I have both a vhf and uhf Micor repeater that I'm interfacing.

I now know a whole lot more about Micor repeaters than I really wanted 
to. The short version of the problem is as follows:

The COS signal from the audio/squelch board goes away when the TX is 
enabled. If you transmit a continuous carrier on the input, The COS 
comes up for a split second, keys the TX then goes away. After the 
hangtime expires and the TX drops, the whole things starts again.

I have the exciter and RX into 50 ohm loads. If i put the A/S board 
and squelch gate into the uhf unit, it works fine. I have checked and 
double checked everything. It just doesnt make any sense. Any ideas 
would be greatly appreciated.
