[CQ-Contest] SO2R - How Good is Good Enough?

[Pete Smith]

I've just spent a lot of effort, and probably too much money, on antenna switching and filtering for SO2R.  The resulting system seems to work quite well, at least at 100 watt power levels, but I realized I don't have a good sense of what experienced SO2R ops and station builders consider to be "good enough."  In particular, how close to the harmonics of your transmitter frequency should you be able to listen effectively with the second radio?
