R7000.2
EXAMINING THE ICOM IC-R7000 RECEIVER
Bob Parnass, AJ9S
The long awaited ICOM R7000 is here. I bought my R7000
(S/N 001400) on June 14, 1986 from Spectronics, and
agree with other R7000 owners: ICOM did their homework
on this radio.
I had several questions about the R7000 that were not
answered in ICOM's advertisements, and could only be
answered by fiddling with the real thing:
1. Can one set the R7000 to behave like a "normal"
scanner, waiting for a transmission to complete
before resuming the scan? Contrary to the review
in July Monitoring Times, the answer is YES.
There are 4 choices of when to resume scanning
(or seaching), and this is one of them.
2. Does the R7000 have a "search and store" mode,
like the old Bearcat 250? Yes, and it's well
done. There is a mode which will search between
two frequency limits, and store the active fre-
quencies in the top 20 channels. The R7000 is
smart enough not to store duplicate frequencies.
3. Does the R7000 use the concept of a "channel
bank"? Yes, one can select and deselect any of
the 99 channels to be in a bank. This is much
more flexible than traditional scanners. For
example, the user can form a bank composed of
channels 2, 5, 31, 48, and 79.
4. Does the Priority Scan feature work like a Bear-
cat scanner? Well, sort of. The best way to
describe the ICOM R7000 priority algorithm is to
say is resembles using a Bearcat scanner in the
manual mode with the priority feature selected.
One cannot "scan" more than one channel on the
7000 while sampling the priority channel. On the
plus side, the priority frequency does not use up
any of the 99 channels, but is programmed from
the keyboard and has its own register. The user
can use the "scan speed" control to set how often
the priority frequency is sampled, a nice touch.
In practice, the R7000 dwells on the priority
frequency for a little too long, essentially
chopping up the signal on the non priority fre-
quency too much.
