[Elecraft] K2 80m Scratch RX audio

[Tom Campie]

Hey guys, I'm having a problem with my K2 and scratchy RX on receive audio.  The problem exists with or without headphones and at any volume.  I tried turning off AGC and it still was there and its on all strengths of signals (I have limited access to anything stronger than S3 or so due to antenna situation)  I am using a 66' doublet in the attic fed with 300 ohm twinlead through the Elecraft 4:1 balun into the KAT2.  I haven't noticed the noise on other bands, just 80m.  Any ideas as to what may be causing this noise?  I'll try to get a recording of it soon.  Stay posted.
