Hi John,
Can you give me more info on your RY? TX, pwr antenna (end fed 1/2 wave?) etc?
It was amazing today. Even copied it FB on my 1M shielded loop.
OK on the Pro. I have noticed that I can hear discrete tuning steps as I tune
through the 136 spur- makes me believe this is something in the synthesizer-
which does not sound promising. There is a substantial amount of drift to it at
turn on- more than I think the synthesizer itself drifts.
