No Receive or Transmit.

[Stuart]

I have just switched on my K3 for the CW-T activity to find I have no receive or transmit. The radio was working fine last night, no problems at all

I have tried the EE INIT and reloading firmware to no effect.

Any help would be appreciated

Have you tried restoring your configuration? With all the lightning we've
had recently, maybe the memory got zapped?

When you say no receive, do you mean absolutely no audio or just no signals?
Wrong antenna selected? Do you appear to generate RF when you attempt to
Tune?

I recently switched on our club's K3 after performing some major upgrades,
including SMD components. There was no receive audio and after the initial
panic subsided, I realised that I had inadvertently turned the RF gain to
zero. Is that a possibility with yours as well as possibly having the TX in
Test mode or the power turned right down?

Hi Alan,
              Thank you for your reply.

I tried a reset and reloading configuration but this did nothing, followed
by a sinking feeling in my stomach!

I have various transceivers and antennas coupled by switches, and as you can
imagine, I sometimes get the combination wrong, but this was not the case
this time.

The radio did not receive anything, just a background hiss, but no signals
at all. I transmitted into a dummy load via a power meter and this showed no
output.

Research on the internet suggested checking the TMP connectors on and around
the synthesiser board, but this did not help.

Next I refitted the original synthesiser board, and now the radio seems
fine, suggesting the KSYN3A is faulty.

I have had a reply from Matthew, VK5ZM,who had a similar problem, and this
was caused by the LO not running, but I think that only applies if the 2m
module is fitted. I will investigate and let you know how I got on.

Thanks again,
                        Stuart, GD0OUD.
