Very well done.

I have been trying for the past 2 weekends to launch my balloons or kite=
 aerial=20
but the weather
has been unsuitable.

Inspired by ops using just their home aerials I shall give my 40m end fed=
=20
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.

It is remarkable that all the 3 stations use their home antenna, no kites=

balloons, TX power below 300 W! This shows what others could do on VLF as=
 well.=20
My distance to OE3GHB is 590 km!

Also it is interesting that 3 QSOs could easily take place in a bandwidth=
 of 10=20
mHz :-)

It's fun and fascinating, thus not useless :-)
