[ICOM] Icom 7000 and contest conditions

John: Go take a look at Bob Sherwoods site,  www.sherweng.com and view his presentation on roofing filters. It may provide you with more insight, especially when in the CW mode.

Last Thursday I turned the Icom 7000 on using 40 CW, put the bandscope in slow
sweep mode, and noticed some big signals 30 KCs up or so, so I tuned up there to
see what was going on.  It was the NCCC sprint which I had forgotten about.  I
had the 7000 set up for normal 40CW operations-preamp off, 500hz filter, sharp
filter, fast AGC.  One thing I quickly noticed was that the receiver seemed to
be getting hammered in this sprint.  The AGC was pumping badly, and it just
didn't seem to be up to the task. Signals were difficult to copy, as they
were being affected by other signals outside of the passband. I hadn't
noticed this problem with other small HF/VHF/UHF rigs like the Yaesu FT857D and
Yaesu FT100D, which I have run in contest conditions also.

What was going on?  Did I have the rig set up incorrectly, or is the receiver
in the Icom 7000 just not up to the task for this type of operating?
