Re: "I never got it to work", the story of a £15 PRC320
It was kinda methodical - the sort of follow-the-trail-even-if-it-does-not-seem-to-lead-anywhere stuff I tought my techs..
"Why did they do this?" was always a fun game.
The PRC320 in question continues to work well, though I still don't understand its "AM" behaviour.
Officially it's supposed to run a sort-of 'controlled carrier' AM, where the basic carrier-level is varied with a tine-constant of several seconds to follow the audio.
Talk, and the carrier-level rises quickly; stop-talking and the carrier drops-back to save battery-power [plenty of 1950s/1960s ham-radio gear used the same approach]
What seems odd on this particular PRC320 is that yes, talking on 'High Power' AM the carrier slides to follow the audio - but then when I stop talking it ramps-up the carrier to something like 50 Watts, before after a few seconds throttling it back to a more-sensible 'idling 10 Watts DC input'.
I'm not complaining though: working on 80/160M AM I'm regularly complemented on my audio-quality.
