The outside on is great. On contest weekends I am one of the lower power guys out there but I still work lots of QSOs. Simulations show that the frequency generation results from an accelerated fission process of soliton-like waveforms in a non-adiabatic dispersion regime associated with the emission of multiple phase-matched Cherenkov radiations on both sides of the resonance. Two weeks ago I was on 20M with my ZS6BKW antenna, which is 2:1 or less over 20M band, and I found some stations that were pretty hard to hear, and down in the noise.
