After owning my Jupiter for several months, I got around to trying it
on AM yesterday. The reports were that my audio was very distorted...
perhaps due to over-modulation.
In the prior firmware release (1.12) when I tried the AM-AUTO-SET
procedure described in the addendum in my manual, the power out
indication would increase and decrease but would never return to
receive mode until I pressed the "Tune" button again.
With the new 1.16 release, pressing the "Tune" button does not
trigger the same behavior at all. I do get a steady indication of 16
to 20 watts out. I think this is now the desired behavior of the tune
function, which limits the output during the tuning process. But...
it would no longer seem to relate to any automated power level
setting while in AM mode. Of course, as I said previously, I could
never get that power level "hunting" behavior to cease in the earlier
firmware releases anyway.
I would like to know, if anyone is successfully working the AM mode
with their Jupiter and if so, where do you have the "AM Drive"
adjusted to. It appears that setting my AM Drive to about 35% gets me
an unmodulated carrier of about 25 watts. Does that sound right??. I
have the Mic Gain at about 50% which is where I would normally have
it for SSB operation.
Today, with the Santa Ana winds and the accompanying high noise
levels, I have been unable to hook up with anyone, but I would like
to know if I am on the right track .. and if my Jupiter is reacting
the same way as everyone elses.
