Everyone. I need your input. Looking at the HpT20 schematic below: I have key down 11.8vDC on the cathode end of D18. Crossing C48 I see no DC voltage (which I would expect) but only 0.24vAC key down

Jim and all. I have very limited diagnostic tools. Mainly a Fluke DVM and a QRP Labs 5watt dummy load. Referring to the dummy load manual I have been looking for approximately 20v DC at the 50 ohm loa

Everyone. I have been doing continuity test throughout the HT20 with no obvious issues. It does receive and I can listen to W1AW. The encoder is working with audio readout of frequency. It has three n

Wow! My kit is way off. Grrr… David L Cell: 512-922-0009

I have checked continuity from the top of the FETs to the BNC. And I do have some output. I did reheat the coils to ensure i did not have a bad connection One of the questions asked that I never saw a

Guys. Anybody have a HT20 open on the work bench? I am trying to ring out a problem with a new Hilltopper 20. I only have a QRP 50ohm dummy load and a VOM meter. Measuring the RMS voltage across the d

I give up. Can anyone debug my new build HT20. Will gladly pay someone to take this project on. It does not smoke. And the encoder appears to be reporting frequency but it is transmitting noise and do
