I was wondering if anyone is using an XTL5000 on 900? I have one that I can't receive on 927. Everything programs just fine, transmitter works great, but no receive. I get no receive lamp and no error messages. Does anyone have an idea? I would think if the VCO is out of lock it would tell me. If I program in 935.0125 it receives fine. I have not tried a series of frequencies yet to see where it quites.

Thanks
