Its being done. By proper antenna and phasing design you can manage to
operate two radios on the same band and get as close as couple of kHz to your
own CQing frequency. Use two receivers/transceivers on two ears. WW2Y does it
on 160m, multi-multis do it. Also if you use panadapter or band scope, you
can see sudden surge in activity, you move your RX there and find a new one.
You either wait for pileup to die off or if too important multiplier, abandon
your CQing frequency and go for it. With dual receive you can also listen or
scan the band in between the holes in CQing (when things slow down).
Weird things can be acquired by practice, back in paper log days with
manual duping, I could just scan (with my eyes) the line with about 30 G
station suffixes and tell if the new is there or not. I could do real time
manual duping with abt 4 stations a minute pileup and keep track of
multipliers. It took 3 dupe sheets US/VE, Eu, rest of the world, very, very
fine print. (Now computer logging obsoleted it, have to learn new tricks.
Bummer!) Back in Drake line days, I had two receivers hitched to T4XB and
when S&P I would tune the band with two RX/hands, while waiting to get
through one pileup, I would keep tuning for another one. Foot switch would
select between each RX VFO to transmit.
Get the good antennas and radio setup and practice, practice and
practice. Scores will go up automatically :-) There is no fixed recipe,
experience and ability to adjust to flukes of propagation and band activities
separates the Big Guns from Little Pistols.
