LF: To all VLF transmitters

["Mike Dennison" <mike.dennison@ntlworld.com>]

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.
