I am fairly new to chasing satellites. I have the FM sats down fairly well and I am trying to get into the linear birds. Here’s my set up: -Arrow antenna with diplexer mounted on bike repair stand.-ICOM 2730a (I used this with great success on the FM sats)-2 Yaesu FT-818 (replacing the 2730 for all sats) I’ve read many articles and visited many web pages but I am confused a bit with desense. When operating v/u where should the filter go? On the 2m side or the 70cm side?Does it matter if I am operating FM or linear as far as desense is concerned? I have no problem hearing myself while operating FM v/u sats using the FT-818s.Can I use the diplexer in the Arrow antenna as a filter? Still trying to get the hang of the linear birds. Thanks for the help.
