During the Easter weekend (Saturday April 3 to Monday April 5) I did some WSPR experiments from JO33IC (Zuidlaren) and made a 2 way QRP QSO on 40M.
My station is a Yaesu FT817 with a 10dB attenuator. The antenna I used is a ZEPP for 30M.
On this band I had all the WSPR experiments. This antenna is on the attic and a part outside.
The CW QSO, I made was with Will, GM0HKS. The nice thing about this QSO was that Will worked with a homemade transceiver of Howes. I builded this transceiver about 10 years ago but my transceiver is for 20m. At that time I had several qso's with it. Will has a sidetone in use, he goes for me to find the schematic.
The experiments with WSPR had only played on 30M. I felt that the propagation was not good and was afraid that they didn’t heard my 50mW signal. First I switched to 100mW and it went. Later in the day my 50mW signal was heard. Distances were between 600 and 1200 km.
Saturdayevenening was the longest distance when I saw on the WSPR site that 4X1RF in KM72LS heard my signal for 2 periods. A distance of 3186 km, and this with only 50mW!

630M 474.200 WSPR - Terug op 630m ontvangstmatig De propagatie 630m is nog steeds vele malen slechter dan in de begintijd van deze band. Komt het nog weer goed met de lage band...
