Dear Mark, LF Group, Thanks for the info on reception of the WSPR beacon. It was shut down at about 0830utc. The data from all the receiving stations out as far as TF3HZ at about 1800km is so far qui

Dear LF Group, The WSPR beacon is now (2011utc) running on nominally 503.500kHz, with 1W ERP output. At the moment, it is transmitting 100% duty cycle, although I might reduce that if it gets too hot

Dear LF Group, Good copy of XGJ last night around 0045utc - the signal was visible on and off until daylight. No sign of any Russian stns though. Cheers, Jim Moritz 73 de M0BMU Attachment: dec_2900_c

Dear Mal, LF Group, No. Other "activity" within the 200Hz range would only corrupt signals whose particular 6Hz bandwidth the "activity" was inside. So WSPR beacons could coexist with other signals w

Dear Mal, LF Group, I received your screen shot taken at 2158utc. I see you copied it to the reflector, but it was probably too big an attachment to get through, so I have cropped out the relevant pi

Dear Mal, LF Group, The bandwidth occupied by a WSPR signal is around 6Hz. Even if every station with a licence ran a WSPR beacon on 500k, only a small fraction of the band would be occupied. Practic

Dear LF Group, Quite strong signals from G3YHV earlier sending a beacon signal on about 502.4kHz, alternating CW and RTTY. However, very little copy of the RTTY here - the shift seemed to be about 13

Dear Mike, LF Group, For the "A" mode, the tones cover a range of about 170Hz, plus several hertz for the sidebands on the tones. For some reason, the CW ID is offset in frequency by 470Hz or so on t
