Has anyone figured out what's going on with AM transmit with the new
release?
I get a resting power out level in the 10+ watt range, with upward carrier
shift with modulation (erratic with around 25% peak positive shift on a
Belar mod monitor). The peak output with 100% modulation is running 70+
watts, or there 'bouts, which on average might imply the carrier is moving
up to something shy of 20 watts under modulation, give or take the side of a
barn.
This isn't all that terrific, if it's working the way it appears to be --
behavior more like a controlled-carrier modulation scheme (albeit with a
relatively slow time constant). And given the output levels, it's
questionable whether this new version is going to fully drive my AL-1200.
Haven't put it on the air yet on AM, so don't know if it's going to play at
the other end like a loud DX-40 or what :-)
I almost think a bit of downward modulation might be a better answer rather
than the way it was 'fixed" in the new release.
Then again, maybe I'm just missing something ...
