[Elecraft] Nasty spurs on RX with new KPA500

[Gary NC3Z]

Yes Jim, everything is bonded. All 120V and 240V AC goes through ICE 
suppressors on a SPG, all shack equipment is bonded to that, etc. It's 
not a bonding issue (I have read and followed your "cook book" long 
ago). Several direct e-mails indicate it's an issue with the front panel 
board and this is not the first of this exact issue. So right now am 
just waiting for Elecraft to open back on Monday.
