DL3PB Sputnik crosses the Atlantic

Unfortunitely my Sputnik transmitter was not ready for the Sputnik QSO party. After building the transmitter and the two power supplies, tests showed that the oscillator did not work. With no time left for serious trouble shooting, I decided to listen for other Sputniks.
I listened on 21.061 MHz and heard Paul WA4IUC answering the
400 milliwatt signal of the Sputnik Peter DL3PB.
I could copy the signal of Paul with much QSB. Paul used 5 watts into a 7 element Yagi. I could not hear Peter.

Although my Sputnik transmitter is not (yet) working, I feel connected by receiving the signals of Paul, showing that the Sputnik of Peter crossed the Atlantic. hi
If all is correct, the QSO of Peter is good for about 10000 miles per Watt.
A great achivement.

Спутник передатчик in SPRAT

It's great to see the Sputnik clone of Michael AA1TJ, on page 30, in the new SPRAT, that arrived today.
Last month I received the Russian tubes 1Ж24Б and 1П24Б to build the transmitter for the Sputnik QSO party, via Peter DL3PB.
Because I don't have any experience with transmitters with tubes, I first studied the proto type transmitter of Michael AA1TJ. Further I studied the excellent info on the page of Peter DL3JIN .
The last questions that I had, after reading those pages, were answered by
Cees PA0CKV and Peter PA0PJE, when I attended the anual meting of the Benelux QRP Club (BQC) in Apeldoorn .
A week ago I started to build the transmitter for the Sputnik QSO Party.
I progress slowly, because I am tired quickly. I also have to build a power supply. I still hope to be ready at the 4th of Oktober for the Sputnik QSO Party.
