Paul and Markus, Thank-you for the encouragement and patience, but infortunately the message received does not match the one that was sent, assuminmg the sending was done correctly. Can we try again?
Hi Joe, Your first attempts to cross the pond is certainly more remarkable than my meanwhile almost daily transmissions for the VLF establishment :-) I just assumed that Paul is the only one who can
Yes, I had some doubt with that one. The Eb/N0 was quite good but the BER was high. I'm getting a lot of false decodes, some quite good ones too, This because I'm doing a lot of runs with full phase
Hi Markus, Yes, it did seem valid... But we will continue to try. Tonight a 3 character message, 8K25A polynomial, 464 symbols 55 seconds long starting 2300 tonight and 1100 tomorrow morning. Please
Signal strength seems to be up a bit - Overnight 13th/14th: average 0.11 fT, freq 8270.0070925 +/- 0.5 uHz; Daytime 14th: average 0.085 fT; Overnight 14th/15th: average 0.082 fT; It's been two noisy
Very grateful for the report given the low ERP. Thank-you Paul. I'm playing in my back yard and workshop and trying to get a stable reference to improve the VLF sigs. I'll keep tranmsission going. Th
Daytime 15th: No signal detected; Overnight 15th/16th: Good signal, average 0.12 fT, S/N poor; Daytime 16th: Down in the noise at about 0.05 fT; Overnight 16th/17th: No signal visible, E-field down f
iHi Paul and Joe. Interesting results on VLF . The following may be interesting? I dont know how badly electron precipitation affects VLF though it aligns with the poor results on the 16/17th. The pr
Hi Paul and Alan, Unfortunately there was some arcing in the coil last night and the carrier is off at the moment. Thank-you for the signal strengths and frequencies, Paul. Sorry if this messes up yo
The carrier is on again. After 12 hours at 0.34 A the coils are warm but are not frying. The plan is to keep transmitting tonight and tomorrow. 8270.00709 Hz +- a few ppb, ERP 15 uW 73 Joe VO1NA
Dear VLF, The TX is on with the usual 10 uW, 8270.0075 Hz unmodulated carrier. There is evidence of it crossing the pond on Paul's VLF spectrograms in Todmorden. Thanks for this service Paul. 73 Joe
Yes, just visible. Quite a good amplitude but the noise is so high - http://78.46.38.217/fbins3.html#p=1526436000&b=260&s=fd&m=cardioid&w=r&h=62&z1=0.34&z2=0.64&c=1&mb=669,131,743,171,1 -- Paul Nich
I notice now that you have been on the air for a couple of days, http://78.46.38.217/fbins3.html#p=1526436000&b=260&s=fd&m=cardioid&w=r&h=62&z1=0.34&z2=0.64&c=1&mb=114,144,631,161,1 -- Paul Nicholson
Hi Joe, A nice idea. I will try to produce a spectrum peak from zthe carrier. Just switched to the EW loop, so i missed the first day... 73, Stefan Am 18.05.2018 01:54, schrieb [email protected]: Hello V
Good to hear from you both, Markus and Stefan. Yes, a bigger antenna is needed and more power and a coil that tolerates more voltage... or maybe QSY to 17 kHz! Good luck with the reception efforts an
Hello Joe, I searched for your last nights carrier in my recordings and found an impressive SNR, totally unexpected for this time in the year. See attachment. The carrier reaches 10.97 dB S/N in 39.7
