- PRO2004.7
- Part 4/4
-
- Owner's Manual
-
- The user manual suffers from Japanese to English
- translation problems, but is fairly good, resembling
- other Radio Shack scanner manuals.
-
- A single page frequency allocations chart is included,
- but is not current. There is a very simplified block
- diagram, but no schematic. The Maintenance section
- contains a useless troubleshooting chart, accompanied
- by advice like "keep it dry" and "do not drop". Thank-
- fully, detailed service manuals for Radio Shack scan-
- ners are usually available for $5.00 or $7.50.
-
- The PRO-2004 is warranted for 1 year, which is reas-
- suring.
-
-
- What's Missing?
-
- So with all these neat features, what's missing from
- the PRO-2004? A "search and store" mode, like that on
- the ICOM R7000 and older Bearcat 250 would have been
- nice. A lighted keyboard and a signal strength meter
- would also be welcome.
-
- Having a COR (carrier operated relay) output, like ICOM
- R7000 and old Bearcat 250 have, would be useful for
- actuating a tape recorder.
-
-
- Summary
-
- If all one wants is a scanner to monitor local police
- and fire, there are certainly cheaper and simpler
- models than the PRO-2004. This scanner is for those
- who enjoy actively exploring voice communications in
- the VHF/UHF spectrum.
-
- The PRO-2004 has the right features and performance,
- especially for scanning the wide 225-400 MHz military
- aircraft band. Good design should not to be taken for
- granted. GRE engineers used the power of the micropro-
- cessor to implement useful features in the PRO-2004.
-
- Similar processing horsepower was not used so wisely in
- a recent Yaesu scanner.
-
- At about $400, the PRO-2004 provides a good alternative
- to those not wishing to spend $950 for an ICOM R7000.
