[Motorola] Quarterly Request:Want to buy - UHF Business dispatcher

Sat, 01 Nov 2003 17:04:49 -0800

Did Moto produce more than one Dispatcher line of radios?

I have a UHF "Solid State Dispatcher Radio" (from the info plate) 
with a model number of D14DCN-3100A Type CC4099 on 462.5 simplex and 
a PL code of 4A,

Is this the same radio of which you speak, or another line?

How "movable" are these to the ham band?

           Thanks...Dennis
