[1000mp] No Receiver 7.5 - 14.5 mhz

[Tom Homewood]

I have a problem that just started on my MP. I have no received signal from
7.5 to 14.5 mhz on the main receiver. I can receive signals on the second
receiver. I get zero power output if I try to transmit on 20 or 30 meters.
If I try split operation I also get no transmitted signal.

As I tune from just below 7.5 the rx goes from working to not working and as
I tune from just below 14.5 to above the receiver comes to life. I can
always hear some background noise but no signal in the 7.5 - 14.5 range.

Any one have a suggestion where to look first? I didn't see anything quite
like this in the archives that I reveiwed.
