I can hook my McKay Dymek DA-5 ferrite bar antenna to my GE Super one (or two) and haul in a station every 10 khz on the mw band just about any evening.
Keep thinking that I'll try it (the DA-5) on my 2000X (now that I think about it, don't think I've ever had it on am) but never got around to it. I have tried it on several boat anchors but it seems right at home on the GE's
