Hi Peter.
Thanks for your mail. The transponder has been on every day
When and where are you listening?
When: During eclipse, so a night time pass. You should have 3 passes, usually
around 7pm to 11pm local time.
Where: 145.950 to 145.970USB / CW
for additional info, please have a look
Burns,
Sounds good. There are various ways to combine the source files, but they are
all external to
SatPC32. I have just gotten so used to using different groups that my fingers
are already programmed
with that macro. :)
I like the description of groups as aliases! I will steal that for
Thanks to everyone...I've gotten a lot of help from many people, including
Erich Eichmann the author. I thought it would be nice close of this thread
with the model I now have in my head, confirmed by Erich.
Here is what I think I really missed: There is *always* a SatPC32 group
active, and it
The satellite is only in transponder mode when it is in eclipse..
In full sunlight it is in beacon mode only.
Just curious about the overall design goals of this operating mode?
Putting solar energy into and then taking it out of batteries suffers
about a 30% loss in efficiency. All else being
Hi Bob,
Yes the mission requirements are exactly as your last paragraph. We have a
dual mission and needed a simple, autonomous, on board system to make the
change between the two modes. The sunlight/eclipse transition is fairly
easy to detect and forms a valid decision criteria.
The
From Graham earlier in November on the BB:
Hi All,
Yes in telemetry (also known as educational) mode we have around 300mW and
this is a much higher average RF output than when in amateur (also known as
transponder) mode.
Total current drain is therefore greater
Just wondered if I saw this observed/reported already:
When for the Funcube-1 transponder using:
435.140 MHz uplink (LSB)
145.960 MHz downlink (USB)
I still need to add another 10kHz on the uplink (making it 435.150 MHz).
Can anyone else confirm (or counter :-)) this ?
