Thanks Peter for your comments.I can see that there is a graet deal in what you say about high output (large size) high "Q" LItz wound loops. The high Q does the filtering ! and no Amp is needed so NO IPs. as Rik says. However I will persevere with my big untuned loops, but mebbe I need to build one of yours for comparison . 73s Laurie.
