Dear Paul, thanks for replying and helping.
I will definitely first get a dummy load. Possibly, I have a SDR that can do HF? monitoring. No other radio as such to monitor.
Can you please tell why should I lower this to 12V? it works well @ 15V (hopefully not frying the finals).
The only goofup I did was while assembling the kit, I connected LS to the wrong port and hereby frying a diode that refers to battery operation ? if I am not wrong?
I have ordered 10x IRF510s and will try my best to not fry them with ESD :D
The antenna SWR was measured using my RigExpert analyzer.
I do not have inline power meter so measuring DC current in series is only? my option.
The current pull is same on all bands
