Yesterday i prepared the soundcard so it can be "unpluged" and "pluged" by a GPIO pin. The soundcard consumes 19mA at 5VDC. Not much but why not adding this feature, so i can save energy if VLF is not running. See https://dl.dropboxusercontent.com/u/19882028/VLF/VLF%20soundcard%20switchable%20by%20GPIO.jpg Today in the morning i tested the loop in the office and later in the afternoon i installed both on the tree. https://dl.dropboxusercontent.com/u/19882028/VLF/Hule%20Hup%20VLF%20loop%2021m%20up.jpg The loop is pointing N-S, i.e. in your direction. There will be a VLF forest grabber soon. It is also a big advantage for my next local VLF transmissions because i can observe the signal in 3.5km distance which is still the near field but far away to overload the ADC... Thanks for your transmissions. So far for now from here :-) 73, Stefan Am 17.02.2016 17:54, schrieb uwe-jannsen@kabelmail.de: > OK, Paul. > Stefan, it was neither GI nor Ni. > you get some more opportunity: > carrier is on. > message: > start 2016-02-17 18:00:00 > same settings but:: > repeat on hour until the wx gets too bad. > > Uwe/dj8wx --------------010405080109090806090503 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit Uwe,

OK, Paul.
Stefan, it was neither GI nor Ni.
you get some more opportunity:
carrier is on.
message:
start 2016-02-17 18:00:00
same settings but::
repeat on hour until the wx gets too bad.
