[1000mp] Icom vs Yaesu QSK???

Wed, 10 Mar 2004 16:18:41 -0700

This one catches me by surprise.  I talk to a group of CW ops every
morning on 80 meters.  Their signal strengths vary from noise level to
S9+40.  I can't say I've ever experienced any kind of "recovery" issue
as you have apparently noticed.  I almost always just leave my AGC
setting on "Auto," and admittedly don't know whether that is slow or
fast or something else for the CW mode.  I did put in the Inrad front
end mod, which I believe included some kind of AGC mod as a "bonus."  

Is the phenomenon you described one that you would expect to observe in
roundtable QSOs with a mix of weak and strong signals at 35+ wpm?  Or
would it only show up in contest conditions for some reason?

I did a fair share of cw contesting with the MP, almost 100% qsk.  My
issue 
with its qsk performance was certainly NOT objectional noises in the 
headphones or truncated characters.  It was the (at times) horrendously
slow 
turn-around (i.e., recovery from transmit to receive) of the rig in fast
AGC 
mode.  Fairly often, it would fall into a funk of taking several hundred

msec for the s-meter to fall down and receiver gain to come back up
(even 
with rf gain throttled back to 12 o'clock) and I would often lose the
first 
few elements of calling stations.  The turn-around was actually markedly

faster with slow AGC.  I owned two late MP's ('98 and '99) and they both

developed this problem.  I've heard reports of newer MarkV's also
behaving 
this way.
