Custom Built 10 meter or 6 meter
General Electric MASTR II Repeaters
by Repeater Builder


10 meter & 6 meter models
GE MASTR II low-band mobile converted to 10 Meter or 6 Meter repeater.
Items supplied with basic repeater:
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-X/M2 controller makes a really nice package as everything is built internally and the repeater basically becomes 'plug-n'play'.  No duplexer is supplied.

The repeater will require a 35 amp Linear Power supply or equivalent just to run the repeater.  If an add on RF Power 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 full duplex:
