I check the JARL FO-29 command station report and found the problem on temperature data. JARL FO-29 control station reports the temperature telemetry data has problem but another data is normal.
Here is sample of telemetry at 19th September. This data show two temperature data problems. 1A 1B 1C 1D 2A 2B 2C 2D 3A 3B 3C 3D 4A 4B 4C 4D 5A 5B 5C 5D 6A 6B 6C HI HI 22 E2 88 D5 8F 05 05 25 00 24 01 01 82 62 94 94 B0 73 F7 F4 BD BC B7 HI HI 22 E2 88 D5 8F 05 05 25 00 24 01 01 81 44 98 96 F0 8A F7 B4 FD BC B7
5C-6C show temperature data. 5C shows F7. F7 means -14 degrees. -14 degrees can't be happening from previous data. 1st 5D is F4 and 2nd is B4. F4 means -12 degrees and B4 means 12 degrees. The temperature is jumping -12 degrees to 12 degrees on one pass. This also can't be happening. FO-29 is sending wrong temprature value as telemetry. I guess temprature sensors or somethings have problem.

Greetings,
Does anyone know if there are problems with FO-29's telemetry system? The structure
temperatures seems to be very cold during the daytime portion of the passes here, even allowing for the long eclipse periods. All four structure temperatures are about -12 with one structure temperature jumping to +13 on one pass.
DK3WN's 6 Oct captured telemetry on his web site blog page seems to confirm these very low
temperatures at least on that date.
Anyone have any other information on this?
Thank you.
