Hi Clemens and Stefan Thank you for the ideas to improve Rx in VLF Yes the noise background is dominated by 'horizontal' traces, not by vertical traces, i.e. QRM (unwanted) instead of QRN (expected i
Hi Elmer Wellcome to the low bands Long Island, NY. May be you can use a high building tower to install the Tx antenna ? MF/LF antennas is all about vertical section and topload capacity. I’m u
Thank you Stefan The SL instance is updated with the modified USR file. Non stopped, so you can see the difference https://ea5dom.ure.es/grabber/index.html 73 de Luis EA5DOM De: owner-rsgb_lf_group@b
Thank you Stefan Waiting for your config file ;-) 73 de Luis EA5DOM El 12 may. 2017 8:43 p. m., DK7FC <[email protected]> escribió: Hi Luis, I just made some cosmetics, no changes in the signal
Hi all I have been looking for a high voltage tester. The idea is to use it to measure voltage at the MF coil and also playing with transformers for VLF Tx as Stefan explained few days ago I found pr
Hi VLF It is going to be hard to keep this rate of achievemts ;-) Congratulations to all the team involved. Really motivating experiments Indeed harder than EME !! First man used bands revisited with
Hi VLF This morning I found some strange signals at Stefan's VLF grabber, which is not usual http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html Then I found the same signals in my
Thank you Peter At Markus grabber the loops phase indicated that signal was coming from East 73 de Luis EA5DOM --Mensaje original-- De: [email protected] [mailto:owner-rsgb_lf_group@
Hi VLF Just a try here ...... and there is a trce at 954uHz ! :-O Spectrogram added to the bottom of my grabber https://ea5dom.ure.es/grabber/index.html 73 de Luis EA5DOM De: owner-rsgb_lf_group@blac
Signal dissapeared. Modulating FSK ? Need another grabber to confirm 73 de Luis EA5DOM El 28 may. 2017 1:00 p. m., VIGILANT Luis Fernández <[email protected]> escribió: Hi VLF Just a try here ...... a
Thank you Wolf False positive confirmed ! Explanding the spectrogram found a signal at every Hz :-( Local noise, but accurate in frequency 73 de Luis EA5DOM El 28 may. 2017 2:36 p. m., Wolfgang Büsch
The strongest recorded event so far, just 50 years ago Dst =-387nT, Kp=9 for 6 hours Flare flux: 8000 SFU at 2800MHz Dolores J Knipp (Univ of Colorado) recently gave the following talk on the subject
Hi VLF ….. a bit off topic but seems that this is the right place to talk about “almost DC” radio experiments, isn’t it ? ;-) Got news from Juan Leandro. Not a radio amateur (
Hi All What we got at about 9 UTC was an intense flare peak reaching R2 http://www.swpc.noaa.gov/communities/space-weather-enthusiasts Looks like since then I’m getting less ground noise in my
Will be interesting to have a signal in the 36km band, Stefan I'm also running my grabber at 8270.007 with SpectrumLab and 1pps sync The 11904 Alpha is also monitored. Unfortunately still much noise
Hi MF TA season is open J Last night, after some Rx spots from US stations received this days in continental Europe and Canary Islands we have spots from Francesc, EA3AER and me being received by W1T
Thank you Stefan I'm QRV. But it's quite noise here during the weekend :( Let's see if there is any trace in the spectrogram I'll be watching every two hours :-))) PS: AMAZING signal plots by Paul, a
Congratulations Jacek Nill here over the weekend. Too much noise :( Will make a new VLF Rx setup and try in a different place looking for cleaner site 73 de Luis EA5DOM --Mensaje original-- De: owner
Last news from Peter Hi Luis, since yesterday the antenna is repaired. There are now 2 Redpitaya parallel that cover the bands from LF to 6m. They will be on nearly 24 h except when I use antenna for
