I have noticed that my TH-F7 has gone a bit deaf on UHF. Its not 
completely deaf - maybe 15dB down. I connected an external pre-amp and 
the signals came up OK. The rig is deaf on both the A and B band. The 
VHF side of the radio is OK.

Maybe the UHF front end MOSFET has blown? Is this a common problem? 

Thanks
