Hi Mike,
All right. After the currently running experiment i'll run some carrier
or maybe DFCW-60000. I'll announce it a few days before.
Make sure a 47 uHz window is running to that time, maybe two
Spectrograms, one showing 8270 Hz, the other one showing ALPHA F1,
11904.7619 Hz.
Locking to GBZ or GQD or 1 PPS is a requirement! Maybe Eddie can help
you if necessary.

It is really interesting to follow the activities of those using the
extremely challenging frequencies below 10kHz, but can I make a plea
for anyone testing on VLF to give a day or two notice when announcing
transmissions. Not everyone has a permanent VLF receiving set-up.
I am happy to run a VLF receiver but to do so I must stop my 136kHz
activities, retune the antenna (in daylight), and set up an extremely
slow spectrogram which will take several hours to show enough
background noise to prove that it is working.
There must be other stations who would like to join in with the tests
but are in the same position as me. Sometimes, by the time the
spectrogram displays anything useful the transmission has stopped or,
worse, the transmitting station does not say when he has stopped
transmitting.
Thanks.
