So, does anybody here have any idea why the coax coil choke and the

Was the coax choke single layer or bunched?
How many turns on what diameter?

Just 4 turns about 6" diameter, bunched up and secured with cable ties
as GAP recommended. Hard to believe there was some kind of narrow-band
resonance that just hit 20M, but I guess stranger things have happened.
