Interesting ... I will check it out. I had a '1000D back in the early
90s that I used on 160. I had some beverage antennas for receiving and
it was the most amazing thing to listen to weak stations in diversity
mode with the beverages on the sub-rx and the full sized vert on the
main. I think our brains can do some incredible "cranial noise
reduction" when the signal is heard from one receiver in one ear, and
the other receiver in the other ear. It give the sound a third dimension
that lets you listen "around" the noise.
There were many times that solid copy could only be achieved in this
way, and either receiver alone only produced an unreadable signal buried
in noise.
I found it quite incredible. Having a dual diversity system with two
good receivers and phase-locked tuning is, to me, the Holy Grail of Low
Band receiving set ups.
