IC-706 MK2 Poor RX FM
 

My IC-706 MKII after warm up few minutes ,the FM RX lost sensitivity
in all
bands, only strong signals, are receive. The other modes still with
normal RX.
If change to SSB or AM is OK. The problem is only in NARROW
FM, Normal FM and WIDE FM, the TX is OK all time.

I´ve sent an e-mail to Icom tech support but they said only sorry and
no ideas for this troubleshooting.

I would appreciate very much any suggestion, comments or help.

Thanks,
