Bob,

Here is some information on the PRO-2004. It's not a trunking scanner,
but most scanners don't cover the military aircraft band and cellular
phones. As far as it working "in the hills", it all depends on what antenna
you use.

PRO-2004: 1986 vintage. Top of the line, wide band scanner. After a diode
is cut, enjoy continuous coverage from 25-520 and 760-1300 MHz, AM, NBFM,
and WBFM. Has 300 channels in 10 banks of 30, backed up by conventional 9
volt alkaline battery. Any channel can be designated the priority channel.
Scans and searches fast. Lots of well designed features, like 10 pairs of
search limits, Lockout Review, default search increment and emission mode.
Sound Squelch allows skipping dead carriers during search or scan. Metal
cabinet, good internal construction and shielding, but no mobile mounting
bracket or DC power cord. Soft touch membrane keyboard. Good sensitivity
and selectivity. Very good radio. See "Product Review: The Radio Shack
PRO-2004 Programmable Scanner," by Bob Parnass AJ9S, in The Radio
Enthusiast, February 1987, and Monitoring Times, March 1987.
