Alan, The problem with pages like http://www.vlf.it/trond2/15-20khz.html is that I don't know how old they are. And more confusing that GBR is listed as "actrive" MWLIST seems to be more accurate, it
Jurgen, NAA is alive and well! I just checked and it is pounding in here. This is to be expected for a 2MW transmitter that is 257.0987 statue miles (413.76025 kM ) distance from central tower of the
Hi Daniele, Yes i could do that but sometimes there are problems when remote controlling the VLF grabber PC since there are 10 SL instances running, the limit for that CPU. So maybe tomorrow (i'm not
Hi Stefan, Ok, I started it last night, will be only for one day, as I need my Rx for other things as well. No I don't mean the notch function. It's the fft-plug-in that you can create. There you can
Hi Jürgen, Am 25.01.2011 15:05, schrieb Jurgen Bartels: How about 2 min samples 30 min apart for 24 hours? I'm recording every 30 minutes for 2 minutes 0-100kHz Those recordings I later can play back
Hi, just joined this group. After getting my 300m beverage work down to VLF (transfomer & PC-PSU issues) I'm looking on the 10-30 kHz range and compared it against MWLIST. However I now see - a weak
Hello Jürgen, Welcome to the group! About 16 kHz: Sometimes there appear traces at 16 kHz as well as on 8 kHz but these may be signals caused by some alias effects in the soundcard, sampling at 48 or
Hi Jurgen, That's right. I'm monitoring VLF/LF since many years, 24/7. That signal at 26 kHz is a new one, transmitting sporadically since some days. My guess is Greek or Turkey. Most VLF/LF frequenc
Yes Warren it is on again now in full glory I have to see when it went back. Jurgen Bartels Suellwarden, N. Germany hor. Antennas: 11-ele 45-87MHz 13-ele Band-III, 48-ele UHF, FM: 15.11 TV: Winradio
Hi Peter, So I started monitoring just at right time. :-) Thanks ! They are still off now, probably had something in their tea ? :-) Just a carrier 16,0 Khz that was turned on/off. Not 16,2 ! Just pl
Hello Stefan, I use Perseus as the rx, not a soundcard :-) So that rules out those problems. How about 2 min samples 30 min apart for 24 hours? I'm recording every 30 minutes for 2 minutes 0-100kHz T
Hi LVF, my apologies for having quoted out-of-date information. Trond's lists are still valuable in my opinion as they are more extensive and detailed than other similar lists, however I did not inte
Hello Stefan, currently the 0-24KHz window in your grabber shows one of these traces close to 8KHz (circled in yellow in the attached JPEG). Could it be possible for you to read its frequency, more p
Hi Alan, MWList ( http://www.mwlist.org ) contains all tx from 10kHz to 30MHz and is constantly updated by several country editors around the world. All are hobbyist and it's a non-commercial hobby p
Thanks Jay, I will use that also. Jurgen Bartels Suellwarden, N. Germany hor. Antennas: 11-ele 45-87MHz 13-ele Band-III, 48-ele UHF, FM: 15.11 TV: Winradio G305 / Fly2000 + video noise filter & vari
Jurgen Here's a list of stations received over the past year in CT USA ... maybe it will be of some value. Scroll down to the middle of the page for the list. http://www.w1vd.com/vlf.html Jay W1VD WD
Hi Jurgen I dont know the list you quote....if it is a BC station list these are often kept more up to date by monitoring stations. The vlf.it lists Danielle quoted carry a date or 2001 I am sire Tro
Jurgen a lot of the list quoted are well out of date. Dont assume because a station is quoted that it actually exists on that frequency. GBR and GBZ closed years ago and the aerials were demolished.
Dear Jurgen, LF Group, You wrote: - a weak 16,0kHz CW that is slowly being keyed. According to the above list that should be from UK, but its level is too low, unles they use low power...> The info i
