[CQ-Contest] SO2R on a tiny lot

While I don't have a small lot, all my antennas are on one tower
(402CD @ 86 ft, TH7s @ 76, 40 & 25 ft, 80m slopers and 160 inv vee).
The upper 2 TH7s are phased and the bottom one is used for radio 2.
I use both stubs and bandpass filters on both radios. Barefoot, each
station doesn't know the other one is on the air, unless within a few
KHz of a second harmonic (eg., 7010 and 14020). When running full
power, again, it is pretty clean, with just a little trouble with
second harmonics, though the QRM extends maybe 10-15 KHz on either
side. No bad, considering the 40 and 20 antennas are only 10 ft
