prog of desktrac using one maxtrac for tx gm300 for tx

[petem001]

Hi!

I have a desktrac UHF repeater that have a bad PA board on the TX side. both radio are maxtrac.

I want to switch the faulty maxtrac for a GM300 that I have,its a 8 channel UHF, its working great on the repeater frequency.

Now, I know that I cant just switch the GM300 and plug it to the connector of the desktrac as the front connector have 2 more pins then on the maxtrac, but If I am not too crazy the control is done by the 16 pin connector in the back of the radio.

What I need to know is how should I program both receiver and transmitter to make it work (accesories and stuff)

Thanks
