I have 3 of them, One has HT-90 crystal controlled units inside. The other 2 are GP-300 and can be programmed. It is a bit of a hassle, as I do not have whatever is the proper interface, so I took the units out and popped them into gp300 cases and programmed them, then put them back into the Systel. Works! If yours has very rectangled shaped units that are just boxes, then it is most likely HT-90 and crystal controlled. Maybe you can find crystals, not sure. But if the 2 units look like a HT out of the case with speaker hole, kind of rounded corners, then it is probably the GP300 unit and much better. Mine work great with GMRS.

I recently was given a SYSTEL unit made by Motorola, on 464.../469... with duplexer and looks to be a repeater, with low level output (2w or so). Would be great for remote work on GMRS, does anyone on the group have data/information on this little cutie? Also I am looking for a schematic for an amplifier used with the portable. a UHF with the number N1275a? thanks in advance -- Rick
