"So I transfer the headphones to the speaker output, so I can
reduce the AF gain setting in an attempt to get away from the
raucous AF limiter. This works for a while, until finally one
loud signal blows out the K3's audio amplifier. This is the
second time that has happened to me. I guess I'm a slow learner
on that issue.
Something really needs to be done here. My suggestions would to
raise the agc threshold further, and increase the slope of the
agc line (that would mean a slp setting of less than zero). The
AF limiter threshold also needs to be raised, and the AF speaker
output needs better protection."
With all the discussion of AGC on/off, threshold levels and gain throttling,
etc. for improved performance in pileups, I haven't seen any further
mention
of what I consider to be the most serious problem reported by K6LL, namely
that the K3's audio amplifiers can apparently be damaged by user control
settings.
If this is considered acceptable (I don't believe it should be), are
these control
settings adequately described in the K3 user's manuals and updates? Is the
susceptibilty to damage confined to K3's where the hardware audio
modifications
have yet to be made?
