Subject: [RailScan] Motorola GP68 Programming Help Requested


I purchased a Motorola Portable GP 68 to use for mobile rail 
scanning as a result of a few favorable prior comments from this 
list and other places. I also use scanners, but wanted this unit for 
added flexibility.  This unit has a keyboard and is billed as "user 
and field programmable"

From my research, most of these keyboard units are indeed field 
programmable, but require the removal of "jumper R417" from the 
circuit board, a procedure not obvious or documented.  There also 
may be a series of key strokes not readily published that can 
accomplish the programming. Out of the box, this unit can search and 
lock on to a single frequency, but the scanning feature, frequency 
entry into a channel, and other similar features are not obvious.  I 
need field changeable programming for flexibility as opposed to 
dealer fixed programming.

I have the document available from www.pe.net/~atd/gp68main.htm 
which details the programming steps, but it's useless without 
unlocking the unit to accept those strokes.

I would appreciate any help or source.  Thanks in advance.
