are you using an ex Ham transmitter?
I hear with LSB/USB get further than AM but is the LSB really wide enough
for quality audio? Got a grandpappys MP1000 here that will rag 50 watts AM
all day long, but the band width is to narrow for anything like nice music
audio... Speech is nice though. Maybe there is a wider AM filter than stock,
some Ham wizardry to make it fit a decent audio element on to the carrier,
