[Elecraft] K4 TX Problems

[Will Hrachovina K4MI]

I recently received my K4 SN #153 a couple days ago. I transferred all the antennas, microphones, and CW keys over from my K3 but have run into a few problems.

First, I have tried transmitting in CW but cannot get the radio to transmit anything. I have tried two sets of paddles and ensured I plugged it into the correct jack. I also tried a straight key in the Key jack and the same issue presents itself. I also ensured VOX is on. Even if I manually activate transmit there is nothing transmitted. It has me thinking the Jack’s may not be turned on.

I have similar issues with the PTT jack behind the radio. The switch I plugged into the jack is not activating the transmitter. I did ensure it was plugged in correctly.

Finally, I have another issue with the front panel mic jack. I can key the radio from it, but the microphone I plugged in is not working. I checked and the front panel microphone is enabled in the settings. I have a CM500 plugged in to the rear of the radio and it does work when switched to rear input.

Has anyone else run into something like this? I’m concerned there are settings I am not enabling that are causing this issue. The accessories in question worked fine on my K3 before I changed radios.
