Subject: [FreeBay] Swap Ameco preamp for audio filter.
Message-ID: <20021001.194442.-486879.3.ko6bb@juno.com>

Hello.

This is a repost as it turned out the previous unit offered had problems.
 I'm 'NOT' particularly interested in selling this unit separatly, at
least at the moment.

I have an Ameco model PCL "Nuvistor" Preamp.  For those not familiar with
it, this unit uses 2 Nuvistors (submini tubes) instead of transistors. 
It seems (and what I've read confirms) that it outperforms the newer
solid state preamps as it is quieter and less overload prone.  These tune
1.8 to 54 MHz and really perk up an older receiver, especially on 6
Meters!
 
This unit has two NEW Nuvistors installed and works well. It is in VERY
good cosmetic condition as the copper face is shiny with NO corrosion. 
It gets it's power (6.3VAC and 125-250 VDC B+) from the receiver it is
used with and is presently wired with an 8 pin octal plug to fit a
Hallicrafters SX-71.  If you need it I can assemble a small power supply
to run it, though it wouldn't be pretty. It is getting difficult to find
these in good condition and the Nuvistors are almost always bad when you
do find one.
 
What I need.
 
I need a good Audio CW filter and prefer one that has better than 100Hz
selectivity and adjustable frequency at least from 400Hz to 800 Hz. 
Either analog OR DSP are fine (NO Radio Shack DSP's).  Should drive a
speaker as well as headphones)  MUST be in good condition, especially
elctrically.
 
Units I would take in trade.
1.  Autek QF-1A (MUST be "A" model).
2.  Timewave units.
3.  Some MFJ and Vectronics units.
4.  Some Heathkit units.

Subject: [FreeBay] Swap Marconi Lab Signal Generator for DSP
Message-ID: <20021003.002959.-338565.3.ko6bb@juno.com>

Hello.
I have a Marconi laboratory type Signal Generator that I'm willing to
swap for a DSP CW audio filter.  I prefer the Timewave DSP-59+, MFJ-784B
(MUST be B model) or DSP-9+ in that order but will consider others such
as some of the NIR etc.  MUST have good sharp CW selectivity (100Hz or
better) and be in good condition.

What I have.
Marconi Signal Generator Model TF2016A.
ALL solid state, no "boatanchor" here.
Frequency Range: 10kHz to 120 MHz in 12 ranges.  
Tuning controls:
     1.  Slide rule dial.
     2.  Carrier Range Switch (12 ranges).
     3.  Tune Control.
     4.  Fine tune control.
     3.  Extra Fine tune (10 turn) control
Modulation types:  
     1.  CW.
     2.  AM, 0-100%
     3.  FM, variable, full scale dev. settings of 5, 25 & 75kHz.
Modulation: Internal 400 & 1000 Hz & external input up to 100kHz.
Output Level: Up to 2 Volts. Range .2uV to 2 Volts.
Output leveling for constant output level. 
Attenuators:  Internal 120dB in 10db steps and variable 10dB.
Outputs:
       1.  BNC RF output on front panel.
       2.  BNC Internal Mod out (400 & 1000 Hz) on back.
       3.  "Counter" output on back (High level RF output)
Inputs:  
       1.  BNC External Mod In on back panel.
       2.  BNC Sync/Sweep in on back panel (can be used as sweep gen).
       3.  24-32VDC input (for battery operation)
       4.  115/230 VAC input.
Size:  WHD  11 x 5 1/2 x 11 inches.
Weight: About 15 pounds.       

COSMETICS:  Front panel "very nice", Top and side covers show wear. 
Can't send pictures but I can scan a page from the manual.

This unit operates as it should, is stable after short warmup and is
suitable for alignment/troubleshooting of AM,SSB, CW and FM (narrow or
wide) receivers.

Shipping etc:
For a Timewave DSP-59+ or MFJ-784B "I" will pay the shipping/packing
costs.  For other units I may need some "help" with shipping costs
depending on what you have to offer.

I am in need of a power pack for my old laptop computer.  It would
appear as though it has gotten lost.

The computer is a Toshiba and required an 18vdc power pack.  If
you have one you would part with, please reply off-list to:
nn7b@gbis.com

Thanks!

Subject: [FreeBay] Swap MEchanical filter and Xtals for 455.8 KC Xtal
Message-ID: <001901c28073$1959b8e0$35c47643@ko6bb>

Hello.
I've run into a snag on building my Longwave CW receiver.  I have an IF
bandwidth of under 400Hz and an audio bandwidth (800Hz) of 70 to 400 Hz.  My
problem is the only BFO crystals I have are 456.5 & 453.5 kHz (designed for
use with a 2kHz mechanical filter).  I've tried padding them down with
various inductors and capacitors but they refuse to "rubber" more than a
couple hundred Hz before they quit oscillating.  Guess they were designed to
be stable at their operating frequency!  I even tried a 455KC Xtal but it
"zero beat" my IF almost perfectly.  No 800 Hz "tone" there!

I NEED a crystal whose center frequency is about 455.8 to 455.9kHz.  It
would be BEST if it were in a HC-6/U or CR-45/U plugin  housing but at this
point I really don't care! I will solder it into the circuit or change
sockets if need be.

WHAT I WILL SWAP FOR IT: (3 items)
1. Kokusai Electric mechanical filter, -6dB at 2KC, -60dB at 60KC. On small
board WITH matching transformers.
2. 456.5KC Xtal with HC-6/U socket.
3. 453.5KC Xtal with HC-6/U socket.
These Xtals are "mated" to the Mechanical filter as they came out of the
same set.  Should make a nice SSB adapter (product detector) for a BA that
doesn't "DO" SSB so well.

I'd like to get this set "up and running" before the winter Longwave DX
season runs out <G>.

Message-ID: <002701c28081$af00d8c0$38c47643@ko6bb>

Hello.
I have two 72 pin SIMM sticks of Hewlet Packard 8MB 60NS EDO DRAM that I
will mail to anyone who NEEDS it for their operating computer.  Lots of old
'pooters as "second or logging" machines in hamshacks are shy on memory.
This was pulled from a Hewlet Packard Pentium 200 machine when it was
upgraded.

Hopefully somebody can use it, if you just want it to "throw in the bag"
with your other old memory, heck, I can do that 8^)

If anyone has an old CB radio laying around in their closet and would like to 
see it put to good use, please email me. I am looking for donations of 23 or 
40 channel radios and antennas for a local community watch group.

Thanks!
