Moto Maratrac is a decent platform but may not make the most reliable
repeater. They are essentialy a repackaged 16 ch (99 ch) Radius mobile with
a high power amp. The VHF and UHF radios are capeable of doing the agacent
ham bands without retuning as such the recivers have a wide front end and
may not be the best choice for high RF enviroments. The transmitter heat
sink aint enough for high duty cycle especially on UHF. Install fans and
give it a shot.
We had several in service (as mobiles) and most developed thier own
different quirks, I think it is due to dirty pins or connectors on the
system board.
The local Moto shop owner had one on his (Ham) Micor repeater as a remote
base and he could change channels up and down remotely by DTMF, it sounded
real good.
For hook up you could take apart the main conector plug and solder your
wires onto the corect pins and reassemble the plug.
Here is what needs to be done for a remote base Maratrac with A7 (99)ch
head.
Function Radio
{Cntrl Cable Radio Conn.}
Black/Shield Ground 8 AWG Black (Main Power)
Tx Audio J1 Pin 14
PTT J1 Pin 12
Rx Audio J1 Pin 11
COR J1 Pin 18
If COR does not work ( I am prety sure ) you need to run a jumper from J20
pin 3 (telco/prog connector) on the radio chassis interconnect board (HLN
5343B),
to the negative side of C523 on the audio squelch board (audio PA mute).
Have fun.
