Mark,

While you may be correct about the TMP connectors, open the K3 and rotate the TMP connectors a bit to wipe away any oxidation.

If it continues to fail after that, email supp...@elecraft.com for further ideas on how to proceed. Tell them what you have attempted so far.

Interesting

Powered up radio again and worked fine again.  Within minutes failed again so I 
am suspecting the tmp connectors as suggested by K1XX (and others) and the SYM 
area.

Yesterday while just listening to a SSB QSO, the receiver just went quiet and 
when I tried to transmit, got nothing.

Power setting was at 75 watts and varied properly but meter and external output 
monitor was showing nothing.

Thought the filters stopped passing RF.

Rechecked the filter settings on the Utility program and all seemed normal (no 
change).

What could cause the radio to behave like this? During receive?

Regards,

Mark, K1RX
