Hello Jim, LFers,
Thanks for clarifying the issues about my loop...I really am greatful to all
who have offered and the gang here are a great bunch
of fellows with plenty of experience to tap into.
Regarding the tuning of the loop, it is quite sharp, so at least I don't have
to worry about that aspect.  I'll be trying out the transformer approach in
a day or two...I've got it wound, but the weather is a bit wet for outdoors
activity at the moment.  I used a core from a SMPS, with taps on both
primary and seconday so I can try out different ratios.
I think I'll put together a preamp too, as even if the rig isn't too bad at LF,
it wouldn't hurt to have a little boost.  Your design which is shown in the
new book "LF Today" looks interesting, as I want to be able to use the
loop for NDB DXing, Lowfer monitoring, and of course on 136 kHz.
Thanks again & 73, J.B.
