[Motorola] GM300 model ID

[Eric Lemmon]

Jeff,

Not necessarily.  According to the mod sheets at the front of the GM300
service manual, M33GMC20D1A_N does imply 136-162 MHz, but I there are
several numbers for the 146-174 MHz split.  The complete GM300 Service
Manual is available for download in parts on the Repeater-Builder site.  Go
here for the first part:
www.repeater-builder.com/motorola/gm300/gm300-service-manual-part-a.pdf

Parts A and B contain the model charts.  You are correct; the GM300 was not
made in a 136-174 MHz range.  The 136-162 MHz split was created for the old
136-144 MHz military band.

73, Eric Lemmon WB6FLY

Does anyone know if the model ID chart BatLabs has for the GM300 is correct?
I see many GM300 radios on Ebay claiming to be 136-174Mhz.  According to
BatLabs that bandsplit does not exist.  I'm looking for the 136-162Mhz split
radio.  So that model number should be something like M33GMC20D1A .  Is the
last number in the model number the one for the bandsplit?  Is the (1) truly
136-162 and the (2) 146-174Mhz for the GM300?  Thanks,Jeff
