Congrats Markus and Paul for this achievement ! I think you used a GPSDO with 10 kHz output on both ends - Thunderbolt, Trimble, or similar ? (still thinking about a simple but reliable, non-GPS solu

Jacek Tnx for your suggestion but I prefer CW or maybe QRS3 anything else is too slow for me. If someone can generate a few watts erp for me to make a QSO then I could get interested but not QRS 6000

Dear Mal, LF Group, If you look at it more generally, this experiment shows that anybody with access to an ordinary PC and a few simple homebrew bits and pieces can measure signal frequencies within

Hi Wolf, Paul was using his own dedicated receive software, with timestamps based on GPS 1pps pulses. For transmitting, I employed SpecLab's signal generator, with samplerate tracking to 10 kHz from

Dear Wolf, Markus, LF Group, I have been doing an experiment over the last couple of days to see if it is practical to do this kind of reception with just the Spectrum Lab "frequency compensation" fa

Jim This looks like a lot of trouble for no real practical purpose, other than maybe get a glimpse of a carrier an odd time on 8970 Kcs The possibility of a real time QSO on this band over any distan

Dear LF, I am very happy to announce that Paul Nicholson in Todmorden was clearly able to detect each of my three test transmissions. His detailed and most interesting report is at http://abelian.org
