Just a few minutes ago FO-29 was in my range for 2nd time this night (orbit #58964) and it was
active again, strong and healthy !
I heard it clear from 5 degr @ 23:18 Z, over Scandinavia. At 22:23Z came on a new Eclipse
again... however it's obvious that, as I observed very carefully this time, the Satellite has
not any problem also into Eclipse! I did not notice any decreasing of Downlink power this
time, nothing at all. I sent several times CQ on CW and SSB, too. No problem !
Always BOOOMing ! Loud & Clear signal !
I lost the signal at 23:29 (5 degr). It is absolutely normal from my location that.
After my 2nd observation, it's obvious that (my opinion) now the batteries can maintain the Satellite "ON",
even if goes through Eclipses. I don't know how is possible to re-born old-batteries on Space, however...
Congratulations to JARL for that ! Well done !
My compliments Gentlemen... I vail . -

Subject: [eu-amsat] FO-29 is back again !
after Robert-G8ATE's report on Amsat-BB, this evening I tried together with my friend
Dimitris, SW1JGW, a test on FO-29.
Well, yes indeed, the Satellite is active again ! Just after the AOS we heard clear
the Beacon, and then I had a nice QSO with SW1JGW (21:36Z) ! After that I changed
my frequency a bit lower and I had a 2nd QSO with DL6HP (21:38 Z).
Both, Dimitris and I, we were QRP ! 5 Watts for Uplink were enough for excellent return
signals on Downlink. By using QRP we tried to avoid any overloading of the bird.
The Satellite was really Booming, always 55 - 59 with "crystal audio".
However, at 21:38 my return-signal rapidly decreased, but even much lower it was easily readable.
After that I interrupted my TX and I return onto Beacon frequency. Q5 now, but still "clear" !
Later I noticed that on my tracking software, precisely at this time the Satellite came on a new Eclipse !
So, probably the old-Batteries are not strong enough in order to support the same Downlink-power
in eclipse, like that on Sunlight. Also I observed some FMing at this point and I lost the
signal before the LOS, but on this direction I have not "clear horizon" (but High buildings),
so I can't say with accuracy if the Satellite was still "ON" or not. Sorry !
Anyway, the FO-29 is back again ! Great news !
CU on FO-29 !
