Low RX and Zedro Watts output after KIO3 board substitution

[Elecraft mailing list]

Hi
My K3 (s/n 3871) experiments low RX and 0W output (when pressing the TUNE button) with -- as SWR measureNo SSB or CW output power
It hapenned after I substituted the original KIO3 board by a spare one I bought to a ham (the aim was to solve an ols no speaker audio aout problem)
I have the KXV3 installed at the factory
Any idea?
Thanks in advance  Marcel, EA3IN

Marcel,

Double check the plugging of the connectors between the RF board and the
KIO3 board.  Unfortunately, you will have to disassemble things to be
able to see the mating of the connectors.

And, I suspect your no speaker out problem isn’t with the KIO3 board at all. It’s likely the audio speaker amp and it on a board in the front panel.
