My wife bought me one for my birthday last month. So far I am very
pleased with it. One of my favorite features is "program scan auto
memory write". This feature alows scaning between two scan limits with
all hits saved to memory channels 800-899 (no dups). There are ten scan
edge pairs for setting up continuous scanning between any two freqs.
Another great feature is the ability to store a "select code" with any
memory channel. Select codes are "S" (skip) and 0-9. This allows you
to scann for only select code 3, for example, so that you can categorize
all memories and scan for them easily. This is important since there
are 900 regular memories plus the ten scan edge pairs.
I have no way of judging the sensitivity, selectivity or IMD or the
receiver but I can say it is more sensitive, selective and noise free
than any of my ham band only VHF/UHF equipment. In fact it is my
prefered receiver for 2m and 70cm.
Scan rates, delay times and may other features are programmable from the
front pannel.
It can be programmed to to both a primary scan (simple, normal scan) as
well as a lower priority background scan. For example, say you want to
scan the VHF areo freqs from say 127-139 MHz to find out what was there
and save any hits to memory while scanning the local trunked police
freqs at 840 MHz. Simple. Program in the police freqs in say memories
100 thru 150. Program in the scan edges of the areo band into one of
the scan edge pairs. Then select programed scan with advanced scan
mode. Presto. While scanning the police freqs it will do double duty
and check for any activity on the areo bands. There are five simple
scan modes and three advanced modes. Duty cycle of the
forground/background scans is, of course, programmable.
The computer interface is the same as previous Icom gear so you can
control up to four receivers from a single computer port.
So far the only thing that I have a problem with is a relay cutting in
when it switches above 800MHz (don't know the exact freq).
Finally since it is an all mode, continuous coverage receiver, there is
absolutly nothing between 25 and 2000 MHz that you cannot receive.
They are extreeeeemly hard to get hold of. My wife bought mine through
Grove. The Icom folks at HAM-COM '92 (Dallas) this weekend said that a
certain US government agency had purchased several thousand of them
because they were so much better than most of the milspec stuff...
