[Elecraft] [K3] RX audio distorted on FM

[Pete-Astound]

Good evening All,

Well I've had a chance to play around some more and now 
found that at least with a local signal from the 817 the 
audio distortion on FM receive seems to have mysteriously 
disappeared.

One question I still have though is that with an antenna 
hooked up and listening on either 10 or 6 meters when the 
band is quiet (night time with the pre-amp and attenuator 
off), does the background static get at least twice as loud 
if not more when you go from any of the modes to FM?  Seems 
like it did not does this when I had just the 2.7 filter 
installed into slot 3.  Tried turning the slot 1 filter off, 
but it still defaults to it when in FM mode so I can't 
compare unless I go back in and physically take that filter out.

Thanks for your responses..
