Seems like this is a mis-conception as well. Why do the two stations have
to be equal? Consider - to get benefit from SO2R, do you really need a
top-of-the-line transceiver? Do you really need a second amplifier? Do
you really need equivalent antennas for both stations?
If you already have a very competitive contest station -- do you really
need to double it for SO2R? I don't think so. There's several scenarios.
Consider:
A) The second radio will be used virtually exclusively for S & P. Do you
need an amplifier for this? Seems one could make virtually the same
number of QSOs barefoot S & P as one could with an amp. And if there's
some important multiplier to be had, perhaps bringing radio one to bear
might be worth the trouble.
B) Since you're not calling CQ, aren't you less likely to be digging out
really weak callers on the second radio? Perhaps you don't need such an
elaborate transceiver, or big stacks of antennas. Perhaps just adding a
single tribander and a couple of dipoles would be sufficient, or even one
of those multi-band vertical dummy loads might work. (W4AN used an R5 for
second radio practice) A second-hand radio might do passibly well, or
perhaps a miniature mobile rig. (K4OGG moves his mobile HF radio to the
shack for contests)
C) Can you leverage your existing antenna system? W4AN didn't add a
single antenna to run SO2R at his superstation. Why? He's got a single
feedline for each band. Antennas are easily switched from one radio to
the other. If you already have monoband antennas on every band, you don't
need more antennas.

I'm working to add SO2R operation to my very modest station on a tight
budget. I have no amplifier(s). I'm looking to improve my low-power
scores. I recently built a K2 (which will become a K2-100 soon), and
already have an old TS-430S. At low power, I don't appear to need any
filters. Antennas are modest -- an A3S at 49.5', 80m doublet, 40m sloper,
R7000.
I refuse to believe that my modest SO2R configuration is somehow so
competitive that SO1R operators don't stand a chance and need to be moved
to another category.
