From: "Mike Schettler" <mschettler@...> To: <n0rc@...> Subject: a comment about 'the Rock-Mite files' Date: Tuesday, October 15, 2002 10:46 PM Hi Rod, Here's my contribution-- a Rock-Mite 20 with AAPB. I initially had the howl others have reported, but packaging in a plastic box seems to have fixed it. I would be interested in hearing others experiences with this problem. My guess is that something I changed in the grounding is the cause. I noticed that the additional X2 gain from the AAPB has resulted in a sidetone that is too loud for my taste. Hopefully a simple RC fix will cure that, and maybe shape the audio as well. I'll pass along any insights. I decided to not use the single pole audio filtering in the AAPB. Using a simple SPDT switch selects either both poles, or none. The addition of the AAPB volume control is most welcome. I'll be bringing my RM20-AAPB with me to Pacificon. Hope to see you there! 73 Mike Schettler WA6MER
