I've never run anything stronger than a SB-220 or a 30S-1, and I was wondering after seeing some of the European QRO+++ stations ....... what do they use for a rotor loop ? Seems that RG-8 and PL-259s or type "N"s would be a limiting factor to any QRO project ... not to mention burning up TA-33 CL traps ( or other trapped beams ) ?? Don WA4NPL
