Hi All,
Following suggestions of my friend Mak, SV1BSX I tried FO-29 this night 27 july during the South bound orbit 58978 when the AOS for me in JN70ES was at 00:06 UTC and FO-29 was in sun light.
I was alone into the passband and my return signal was very strong above my noise floor with appoximately only 10 watt on a 13 dBi crossed yagi RHCP / LHCP (about 200 watt EIRP)
The SSB return was very clean and without FMing with the usual need to switch RHCP to LHCP time to time to get the best signal strength
At 00:15 UTC FO-29 started to experience the eclipse as per InstanTrack but no signe of reduction of my return signal or FMing was noted.
From 00:15 to 00:21 until my LOS the satellite was over Africa and well
in full eclipse for about 6 minutes but my own return signal was still clear ad strong without any signe of FMing so that it seems that the battery are working and as far I know the satellite performance seems to be nominal.
The CW beacon was ON all the time but it should be necessary to decode the TLM to get the actual parameters ( I think IW4DVZ can do the job with his suitable software )
The transponder is very sensitive as it was as new so that refrain please to use high power because 200 watt EIRP is more than necessary.
I tanks very much Mak SV1BSX for sending to me the results of his experience yesterday confirming the results that I got this night both confirming that FO-29 seems to be alive and well.
We don't know what JARL did to resurrex this beautiful satellite but until she will last we have another real CW and SSB satellite to work.
Congratulations to JARL

Hi Mike, DK3WN
Tank you very much to decode the FO-29 telemetry. It seems that all parameters are nominal and the batteries are charging but it should be necessary to compare the actual performance with some old telemetry file that you probably have available in your archive.
Please let us know

Hi Mike, DK3WN
Your FO-29 telemetry of Feb, 2006 at 1614 UTC demonstrates that actually FO-20 is working nominally.
Unfortunately despite the boombing signals there is small activity on this satellite and to day the only station I have worked in SSB during all the South-bound and North-bound orbits were Rolf, DK2ZF , SV1JGW, EA3DME and 2E1EUB
Tanks for your help

Hi Domenico, i8CVS
last night I collected the Telemetry from FO-29.
Date 27 July 2008, Orbit #58990. AOS 21:27, TCA 21:34, LOS 21:41.
It is very interesting to point out that, the most part of TLM collected into Eclipe ! If I am not wrong, just the "Data1" is on Sunlight and the rest DATA on Eclipse. At 21:32 the FO-29 came on the dark, 2 minutes before the TCA.
The confirming of Sunlight on "Data1" is obvious also by Solar-Panel Current (= 1000.0 mA). Also the battery has the biggest Voltage (16.4 ). In the next "Data 2,3,4, 5 & 6" where the FO-20 was on Eclipse, the Solar-Panel Current is just 9.8 mA.
However, the battery voltage is droped down from 16.4 V (Data1 on Sunlight) to 14.2 V (Data 6 on Eclipse). That means 2.2 Volts lower in about 5 mins. I can't say if that is normal or not. It's just my notice and probably is OK that but, it should be very interesting if we can find an older TLM-Data into Eclipse in order to compare it with this one.
Finally, the following data are 100% OK. As you know dr Domenico, I am "old fashion" CW operator by using pencil and paper, however I recorded my reception and I confirmed it twice, in order to eliminate any possible fault.
Here is the collected Telemetry DATA:

Hi Mike, DK3WN
Tank you very much to decode the FO-29 telemetry. It seems that all parameters are nominal and the batteries are charging but it should be necessary to compare the actual performance with some old telemetry file that you probably have available in your archive.
Please let us know
Tanks and 73" de

Von: [email protected] [mailto:[email protected]] Im Auftrag von i8cvs Gesendet: Sonntag, 27. Juli 2008 06:08 An: AMSAT-BB Cc: Francesco Grappi Betreff: [amsat-bb] FO-29 is alive and well
Hi All,
Following suggestions of my friend Mak, SV1BSX I tried FO-29 this night 27 july during the South bound orbit 58978 when the AOS for me in JN70ES was at 00:06 UTC and FO-29 was in sun light.
I was alone into the passband and my return signal was very strong above my noise floor with appoximately only 10 watt on a 13 dBi crossed yagi RHCP / LHCP (about 200 watt EIRP)
The SSB return was very clean and without FMing with the usual need to switch RHCP to LHCP time to time to get the best signal strength
At 00:15 UTC FO-29 started to experience the eclipse as per InstanTrack but no signe of reduction of my return signal or FMing was noted.
From 00:15 to 00:21 until my LOS the satellite was over Africa and well
in full eclipse for about 6 minutes but my own return signal was still
clear
ad strong without any signe of FMing so that it seems that the battery are working and as far I know the satellite performance seems to be nominal.
The CW beacon was ON all the time but it should be necessary to decode the TLM to get the actual parameters ( I think IW4DVZ can do the job with his suitable software )
The transponder is very sensitive as it was as new so that refrain please to use high power because 200 watt EIRP is more than necessary.
I tanks very much Mak SV1BSX for sending to me the results of his experience yesterday confirming the results that I got this night both confirming that FO-29 seems to be alive and well.
We don't know what JARL did to resurrex this beautiful satellite but until she will last we have another real CW and SSB satellite to work.
Congratulations to JARL
