Re: No TX #ubitx

Hi Joe, 
I'm experiencing similar symptoms as captured here: https://groups.io/g/BITX20/topic/7878333?p=Created,,,20,1,40,0 

Current draw indicates that it's making power, but nothing is making it to the antenna. FWIW, my initial bias current was 380 mA. 
 
I validated with a separate receiver that the radio is transmitting. I had concluded that K3 was bad; replaced it tonight (it did measure with open coils), but still no output.  

Tomorrow, I'll follow Ashhar's suggestions in this thread to check around the toroids and I'll run some DC checks on the relay paths.
