Hi all, Maybe some of the stronger MF stations could provide a WSPR signal? In the evening it would help as well... I'm now running a local WSPR QRPPP test in heavy QRN. 2 WSPR instances are running

Hi Eddie, Roger, I remember you were active on MF WSPR some time ago, using a very weak signal. I would be interested to try to receive this again, for testing my RX. If it is possible to become QRV,
Hi Eddie, Thanks. The test is running 24/7. It will just work in the night between us. Tomorrow is fine. G3WCB, F6GEX and HB9CAU are providing useful signals already. Hopefully they will continue for
Thanks Eddie, Looks like a challenge. The first decode may be arround 21 UTC. 73, Stefan Am 30.06.2015 15:38, schrieb g3zjo: On 30/06/2015 00:03, DK7FC wrote: Thanks. The test is running 24/7. It wil

Hi Edgar, What is your RX system for 40 kHz? A 96 kS/s soundcard? And what type of antenna? 73, Stefan Am 02.07.2015 03:19, schrieb edgar: Hi, The result from an audio recording of 40 kHz JJY from ye

Hi Roger, Thanks. There have been plenty of weak signals in the past days. Furthermore there is very high QRN and so much heat that i tend to shut down my Raspi or at least keep the CPU load as low a
