[Elecraft] k3 no RF in transmit

[Joseph McIntire]

I have tried test mode everything looks  normal  in test mode. When not in test tried with wsjt-x through a signal link as I had been using it for months on 1o,12,15,17,20,and 40 meters. I was using it and everything was fine. Until about 10:00 yesterday.  Checked so cables between te radio and amp. Then I realized I did not have even the  drive to the amp. Absolutely 0 watts. I was driving the amp with about  8 watts. Then I decided to make sure nothing external was affecting the radio so I disconnected everything except  power and antenna  cable to wattmeter and dummy. Still zero. When you depress the XMIT button on the radio it switches automatically to CW and transmits a carrier normally.  It switches to cw but still no RF out . Displays dashes for SWR and 0 watts. Hooked a mike up changed settings.  I can see the ALC change but still nothing  out. Tried high power a day low so it is in the  drive     I believe as the 100 watt amp is the same results as the 10 watt.

Just to cover the bases, make sure you're not in transmit test mode.
