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.
Parallel signal showing on screen UT3LL which
was calling me together with DF0MFG.
