Installation of the 2m dish. Pointing is not very easy. First tests in CW and SSB was conducted with Bird ad hoc elements.(431-17 , 432-15 , 433-37).
Finally 2w is too strong, Leila is not happy. 500 mw seems OK in SSB.(same level of the beacon). Next step, DATV PA but waiting components.

For another test, I Built 2nd POTY feed. New adjustable frame support finished. But too much wind on the hill. I have to strengthen the support of the 2m dish ... with arms at the bottom of the pipe.
And Construction of new 13cm filter.
Soon, tests…

Transceiver, Up converter, Down converter are stabilized with 10 Mhz OCXO VECTRON 718Y3811 (Adjustable in frequency), powered by 13VDC.
After some tests with a GPSDO, I found such a good result with these OCXOs. Easily found on eBay and much cheaper.
