Weak Signal Propagation Reporter (WSPR, pronounced:” whisper”) is a protocol developed by John Taylor, K1JT in 2008. It’s one of the many protocols used by radio amateurs but WSPR is a special one. The “Weak Signal”-part refers to signals being transmitted with a maximum power of 5 Watt (37 dBm), what still is regarded as QRP. But you can use much less then 5 Watt. Use more power is pointless, because it removes the accuracy of the “Propagation Continue reading

On air this weekend with PSK-31
After some juggling around with Ham Radio Deluxe and HRDlog.net the last weeks, this weekend I let Digital Master 780 (as part of Ham Radio Deluxe) running in the background doing PSK-31 when I was studying. Every now and then I’ve made a QSO.
I must say, it actually runs quite smooth now. Little struggle Continue reading
WSPR on 80m
Last night I leave WSPR on for the whole night to see what happen. According to propagation rules, the best opportunities on 80m should be around the greyline. In the evening that means in western Europe I should get signals out of the east and in the morning I should get signals out of the west. A little disappointed I was this morning when the only thing I saw is stations from Europe. Could it be my antenna? Bad propagation on 80m? Not enough WSPR-station on the air? I guess my S9 noise level on 80m don’t help much.
