Here in E-field I get carrier S/N: 20.79 dB in 34.7 uHz.
I'm impressed with your E-field reception Eddie, it's
always a dB or two better than mine.

I couldn't decode that one at all from E-field only.  I have
to use E and H combined.

I'd better get get some of those 3dB gain cable ties.  I think
they're available from audiophile shops.
