GO-32 Curiosity Question
by Bruce Semple 06 May '07

06 May '07

I seem to need two different "audio drive levels" when working with the GO-32 bird. When I am just requesting a file to be downloaded I can use one setting. However -- when I go to upload a file -- I need to increase my audio drive significantly -- It appears that I am talking to two different "TNCs" aboard GO-32 -- One handles the file download requests -- and there is a different one that handles the uploads. ... Is this a correct assumption? Just curious -- Bruce WA3SWJ

Q. for antenna experts!
by Jeff Kelly 05 May '07

05 May '07

On another list for High Altitude Balloons a question came up on installing an 802.11 system on board and what antenna would be best on the balloon. Circular polarization came up. Of course low cost - commercially available was key also. Any suggestions on the balloon side for 2.4? I have seen low cost circular patch antennas for 2.4. Is that a good pattern for up to a 100,000 ft source? Guess the balloon side should be LHCP? The balloon payload would be thrown around and spinning in flight. Thanks for any ideas. Jeff KT2K

FO-29 Operation Pause (Fwd from JARL)
by Mineo Wakita 05 May '07

05 May '07

About "Fuji-3" Present Condition and Operation: (Although the normal operation is checked, the operation is stopped for a while.) It is as a previous report an amateur satellite "Fuji-3" (JAS-2, FO-29, 8J1JCS) of JARL. From 21 April, 2007, although the analog system transponder had stopped, we announce you the subsequent present condition. On 3 May, Thu. 16:00 (UTC), We could check an analog system transponder (JTA) of "Fuji-3" was worked to ON and OFF by command from a GS control office and there was no fault in a command system. On 4 May, Fri., we made turn ON the analog system transponder, and the electric power income and outgo were checked. The rate of the shade was 25%, so the electric power income and outgo turned out that it is in a quite severe state. Since the check of the electric power income and outgo, the battery reconditioning, etc. are worked, we do as stopping the operation of "Fuji-3" for a while. Although we cause users much anxiety, we consent-wish-do. In addition, although it may turn ON temporarily an analog system transponder over Japan during an operation dormant period, please refrain from use of transponder such as a loop test and a communication.

Yes, GS of JARL passed at last some command to FO-29, now use only for examination and only over Japan. Tomorrow, JARL will comment the present condition of FO-29, so I will translate it and post it to amsat-bb. de JE9PEL, Mineo Wakita

Or is there a >more simple approach at play? > >73, Bruce >VE9QRP I'm willing to bet they just turn the telemetry downlink on manually, then shut it off before LOS. 73, Drew KO4MA
