Hi Greg.

Yes, the satellite has the transponder on for the whole orbit this weekend until around 20:30 UTC Sunday

Looking at the red graph from the telemetry, you can see the power consumed is the same in eclipse and sunlight. The peaks in the red graph are due to the transponder being used.

curious why you couldn't hear yourself. - Although there is a 10kHz offset on the 70cm uplink and for me it does go at the horizon. Can't hear -5 degrees here.

Good luck for another pass

David

Hi Jim,

Just listened to the Saturday 18:34z pass of FunCube over Northern California. Nice telemetry beacon, but I could not hear anyone (including myself) in the passband. Is it still in Transponder mode, or am I doing something wrong?

Telemetry beacon was at about the predicted 145.935 +/-, and I was listening between 145.950 and 145.970 (and beyond both edges for Doppler) for other stations (none heard). While listening on 145.960 I tried transmitting around 435.140, +/- about 20khz; nothing returned. Antennae are "Oscar class" CP beams, with an RX preamp at the rotor, and full Az/El computer control. Radio tuning was manual.

Not important for this pass, but I did notice that I could copy the beacon to -5 degrees (below the Southern horizon), with freshly updated keps.

Hi Folks,

At approx 21:12 UTC this evening, AO-73 was switched into continuous lowpower beacon/ transponder ON Mode for radio amateurs use during the weekend.

We'll be going back to normal mode at the end of the weekend.

Enjoy!
