Hello Jim, LFers,

Thanks for clarifying the issues about my loop...I really am greatful to all

who have offered suggestions...you 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.
