Finally got a little time to play. I'm transmitting on 8270.0 now, showing 600 ma antenna current. Ideally, it runs for the next 24 hours (if I have enough air on the amp!) Ward K7PO Tonopah, AZ
Getting a strong signal at 8270 Hz at Hawley Texas, distance approx 1200 km from Tonopah. http://abelian.org/vlf/tmp/180209a.gif This is almost certainly your signal but there is a large frequency sp

Paul, I think you are correct on the GPS lock. I now recall a couple occasions in the last few weeks where I noticed the GPS unlocked. The problem must be worse than I thought. Tonight (~0100Z) I'll
I made a rough spectrogram from the Hawley recording, http://abelian.org/vlf/tmp/180209c.png The signal is either going off air, or out of this 0.2 Hz band. 8270.0 is a good frequency, nobody else is
Jim, That would be awesome. You can see below when the Texas RX copied me. I'm going out tonight to get the GPS working properly. I'm having a little trouble believing my first test went so well. Not
Paul, Good news/bad news here. I found where some of the local wildlife had been snacking on the GPS antenna cable and replaced it. Now for the bad. I use this antenna on 2200/630/160 meters. I had n
Sorry to hear about the damage but at least it wasn't a complete melt down and burn-out although it sounds like quite a mess. Your signal was doing real well even with the shaky GPS. I was so impress
Testing now from ~0100Z until ?? 8270.0 800 ma Plan is for 24 hours (or until something bad happens!) Ward K7PO/WH2XXP Tonopah, AZ DM33 --Original Message-- From: Paul Nicholson <[email protected]>
Hi Jim, Thanks for your efforts. I had to return to my 2nd QTH, for work in the morning, so I can't monitor anything from here. Hopefully, tomorrow will give results. -73- Ward K7PO/WH2XXP Ward, Glad
A terrific signal at Forest, VA, 3070km. Day and night. A sharp line exactly on frequency. Will post some plots later or tomorrow. So far, no detection at Todmorden... hopefully the carrier continue
Paul, Thanks for the report! You made my day. I'll leave it on for another 24 hours, at least. Ward K7PO/WH2XXP --Original Message-- From: Paul Nicholson <[email protected]> To: rsgb_lf_group <rsgb
Ward It appears that your carrier was easily received in CT last night. Using the same file as Stefan's transmission your carrier (*) was detected immediately at the 0,0,0,0 phase trial ... and impro
Jay, Thanks for the report. After the shaky start a week or so ago, things seem to be working OK now. Fun stuff! I'm already set up for EbNaut tx, but will probably test with a carrier just a little
Jay, Are you in FN31ls? That would make it a 3588km path. Ward Ward It appears that your carrier was easily received in CT last night. Using the same file as Stefan's transmission your carrier (*) wa
Ward Glad to hear a message will be in the works! Some sites have it as ls and some as ms ... we're right on the line. Ls is the one. The actual coordinates are on my website. Jay -- Original Message
Ward A later file produced a better Carrier S/N of 14.65 dB in 35.2 uHz. Daytime files did not produce a decode of the carrier. Jay W1VD WD2XNS WE2XGR/2 Attachment: K7PO022118.png Description: PNG im
