Is there anyone left who still services the TS-820S?

I have one in storage with the speaker and external VFO, which has some 
"issues", I have no time to deal with it at this point, and my sweet 
understanding wife want me to begin getting rid of my surplus equipment 
before either of us kicks off.

When I used the rig, I really liked it. The last time was about a year ago or 
so.

Recommendations?

All,

This is my first post. I have a strange issue with my kenwood ts-940SAT.
Here is the issue:
My radio receives and transmits very well. The issue is that my S meter
barely works. If a really strong signal comes in the needle spikes and then
slowly descends. If the signal is not really strong the needle does not
move. 
When I transmit the needle works without issue in all settings (power, swr,
acl and so on).  I have all the knobs set per the operating manual for first
use. I am stumped at this issue.

Thank you for reading this issue and all comments or suggestions are
welcome.

Hi,
same "problem" here with my TS-940, one of the latest serial numbers, 9 Millionxxx. My S-meter moves only when signals are stronger than S5-S6.Some typical TS-940? issues are :- S-meter scale is calibrated according to Japanese scale, where S1 japanese = S5 in the? Collins USA signal scale.- there is a PIN diode attenuator, in RF board,? exactly after the RX input filters, before the RF cascode FET amplifier,? that could be out of calibration: the reference value is adjusted by VR1 in RF board. See service manual for the right values
- the input attenuator relays could have dirty contacts
Last, but not least, if your radio is very old, it could be necessary to check the whole RF-IF signal chain. The Service Manual is of help.
Just try this : switch to lower band, 500KHz - 1.5 MHz: if? the received signals or noise level is strong, and the S-meter goes to S6 or beyond, this means that the at least the signal chain is OK, otherwise it needs to be services.Hope this helpes73MarioIZ0IRH

Easiest way to check is turn on the internal calibrator. It is after the
attenuator relays and leaves them out as a problem. It should read S7-9 on
a properly aligned radio on 20m @ 14.2 in USB. If that is correct and an on
air signal is way low then the attenuator relays need to be replaced. If
it's not S-7-9 a signal calibrated output generator is needed to determine
if the problem is s-meter setting or the rx sensitivity is actually down
due to a problem.

As a note the 940's were aligned to the Collins spec, 50uv = S-9, FWIW S-1
= 1.25uv. The levels in the service manual are different because the SG
output is speced into an open load not 50 ohm.

Thanks a lot Clif for clarifying and the suggestion to use the internal calibrator. According to your experience is it possible to find a replacement for the attenuator relays? Mines sometimes give the 10 dB step as 20 dB or nothing.BR

It is in the Owner's Manual.

Look at page 6.

On the top of the TS-940 is a sliding cover.

Slide it to the side, and the Cal switch is on the right hand side.

It is labeled CAL, with ON and OFF positions.

Thank you for the information. I did the ?internal Calibrator? test per your
instructions and it read S9. May I ask another question? On page 50 of the
users guide. Section 11-2 adjustments 1 and 2. Where do I put the leads of
my volt meter to test the voltage? I looked in the service manual and it was
still vague. 

Thank you very much for your help. I really appreciate it.

Easiest way to check is turn on the internal calibrator. It is after the
attenuator relays and leaves them out as a problem. It should read S7-9 on a
properly aligned radio on 20m @ 14.2 in USB. If that is correct and an on
air signal is way low then the attenuator relays need to be replaced. If
it's not S-7-9 a signal calibrated output generator is needed to determine
if the problem is s-meter setting or the rx sensitivity is actually down due
to a problem.

As a note the 940's were aligned to the Collins spec, 50uv = S-9, FWIW S-1 =
1.25uv. The levels in the service manual are different because the SG output
is speced into an open load not 50 ohm.

It's labeled RB and in the first set of instructions for alignment.

Might I suggest you not adjust anything, it's working. A lot of the
adjustments require test equipment beyond most home shops. Some of the
adjustments seem benign enough like the AGC voltage setting. But when you
adjust the AGC voltage you have to recalibrate the S-Meter. The service
manual expects you to start on Pg 1 and go thru every step in order. A lot
of steps affect steps on down the page so you can't jump around. If you
want to go thru and take notes on the different readings in each step
without adjusting anything that's OK.

First Rule: "If it ain't broke, don't fix it"

This might be a long shot, but I am looking for a Kenwood TM451A 70cm radio
to use on the satellites.

I would also consider a Kenwood TM251A 2m with 70cm receive for the right
price. or another UHF FM rig.

Let me know the price shipping to Lawton, OK (zip 73507).

I can pay with paypal, check, or MO.

Kenwood and related Items For Sale:

Microphones, Original Boxes, HT Accessories,
Noise Filters, Original Manuals, and more


Kenwood MC-48 DTMF Touch Tone Microphone
Used on most Kenwood rigs with round 8 pin mic plug.
Includes up/down switches as well as the 16 digit tone
pad. Excellent, close to new, condition. $40


Hand Microphone with round 8 pin plug for Kenwood, Alinco, etc.

This hand mic works great on most Kenwood rigs with the
round 8 pin connector, such as the TS-430, TS-440, TM-241,
TM-2530, TW-4000, and others, including Alinco and ADI.
It says "Electret Condenser Mic" on the back, and
"Kenwood" on the front, with no model number.

Basically, this mic functions like an MC-43, with a couple
more features. It has the mic and PTT switch; it also has
up/down switches on the top. There are four "extra" buttons
labeled Call, VFO, MR, and PF. What these four buttons do
depends on the rig. There is also a "Lock" switch on the back.

Regardless if you use the four extra buttons or not, you
still have a mic that works like an MC-43.

This mic works fine, and looks like new. I am guessing it
came with a rig, and was immediately put in the drawer,
and never used. $30

If you're lucky it is not the relays but rather the solder connections to the relay coils. Reflow the solder and see if anything changes.

I'm guessing you are referring to the method used for the TS430. Don't do
that on any radio but the 430. You will damage the 140.

And just curious as to what this would be the case?

Why would it not damage the 430 but would something else, what make the 
430 different?

Just wondering,

Do any of you know the serial number range of TS 2000 transceivers that had factory defects or less than desirable characteristics in the filters and OR final transistors and or final amplifier boards in the Kenwood TS 2000 transceivers?
I just acquired one in the 803XXXXX serial number range. Haven't used it yet and would like to know more about the problematic serial number ranges before I use it. Please share your knowledge with me. Thanks and 73, John, K5PGW?

GD,

Looking for advise on a dead (actually two) TS-850sat.   One died during the WPX rtty contest with 10 minutes to go.   Gave a couple of fades (display panel died out) then completely died.

A friend gave me another TS-850s that he had picked up, but it was dead from the get-go.  Thought this was strange so swapped out the power supply and power cable but no go.   Other equipment on the power supply work fine.

Appreciate any pointers.

Thanks.  Chuck N7BV

GE,

My TS-850 decided to die with 10min?s left in the RTTY contest this weekend.  

It gave several like power downs before dying.  Swapped out the unit for a spare TS-850sat and the same results so replaced the power supply and power cable between the power supply and TS-850, but still the same results - it won?t turn on.

Any suggestions.

Thanks.  Chuck N7BV

Hi,this evening I replaced the two attenuator relays that are in the RF unit with two OMRON units as suggested by Clif, and the problem was completely gone! As new life for my TS-940. (So I decided to replace also the third relay, RL3, of the same type. )
It was not necessary to replace the TX/RX reed relay.Thanks to Clif for the precious suggestions.73MarioIZ0IRH (KK6GYP)

It's labeled RB and in the first set of instructions for alignment.

Might I suggest you not adjust anything, it's working. A lot of the adjustments require test equipment beyond most home shops. Some of the adjustments seem benign enough like the AGC voltage setting. But when you adjust the AGC voltage you have to recalibrate the S-Meter. The service manual expects you to start on Pg 1 and go thru every step in order. A lot of steps affect steps on down the page so you can't jump around. If you want to go thru and take notes on the different readings in each step without adjusting anything that's OK.

First Rule: "If it ain't broke, don't fix it"

Clif,
Thank you for the information. I did the ?internal Calibrator? test per your instructions and it read S9. May I ask another question? On page 50 of the users guide. Section 11-2 adjustments 1 and 2. Where do I put the leads of my volt meter to test the voltage? I looked in the service manual and it was still vague.?
Thank you very much for your help. I really appreciate it.?

Easiest way to check is turn on the internal calibrator. It is after the attenuator relays and leaves them out as a problem. It should read S7-9 on a properly aligned radio on 20m @ 14.2 in USB. If that is correct and an on air signal is way low then the attenuator relays need to be replaced. If it's not S-7-9 a signal calibrated output generator is needed to determine if the problem is s-meter setting or the rx sensitivity is actually down due to a problem.

As a note the 940's were aligned to the Collins spec, 50uv = S-9, FWIW S-1 = 1.25uv. The levels in the service manual are different because the SG output is speced into an open load not 50 ohm.

Hi,
same "problem" here with my TS-940, one of the latest serial numbers, 9 Millionxxx. My S-meter moves only when signals are stronger than S5-S6.Some typical TS-940? issues are :- S-meter scale is calibrated according to Japanese scale, where S1 japanese = S5 in the? Collins USA signal scale.- there is a PIN diode attenuator, in RF board,? exactly after the RX input filters, before the RF cascode FET amplifier,? that could be out of calibration: the reference value is adjusted by VR1 in RF board. See service manual for the right values
- the input attenuator relays could have dirty contacts
Last, but not least, if your radio is very old, it could be necessary to check the whole RF-IF signal chain. The Service Manual is of help.
Just try this : switch to lower band, 500KHz - 1.5 MHz: if? the received signals or noise level is strong, and the S-meter goes to S6 or beyond, this means that the at least the signal chain is OK, otherwise it needs to be services.Hope this helpes73MarioIZ0IRH

?Oggetto: [Kenwood] Kenwood TS-940SAT S Meter

All,

This is my first post. I have a strange issue with my kenwood ts-940SAT.
Here is the issue:
My radio receives and transmits very well. The issue is that my S meter
barely works. If a really strong signal comes in the needle spikes and then
slowly descends. If the signal is not really strong the needle does not
move.
When I transmit the needle works without issue in all settings (power, swr,
acl and so on).? I have all the knobs set per the operating manual for first
use. I am stumped at this issue.

Thank you for reading this issue and all comments or suggestions are
welcome.

Kenwood Items For Sale:

Monitor Scope, Microphones, Original Boxes, HT Accessories,
Original Manuals, and more


Kenwood SM-220 Monitor Scope, with BS-8 Pan Adapter

The Kenwood SM-220 Station Monitor is a multi-function monitor
scope which functions as a band-scope since it includes the BS-8
pan display option, monitor and tone generator. It is the ideal
product for supporting, monitoring and calibrating equipment.
It can be used to observe SSB distortion, CW key clicks, and
test linearity of linear amplifiers. It has four sweep ranges
and also can serve as a RTTY tuning scope. Frequency range:
1.8-150 MHz. Maximum Power:  2000W 1.8-54 MHz and 100W 150 MHz.

Features:
   Bandscope ? 100 kHz (with optional BS-8)
   10 MHz Oscilloscope
   Matches many Kenwood Transceivers
   Wideband Transmission Monitor
   RTTY X-Y Tuning Meter
   Built-in 1000/1575 Hz Two-Tone Generator

Cosmetically, this one looks like new.  I can not find a scratch
on it, and all lettering is nice and crisp.  Electrically, it
works fine.  The intensity varies as it should, the focus does
as it should, and when I connect a signal generator to it, the
sine wave looks like a sine wave.  I have no TS-820 or TS-830
to confirm that the BS-8 works, but I am fairly certain it is
fine, since other parts of it are fine.  $350


Kenwood MC-48 DTMF Touch Tone Microphone
Used on most Kenwood rigs with round 8 pin mic plug.
Includes up/down switches as well as the 16 digit tone
pad. Excellent, close to new, condition. $40


Hand Microphone with round 8 pin plug for Kenwood, Alinco, etc.

This hand mic works great on most Kenwood rigs with the
round 8 pin connector, such as the TS-430, TS-440, TM-241,
TM-2530, TW-4000, and others, including Alinco and ADI.
It says "Electret Condenser Mic" on the back, and
"Kenwood" on the front, with no model number.

Basically, this mic functions like an MC-43, with a couple
more features. It has the mic and PTT switch; it also has
up/down switches on the top. There are four "extra" buttons
labeled Call, VFO, MR, and PF. What these four buttons do
depends on the rig. There is also a "Lock" switch on the back.

Regardless if you use the four extra buttons or not, you
still have a mic that works like an MC-43.

This mic works fine, and looks like new. I am guessing it
came with a rig, and was immediately put in the drawer,
and never used. $30
