Re^2: FO-29 schedule Jan, Feb.
The TX will be ON till the Voltage Controller (UVC) decided to switch OFF. Now FO-29 is still in eclipses.
For example, if the TX will be switched on at 2100 UTC on Jan 16, then it will be switched off by UVC at 21:24 UTC due entering the eclipse. I understand it from the chart below.
Black boxes are the eclipses. Yellow means sunlight (percent of illumination). You can see that FO-29 is not free of eclipses but they are getting more and more shorter.
FO-29 is will be switched on after a eclipse and UVC will switch off if the satellite enters the eclipse (a black box). And you can see the last eclipse will be on Feb 08 at 00:15 UTC -> after then we have no eclipses anymore.
You can also use a satellite software like Orbitron to simulate the orbit and the satellite illumination.

Hello Mineo Wakita
Thanks for all the information regarding FO-29

It didn't switch off :) in JO21ho the pass began on 22:26 CEST (21:26 UTC) and the old lady was loud and clear during the entire pass.
Here is a recording from that pass:

The first 2 minutes there is Beacon CW information and after that a QSO I had with ON5NY.
