Hi Guy, It's that way i was thinking to use the P3! -1- ALWAYS on the sub-receiver output. -2- ALWAYS on a separated antenna.
My idea was to externally switch the 6m (or internally if possible?) antenna from K3 sub-rcvr to main RF when some activity was "detected" on th P3. When "working" on 6m, no necessity, (always speaking for me..) to "monitor" a 10 to 20m band! In my case, as i'm very space limited, no room for a 2nd 10 to 20m separated antenna for diversity... But a separated 6m antenna is feasible. (for the moment, i use only a vertical for 6m, no DX, but not too bads QSO) 73, Rudolf, HB9ARI Guy Olinger K2AV wrote: > The trick involved in that switch is a very high isolation between the > two IF's (RXA and RXB) currently very nicely highly isolated.
