Me too on wishing you could add a roofing filter on the sub rx. I also has
a preamp that stays on. I've had folks over in contests that have
commented on how incredibly clean the main rx is versus the sub rx which
sounds more like a front end they are used to hearing on their rigs in
contest conditions. This comparison has sold more than one Orion! So
maybe it is a good marketing tool <grin>.
I tend to put Beverages on the sub rx and my transmit antenna on the main
when doing the diversity thing - the lower signal level lessens the effect
of limitations on the sub rx.
