Hi Chris
Conditions for me last night were terrible, with
0.5 inch railing right across the VLF spectrum, and without the watwerfall
screen I would have seen nothing. However there was a
continuous white line down the waterfall on the frequency you stated, but was
still there when I switched the power off the miniwhip, though slightly
reduced. I decided it must be generated locally, perhaps by the
computer. When I switched on this morning, the screen was nice and
clear, also the signal which might have been yours was missing. My
feelings now are that it was possibly your signal amongst the crap.
This afternoon the railings are back, nearly blasting away the alpha sigs. but
no sign of your white line. My problem is that I find it
difficult to identify any coding which may be on. Like I said
before, if you could regularly key it on/off every few seconds, it would
help, even if occasionally giving an identification blast to please the met
office.
I don't know where the railings are coming from,
obviously some blasted equipment nearby, maybe a large television set, which
would relate to the times seen.
I shall not be on TB tonight as I am expecting a
short visit from my Penzance son.
