[CQ-Contest] Band-pass filters -- insertion loss

My Dunestar 600's only show a few watts loss with my Icom 775's.  No
abnormal insertion loss that I can recognize unless you try to put the wrong
frequency thru the wrong filter - then loss is near 100% (for a short period
of time before the burning smell).

Bob, AK6R
