Icom 751 Receive Drop?
 
I noticed my Icom 751 has a noticeable Receive drop from 9 MHz to aprox. 14 MHz.
S Meter and audio really drop, any help appreciated.

You might check to see if your 751 has plastic trimmer caps in the
PLL. If you do, they don't always age well. They can be replaced with
ceramic caps (I'm currently having the plastic caps replaced in my
735).
