[CQ-Contest] Coax Stubs for SO2R

[Rudy Bakalov]

Does this apply to solid state amps which usually are in a push-pull configuration? I'd expect the 3rd harmonic to be an issue, not the second.

Jeff, AC0C said it perfectly -- he looks at isolation using his VNA, pays attention to what he hears on the air in SO2R mode, and works on those things one at a time.
