Hi OM,
Rich Measures, in his series of articles on the SB-220, mentions the
SWR problem. He suggested adding some capacitance to cure it on 10
meters.
You don't elaborate on the "huge difference". A few feet of coax
"can" make a difference in apparent SWR, if you are uncomfortable,
open the AMP, check the coax and solder joints, clean the relay
contacts and check it again.
