Betreff: LF: VLF, easyloop

VLF,

I just built the preamp of Renato Romero's design for a VLF loop preamp,
http://www.vlf.it/easyloop/_easyloop.htm
The circuit is very easy and compact and looks very promising,
http://dl.dropbox.com/u/19882028/VLF/Easyloop.jpg. I took the LT1028
instead of the OP27 though.
I'm looking forward to do a new /p VLF test with my hoola hop loop in
the forest soon.
Is there someone on air during the next days?
