Hi Rik Pity ! Could not receive anybody here. And conditions were not bad at all. I was spotting LA2XPA in WPSR at that time I have been monitoring JT9 for some time now and can recall receiving you
Hi Rik, Stefan. Interesting discussion :-) Yes. The problem here is worse, as I'm further away from the center of activity (central EU) and so better Tx is needed to reach here. last night conditions
Hi Stefan, MF Is your remote location using a GHz link to your shack or do you cover the distance via internet? In other words, is it completely your own infrastructure that you are using or are thir
Hi VLF Been struggling with VLF Rx this weekend and found that the RSDN-20 Alpha at 11904,7619 Hz seems to be off air since a few days. Last traces can be clearly seen at Stefan grabber http://www.iu
Thank you for the info Roelof and Stefan We will wait and see if they pay the bill or not ;-) Not much. Added a GPS which will be used to discipline the soundcard And still using MiniWhip and Perseus
Amazing ! Congratulations Stefan. Another brick in your wall of outstanding achievements ;-) Question about the 5kV mains modified transformer. Is it a microwave oven transformer ? Or one of those us
Thank you Stefan I have been following the return closely. Yesterday there were a few short transmissions Playing with my grabber down there. Very close to the 10KHz limit were Perseus is deaf 73 de
Hi MF Finally we managed to make our first QSO last night Signals were loud enought for CW but Alberto had a delay in the PA and so we went to QRSS3 Hopefully he will keep active tonight in QRSS for
Ups ! Sorry. Wrong callsign. Corrected now to EA4GHB ! De: [email protected] [mailto:[email protected]] En nombre de VIGILANT Luis Fernández Enviado el: martes, 11 d
Thank you Stefan. Noted ! I was getting puzzled with this and blaming VAC :-) 73 de Luis EA5DOM De: [email protected] [mailto:[email protected]] En nombre de DK7FC E
Hi Vinny Thank you for the link and the idea. Will try it VAC is a key software in my Rx. I get 6 VFOs from Perseus from 0-500KHz bandwith and the audios are sent to different aplications and instanc
Thank you for the signal Domenico Unfortunately no decode, but this helped me to identify some problems here in my Rx First is the VAC problem. What I get from 11.904 Alpha at 3.5mHz FFT is a bunch o
Hi EbNauters Finally running here an E-field probe connected to the soundcard and 1pps disciplinning VLF signals are weak but I can see 11.904 Alpha at 374uHz stable and right on frequency What I sti
Thank you very much Markus The .USR file is useful, but your detailed explanations are even better to understand what's going on Would worth to add it to your EbNaut utilities So far so good. SL is "
Hi Stefan, VLF And thank you for your all your comments and advices :-) I was already running an SL instance showing the first 24KHz in a fast way to get an idea of what's going on with QRM and known
Hi Stefan The grabber is now showing full spectrum from 0-24KHz https://ea5dom.ure.es/grabber/index.html The Rx is not at Benidorm in the high tower. It is in the roof of a two level house on top of
Hi Markus Thank you again for the detailed explanation To try a decode from Stefan transmission yesterday at 18:00 I have choosen the file 05022225.txt This should contain the 7.9h FFT from 17:58 to
Hi Markus Not your fault ! I did not use your .USR directly. Tried to reproduce the configuration manually Then I did not realize about the different time pattern in the files. Now I understand one m
Hi VLF This weekend could fix the QRM problem with the VLF E-probe. There was a ground loop at the 1pps from GPS The ground of the GPS (and PC via USB) was routed to the audio transformer at the VLF
Congratulations ! Really amazing techniques :-O Add accurate tracking of a (small) dish, and accurate doppler compensation and you will be able to detect the Voyager1 in 8.4GHz ;-) 73 de Luis EA5DOM
