Hi Joe,

No recent snow here, thankfully, but cold. I went out twice last
night to change taps on the LF matching transformer as the
temperature plummeted. Awoke to find a frozen drain pipe this
morning. But on a positive note, static levels on LF are down!

I beg to differ. For the average amateur radio operator like myself,
EbNaut is absolutely incomprehensible. The first thing people want
to know is what equipment is required for LF EbNaut and how much is
this going to cost? But answers are hard to come by. I could never
get an answer as to whether my HP 3325B with high stability option
was good enough. When I asked about amplifiers for EbNaut I was told
linear is a must, but now I find people are doing it with nonlinear
amplifiers. How are we to learn? I really wish someone would write
LF EbNaut for Dummies. If I could somehow come to grips with it, *I*
would be more than happy to write practical articles for those
coming behind who will also be struggling.

73,
Paul
