Paul; It appears to me that your 60 second bins has it! I see A and B very plainly. Your RX capability is phenomenal!!! Warren Zeigler told me of your history of VLF receptions. I will be running in
Markus; I will slow things down in hopes of improvement-Bob From: [email protected] To: [email protected] Date: Sun, 2 Mar 2014 17:36:42 +0100 Subject: Re: LF: Would slower QRSS help? B
Paul; Jay and Stefan and you suggested I should transmit carrier for 1 hour on 29.49900 then move up 10 MHz [29.49901] for hour and back again a few times and then will start QRSS180. Does that make
Stefan; Thanks for your help. Your site also helped me get tuned up and good ant current [now up to 3 amps]. Still have a bit more to go as corona hasn't set in too bad yet. I soldered on one "ball"
G; I plan to manually change freq 10 MHz top of hour for couple three hours is all-should be no trouble-Bob From: [email protected] To: [email protected] Date: Sun, 2 Mar 2014 19:42:
Stefan-yes .010 [10 milihertz] of hertz-2949901 then back to 29.49900 next hour-etc-Bob Date: Sun, 2 Mar 2014 20:59:57 +0100 From: [email protected] To: [email protected] Subj
Bob, definitely yes! I would suggest slowing down by a factor of three to five, ie qrss-180 or even -300. 73, Markus (DF6NM) From: [email protected] Bob Raide Sent: Sunday, March 02, 2014 4:16 PM T
I guessed wrong and Markus suggests a faster spectrogram. This one is in 60 second bins http://abelian.org/vlf/tmp/29499_140302h.gif And in 30 second bins http://abelian.org/vlf/tmp/29499_140302i.gi

Good luck. After last night's test maybe a few more receivers will be listening on 29499 Hz. I'm sure this signal will go a lot further than UK. It counts as a strong signal here and there is 10 or
Bob, There are no more band slots left in the psk-map , we have used them all up , so your flying solo on this one ! Could be a job for Op4H , but the decoder is set to 8K .....not a problem for a SD
Hello Bob, Just to avoid misunderstandings: I guess you mean 10 mHz, not 10 MHz? 73, Stefan Am 02.03.2014 20:47, schrieb Bob Raide: G; I plan to manually change freq 10 MHz top of hour for couple thr
Just added a 3.8 mHz (aka "600") window for 29.499 khz to the bottom of my grabber: http://www.df6nm.de/vlf/vlfgrabber.htm. Don't have much hope of seeing anything here. But if a miracle should happe
Bob, nothing at all in Nuernberg last night. There seemed to be no diurnal change in the background noise level, showing that my receiving setup is not sensitive enough yet. Apparently the current LF
Hi Markus, Since I also "suffer" from insufficient bandwidth for a link to my remote receiving site: What about converting the signal down to 'easily managable audio frequency' (low enough for yet an
