[ICOM] Garbled receive on lower bands

[Larry Young]

The original plastic caps used in the PLL circuits degrade with age, and can cause the condition you describe. Look at the links here for additional information on the caps. http://www.angelfire.com/biz2/mts/

I have an IC-751 and IC-751A and they both exhibit this malady.  SSB on 40
and 80 sounds garbled, CW sounds almost "hissy".  20 meters and up seem ok.

I have used the "A" for years without incident.  Then the problem occurred
only at turn-on and for awhile thereafter in the beginning, and now is
constantly there.  The non "A" is a rig I acquired with the issue in place.

Any help would be appreciated.

Thanks, & 73,
