More transatlantic decodes from the three European autodecoders have been added to the attached list. In contrary to my first optimistic notion, Stefan's simultaneous transmissions did seem to affect decodes from VO1NA at DL0AO and DF6NM. Despite the 63 Hz frequency spacing, there is obviously considerable desense and spectrogram brightening, presumably mostly from noise blanker interactions. Stefan, may I suggest using opposite time slots for America and Europe, i.e. VO1NA starting at hh:00 and DK7FC at hh:30?

Dez 2018 19:00 Betreff: Re: LF: LF and VLF EbNaut The attached file is a summary of our (auto)decodes during the last four nights. For comparison, I have also ripped the spots from Domenico's decoder and entered them in a separate column. Last night DL0AO was slightly weaker than normal, presumably because the Perseus receiver has temporarily been switched from the usual north-west beverage to an omnidirectional miniwhip. Here I have one old Win-XP computer for the LF and Loran grabbers and the opds detector. The autodecoder is running on another machine and accesses the fft.txt file through Windows fileshares. An autodecoder for VLF - sounds like a nice idea. It may need some tinkering because the opds-driven scripts cannot be used directly, but there will be a way.

My LF-RX-PC is just to busy with all the SL and WSPR and OPDS32 instances... I would need a better PC or export the txt files to the server and then do the job on another PC. This may be a project for the future... Markus, what about an autodecoder at DL0AO for 8270.1 Hz? :-) 73, Stefan PS: I tried to decode the message of IK1HGI but obviously it was an unmodulated carrier so there seems to be a problem with the keying.
