If its a high power GM300, you cannot turn it down low enough to have it be
clean and run cool enough to key down for that long of a time. Seek out a low
power (1-25 watt model) turn that down and use a high speed fan to cool it.
(those radios at full power are 20% duty cycle, so power would ideally have to
be cut to 20% output, motorola only rates them to 50% output for the high power
units)

P.S. - I use GM300's and CDM series stuff as link radios

A club I am a member of has lost their UHF remote base radio. I have a GM-300 5-pin radio I can pull to loan them indefinitely. Their requirements are a binary select, frequency agile UHF transceiver.

Subject: [Repeater-Builder] GM-300 5-pin UHF radio as remote base
If this radio will work, what mods do I need to do to it? The remote base is used for IRLP, Southeastern Linked Repeater Net, and Skywarn. With the SLRN it could be keyed down for as long as 1 - 1 1/2 hours.
