Hi Uwe,

Thank you. I've done some /p tests today. Have to make some preparations like using a longer cable between loop and netbook, try a grounding of the loop and shielding... But i thinki will run it without shielding later. After the improvements, we can do a test, this would be fine :-)

As Michel/F5WK says, it must really have a quiet location! In a city environment it is much more critical to avoid strong mains hum, at least below 5 kHz, which is not an issue here mostly.
I will tell more tomorrow, i mean, later (2:00 AM here)

Cul,

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?
