Do you use slow or fast AGC on the AOR7030?

Dear Tom,

I'm almost ashamed to write this reply: for listening, I generally do
not use either "fast" OR "slow" AGC on my AR7030m Plus.

I use "medium!"

I can just hear everybody now -- "GROAN!!"

Best,

Joe

Joe, I wonder if the pitch shifting you hear on the Sat 800 or R8B might be
mitigated by using Fast AGC. That would maintain a more constant level to
the synch AM detector. Maybe you might hear pitch shifting on the 7030 if
you used Slow AGC.

While I agree with you that Fast AGC is advisable while tuning, I don't
think it is right to say that Slow AGC is always optimal for listening. I
think the choice depends on fading and interference. Rapid deep fading and
carrier-less SSB interference are best handled with Fast AGC. Slow AGC
provides lowest distortion on AM and SSB and eliminates fatiguing syllabic
pumping of background noise and interference on SSB speech. As always,
there's a tradeoff, and Medium is a compromise - as you apparently have
defaulted to on the 7030.

Of course, I have no idea what your Medium is. I tend to think of these
speeds to be on the order of:
Milliseconds Speed
tens Fast
hundreds Medium
thousands Slow

Boy, this Subject needs to be changed...E5 Gloat?
