I worked in January 2016 JT65b MX0CNS, Tom with 80w and a 7el. !! see pic:



And the same QSO from my side

bernd qso






He was -26 on my side, easy to copy with his 80w. I know it┤s not CW but still amazing what is possible via EME! So give it a try, EME is a real challenge and if you have seen traces on the screen it is a thrill to listen in the next step to CW signals bouncing from the moon !!!!!!!!
In Feb Tom was testing even a smaller antenna now a 4el. DG7YBN !
And after 15 minutes or so we completed, he was -28 best here and decoded only in average.

The next qso took us 4 weeks of attempts when Tom was using only a 3el. DG7YBN & 80W. He was -27 on my side, easy to copy with his 80w = 340 W EIRP only!
On Sunday April 10th we completed in 5 minutes, he was -27 best here.




Nachdem ich Tom MX0CNS im Januar mit einer 7el. & 80W arbeiten konnte haben wir im Februar sogar mit einer 4el. & 80W ein qso geschafft. Nach 4 Wochen testen konnten wir den Rekord auf ein 3el. & 80W = 340W EIRP verbessern. Im November habená wir den Rekord nun nochmal verbessert auf eine 2el. & 60W auf Toms Seite. Nun scheint die Grenze des Machbaren erreicht oder doch noch nicht?........

ARRL 2009         5W EME QSO on 432 MHz !!


Before the ARRL contest I contacted Dennis W5RZ because I needed his state for WAS. He worked before HB9Q. We made no sked but he promised to look for me in ARRL contest if he can hear me. But let Dennis tell the story:



I have made only one QSO before on 432, and that was with HB9Q. I knew that Bernd, DL7APV, needed Arkansas on 432 so I decided to see what I could do with low power and a portable antenna. I used two Cushcraft 424B antennas (about 8 wl) and set them up vertically polarized on a tripod. My FT-897D put out about 15 watts and I knew I was losing several db in the feedline. With no preamp, I doubted I would even hear anything. I was surprised to hear Bernd calling CQ on Dec 5th and we managed to make a QSO. Later that evening I worked HB9Q. The next day, I took a better reading of power at the antenna and it was onlyá 5 watts! I found a small amplifier with a receive preamp and put it at the antenna feedpoint. My power output was still only 12 watts but the preamp made a tremendous difference on receive. On December 6th, I heard Bernd calling CQ again with a -14 signal. I asked my wife (N5HX) if she wanted to make her first EME QSO and she worked Bernd easily. I copied him on CW later in the evening. I wish there had been more big stations on the band to test with, but I was very happy to make QSO's with these low power levels. Terrestrial noise is a problem for me on 2 meters and 432 seems like an ideal band for EME.

432 Dec 09-3 W5RZ

W5RZ portable setup with 2x8wl

Dec. 05           DL7APV W5RZ         O-26   O-26              with 5W !!!!!!!!!!!!

Dec. 06           DL7APV N5HX         O-24   O-14              with 12W


Here is the JT65 window the qso with Dennis, solid copy with 5W !!

Pse ignore the wrong time & date I recalled the wav files today.

In contest I had no idea and time to save screen shots !
