Custom Built 10M & 6M
Motorola MICOR Repeaters
by Repeater Builder

MICOR Low-Band mobile converted to 10 Meter or 6 Meter repeater.

Items supplied with basic repeater:

Complete radio (We supply) 45, 60, 75 or 110 watt models available.
45 watt units will run continuous duty at 40 watts with fans on PA heat sink.
60, 75 and 110 watt models will run about 50 - 60 watts in continuous duty with fans on PA heat sink.
Receiver and phase modulated Exciter converted and tuned. (see below)
Crystaled on your frequency. (recrystaling of channel element)
Duplex modifications done.
Separate receiver antenna port. (professionally installed on front panel casting)
Heavy DC Power Cord supplied ( ~ 4 foot length)

Items not supplied with basic repeater but are available as options:

True FM Modulator exciter available for additional charge. (Great for flat audio throughput.)
PL, aka CTCSS available extra. (Can be configured for encode, decode or both.)
Preamp. (Many models available extra.)
Controller. (Many models available extra.)

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.

We guarantee our MICOR receiver conversions to have stated factory sensitivity specification; which is .35 uV (-116 dBm) for 12 dB SINAD. Commonly, our receivers do about .30 uV (-117.5 dBm) and with a MICOR preamp about .15 uV (-124 dBm) for 12 dB SINAD and a squelch threshold that breaks at less than -130 dBm, something below the calibrated range of our service monitors.

We modify the low-band exciters RF circuitry for use in the 10 meter or 6 meter band as described on this website, and we also eliminate the mic bias.

The low-band PA's will tune the ham band and have reasonable efficiency.

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.
