What's the transformer turns ratio? Any idea what the inductance of the loading coil is ... or how 
much L was required on 137 or 500 kHz if using the same antenna? Antenna current? Inquiring minds 
want to know.

Just fired up SpecLab http://www.w1vd.com/grabber.html hoping to catch a glimpse. Any chance for 
QRSS60 instead of 30?

Jay
