Hi,
one of the interesting HAM radio topic in Europe now is the use of the new
geostationary satellite Phase-4A (QO-100) for analog and digital modes via a
2.4/10 GHz transponder.

=======================================
... and Time-Nuts may be interested in some oscillator measurements made by
Daniel Estévez showing some unexpected steps. His blog is here:

It's a fascinating story, and may not yet be complete.
Daniel is a GNSS Engineer by occupation.
Cheers,
David GM8ARV
