GE MASTR II UHF mobile (Painted Handle) converted to repeater.
*5 ppm stability standard*
**2 ppm stability optional**
Items supplied with basic repeater:
Description:
This is a conversion of a mobile radio to repeater.  The lock is removed and the receiver RF connection takes the place of it.  A length of heavy duty #10 siamese wire (red/black) is supplied for the power cord.  A variety of interface options (DB-9, plain old wire tail, barrier terminal block) are available for connecting an outboard controller.  This repeater can also be build to include a NHRC internal controller.  The addition of a NHRC-?/M2 controller makes a really nice package as everything is built internally and the repeater basically becomes 'plug-n'play'.  No duplexer is supplied.  We prefer the 40 watt model for conversion as these tend to be a bit more power efficient, as the 75 watt model can only be run a little harder than 40 watts anyway.

This repeater will require a 35 amp Linear Power supply or equivalent just to run the repeater.  If an add on amp is going to be used, please allow for the additional current consumption accordingly.  Astron's are good because of their over-voltage protection.  We don't recommend switching supplies on repeaters.

The information in these sites would be used to convert the radio to 440, full duplex:
