Chris, Jim, congrats from me too. Based on the locators distance would be 38km (centre to centre locator square). About parallelling the balloon antenna and inverted L: as Stefan points out it would
Likewise. Nothing here in IO90IV58 at 145km. Perhaps not too surprising considering Jim's measured levels. Andy www.g4jnt.com On 31 December 2010 19:18, Gary - G4WGT <[email protected]> wrote:

The balloons are still holding up. I'm transmitting 'XIZ' at QRSS600 QRG: 8.971 846 kHz The aerial current is down for some reason although the system's resonant. 73 Chris G3XIZ
Congratulations Chris! I will have to add this new UK VLF record to my sub-9kHz webpage. If Jim can copy then I should be able to as well with a better set-up. So pleased for you. Brilliant. 73s Roge
Well that's its limit. 8137Hz sampling, 2M FFT for a .0039Hz bin size. Will leave it running in the hope the frequencies displayed are as it says they are - not in a position to do a frequency-cal
Dear Jim, Chris, dreamers, very happy to read this, well done both! I had shifted the display range of my grabber a few times to your frequency, but unfortunately no traces in Bavaria yet. However I
Dear Chris, LF Group, I seem to have a trace on your frequency - see attachment. SNR is currently around 15dB with 1.5millihertz FFT resolution. It definitely wasn't there before ;-) Cheers, Jim Mori
Nothing here. But with 15dB S/N at Jim's in a tenth of the bandwidth I'm looking it, and at at least twice the range, probably not surprising. I'll try going narrower, but have never tested the
Yes congratulations from me also Chris. I'm only 11km away but not a peep here. Must have a six inch nail across my antenna. Happy new year to all. 73 es GL petefmt I support www.NotSpotTelecom.Com y
Dear Chris, LF Group, The signal disappeared some time around 1520utc - the complete trace is shown in the attachment. I made an estimate of the field strength of your signal by injecting a test sign
Chris, This sounds good. Trying in 600 is a good starting point and a 50m vertical is fine too. How big are the balloons? Do you use helium or hydrogen? ;-) Using 0.2mm diameter wire may cause some
LF, I am transmitting VLF at present (since 09.00Z) Freq: 8.971 885 kHz Mode: QRSS-10 Ant: 40m inverted 'L' - height 10m Ant current: 0.15A It is too windy to launch the balloon aerial but I shall ho
Congratulations to the new record Chris, Jim, What is the exact distance? Some 10 km i think. http://no.nonsense.ee/qthmap/ Chris, can't you use the inv-L and the balloon antenna in parallel? This lo
