Delfi-C3 6th birthday and still working
Hi all,
Delfi-C3 has celebrated its 6th birthday on the 28th of April. The spacecraft is still operational, telemetry only, on 145.870 USB
Delfi-C3 has exceeded its mission lifetime by six times now, and on-board telemetry still does not indicate degradation in performance.
So far, our distributed ground station network (DGSN) has collected 2037513 frames as of today, received by 376 registered radio amateurs and many more on the guest account, using the free RASCAL software. This would not have been possible without your continued support.
Thank you!
Please note that the original team of students has long graduated, and delfi-c3 operations are done by very few volunteers. We continue to monitor the live telemetry in our spare time.

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!

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.

Ha! Working now... Nice contact with W9AE in Oregon. Low pass, so not super strong, but now I can start optimizing things... At the end of the contact, Rx was at 145.960, Tx was 435.155 (both dial readings on my FT-736r).
