Many thanks to everone who responded to my comments on pre-amps and loops.I
am still not certain what to do-but at least have some more ideas. I hope
that the >resulting discussion was of general intrest. 73s Laurie.
Hi Laurie,
I have made a number of LF loops and have not had much luck with pre-amps;
they all seemed a bit noisy or I found there were lots of signals around
that shouldn't be there. I found the best loop is the 2m square one that is
described on my web site, wound with Litz wire and without an amplifier.
I confirm that the loop characteristics are very much modified by the nearby
resonant LF transmitting antenna and the fix is to detune the Tx antenna on
receive.
It is also a good idea to detune the receive loop on transmit!
Regards,
