K3 Sub Receiver problem with KSYN3A

Hello,

My Dad picked up a K3 that is a late number 9xxx it had a sub receiver and
both synthesizers are the KSYN3A. A little history on the rig first,
Original owner bought as 100 watt kit and installed the sub receiver. Second
owner installed a couple filters on the main board and the antenna tuner
KAT3 and my Dad got from him. Anyway, my Dad and I were going through it and
could not get anything out of the sub receiver, set speakers to 1 and now we
get static so that's a good sign.

Figured it was the settings so checked KRX3 and set it to Ant-BNC and hooked
up to the AUX BNC to the signal generator. Went through setup with K3
Support from Elecraft and still nothing. Checked all connections on sub
receiver and noticed that the Green LED on the sub KSYN3A was not lit like
on the main receiver KSYN3A. Swapped them and appears that the problem is on
the board because now I have a green light on the sub (originally main) and
nothing on the main (originally sub). Went to check syn status and it showed
PLL instead of SYN1 OK and SYN2 OK. No receive on main or sub.

I put them back the original way and main works but no sub Status says SYN1
OK and SYN 2 OK but no green LED light on the sub board. I ordered a new
KSYN3A for the sub so hope that works but still have no idea why no green
LED but says SYN2 OK.

Any thoughts on my long winded comment?

73,

Jeff

Re: K3 Sub Receiver problem with KSYN3A

I hope that you worked that problem through with Elecraft Tech Support on
the phone, particularly since there's the cost of a KSYN3A involved. Some
troubles have so much stuff floating around to sort through that it's just
plain difficult to work it via email.

Re: K3 Sub Receiver problem with KSYN3A

I worked it with Howard from Elecraft and everything points to the board but also wanted to run it through here to see if anyone else had a problem like that. My K3 is an older one with the older Synthesizer boards so I can’t do any “swaptronix” with the boards.

Re: K3 Sub Receiver problem with KSYN3A

Thanks for the reply, I hope that it's the board, that way I can send in the "broke" one and see if they can fix it cheaper than a new one. That way I would be halfway to getting my K3 updated hi hi.

Anyway I got My dad's set up for him and he is tickled to have a good rig for CW. He'll just use RIT for DX and he is good with that for now.

73,
Jeff

Jeff, not sure if anyone answered your real question, but yes have seen several posts about the new Synth board stop working, and a couple not working from the factory, same problem as you have, no green light etc.
Seems to be some are having the problems, not many but a few.
