Saw you guys on HAM NATION (
http://twit.tv/hn) last night
That noise everyone was commenting on... Abby's cell phone (I suspect it was Abby in any case) was too close to the Mic cable.. Might have been Kendra's but I think it was Abby's.
The phone was handshaking with the tower (Possibly both of them) and the RF was getting into the mic cable.. I toss a lot of audio around on poorly sheilded cables when driving (Car has a tape player with a cassette adapter for aux in, Motor home has cd and Aux in, I sometimes play CD in car or tape in motor home or MP3 or Mini-Disc in both)
Phone will get into the audio lines if it's too close.. Even if I'm using a headset or earpiece it can get into the cord if it's too close.
Same sound.
