Sebastian and his team DF0MFG start to operating EME by JT65C. They have small 180 cm dish, Septum feed OK1DFC, LNA 0,4dB N/F with ATF54143 designed also by OK1DFC and TWT PA 200W out. They are producing relatively solid signal with this small setup. Only one problem I have observed. This is frequency stability. You can see how is signal drifting from start to end of period on Spectran picture. This cause problem with decoding. I was receiving them well with value around -22 to -24 dB but waiting more than 4 periods to have chance decoding signal. I am sure that after improving of stability in TCXO will be signal much stable and station will be workable also for other stations.
