Well, after getting some excellent advice. I have decided to add a 500 Hz filter (model 217) to the 9 MHz IF of my Omni V. Anybody have one for sale? Contact me via email at jcharley@bellsouth.net. Tnx. Crit/K4BXN --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---
