[ICOM] Raspy CW note on IC751A

[Gary Nichols]

Good afternoon all, I recently purchased a used IC751A on Ebay and added the
narrow CW 455khz 250 hz filter to this radio.  I find the CW note on RX is
very raspy sounding while the same station on my 746pro is quite pure
sounding.  Any suggestions before I start pouring through manuals and
reported fixes on the internet?  I am seeing this on the 40 meter band but
due to few signals anywhere else don't know if all bands are affected or
not.  Could this be symptoms of defective trimmer capacitors I have read
about elsewhere?

Thanks in advance.de gary, kd9sv
