WSPR from JO33ic (the village of Zuidlaren)

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!

WSPR (QRPP) heard on several bands

With the attenuator of 10dB my signal is still heard, even though the distances are less.





This weekend I was active on 40/30/20 meters with the output of 500mW. At this moment I am tuned to 40M, see listPicture of activity on 40M.

WSPR with 500mW

A good friend of my builded a 10dB attenuator. This means that the 5 watts signal from my Yaesu FT950 decrease to approximately 500mW. Today I started on 20M and a few stations heard my qrpp signal.Drawing made by PA1B

The ideas for creating an attenuator did I found on the webpage of Bert, PA1B.

WSPR 20M

The last 24 hours my system is listening on 20M to WSPR signals. When I'm home the system is also transmitting.
At the end of the afternoon and begin of the evening signals from the States en Japan are coming in. In the morning there only a few signals from Europe.

Bezoek vlooienmarkt Rosmalen

Vandaag met een clubje afgereisd naar Rosmalen. Doorstroom bij de kassa ging vrij snel, ondanks dat de route niet helemaal logisch was.

Enige uurtjes langs de kramen gelopen, eerst kon ik mijn boodschappenlijstje niet vinden, uiteindelijk toch onder in mijn jaszak.
Bijna alles kunnen kopen: Helaas zijn de weerstanden die als "2 watts weerstanden" aan mij werden verkocht niet geschikt voor dit vermogen, toch een beetje bekocht. Verder wat BC557/BC547 transistoren, een kastje voor de verzwakker, wat draad en 2 boeken.
Het linker boek kocht ik nieuw en het rechter boek voor slechts
€ 2,-- , ziet er ongelezen uit.
