Just had my 1st 2way SSB qso via Ao-73 with Keith ZS6TW. Strong s7-9 without p/amp and excellent SSB audio.
Congrats to the team !

Great!
Congratulations. I guess we have to wait until the sat is in the "dark" to use it here in NA.
Just wondering why you would activate the transponder without having power through the solar panels and consequently discharging the batteries (unless that's the intent). Maybe I am missing something....

Would the transponder mode potentially have lower average power consumption than full power telemetry mode?
In full power telemetry mode, it's putting out 300 mW the whole time. In transponder mode, it's only putting out 30 mW + whatever it's taking to relay the signals it's receiving. The transmitter would only be putting out full power when it's in use.
Unless my thinking is completely wrong here...

Good point.
Now from what I read they are running the telemetry mode at the same time with lower power.
More food for thought :-)

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 when in educational mode. This is convenient because we had planned that educational mode would be more useful when the spacecraft is in local daylight - ie schools would be more likely to be open. This is the primary mission of course. Also amateurs often have to work during the day so would appreciate the availability of the transponder during the local evening passes.
We were not, before launch, 100% certain that we would have a good enough power budget to run the transponder during every eclipse period but, at the moment, this seems to be ok - we still have quite a positive power budget.
Its a bit late here and we are quite tired after three very hectic days but I hope the above explanation makes some sort of sense:)
best 73

Hi,
Yes you can see that if you look at the realtime pa fwd power in eclipse it varies quite a lot.
Ingore the reflected value error.

Hello to all!
I just had my first two - way contact via FUNcube-1 (AO-73) with Drew, KO4MA.
The signal was very strong and stable, the SSB audio was excellent!
Once again, congratulations to the FUNcube-1 team!
73!
Hector, CO6CBF
Hi Steve;
Yes, that is the intent. The primary mission is STEM outreach with the beacon in sunlight.

Just had 3 qsos on the new bird. The signals were really strong.
