[amsat-bb] Re: FO-29 telemetry

[SV1BSX]

 Hello again,

I noticed that the "Bus Voltage" it was too high on my 1st collected 
telemetry. I received also the
next pass, in order to confirm that and yes, the "Bus Voltage" is 
unexpectedly high (23.5V)
comparing with any older telemetry were the Bus-voltage  never was bigger 
than 17.5 Volts.

 So, except the "strange" minus temperature,  have we a new "fake" value?
Or Am I missing something about "BusVoltage"?

>> Hello Folks,
>>                 Is the FO-29 beacon operational ??.
>>
>> I had a listen on the pass at 22:08 this evening but heard nothing.

>> I see from the Carr log that the satellite was operational today but
>> there's no info about the beacon.
