I just finished build 4 more LZ1AQ loop amplifier boards. They work great with a 3' to 4' diameter loops. I will not ship out of the US. If interested in info and price please contact me off list at everettsharp (at) aol com.
I also have a very nice active whip antenna board that works very well from 100kHz to 108MHz. I am currently using one on my ELAD FDM-S3 with a splitter to give me coverage from 100kHz to 108MHz. I have it hanging out of a tree with a 6' wire for the antenna.
