My default KAT500 configuration for 6 meters is Mode - Manual, Antenna -1, Others - Bypassed. If I select Mode - Bypass I hear a relay click but Antenna and Others are unchanged. There is no change in SWR. What changes between Mode - Manual, Others - Bypassed and Mode - Bypass, Others - Bypassed? Which relay(s) is/are changing? 73, Andy k3wyc
