Thanks for getting back to me. I finally got some sense out of Kenwod UK and they confirmed the build date as 1998.

It's a step up from my TS-850SAT, performs really well.

Looks like a TS-570 predecessor in terms of functionality.

I'd be interested in seeing a map of Kenwood transceiver development history. Does something like this exist? Maybe even an article on same?

That's a lot of radio!

I will pull the top cover off and look for that adjustment pot. Thanks.

Adjust VR1 in the radio.

I have reports that transmission is low or soft. How do I increase the Mic gain on these radios?

I bought my 870 new a long time ago and it’s my main hf rig. You won’t be disappointed, I’m sure.

Thanks Trevor, and a Happy New Year to you too.

That information appears on a number of web sites, including this one:

https://chat.qth.com/viewtopic.php?t=2822

It was the note about some sets with a 00 number being manufacturer refurbs from later years that made me curious. The set I bought looks like it's never been out of its box.

My TS-820 receives fine for a few minuts then the S meter pins and the audio is mute ?
Any ideas ?

Hi Mike
I found this years ago but can't remember where it came from...

TS870S first figure of the serial numbers linked to year of manufacture as follows:

This is how it works:
7 = 1995
8 = 1996
9 = 1997
0 = 1998
1 = 1999
2 = 2000
3 = 2001
4 = 2002
5 = 2003
6 = 2004

73 and Happy New Year

Hello I am including the link to Rigpix TS 930

My 930s died. All DC voltages ok. Turn on, relays chatter, S meter lights, no frequency display. The service manuals on line have no schematic. Anyone have one?

Hi everyone

I've just bought this radio in mint condition from a dealer and would like to know its year of manufacture. I contacted Kenwood support in the UK but they referred me back to the dealer, who is unable to help.

The SN is 00100062. I found a source that said it's either 1999 or a factory refurb sold in 2002 or 2003.

Anyone able to decode this for me please?

Hello

Has anyone put an external automatic antenna tuner on a 940S?? If so, what make and model.

Thanks,

John

I am realigning my TS-50 and I’m having difficulty adjusting the miniature IF transformers on the TX-RX board.
?The cans are about 1/4 inch square. ?The adjustable core appears to have a square or rectangle shaped hole. ?A photo is attached. ?I suspect other Kenwood radios also use this transformer.

?I have a good assortment of alignment tools but nothing small enough to fit. ?The best I have been able to do is file down a spare nylon alignment tool. ?It sort of works.

Can anyone identify the correct tool?

Microphone, Signal Generator, Cables,
Misc Parts, Manuals, and more For Sale

.

Kenwood MC-43 Hand Microphone:

The Kenwood MC-43 is the standard hand
microphone used with many, many Kenwood
rigs. It has a round 8 pin connector and will
work with most any Kenwood rig that takes
this connector.

The top of the mic has up/down buttons to
change the frequency.

This one works as it should, and looks very
close to new. It has not been around smoke.

With paper work for only $45

.

Lafayette TE-22 Audio Generator:

The TE-22 is a sine/square wave audio generator.
It dates back to the mid-1960s, and possibly was
OEM'd for Lafayette by Trio KENWOOD. Circuit
wise it is a Wein Bridge oscillator like the HP
200 series, but instead of a lightbulb, it uses a
thermistor as the nonlinear feedback element.

It covers from 20 Hz to 200 KHz in four bands,
and produces up to 7 V output.

This one looks like it just came out of box from
the factory. No scratches or defects of any
sort! Pristine! It produces a signal when
displayed on my scope. The wave form is not
perfect, but is quite acceptable.

Buy this unit with manual for $50

.

Linear Amp Switching Cables for Kenwood Rigs:

This cable goes from a Kenwood transceiver to a linear
amplifier to switch the amp from transmit to receive.

One end has a DIN connector, as is used with most Kenwood
rigs. The other end has an RCA phono plug, as used by most
linear amplifiers.

Before using this cable, please check the switching
capabilities of your transceiver, and the requirements
of your amplifier.

Cable for switching the T/R relay Only $15.

Cable with ALC control, in addition to T/R switching. $20
