Lots 
of ferns turned gold and red with many other plants yellowing too.? I've 
done my best to modify the elk trails by clearing out dead trees.? They 
had better be patient because it will take another week to buck them all 
up.? With the forest becoming more open I should be able to see them 
more often.

The sun has a few tiny spots so we're dependent upon the solar wind to 
charge the ionosphere.? The forecasts predict them to increase on 
October 31 and again on November 9th & 10th.

Please join us tomorrow on:

Hello

is there any way to add more frequencies to the screen?

I can see center and edges freq but I want to see any scale, for example I
have 7000 - 7010- 7020, but I want to see the marks for 7001, 7002, 7003,
7004, 7005...........

Is this possible?

Also, you can search the pdf schematics- very convenient when tracing

As far as I can tell, no torque settings are given for any of the 
fasteners, wouldn't it be an idea to provide those, for people who do 
have suitable tools.  Generally there are just warnings not to over-tighten.

Almost the only time I don't use diversity is when I need the 
subreceiver for split pileup operations (and often it's enough just to 
watch the P3, so even then I use it). It can make a huge difference.
My antennas are only about 15m apart, but one is a dipole and the other 
a (vertically polarized) Pixel Loop.
The loop has a relay that disconnects it when I transmit so there's no 
danger to the subreceiver.

It is possible that an explicit torque has never been calculated.? It is 
not a particularly hard thing to do however.

I do not have a K2, so I can't do it, but here's the idea:

1) Fastener size/type, material, thread spec: (e.g. 4-40 x ___ pan head, 
phillips, zinc coated, non-rated steel
2) What does fastener anchor in?? (e.g. aluminum heat sink, what alloy 
aluminum, thickness of threaded area.
3) Thread spec... not JUST the #4, 40 tpi, but the rating for thread 
engagement.
4) Check the specs for the RF transistor.... package, et al.? Docs 
may/should have a max torque spec for the package.... maybe... package 
material, etc.
5) # of fasteners... usually 1 maybe 2.

There are tables that specify general torque specs for fasteners, 
threads in various materials, etc.... The idea is to take the lowest max 
value from the list.? This becomes the MAX NTE.
Then, use some analysis and judgement in what forces are to be imparted 
to the joint....? static tension, sheer, axial, radial, vibration, et al...
Then in this instance consider the qualities of the mating surfaces....? 
are the flat?? What is the run out?? Are they smooth? To what grit spec 
are they smooth?? There's a difference between flat and smooth.
What is the interface material being used?? Thermal pad? Insulating?? 
Non-insulating? Initial thickness? Read the spec sheet for the thermal 
pad/compound.

I suspect here that the RF package has an insulating thermal pad between 
it and the heatsink...? It was probably spec'd to keep the RF package 
within its operating envelope under 90% of expected operating 
conditions... knowing Elecraft, probably even a higher spec, and maybe a 
little extra to cover the "cheater".

Thermal pads and MANY top quality thermal compounds REQUIRE a curing 
period.? If the package is held with a tension spring/fastener, there is 
usually no requirement/need to re-torque.

IF it is JUST a screw and maybe a locknut, you NEED TO RETORQUE after a 
given number of thermal cycles....? The thermal interface material flows 
under heat and cools when not in use.? Eventually it reaches an equilibrium.
You torque the fastener JUST enough to hold the junction static at this 
point.? I'm a freak, I would use a thermally conducting thread 
locking/anti-seize compound (I made one).
I NEVER torque unlubricated fasteners.... ESPECIALLY steel to aluminum 
interfaces.

The final torque for this application is likely in the relatively low 
inch-pound range.... just guessing.? I have 2 inch-pound wrenches... 
0-15, and 0-70.? Most people don't....

Key... do NOT over-torque.? Consider the lever length and force applied...

Here is one reliable source for screw torque.

Without diversity I couldn't do my 144 and 432 MHz moonbouncing the way 
I do. It's perfect for Xpol's since I can decode both H and Vpol and the 
very same time. Thats a huge advantage against other rigs. Love it, a 
great feature.

Subject: [Elecraft] Tightening screws
Message-ID: <7AEE5063-ACB8-44F3-AB3F-B3781346E5D0@law.du.edu>


I can see the point of this for mass or machine-made production, but for a home-built kit there?s a simpler idea.  If the instruction is not to overtighten ? as for the screws holding plastic bezels in place ? I use a screwdriver with a smaller diameter handle. If the screw needs to be ferociously fastened, then a larger diameter handle.  The relative mechanical advantage could be calculated but probably not the actual torque ? that?s a function of muscle exertion and I don?t know how to calibrate that.  When the instruction says ?Do Not Overtighten? I just reach for a smaller tool.

    It is possible that an explicit torque has never been calculated.? It is 
    not a particularly hard thing to do however.
    
    I do not have a K2, so I can't do it, but here's the idea:
    
    1) Fastener size/type, material, thread spec: (e.g. 4-40 x ___ pan head, 
    phillips, zinc coated, non-rated steel
    2) What does fastener anchor in?? (e.g. aluminum heat sink, what alloy 
    aluminum, thickness of threaded area.
    3) Thread spec... not JUST the #4, 40 tpi, but the rating for thread 
    engagement.
    4) Check the specs for the RF transistor.... package, et al.? Docs 
    may/should have a max torque spec for the package.... maybe... package 
    material, etc.
    5) # of fasteners... usually 1 maybe 2.

When writing and validating the kit assembly procedures, I restrict myself
only to the basic hand tools recommended by the design engineers. The
objective is to avoid customers having to go out and buy additional tools
that are not really needed. If I find that I cannot do a particular step
with those tools I bring it up to Wayne and the other engineers who decide
on an alternative. Sometimes that is to require a new tool. For example, we
went through that over adding the requirement for a temperature-controlled,
ESD-safe soldering iron some years back. The K2 and other early kits had no
such requirement but as more sensitive components were used, Wayne specified
that we add it to the tools requirement.

On the other hand, there are times we have specifically said NOT to use a
special tool. A while back we had a lot of damaged parts because builders
were using electric screwdrivers that had no torque control or which had the
torque set too high, so Wayne had me say NOT to use them, preferring hand
pressure instead.

Actually we do provide torque spec's in one case; the mounting nut for the
transformer in the KPA500. That nut must work against a Belleville washer
that acts as a spring. The objective is to apply the right pressure to the
washer (55 inch pounds) without permanently deforming it. But, even in that
case, the engineers came up with a workable alternative to avoid builders
having to go out and buy a torque wrench.

As far as I can tell, no torque settings are given for any of the fasteners,
wouldn't it be an idea to provide those, for people who do have suitable
tools.  Generally there are just warnings not to over-tighten.

The "babies at play" are a group of SSTV operators who think they own a 
certain piece of 20M SSB. If you dare to call CQ there, even when it's 
empty and after asking if the frequency is in use, you'll be bombarded 
by their transmitters running as much power as they can, intentionally 
interfering with you.

I had only once before maybe a year ago 
seen what I thought were words on the SVGA 
and I thought someone went to long lengths 
to write software to QRM. 

If you look at the frequency on the 
monitor from the P3, this interference was 
7.065 or so and it was constantly being 
resent every minute or so.

The HI-Z circle 8 notched them out 
essentially completely. I aimed it towards 
them to have the words appear brightly for 
the photo. 

What a group of spoiled children. I 
haven't seen this intentional QRM before 
and had no idea what the P3 was revealing.

I just avoid 20M.? Problem solved.? There's other bands which respond as 
well with fine gentlemen operators, 17M and 30M as examples.? If you've 
not tried 60M, it is a wonderful relief from the vocabulary found on 40M.

The issue of who has priority on a given frequency was being debated 60 years ago when I first got on 75 meter AM.  It hasn?t changed.  It won?t change.  The language issue became a problem for me 20 years ago.  As a result I gave up phone and went to CW only, for the most part.  I also went to headphones because I couldn?t trust what might come out of the speaker when small children and my XYL were listening.  A very few obnoxious people ruin it for the vast majority.

I haven?t missed phone.

Agreed, those bands have nice ops. 160M, the gentleman's band, 
also deserves it's name. CW and digital are ways to avoid many 
of the (censored) ops. I have avoided voice on 80M because of 
the general lack of respect for other ops and the FCC regs. 
Perhaps I need to expand my list of bands to avoid using voice on.

This behavior has been going on as long as SSTV ... and 75M phone.

First thing to do is get on CW.  30M is a fine place to start.  I've been
CW (only) since 1951 and primarily on 40M.

Voice modes only require money and a mouth.  Jackasses usually need an
audience, and aren't likely to misbehave w/o one.

My only foray into SSB is SSB sweeps (nostalgia).  After that weekend I put
the mic away for another year.  That is all the SSB I can take for the year.
There are a few foul fist on CW but the wife and grandkids can't copy it so
I can safely leave the radio on speaker (until the wife tells me to "turn
that noise off" ;o(  ).  You would think after 50 + years she would have
learned to love it.

I can't even get that nostalgic!!  I only use SSB for the Ohio QSO Party,
and then the mic goes into hibernation for another year.  I find folks to be
much friendlier on CW and that's where I have been for nearly 40 now!!

the ones I can't figure out are the key  down and then sweep across the band 
with their VFO knob. I have bee seeing them since I had a soft rock pan 
display and now on the P3. They are almost continuous. they stop 
occasionally to QRM a QSO and then keep going.

I had only once before maybe a year ago
seen what I thought were words on the SVGA
and I thought someone went to long lengths
to write software to QRM.

If you look at the frequency on the
monitor from the P3, this interference was
7.065 or so and it was constantly being
resent every minute or so.

The HI-Z circle 8 notched them out
essentially completely. I aimed it towards
them to have the words appear brightly for
the photo.

What a group of spoiled children. I
haven't seen this intentional QRM before
and had no idea what the P3 was revealing.

Subject: [Elecraft] Using the KRC2 with the K144XV inside the K3s
Message-ID: <CAFyNi8614SvDnOaueK62PvuH2yhLGhuWt0W9QTJcvOSk_4uqZw@mail.gmail.com>

I?m using a KRC2 with a K3s to control transverters and a homebrewed band
switch system.  At present I have limited my drive needs to the 28 Mhz 0dB
and all has been well.



I?m considering adding transverters that utilize 144 Mhz drive and 0.1 to
1.0 watt drive level supplied by the K144XV internal 2 meter unit in my K3s.
I?m a little fuzzy whether the KRC2 will recognize an ?INT. TRN 0-9?
address through the Auxbus pin #2 of the K3s ACC (Accessory I/O) port and
provide the needed relay driver outputs.  The owner manuals of the KRC2 and
K3s are not clear.



Has anyone been through this?

Maybe "sweeping" for checking antenna SWR .... or "memory tuning'' of PA's
and antenna tuners, as Elecraft units do. (;-)

The frequency ownership is a farce of course.

I bet it was generated on April 1.  LOL

Regardless, RF know no boarders and it has no bearing over me even if it
was legal.

Perhaps a bit big for electronics work, but I?ve become a big fan of the
Borka adjustable torque wrench for mounting optics.

Bill,

I have not been through it, but in addition to the information on page 
41 of the manual, look at the menu listing for XVn ADR on page 68.

I interpret the information that the band data information for the 
internal and external addresses will be send over both the AUXBUS and 
output on the BAND DATA lines.
Back on page 21, there is a statement that INT TRN1-9 have the same 
decodes as TRN1-9.

Note the caution that TRN8 and TRN9 (also TRN0) will be sent as zero on 
the AUXBUS.

I think that also means you can only select 7 transverters with the 
signals on the AUXBUS.  If you need all 9, you will have to decode the 
BAND0 thru BAND3 outputs of the ACC connector.

73,
Don W3FPR

There are ionospheric chirp sweepers that go through the hf spectrum 
every couple of minutes. They sound like someone lightly clearing his 
throat. Have no idea what it looks like on the pan display. On a given 
frequency you'll hear the chirp at the exact same time every couple of 
minutes

Do a Google search for "Digisonde" for additional info.

There are hundreds of 'em.  They play an important role in the WWV

FWIW, I used to work at the University of Colorado's radio astronomy

Interesting.  These are RF peaks, that move across the 1.8 to 2 MHz band, 
for instance.  They often stop on QSOs in progress, or flow thru them, 
sometimes reverse, may disappear, may take off in either direction. I 
assumed they are human caused.  ???

While the OT CW ops on 160 still think it's the gentleman's band, a 
recent long thread on the Topband reflector has proved that to be dead 
wrong. The topic was the invasion of 160M by WSJT modes in the form of 
FT8. It doesn't seem to matter that the mode takes up only about 2 kHz, 
it's simply that it's not CW!

Bear in mind that these are guys who never call CQ, never answer a CQ 
unless it's a new entity, and many of them have some of the dirtiest CW 
rigs known to man. Far be it from them to respond to the weak CQ of a 
new CW op, who, after a few nights of this, gives up on the "gentleman's 
band."

By contrast, consider JT65 on 160M, which the "gentlemen" don't even 
know is there, but which on a typical evening last winter had 40 times 
more activity than CW (on a typical night, I rarely saw more than a 
single CW signal on my P3, and a few SSB ragchews. Except for occasional 
contests, CW on 160 is almost non-existent!

Last season, beginning in late Nov, I started monitoring JT65 on 160, 
hoping to work WV, SC, and VT, the last three states I need for CW QRP 
on that band. Within a few weeks, a sked yielded WV. Over the next few 
months, I let WSJT-X run all night and next morning, put the calls of 
all the stations I decoded into a spreadsheet. By the time I stopped 
doing that in early spring, I had logged more than 950 calls in all 
states except VT, most VE provinces, all continents except Antarctica, 
and about 20 countries. On a typical night I logged more than 50 stations.

The "gentlemen" most recently have gotten their tit in wringer about 
FT8. They feel that FT8 and JT65 devalues their 50+ years of DXCC 
chasing on the band, on CW, the only mode that real gentlemen operate, 
and ignoring the fact that some with the largest DXCC totals have 
achieved them by combining their operations from locations on the east 
coast and west of the Rockies. Earlier attempts to work RTTY on the band 
were pounded into oblivion.

The sweep I was referring to I've been hearing for years, anywhere 
between 2 thru 9 MHz. Never heard it higher than that, I think.

According to my notes last summer you could often hear the short chirp 
on 40m close to the ODD minute. It sounded like a raspy Morse "H". The 
sweep rate would accelerate from approx 50 kHz/s at the low end to 200 
kHz/s up near 8 MHz.

(I used to log all that kind of stuff as an SWL: "Giant Step, Giant 
Step, this is Retail. Do not Answer...")

I see a lot of sweepers, which are in reality Ionosonds.  The way to 
tell, is if they cover a very wide range, and they sweep at the same 
speed, they are probably probing the ionosphere.  There are a LOT of 
them sweeping the 40 meter band.

By asking for relays I was able to check in on the Elecraft Nets on both 20 and 40 meters today. I was unable to hear Kevin on 20 meters but could tell he was transmitting on 40 but his signal was at my noise lever (which is high}. Kevin must have a quite location because he was able to copy me running a 100 watts from my K3S. Thanks Kevin.

I too have been 99.5% CW for many years.  Two exceptions in this millennium were SSB skeds with Fred Cady, neither of which worked.

I know that anecdotes aren?t data, but I will share this one anyway.  Yesterday, having completed a K2 with the SSB option, I went on the air to see what people would say about the sound quality.  I didn?t know it until I got there, but this weekend is the CQWW SSB contest.  

When working CW and when my signal is weak at the station I am calling, the operator at the other end stays with it through as many repeats as it takes to complete the QSO.  I have often felt badly for everyone else in the pileup who is just waiting, silently, for their turn.  For that reason sometimes I decide to drop out and let someone else try.  That?s typical of CW in my experience.

The one near- SSB QSO I had yesterday, with a North American station, was very different.  After asking one repeat, having gotten half of my call right the first time, he just said ?negative copy, QRZ de WZNXXX.?  I tossed the MH2 on the floor.

Well, the K2 will still work on CW even with the SSB option.

Ted, KN1CBR

    The issue of who has priority on a given frequency was being debated 60 years ago when I first got on 75 meter AM.  It hasn?t changed.  It won?t change.  The language issue became a problem for me 20 years ago.  As a result I gave up phone and went to CW only, for the most part.  I also went to headphones because I couldn?t trust what might come out of the speaker when small children and my XYL were listening.  A very few obnoxious people ruin it for the vast majority.
    
    I haven?t missed phone.

Happy to relay you in, Marv. Yeah, you're a little close for both bands. I have the same problem on 20m. Most of the time Kevin is ESP here in northern CA on 20m. 

Yep Kevin has good ears. Sometimes he is plagued be QRN but even then usually pulls us through.

there's no 220v -yet. The operating environment is 100% cw with

Robert -

I have run my KPA500 at rated power for several years from nominal 120 volt
mains. I operate mostly CW with some RTTY as well. I have had many long CW
rag chews, but not much contest operation. My guess is that you should have
no problem.

I have been running at 120vac for years with no issues including RTTY.

I've run the 220 line to it, but haven't switched it over yet.

Kevin:

I have listened for several weeks and today was the first time that I could hear your transmission on either 20 or 40 meters. I am sure it is not your problem since I am using a vertical and have a very high local noise level. Yes, I live about 0.25 miles from the Pacific and elevation here is 6 feet.

I hope to improve the signal on 40 meters this week> I am going to be putting a terminated folded dipole with 90 feet of wire on each leg fed through a 9:1 balun and terminated with a 450 ohm noninductive resistor. I should be able to get the center up about 45 to 50 feet. If nothing else I hope it will improve the my noise where I can copy weaker signals. I sure hope so.

Thanks for your patience and hope to check it again.

Hi Marv,

     I was copying you between S3 and S7.  From what I could find on a map you live at or near sea level.  I live at 2000 feet which seems to be out problem.  The mountain I live on blocks a direct path between us so our only path is straight up and down.  I was just outside thinking about how to make an antenna which would be better for those folks who live in Washington & Oregon.  I have a doublet at 80 feet with one lobe pointing into Alaska and the other into the southeast.

     Thanks for the persistence.

          Kevin.

Robert,

The KPA500 will run OK on 110 (actually 115 or 120) volts.
The real question is how many other receptacles are on the same 120 volt 
circuit.  Are there any other large current drawing loads on that same 
circuit, and how much wire run from the breaker box to the receptacle 
being used.

Figuring an efficiency rating of 50% for the KPA500, the current draw 
for the KPA500 will be 9 or 10 amps.  The common receptacles are rated 
for 15 amps, and it depends on whether the wire size used is #14 (usual) 
or #12.  The smaller wire will have more voltage drop.
Electrical code requires #12 wire for kitchen outlets in modern 
buildings. But the remainder can be #14.
The other thing is that if the receptacles were wired using the 
"backstab" connections, that can create a higher resistance.  I would 
have an electrician check all receptacles on the circuit feeding the 
receptacle and change any receptacles using the 'backstab' connections 
to the lower resistance wires placed under the receptacle screws.

Since I had the advantage to wire my own house, I used #12 for all 
receptacles, and in the hamshack area, I have a dedicated circuit for 
the two receptacles there.  Most installations cannot boast of that same 
advantage.

I run on 240V at home, but at 120V from? a Honda 2000i on CQP and 7QP 
expeditions. Runs fine both ways, but on 120V, short runs of fat copper 
helps.

When CW came along, the spark operators said is was the end of amateur
radio as we know it.

When AM came along, the CW operators said it was the end of amateur
radio as we know it.

When SSB came along, the AM operators said it was the end of amateur
radio as we know it.

Plus ?a change . . .

Jim,

Same thing has happened on 2m eme.  The CW bunch debunk use of JT65 
for making contacts.  But it apparently is working so well that 95% 
of eme activity on 2m is digital with maybe two dozen CW operators 
left worldwide.  Before JT showed up in early 2000's eme activity was 
dropping off.  Now one can work 2m eme almost every day of the month 
with possibly 2,000+ stations worldwide.

It is 100% used on 6m-eme, and slowly gaining in popularity on higher bands.

For HF obviously digital is a small piece of the action, as it should 
be, since signals are frequently strong enough for CW or SSB.  But 
when prop drops the new digital modes will get thru.  With lower sun 
spot cycles forecast this will likely keep activity going when its 
difficult for CW/SSB.

Excellent articles in Oct. and Nov. QST explaining the various new 
digital modes.

As has happened every time a new mode gets a start there is the 
question of where in the band is best fits.  Time will sort that out.

I expect there will be much discussion on how the 630m band is used.

That'd be found at:-

??? http://www.maniaradio.it/en/bkttimesync.html

Looks good though not tried it myself.?? (Always try and get stuff like
that, from the author's own site, not from some arbitrary download page,
where it can have "other stuff" you definitely do not want, bundled with
the download.)

If using the network option, I'd suggest you use the address:-

??? pool.ntp.org??? (or??? north-america.pool.ntp.org???? in the US.)

As the target server.?? That will get you the nearest (network wise)
server to you.???? Keep well away from time.windows.com (or whatever) as
it is so congested as to be useless for these needs.


If you want your own local hardware NTP server, for example if your
internet connection is at all "flaky", or you're restricted to mobile or
satellite internet, or you have multiple PC's that need to stay in sync,
then see David Taylor's (GM8ARV) pages at:-

??? http://www.satsignal.eu/ntp/index.html

LOTS of good info and instructions there to do what you need, and mostly
for low cost, other than time to learn how to, and do it.


If you've $'s to spare and want something that "just works" out of the
box, then...

Not cheap, but very good.?? For those in RV's or afloat, best left
running 24/7?? Job Done.

If you have one of them in the shack at home, then you can contribute to
the NTP Pool project too, with care, but your internet connection may
get "hammered" as a result by incoming time requests.

Unfortunately, they were using it over the weekend and covering up some good DX 
working the SSB contest. They definitely weren't the only users of the band.

Don makes very good points here.?? Our hour built in 1979 is wired with 
#12 for all outlets and lights.? HOWEVER, the outlets and switches all 
used the"backstab" connections.?? In my efforts to resolve an issue, I 
found that several showed signs of heating.? Therefore, I replaced every 
outlet and switch.?? I used the "hook the wire around the screw" method 
and made sure everything was tight.

After doing so, I noticed my occasional light flicker was no longer 
present and my noise on the receiver was reduced.??? Radio wise, I ran a 
dedicated service, 240V, from the breaker panel to the operating 
position and a dedicated 120V service for a pair of duplex receptacles.

I strongly suggest you check yours or have a qualified and licensed 
electrician do so.?? It just might save your house from an electrical fire.

Radio wise, you can have the confidence you have a solid dedicated 
service for your equipment.?? By running almost any power amp from 240V, 
the line IR drop will be minimized, voltage regulation will be improved 
and IMD will be reduced as the result of your efforts.

Hi Ted

I had a bunch of guys call me yesterday who were zero point Canadian
stations, most I worked.  I just work them and dupes as it is easier just
to log them rather than explain why you don't want to work them.

However, the band was very crowded and very loud all weekend.  Sometimes it
is impossible to pull a signal out of the roar and that includes both high
and lower power stations.

I'm not sure if he sounded loud to you or not, however if he could have
copied you, he would have worked you even if it is a Zero point contact.

Don't take it personally.  The ether gods weren't on your side.  It
happened to me many times with the KPA500 on and the 3 element beam.

Folks - Thread closed. Both too many posts and the topic is outside of the list guidelines.

In general complaining about others and amateur radio policy discussions are inappropriate on the Elecraft list.  Also, they generate way too much volume for a single topic on the list and cause email overload for most of our readers. Please take these topics to other forums or to direct email.

Hi,

Are the schematics available for the KAT500? I am trying to resolve a
non-functioning Comm Port.

Best regards,

Message-ID: <CAHdU+vcskdyeYauU13Tu68AVPSi19Sc1DTqnHuQ-BZitOtnUnQ@mail.gmail.com>

While building the KPA500 I found that the ten mounting holes on the PA/LPF
module heatsink were not tapped deeply enough to accommodate the five 4-40
1/4" screws specified on page 22 of the assembly manual, nor the five 4-40
5/16" screws on page 24 of the manual.
I had to use the 4-40 3/16" screws in both cases.  If I had used the screw
lengths as the manual specified, the module would be loose and insecurely
fastened to both the Z-bracket and the right side panel.

Yes, I found this to be the case in one built a few months ago  Reported 
to ELECRAFT.

This has been a problem in the past too.  Used shorter screws.

Never got a response.

Yes, the KPA500 can be set up to run efficiently on 120 V vs 240. 

OTOH, as many have correctly noted, it will work much better with a
dedicated 20 A circuit using #12 AWG wire. Recognizing that, I figured it
was not much more trouble to put in a 240 V 20 A circuit with #12 wire (ok,
4 instead of 3 wires, per current code). If you have the space in your CB
box for the proper dual breaker, the effort is almost the same -- but you
get two benefits:

1. The voltage drop, and perhaps more importantly the change in voltage drop
from key up to key down, is about half -- much better for everybody, and
more peak output, if you're counting.

2. You now have the wiring in place for the KPA-1500, should you be so
inclined some day.

Have you checked the PC/MAC to trouble shoot?  Are you having difficulty with the utility for the KPA500?  There are a lot of steps to pursue before looking at the schematic of the interface in the KPA500.  First thing to check is to try the cable on a different working connection to make sure the cable isn't the problem, that can happen. To give further help a further explaination as to what you are seeing would be necessary.  You can always call Elecraft; they are extremely helpful.  I know, I have called in the past.

I agree with Joel on this.  I have a 220 socket, but ordered the 120 v model as I wanted to be prepared to move to another location where the 220 volt outlet wouldn't be possible.  I have had zero issues with the dedicated 120 outlet, also with 12 Ga. stranded, dedicated to 20A breaker.

Hello,

I was not a member of the K1 Field Test group, but I now have a K1 in 
the Field Test serial number range here for repair.

Is there anyone who can recall the changes made during the K1 Field Test 
or better yet, scan (or photograph) the RF board and marked up 
schematics that show the result of the Field Test changes - email them 
to me if you have that information.

This particular K1 has a lot of what appears to be "add on" components. 
I am not certain if those are the result of the Field Test changes or 
the result of further experiments by the prior owner.

Hi List,
my KX3 shows new behavior; dunno since when and what I could have touched.
here is what I do: Mode CW, SUB-RX on, send a dit or dah, go back to RX, 
now there is a tone in the audio path like a "pling" which is decreasing 
in volume within about 1.5-2 secs to zero. This seems to happen only if 
there is somebody sending CW on that frequency, it is not audible if 
there is just noise. All other settings (PRE;ATT,Filter BW) don't seem 
to make that tone go away. MCU 2.76, DSP1.5
Can anybody reproduce that?

The effect of the voltage drop is, of course, one fourth that at 120 V at the same power.

Message-ID: <781344A4-369A-4B39-9A7D-3B83D2A78641@elecraft.com>

I find that CW has many practical and engaging aspects that I just don?t get with computer-mediated modes like FT8. You?d think I?d be burned out on CW by now, over 45 years since I was first licensed, but no, I?m still doin? it :)

Yes, FT8 (etc.) is a no-brainer when, despite poor conditions, your goal is to log as many contacts as possible with as many states or countries as possible. It?s so streamlined and efficient that the whole process is readily automated. (If you haven?t read enough opinions on that, see "The mother of all FT8 threads? on QRZ.com, for example.)

But back to CW. Here?s why it works for me. YMMV.

CW feels personal and visceral, like driving a sports car rather than taking a cab. As with a sports car, there are risks. You can get clobbered by larger vehicles (QRM). Witness road range (?UP 2!?). Fall into a pothole (QSB). Be forced to drive through rain or snow (QRN). 

With CW, like other forms of human conversation, you can affect your own style. Make mistakes. Joke about it.

CW is a skill that bonds operators together across generations and nations. A language, more like pidgin than anything else, with abbreviations and historical constructs and imperialist oddities. A curious club anyone can join. (At age 60 and able to copy 50 WPM on a good day, I may qualify as a Nerd Mason of some modest order, worthless in any other domain but of value in a contest.)

With very simple equipment that anyone can build, such as a high-power single-transistor oscillator, you can transmit a CW signal. I had very little experience with electronics when I was 14 and built an oscillator that put out maybe 100 mW. Just twisted the leads of all those parts together and keyed the collector supply--a 9-volt battery. With this simple circuit on my desk, coupled to one guy wire of our TV antenna mast, I worked a station 150 miles away and was instantly hooked on building things. And on QRP. I?m sure the signal was key-clicky and had lots of harmonics. I?ve spent a lifetime making such things work better, but this is where it started. 

Going even further down the techno food chain, you can ?send? CW by whistling, flashing a lamp, tapping on someone?s leg under a table in civics class, or pounding a wrench on the inverted hull of an upside-down U.S. war vessel, as happened at Pearl Harbor. Last Saturday at an engineering club my son belongs to, a 9-year-old demonstrated an Arduino Uno flashing HELLO WORLD in Morse on an LED. The other kids were impressed, including my son, who promptly wrote a version that sends three independent Morse streams on three LEDs. A mini-pileup. His first program.

Finally, to do CW you don?t always need a computer, keyboard, mouse, monitor, or software. Such things are invaluable in our daily lives, but for me, shutting down everything but the radio is the high point of my day. The small display glows like a mystic portal into my personal oyster, the RF spectrum. Unless I crank up the power, there?s no fan noise. Tuning the knob slowly from the bottom end of the band segment to the top is a bit like fishing my favorite stream, Taylor Creek, which connects Fallen Leaf Lake to Lake Tahoe. Drag the line across the green, sunlit pool. See what hits. Big trout? DX. Small trout? Hey, it?s still a fish, and a QSO across town is still a QSO. Admire it, then throw it back in.

(BTW: You now know why the Elecraft K3, K3S, KX2, and KX3 all have built-in RTTY and PSK data modes that allow transmit via the keyer paddle and receive on the rig?s display. We decided to make these data modes conversational...like CW.)

Back to 40 meters....

I don't see this as an either/or. I've loved CW since 1955, and it's 
still my favorite mode. I'm a founding member of CWOPS (#69). I work SSB 
and RTTY to support my local contest club. I find WSJT-X modes another 
way to make contacts that I can't make on CW -- extremely weak signals 
under really lousy propagation conditions, meteor scatter, double- and 
triple-hop E-skip on 6M, and so on. I'm working on QRP WAS on 160, and 
am hoping that JT65, JT9, and FT8 will help me pick up the last two. All 
but those two and WV were worked on CW.

Wayne,

Thanks for this and for everything else you've done for CW, and 
especially for making good CW functionality an objective for all 
Elecraft rigs.

For me, nothing in amateur radio can possibly beat the thrill of hearing 
my own call in a weak and fluttery CW signal from the other side of the 
world. It's the same feeling I got 61 years ago when a guy across town 
answered my call for the first time.

Judging by the display on my P3, there is often more digital activity 
than CW these days. I've tried it and I'm impressed, but I'm impressed 
by what my smartphone can do, too.

My feeling is, "great, that is so cool, now back to REAL radio."

CW is special and I hope it will stay around for many more years, 
despite the technical "superiority" of other modes.

Message-ID: <201710310455.v9V4tbBS029393@mail46c28.carrierzone.com>

Have finished installing new synth boards (2) and the mods to the KBPF3.

Everything appears to work.  Downloaded 5.60 vers S from Elecraft.
HF and VHF working.  Haven't yet explored tuning below 500-KHz as the 
630m Inverted-L is not yet connected.

Spent about three hours of which one was spent on the filter.  0603 
chip caps take some patience; I elected to remove the old caps vs 
laying the new on piggyback.  I've found it harder than installing a 
cap direct to pcb.

Let the list know how it does on 630m.

Hi,

I checked my records of #00015, the first K1 on the air in Europe.
Unfortunately it seems I lost the field test documentation - we
communicated by email and I do not have backups.

I would also be happy to get the files to complete my documentation.

Best regards
Micha, DF4WX

Wayne,

Long time listener, first time caller...

Your words describing your journey and your passion have pulled me into the
iPad with this mornings? coffee...  Why?   Well, to begin with, we are of
approximately the same vintage, and had a similar starting experience to
this journey and passion..  my start at 13 was a 6AG7 / 6L6 with a single
FT243 (7008 kHz)  that I cobbled together in the cellar.

With a 300 ohm tv twin lead folded dipole nailed to the eve of our house at
the dizzy height of 14 feet, I made hundreds of contacts on  40 cw.  Damn,
it was fun...   so fun in fact, that I decided to get my license.   Yes,
you read it correct, and this is my public coming out of pirating when I
was 13, 42 years ago.   My sincere apologies to all those down the eastern
seaboard who didn?t get their C31BL card.   I picked Andorra cause it
seemed feasible where I was in the far north east of North America and
because it generated pileups with my pipsqueak signal....

Other than this passion, our paths diverged, and I still enjoy a career of
bringing innovation and learning technologies to large and small companies
around the world....

CW is, and always has been a huge passion, and though I?m certainly no
stranger to a microphone, your description of this club we belong to and
it?s unique window to it?s unique (and familiar to us) world, resonated.

I have other passions and interests, and in each of them there always seems
to be a writer that strikes a chord with me...   in cars and motorcycles,
it?s Peter Egan, in aviation it?s Lane Wallace or Richard Collins...

Your writing riveted me to the iPad and it felt like I was reading Ade
Weiss or Bob Locher, my two favorite amateur radio writers.   That?s pretty
good company to keep Wayne!

Please keep the passion strong, the innovation coming and please, please
continue to use the pen (and paddles) to share the gut felt visceral
excitement that cw and amateur radio are.

Thanks for making my morning.

Don Whitty

Great read and very well said, Wayne :) You brought back a memory of my sophomore year in high school back in the late 60's, still about 8 years away from getting my ham ticket. I was one of those "nerds" who was taking an electronics shop class. Our instructor was a ham operator. Aside from teaching us theory and circuit building projects, he taught us morse code. While other kids were learning Spanish and French, I and a handful of other nerds were learning this other"subversive" language that could be tapped out on our desk tops with a pencil during class. A few of us drove one English teacher crazy with our "code tapping"! Oh, eventually she got wise to what was going on. On test or quiz days, any one of us caught tapping our pencils on the desk, automatically failed!


Thanks for the story :)

CW has personality - therefore CW QSOs have personality. Digital not so 
much - press F3, F6, then to say 73s etc. press F9. Not much of a QSO to 
me.

Whether SSB, CW, RTTY, or whatever - it is all about rag chew to me. I 
cannot get excited about coming into the shack in the morning and 
looking at the computer screen to see who the computer QSOd with over 
night.

I miss the hours long RTTY gab fests on 40 meters many years ago. Sure 
we had our tapes, but we would keyboard all afternoon sometimes. Just 
cannot find that now. The art of gabbing has gone the way of the Tweet.

Just my take - that is what makes Ham radio so great. So many facets to 
keep us active.

Wayne,

Thank you so much for articulating the magic about CW.  I think we're of
similar age but I haven't been at for 45 years--just the last 12 or so. 
Some of my ham friends don't understand, and I haven't been able to
describe, why I prefer CW over other modes.  Manipulating the key to send
meaningful messages and learning to copy in my head are all skills I'm
continuing to build.  Your K1, K2, and K3 rigs--I have them all--are such a
joy to use on CW, and two of them I built.  Hearing my first call in CW on
the first CW contact was a joy I'll never forget.

The digital modes interest me only because of the difficulty (for me) in
integrating computer, radio, software, and antenna.  Pulling signals out of
the noise when they can't even be seen in the P3 is something I want to
conquer.  Not sure CW/digital is an either/or but a both/and.  Ham radio as
so many facets it's a shame to cast dispersions, as some do, on use of a
particular mode.

I guess the only thrill I'm missing after 160 countries on my handcrafted K2
using CW is putting you in my log.  Maybe someday...

Message-ID: <159593183.8802852.1509473878065@mail.yahoo.com>

I was wondering if anyone had tried doing the reference oscillator frequency calibration for a K2 without the rather troublesome step of accurate zero-beating by feeding the 500/600 Hz audio tones from WWV/WWVH to a computer sound card or smart phone spectrum analyzer, or similar program?  It's pretty easy to read these audio frequencies out to a precision of 1 Hz or so using Spectran or Spectrogram, for example. 

Right now, I'm seeing both WWV and WWVH tones (at the same time!) on my computer screen (within a few Hz of the correct audio frequencies), with the K2 tuned to 15000.24 kHz, so it really ought to be re-calibrated.

Are there any issues with this option, before I start into the whole process?

I'm comparatively young (41) but I appreciate the musings about CW.  I
still remember the first CW QSO I observed at a demonstration at a Red
Cross building in Michigan when I was 11 years old.  I'd had a pair of
plastic FM walkie talkies as a young child that had the dots and dashes of
Morse embossed onto the front, but I had not expected the thrill that I
felt as an actual CW QSO was made before my eyes. I was licensed a few
months later.

Another memorable CW QSO for me was the first time I sat in front of a
friend's K3.  The audio sounded so clear and beautiful that I soon ordered
my own.

I think there is something very special about the art form of CW and the
kind of craftsmanship and passion that it inspires.  Thanks to Wayne and
everyone at Elecraft, the CWOps, etc, for keeping the magic alive.

Matt NQ6N

The secret is in the way you approach it.  Method today is to learn the 
sound of a letter.  A is not dot dash or dit dah.  It is not Ah Pull. It 
is not ._    It is the sound of didah.  You repeat each letter until you 
have it down and move to the next one. This is called the Koch method.

The letters are sent at 20 wpm to reinforce they are one sound.  Code is 
sent slower by expanding the space between letters.  This is called 
Farnsworth method.

Here's a free trainer program  http://www.g4fon.net/

I learned Morse code the "wrong" way.  I had built a Knight-Kit Star 
Roamer, a very simple tube-type shortwave receiver that was mainly for 
AM reception but could "kind-of" receive CW.  In the back of the manual 
they had the Morse code written out in dots and dashes.

So I memorized a couple of letters (E and T since they were the 
simplest) and started listening.  Every once in awhile I could hear a 
letter that sounded like a single dot or dash, so I was pretty sure 
those were E and T.

Then I added a few more letters hoping to hear a complete word.  I think 
the first complete word I copied was "THE".  Then I added more and more 
characters (starting with the most common ones) until I had the complete 
alphabet, numbers and symbols.

One advantage of this method is you never get caught on a speed 
"plateau" because you are listening at full speed from the beginning.

When I was a Boy Scout and working on first class rank in 1965, you had to learn Morse, or Semaphore. Who wants to wave flags? So I memorized he code and passed first class. An assistant Scoutmaster who was a neighbor knew I was a broadcast station listener and showed up at he house one day with a cool looking old black receiver, a BC348 which he gave me
One day I was tuning around and found some really really slow code that I could sort of copy. I realized his wasn't commercial or military it was just guys talking! Mr sweet inform d they were Hams! I listened a LOT AND THE REST IS HISTORY!
I had a 15wpm sped before I even took my novice!

Steve,

That is exactly how I tune WWV before reading the VFO (TP1) and BFO 
(TP2) frequencies.  Adjust Control Board C22 until the 3 lower order 
digits match (since you are listening to a station known to be on a 
xx000.000 boundary the subtraction process is a snap.
You may want to LOC the VFO so the knob is not accidentally changed.

Additional information on my website www.w3fpr.com article on K2 Dial 
Calibration.

After doing CAL PLL and CAL FIL, go back to WWV and check the results. 
If you are within 20 Hz, that is about as good as you can expect.  The 
variation in BFO frequencies between filters in the K2 can be as much as 
20 Hz because of the resolution of the DAC.

73,
Don W3FPR

Matt!

Yes, this exactly. I'm not that much older than you are (44), and got licensed at 14. In spite of my best efforts, I fell in love with cw. I think a lot of y'all have articulated the why in a way I never could. I approached it as a socially awkward nerdy kid who knew that morse code wasn't cool in any way, but it was a necessary evil. Then I learned it wrong. After I got straightened out on that, it was magic. I took to it like the proverbial duck to water. 

Here's the funny thing. Wet up a ham radio demonstration. Play cw. Watch people come to see what it's all about. Do the same with voice. Watch people walk past. Digital, no clue how people react. But cw intrigues. Maybe it's because of the novelty. But it interests people. Oh sure, lots of the people it draws say I could lever learn that", and maybe that adds to the appeal? It's like this magic thing that not many people know. Like, hey, I'm the only guy on my block that knows this. But all I know for sure is that it's a whole lot of fun, and I hope that folks like you and me can help pass it on when all of those old farts? move on to that great big ol' radio ranch over yonder.

Wayne,

Add me to the chorus of CW and my thanks 
to the efforts of you, Eric & Elecraft for 
making such an excellent series of 
transceivers and mating components. I 
bought my Elecraft rig solely for the CW 
aspect, I wanted to hear the faintest 
signals I could possibly contact. 
Additionally, I liked that the company 
facilities are located in the states. I 
certainly buy from overseas, my CW paddle 
is a Begalli Sculpture, but I like that 
your company is here.

I did not come to CW easily, I learned it 
at 7 in the Cub Scouts and my father had 
been a ham since 1937 and coached me but I 
didn't get my ticket till I was 29. In 
less than a year from my Novice ticket I 
passed the Extra and have loved CW ever 
since. 

My first radio was a Kenwood 820S and it 
wasn't as good with CW as the Drake TR7 so 
I upgraded to that. The Corsair II was a 
better CW rig than the TR7 so I went 
TenTec. I liked the TT Omni 5 better than 
the Corsair II for CW so went with that. 
When I heard a K3 and read about the 
options I went Elecraft and bought a kit. 
Now I have the K3s. All the changes in 
radios because of my love for CW above all 
else in Ham Radio.

Thanks to all of you for your efforts. I 
look forward to the next Elecraft 
innovations.

73,

Gary

I agree with the below completely. Another 
excellent source is to tune into the 
ARRL's Code Transmissions on the air. They 
start at a fast speed and when finished, 
move to the next lower speed and so on. 
The advantage is you are trying to copy 
perfect CW sent faster than you can 
actually copy but you force yourself to 
listen harder, so you end up hearing more. 
When you get close to the speed you can 
copy, your head is already thinking CW 
better than usual and your comprehension 
is much better. 

http://www.arrl.org/code-transmissions

As it mentions in the link, the code is 
from QST and if you have the article in 
front of you, you can read it at the same 
time. I didn't find doing that was greatly 
helpful for me but another person might. 
The perfect CW and the slowing of the 
speed made the difference to me.

73,

Wayne,

Most appreciate your putting into words the elements and lure of CW.  The ham radio bug bit me in the late 1950s when a farmer in NE Montana (near our farm) happened to be a ham. He had a huge tower and beam and Hallicrafters receivers and transmitters. I was hooked and went on to get my 3rd Class Radiotelephone license and was able to work at our local FM station during high school. Following some college I went to a broadcast school in Minneapolis and ended up with my 1st Class Radiotelephone license and worked in broadcast radio for many years in Texas.

Finally got my novice and technician licenses over the years as well. Completed exams for Extra, but only did minimal on CW to get the ticket.

I've finally pushed myself to work CW as much as possible, but with my aging gray matter now it takes some time. I thoroughly enjoy CW and continue to struggle/learn better head-copy, but that just takes time and practice, practice and more practice.

Such a thrill to work CW even for a quick Q or a rag chew and now that I'm mostly retired I'm able to continue my learnin' of CW.

Great posting Wayne and thanks to you and everyone at Elecraft for simply excellent rigs.

YES!
 Well said Wayne.

I have always loved CW from being a small boy with an old straight key and
buzzer, learned Morse before I knew of amateur radio.

Short Wave Wireless will never lose its fascination for me and
to communicate via the ionosphere with another by Morse code is the
ultimate thrill.

Today, despite having all the best equipment to hand together with computer
assistance internet and all the latest gadgets and aids.

The original concept of visualising the remote OP hand on key, sending a
signal, 'instantaneously' arriving in my receiver is still magic, and to
hear your own call come back to you in CW just can't be bettered.

Of course, I do appreciate all the modern digital modes, I get them
working, try them but then rapidly lose interest and return to CW, the
personal mode requiring some degree of aptitude, perseverence, and skill to
be part of the club and call yourself a CW OP.

Still 'just a boy and his radio'

I learnt CW the old way around 1962: starting at slow speed, but I believe that is not the best way. Recently a local club I belong to (most of the guys are fm/repeater types, but a few are interested in reviving/building their CW skills) asked me to think about a possible CW training program. I searched, and found the CWOPS CW Academy. I was very impressed! However, I found their website a bit confusing, so I dug further. I have found out: They are a club with membership fees, but you don't need to be a member to take the training. (In fact, you can't become a member unless you are already good at CW.) Their beginner classes work the same whether the student had learnt CW in the past or is a complete beginner, and I get the impression that the success rate would be about the same for both kinds of student. They run only 3 beginner classes per year, recruited from all over the world, and the number of students admitted per class is quite small. It appears that there is a waiting list of a year or so. When you are already hesitant, that wait has to discourage you a bit, and so would the need to align your schedule to their start date. I contacted the organization and asked if I (not a member of CWOPS) would be allowed to teach the beginner class, using the CWOPS method and training materials to local students, at a time of their choice. The answer was yes! I didn't ask whether any prospective CW teacher would be allowed to do this, but if you know your CW at better than 20 WPM, I think it very likely that CWOPS would approve your request to teach using their materials. So, if you are a student interested in learning CW the CWOPS way, but don't want to wait for a the CWOPS official class, maybe you could find somebody local to lead a CWOPS type class for you and a few friends, assuming that that person would get approval and training materials from CWOPS. As to my running such a class, I am not sure that my club will actually go forward with it, but it seems like a good idea if the prospective students are eager to learn.

CWOPS CW Academy...  Learn by hearing.  Don't EVER use a chart. If YOU doo your part, you can be head copying 25 wpm in what I consider a very short time.

I'm not there yet (just finished Level 1), but I'm headed thataway!

Early on in my ham radio experience I also struggled with the ability to copy cw.

I finally decided to devote 30 minutes each and every day to listening to code on the air. Many days it would have been easier to go to bed and forget the allocated 30 minutes but I could easily see the improvement in my ability to copy cw. 

For about 1 year I kept a sked with a former Navy code instructor. He was a big jokester and would send jokes on the air  but would not repeat the punch line. Frustrating yes but it made you listen closely.

I still can't copy 50 wpm and at 80 years old I doubt if I ever will but 30 to 35 wpm is not a bad. What ever the speed it is enjoyable.

I for one am lucky enough to have in the log.

Three unanswerable questions:? "What is the meaning of life?";? "Are 
there hams in other star systems?"; "What is the secret to learning 
Morse code?", and, if 50 people answer your question [likely a low 
estimate], you will get 62.87 answers. [:-)

The "secret" really is ... there is no "secret."? There as many 
effective ways as there are aspiring CW operators.? Not every method 
works for everyone.? Here's a partial short-list of things to investigate:

1.? CW Academy, operated by the CWOps group? cwops.org

2.? Download Morsegen [http://www.g4ilo.com/morsegen.html].? It will 
send to you in a variety of modes, including text from a file

3.? Make audio files from Morsegen, write them to a USB stick or CD's, 
and "read" them while on the way to work or a long trip

4.? Send to yourself.? Put the K3s in TEST mode

5.? Listen to W1AW practice and bulletin sessions [1]

6.? Listen to CW contests [2]

7.? Have "in-room QSO's" with K3s in TEST with a friend

8.? Put a Morse ringtone on your fone.? Mine sends the name, if in my 
fone book, or the number if not, for calls and SMS.? You may not get 
much practice unless you get a lot of calls/texts but it sure gets 
attention in the checkout line at Home Depot. [:-)

9.? Put your K3s in TX NORM mode and start making Q's at a speed you're 
comfortable with.? I hear a number of 5 WPM CQ's in the afternoons on 20 
around 14050.

Note:? There is a vast difference between verbatim copy and "head 
copy."? In a normal QSO, the probability is 0.9964 that the only 
elements you'll hear will be RST, Name, QTH, Rig, Antenna, Wx, and "WL 
TNX QSO GUD DX CUL 73."? The only one you really need to jot down is 
name.? The only time verbatim copy is needed is in traffic handling.

73,

Fred ["Skip"] K6DGW
Sparks NV DM09dn

[1] A potential issue with the W1AW at increasing speeds is that one can 
become obsessive over one's current speed.? One needs to forget about 
speed, yours is what it is and it will increase.

[2] Speeds in contests will range around 30-35 WPM.? However, all that 
is being sent is call signs and some very small amount of "data" such as 
5NN 3 [fake signal report and CQ zone #].? In the Wed CWT's it's a name 
[all short] and 1-4 digit member #, and knowing what's coming next will 
improve your copy ability and speed dramatically.

Message-ID: <1509483005232-0.post@n2.nabble.com>

Hi there,
Currently have my K3, P3, Steppir controller and PC working flawlessly via
the RS232 out on the K3 to the P3 then the Y cable to the Steppir and the
PC. Steppir follows logging program as does the K3 etc.
I just bought a Acom 600s and am not clear on how to best work it into my
connections so I get the auto band switching. I don't really want to use the
RF sensing method through the antenna cable.
Can the ACC port on the K3 be used to control the amp? I don't have anything
connected to that ACC port.
Thanks for any help!
Alan

Thanks.

My problem is that I live out in the country so far that there won't be 
broadband for the rest of my life and probably the life of my 
grandchildren.? I have satelite internet which is fine, but I can not do 
skype, so CWOPs is out.

Alan,

Not having that amplifier, I cannot give you a positive answer, but I 
can tell you how to determine if the BAND DATA outputs of the ACC 
connector will band switch the amplifier.

What you need to look for is "band decoder" or something similar in the 
amp manual.  There may even be a chart of which codes will activate 
which bands.  Compare that with the chart of the coding on the BAND 0-3 
outputs of the ACC pins.  If they match, then all you have to do is make 
up a cable to send the right bits to the amplifier.

73,

The N6TV Acc port devices work great.? Allow 4 attachements to the ACC 
15 pin lines and much much more.

Hi all,

Have just recorded 2 messages using my KX3. Both played back well. However, I wanted to chain message 1 and 2 but have not been successful. When playing message 1 in repeat mode and then pressing #2 button the display shows ?Chain? but messages stop altogether.

All help appreciated

Alan,

Another answer along with a bit more data and a caution - IF the amp is 
capable of listening on the RS-232 connection for band information, add 
another "Y" cable between your current "Y" cable and the PC and the amp 
should be able to use that data.

Caution, if the amp uses full RS-232 communication (both send and 
listen), that will interfere with your current setup.  BUT if the amp 
only 'listens' to the information on the RS-232 interface, all will work 
well.

In other words, an RS-232 connection can have only one set of drivers. 
Multiple devices can 'listen in' to the traffic on the receive line with 
no problem.

Jeremy,

I don't do Nabble, so I don't know about that 10 year old post.
What is your problem with your 2T-Gen?
Note that this is one of the 2 Elecraft products that use a hyphen in 
the model designation!  The N-Gen is the other one.

Hi Don,

I have the 700Hz tone, but not the 1900Hz.  Here is the quote from the original post.  I measured similar voltages.  I?ve also included your response to him.  It seems like a pretty simple device, and I?ve double checked the components and soldering.  My 12 year old daughter did most of the soldering, so the only thing I can think of is her leaving the heat on too long and damaging a component, but there are no burn marks on the circuit board.

The 700 Hz generator works and produces a max 150 mVolt peak signal, but the 
1.900 Hz generator does not work. I noticed that Base of 2N3904-Q1 (1.900 
Hz) shows 0 V, while Base of 2N3904-Q3 (700 Hz) shows 2,1 mV. With a 8.9 
Volts Vcc, Collector Q1 shows 8,1 Volts while Collector Q3 shows 6.7 Volts. 
Drains Q2 and Q4 (2N7000) show both 4.4 V (= Vcc/2). The voltages of pins 
1,2,3,5,6,7 of U1 (LMC6482) are all 4.4 Volts. Replacing Q1 with an 
available spare didn't help and didn't change the voltages. 

  

With the scope, I get a 689 Hz sinusoidal signal on U1 pin 7 (570 mV peak), 
but nothing on U1 - pin 1. 

There is a "saw teeth" signal on collector Q3, nothing on collector Q1. 


Raymond, 

I believe the oscillator should oscillate even with Q1 removed.  Look 
carefully at the feedback loop around U1A particularly C2, C4, R1, R2 
and R6.  Be certain the jumper blocks are in the 'T' position. 

The most likely problem is soldering or a misplaced component.  Use a 
magnifier to check for any tiny slivers of solder between adjacent pins. 

73 and good luck with it, 
Don W3FPR 


Thanks,
Jeremy

Jeremy,

What is the voltage at the gate of Q2?? And what is the voltage at the 
drain?
Those two points should control the level of the 1900Hz tone.

Likely possibility is that Q2 was damaged by static when installed.

You should have the JP2 jumper set for the "T" position.

In my post about setting up the CWOPS training outside of the organization, I omitted the following. When discussing the idea with a CWOPS representative, I said some of our presumptive participants might not be able to do Skype. I suggested that we instead use an FM net over a repeater. I was told that that would be just fine. In your case, if you are not in range of a suitable FM communications, I assume HF SSB would be fine as long as you select the frequency and time to produce solid communications for all participants.

My problem is that I live out in the country so far that there won't be broadband for the rest of my life and probably the life of my grandchildren.  I have satelite internet which is fine, but I can not do skype, so CWOPs is out.

Hi Wayne

A few years ago I was in a hotel in Sanford, FL for recurrent aircraft
training.  It was actually hovering around 32F.

I was awakened in the middle of the night by some banging on the wall from
my hotel neighbor, and figured a party was going on and went back to
sleep.  Some time later I again heard the banging, but this time it was a
distinct SOS.  Not having any idea of what might be going on, I called the
front desk (3 AM) and informed them that someone might be in trouble
because of the SOS.

A short time later there was fire equipment outside, but no obvious fire or
other reason for concern.

When I checked out after breakfast, I inquired about what had happened
earlier.  The clerk asked if I was the guest who had called  to report the
trouble.  When I answered in the affirmative, she explained that my
neighbor was in the military and knew how to sound SOS and he wanted to
extend his thanks for saving him.

So what had happened?  This guy had stepped out onto his balcony to have a
smoke.  As he closed the sliding door, the latch snapped closed and he was
trapped outside, stark naked, in cold weather.  The front desk clerk went
to his room, but he had closed the safety bar to prevent any intrusion and
the hinges weren't accessible from the outside.  So the fire department was
called and brought him down with a ladder (and hopefully in a blanket).
The hotel had to put him up an an empty room, since his was inaccessible.
The next morning the maintenance crew used their ladder to get inside and
open the door so he could get his belongings.

Morals of the story:  1.  You never know when knowing Morse Code can really
make a difference.  2.  Don't ever smoke naked outside

	The main & I mean main thing is desire. If learning CW is a job or
task you'll probably drop out eventually. In my 57yr.s on CW that's
what I've heard most often. It's too hard, it takes too long or I can
never learn it.

	When you learned to ride a bike, get your drivers license or met your
mate it was something you really wanted. The desire was there. 

	It's only 26 letters, 10 numbers & a few other symbols. You probably
have more PC passwords with a mix of numbers & letters and characters
than what CW requires. Bet you know the passwords by heart.

	My Dad [SK W4YAD] passed his 13 WPM code test at age 55 after a mild
stroke. He saw me on CW & wanted to learn. That ole' desire again.

	Try what ever method to learn that you are comfortable with. If you
can find a partner that's much better. I was lucky that at age 13 my
best friend & me learned together. We talked in Morse. It was our
secret language. He became K9UFO [SK].

	Another motivation you might consider is CW is another language. You
can become bilingual ! Just as playing music or speaking Spanish is a
different language you will have a new world to explore. A language
only spoken by people with that desire.

	Desire is everything!

I find that CW has many practical and engaging aspects that I just don?t get with computer-mediated modes like FT8. You?d think I?d be burned out on CW by now, over 45 years since I was first licensed, but no, I?m still doin? it :)

Yes, FT8 (etc.) is a no-brainer when, despite poor conditions, your goal is to log as many contacts as possible with as many states or countries as possible. It?s so streamlined and efficient that the whole process is readily automated. (If you haven?t read enough opinions on that, see "The mother of all FT8 threads? on QRZ.com, for example.)

But back to CW. Here?s why it works for me. YMMV.

CW feels personal and visceral, like driving a sports car rather than taking a cab. As with a sports car, there are risks. You can get clobbered by larger vehicles (QRM). Witness road range (?UP 2!?). Fall into a pothole (QSB). Be forced to drive through rain or snow (QRN). 

With CW, like other forms of human conversation, you can affect your own style. Make mistakes. Joke about it.

CW is a skill that bonds operators together across generations and nations. A language, more like pidgin than anything else, with abbreviations and historical constructs and imperialist oddities. A curious club anyone can join. (At age 60 and able to copy 50 WPM on a good day, I may qualify as a Nerd Mason of some modest order, worthless in any other domain but of value in a contest.)

With very simple equipment that anyone can build, such as a high-power single-transistor oscillator, you can transmit a CW signal. I had very little experience with electronics when I was 14 and built an oscillator that put out maybe 100 mW. Just twisted the leads of all those parts together and keyed the collector supply--a 9-volt battery. With this simple circuit on my desk, coupled to one guy wire of our TV antenna mast, I worked a station 150 miles away and was instantly hooked on building things. And on QRP. I?m sure the signal was key-clicky and had lots of harmonics. I?ve spent a lifetime making such things work better, but this is where it started. 

Going even further down the techno food chain, you can ?send? CW by whistling, flashing a lamp, tapping on someone?s leg under a table in civics class, or pounding a wrench on the inverted hull of an upside-down U.S. war vessel, as happened at Pearl Harbor. Last Saturday at an engineering club my son belongs to, a 9-year-old demonstrated an Arduino Uno flashing HELLO WORLD in Morse on an LED. The other kids were impressed, including my son, who promptly wrote a version that sends three independent Morse streams on three LEDs. A mini-pileup. His first program.

Finally, to do CW you don?t always need a computer, keyboard, mouse, monitor, or software. Such things are invaluable in our daily lives, but for me, shutting down everything but the radio is the high point of my day. The small display glows like a mystic portal into my personal oyster, the RF spectrum. Unless I crank up the power, there?s no fan noise. Tuning the knob slowly from the bottom end of the band segment to the top is a bit like fishing my favorite stream, Taylor Creek, which connects Fallen Leaf Lake to Lake Tahoe. Drag the line across the green, sunlit pool. See what hits. Big trout? DX. Small trout? Hey, it?s still a fish, and a QSO across town is still a QSO. Admire it, then throw it back in.

(BTW: You now know why the Elecraft K3, K3S, KX2, and KX3 all have built-in RTTY and PSK data modes that allow transmit via the keyer paddle and receive on the rig?s display. We decided to make these data modes conversational...like CW.)

Back to 40 meters....

What I tell new hams is to learn characters with s high dot rate ( e.g.15-20wpm) but with a low character rate e.g.5 won that way you learn the "sound" of the character and will
Move faster quicker. The way I got to 25 was to
Copy in my head by visualizing a blackboard and placing the character on that. Eventually you hear the sounds of common words( like your call sign)

For me, CW doesn't really have much romance.  Not big on SSB either.

My favorite time may have been with a model 15 on autostart.

Had a lot of fun with a TAPR Beta TNC too.

I never argue against those who love CW.  I just want a few KC's 
somewhere for my favorite mode(s).

I started in ham radio as a Novice in 1959.? That required 5 WPM, 
crystal control, 75 watts and only CW.?? Finally up to 13 WPM and a 
General license and later to an Extra class license which I hold 
today.??? Over the 58 years that are now behind me,? I drifted away from 
CW to a much easier SSB mode.? Now at 75 years of age I find the mind is 
not nearly as sharp, as keen and as fast as it was 50 or so years 
ago.??? In order to stimulate the thinking process, hopefully in an 
effort to delay dementia and other mind altering age related issues, 
I've returned to CW.??? I'm being reminded of my H.S. math teacher when 
asked "why do we study algebra?", he responded "It's mental gymnastic 
training". That's the way I view and approach CW today.

Subject: [Elecraft] On Digital
Message-ID: <r470Ps-10126i-540FB21984D7460BA7A445A8778D6092@Williams-MacBook-Pro.local>

I took a somewhat different path from Wayne, and as a result 
fell in love with the digital modes.

I started as an electronics nerd in junior and senior high 
school. I loved building electronics projects, especially kits.

There was a radio club in high school which encouraged me to get 
my novice ticket. I still remember sometime in 1960, getting on 
the Long Island Railroad to ride into Manhatten to take my test 
at the FCC office. I had ridden the train into New York many 
times before, but this time I turned way downtown instead of 
uptown where I had gone on all previous trips. I arrived at the 
FCC office more than a little bit scared. I managed to pass both 
the written and code tests, and anxiously waited for my ticket 
to arrive in the mail. When it did I was WV2NOO.

I rounded up SX-99 receiver and a Heathkit 40W transmitter kit, 
and then I hit a serious snag. I am dyslexic and have a great 
deal of difficulty with written English. However, CW QSOs are in 
written English with a big does of CW OP jargon. The jargon I 
could handle, but I could not get a string of letters to become 
a word at any speed. Even now, I need to write them down before 
I can recognize which word they represent. My novice year went 
by with almost no QSOs.

Fast forward to the year 2000, 40 years later. Somewhere about 
1975 I had learned to write English, although I was and am a 
slave to spell checkers. My software startup has just gone 
bankrupt. I was at loose ends and said to myself, "I'll study up 
and get a no-code tech ticket. I have caving friends who use the 
WA6BAI repeater in Kings Canyon National Park to communicate. I 
can join them."

I studied the ARRL book and took the test. I aced the test and 
the examiner said, "Why don't you take the general test, it 
won't cost you anything." So I took the general test cold and 
passed. I walked out with a database entry that became KG6JOH 
and a piece of paper that said in essence, "Learn 5 WPM CW in 
the next year and you can have a general."

I had learned 5 WPM 40 years earlier and figured I could do it 
again. So I got the CW CDs and learned the code. At the same 
time I studied for the extra exam because I wanted to stop 
having to jump through hoops and just be a ham. Within the year 
I had passed both exams and became AE6JV. But I still wasn't 
doing very much on the air. I was one of those hams that build 
equipment but rarely use it.


I joined the West Valley Amateur Radio Association (WVARA) 
because the West Valley is where I live and I wanted to support 
at least one open repeater to give back to the hobby and "pay" 
for the open repeaters I used with my caving buddies.

WVARA takes Field Day very seriously. As a new member, I went up 
to the site and saw the CW tent, the 3 SSB tents, and the 
digital tent. I was invited into the CW tent to do some 
operating. I declined because learning 5 WPM for the test 
doesn't mean you can make it in the real world. I did a bit of 
operating in a SSB tent, and then Phil, W6PK who was in charge 
of the digital tent, invited me to do some PSK31 operating. I 
had found my niche. PSK31 was like the computer chat rooms I had 
supported in my last job. Typing I can do with my eyes closed 
and the incoming words appeared in print, so I could read them 
the way I read books, papers, etc.

I look back at my log and see the first 3 years as exclusively 
PSK31 contacts. Then I branched out to RTTY for the North 
American QSO Party. Finally in March 2013 I decide to try to 
contact TX5K on Clipperton Island. On 15M I managed both a SSB 
contact, and my first CW contact. I was decoding the CW both by 
partially ear and partially with the K3. I was sending from the 
K3's memory. After listening to my call many times in the 
pileup, I could recognize it when TX5K came back with it and 
press the other button to send the exchange.

Six months later, my log shows what I described as my first CW 
QSO with Al, W6SQQ in Orange, CA. The log shows he was using a 
K3 with a G5RV and had nice cool weather. I am sure I copied all 
that by typing it into my computer and reading the screen. The 
log from that time shows many digital contacts and a scattering 
of SSB and almost no CW. Then came the W1AW portable operations. 
I was hooked on contacting the W1AWs, and I made many more CW 
contacts, but these were certainly not rag chewing. They were as 
mechanical as the digital contacts when the operators just play 
macros at each other.

These days, when I operate CW, I am either contesting or DXing. 
In either case, the vocabulary is small enough that I can 
recognize the words -- CQ TU 5NN ? -- without having to think 
about the letters. If I need to think about the letters, I still 
use a computer to change them into words, eliminating many of 
the real advantages CW has. I can use a straight key, but slow 
down alarmingly when confronted with a paddle.

Somewhere along the line, I managed to earn a DXCC and a Grand 
Slam WAS -- WAS on CW, digital, voice. I still consider digital 
to be my "home" mode. I have had many enjoyable rag chews on 
PSK31, particularly with Michael, VE3NOO and Mary, KC9TIE.

As and example, today I got a LotW acknowledgment for a FT8 QSO 
with Jim, ZL1LC. My log shows two other QSOs with him on PSK31. 
It also notes that he operates from Waiheke Island, Oneroa with 
a Icom 707 and a Cushcraft vertical. I don't know if we got away 
from the macros, but certainly exchanged more that signal 
reports and grid squares in those QSOs.

I will continue to struggle with CW and be happy that there are 
so many modes people can use. Almost anyone can find something 
that works for them.

Subject: [Elecraft] Have AF control both the Main & SUB volume
Message-ID: <59F92EB0.29755.174DD2@Gary.ka1j.com>

I'm trying to set up the K3s to have both 
the sub and main controlled by the AF knob 
and not finding what I had done before.

Looking at the manual under CONFIG:SQ MAIN 
it says:

SUB RF gain normally sets the sub 
receiver?s RF GAIN level. If this knob is 
assigned to main/sub squelch (CONFIG:SQ 
MAIN), then RF gain for main/sub is 
controlled by the main RF gain control.

When I go to CONFIG:SQ MAIN and select via 
VFO A it offers numbers ranging from 1-29 
and then it says =Sub Pot With two options 
of SQ MAIN and SQL N/A which defaults back 
to SQ MAIN.

None of the above locks the volume of the 
Sub to the Main like I had it set on the 
K3, AF still controls the main and SUB 
controls the SUB volume.

I am missing the obvious. 

Suggestions?

Thanks & 73,

Gary

My first house - 1968 - was one that was newly built.  I had the
opportunity to run a 50A 240V feeder from a breaker on the main panel to
a sub-panel in what was my ham shack after I did the load calculation to
ensure that the main had the capacity to serve the sub-panel as per
code.  Installed dedicated 120V and 240V branches with quality
receptacles.  We stayed there 9 years until we needed a larger place,
but I never was able to do that again.

Jeremy,

Those voltages seem to be OK.

I have obtained information from Elecraft support that C2 may be the 
problem.
The capacitor may be too low in value.
Replace C2 with a .01uF capacitor and see if that fixes the 1900kHz 
oscillator.

It seems like a pretty simple device, and I?ve double checked the components and soldering.  My 12 year old daughter did most of the soldering, so the only thing I can think of is her leaving the heat on too long and damaging a component, but there are no burn marks on the circuit board.
