Custom Built 440, GMRS, or UHF
Motorola MICOR Repeaters
by Repeater Builder
 



MICOR UHF mobile converted to UHF Commercial, GMRS or 440 ham repeater.
Items supplied with basic repeater:
Description:
This is a conversion of a mobile radio to a repeater.  A separate receiver RF connection is added to the front panel.
A length of heavy duty power cable (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 built to include an NHRC controller.  The addition of a NHRC controller makes a really nice package and the repeater basically becomes 'plug-n'play'.  No duplexer is supplied.

The MICOR UHF receiver requires modification of the oscillator multiplier for use below 445 MHz in the ham band.  This modification is done if the unit will be receiving on or below 445.000 MHz.

The information in this site would be used to convert the radio to full duplex:
MICOR repeater conversion.

The repeater will require a 35 amp Linear Astron 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.
