[Elecraft] K3 ERR TXG

[Rowland]

Hi Ron .
No I did not have any synthesiser error messages at any stage.
I thought that may have gone out of lock as tuning the main dial alterd 
the background noises but not that much ie tuning seemed slower than 
expected.
As I said in the mail to the list I should have scanned the RX freq with 
my sig gen that may have given a clue as to what was happening

Perhaps you need to run Cal Syn after a retro fit of the KPA3 but it is 
not documented anywhere I can see
Thanks
Rowland

Do you have any error messages when running the Synthesizer calibration?

If the synthesizer is out of lock, the receiver will still produce some
noise and possibly what sounds like signals. But it'll be way off 
frequency,
which would explain the inability to transmit.

Thanks to those people who replied to me off list with regard to the ERR 
TXG problem

Having checked out my dummy load and all connections to the K3 I could 
find no problem.

Trying to set the TX config for the PA was OK on all bands apart from 10MHz
When going back to receive the 10Mhz band sounded odd, no cw sations 
heard that were there prior to testing,
changing bands down to 7Mhz and then back to 10Mhz restorednormal 
recieve with CW staions audible.
Again trying to check for 50W out the rig would then show a varying 
output and the SWR varying.
Recieve again was odd. The main tuning seemed to vary the frequency but 
what that frequency was I dont know.

I should have checked with the signal generator in retrospect.

I decided to re do Cal Syn and since doing this the rig seems to be 
working as described with no problems on 10Mhz receive or transmit.

Thanks to those who replied to my request for help.
