VLF,

I just built the preamp = of Renato Romero's design for a VLF loop preamp, http://www.vlf.it/easyloop/_ea= syloop.htm
The circuit is very easy and compact and looks very promi= sing, http://dl.dropbox.com/u/19882028/VLF/Easyloop.jpg. I took t= he LT1028 instead of the OP27 though.
I'm looking forward to do a new /p VLF test with my ho= ola hop loop in the forest soon.
Is there someone on air during the next= days?

73, Stefan/DK7FC
