I want to build a repeater from 2 gm300s. All I have is the 2 radios and the powersupply. I need some guidance to exactly what else is required, and some info on where to get the interface unit. Do I HAVE to have a duplexer? or can i just use 2 antennas? Thanks for helping a real amateur.

With respects to your desire to make a system
from 2 GM300's, yes you have about 1/2 the materials required.
One of the 1st things I would recomend is a
FAN for the transmitter unless you have a unlimited supply of GM300's as when in transmitt for a long period of time, you will find the Heat Sink getting very hot.
Next, would come the R*I*C*K and those can be found for anywhere between 200.00-300.00 and has all the Cables necessary to conncect the radios together.
The RICK also has the Delay Drop out timers,
Time Out Saftey Delay Timers, Audio controls
( to make the audio sound proper )
One can use a simple " Connect" cable, but be
for-warned, that method has NO SAFTEY features at all.
It is recommended ( if you are using UHF ) to use a Duplexer to save monies on a Extra
Antenna and transmission line.
If you use RG-142 B/U Cable for your Duplexer
to Radio Interface along with good construction outlines, you should have a good
system
Trying to " Shortcut" any of the above can
be costly to your project.
If you email me, I think I have the part number for the book which shows a varity
of configurations, and how the RSS has to be addressed to make it work properly
