Re: VLF: OE5ODL,OE3GHB and DF6NM on 8970 Hz

Very well done.

I have been trying for the past 2 weekends to launch my balloons or kite aerial but the weather
has been unsuitable.

Inspired by ops using just their home aerials I shall give my 40m end fed inverted 'L' another try.

I shall transmit a constant carrier on

8.976 661 7 kHz

for the next few hours in the hope that someone will pick up my signals.

At some point I could try a longer period maybe over night.

...now Markus appears at 17 dB SNR in my "DFCW-60000" window, exactly at 8970.0020 Hz, see http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html

It is remarkable that all the 3 stations use their home antenna, no kites or balloons, TX power below 300 W! This shows what others could do on VLF as well. My distance to OE3GHB is 590 km!

Also it is interesting that 3 QSOs could easily take place in a bandwidth of 10 mHz :-)

It's fun and fascinating, thus not useless :-)
