MTX 9000 Receive issues

I am trying to move two mtx 9000's into the ham bands. I have no trouble with tx on any frequency within the entire ham band. I seem to be having trouble with the receiver locking anywhere below 926.400mhz. Is there any way to tweak the vco to get this radio to receive at 921.000mhz? Ihave looked on this board but all I have seen is discussion on t/a issues, is this the same thing?

Thanks

I understand what your question and problem is, but I thought that the
"new" standard for 900 mHz was 902+ transmit and 927+ receive. Are you
working a system that still uses the "old" 900 mHz setup of 921 mHz?
There is an interference problem involving AVM systems between 918
and 926 mHz, hence the most recent changes in the bandplan. I see
that Mt. Beacon is still on 921 MhZ.

You are correct Mt. Beacon is still 921.200mhz, and I beleive Albany Is 100khz down from that. I was not aware of the interference problem, is there anything that you can point me to about this interference?
