Dear group, There is really a lot of WSPR MF activity on both sides of the pond. But not a single TA decode. Why is this so much more difficult than on LF? And BTW did we really made enough tests in
Stefan; I noticed the same thing last year on 500. I found that 500 comes alive when temperatures drop and ground cools. I am surprised that LF works so well with these summer temps. Was 81 F here ye
Roelof - I can confirm its like adding a 50dB attenuator to HF and long range MF/LF signals here. Very fast onset and slooooooooowwwwwer recovery- thats typically from just outside of the Auroral Ova
Last week my sigs came thru a small window early mornings and picked by a very good receiver on the other end. :-) TX timer was on 20min interval, PA100w abt 0.5W erp with short Marconi (50m coiled u
Stefan, I have just been looking at the data as a result of this mornings geomagnetic even. (I have not been following conditions closely ) I notice that there was a Proton Event starting 00:00 30th

Hello Stefan, I study propagation of Canadian NDB's in the range 200 - 520 kHz by means of a PERSEUS spectrum recoding from 200 - 600 kHz. This recording runs every night. The Kyoto Dst has been well
Hi Roelof, Thanks, most interesting! And, last night the local (2000 km range) MF propagation was excellent, really a difference. We were isolated from far QRN due to the bad DX propagation :-) 73, S
Hello Laurence, This time it was exceptional here. I found just one decode from Grindavik, NAVTEX Iceland on 518 kHz. This has never happened here before. However, some very good decodes from Muscat
