1. VLF: Carrier on 8270 Hz (score: 1)

Hi VLF, Since 19 UTC i'm running about 600 mA antenna current on 8270 Hz. A plain carrier. It will be on air for a few hours... 73, Stefan

HiStefan - just turned on the 8270 snapper - looking for you. Cold and clear and relatively quiet this morning here laurence KL7L

Wow, what a signal! Over 0.7 fT, I haven't seen a signal this strong on VLF since your kite experiments several years ago. -- Paul Nicholson --

just turned on spectrum lab (hope this is not an artifact, we'll see then the signal runs for a while). this is with 357uHz fft bins. jacek Attachment: 20170117_1.png Description: PNG image

Hi Laurence, Thanks, i love these pictures. It looks more or less equal here, with that white stuff everywhere. However -30 C is totally unknown here. The lowest was -15 C about. But this winter is a

Hello Jacek, VLF, Are you really sure? The signal generator is turned off? I can hardly imagine that the signal is so strong. Does the carrier disappear since 22:30 or 23 UTC? BTW the antenna suddenl

ok, seems my previous results were too good to be true :) the signal is synchronized via 1pps on the other channel of the sound card and there is some crosstalk between these channels. when zooming o

Hello Paul and Stefan, If 0.7fT at Paul's location means roughly 50uW (conservatively?), does it seem reasonable that if I could confirm (for example) a 39.6N, 77.5W location that enables 1fT/rt-Hz n

Is there a SpecLab usr file for monitoring 5170 Hz ? I would like to monitor the frequency but I'm a total dunce when it comes to tinkering with SpecLab. Tony, EI8JK.
