Hi Gang I'm looking for the following filters for my TS450S rig, a 2.1 Inrad (not sure of Inrad's part number) or a 2.4 Kenwood SSB filter (yk-88s-1). I already have a Kenwood 1.8 installed in the rig...Any one have one of these they'd like to get rid for a fair price? Thanks in advance, 73 Mac David S. McCallum/w7sac/4,USAF Ret./Chief Mac
