Delfi-C3 heard by anyone recently ?
I did not hear Delfi-C3 yesterday evening, and also not this morning (Sat) during the full sun / max 90 degrees elevation pass.
Btw I also scanned the other 2 mtr downlink freq.
For me this is new, that the sat is totally quiet during entire passes.
Did anyone hear this sat recently ?
ps: would be nice to have, like for example we have it for PCSAT and ISS, a realtime website where the latest received packets are visable. then I would see eg that last reception was 2 hrs ago over US by K6xyz(for example).

Hi Henk,
Listening now (1121Z) but nothing heard from Delfi either.
73, Dave.
I heard 145.930 PSK signal at 1240z 17th May.

Same here Dave,
Also here nothing during the next (1120utc) pass: - not on 145.930 - no beacon on 145.870 - tried the transponder mode (70cm uplink) but that also seems OFF - do not know how the emergency mode would sound, but didnt hear that either

During the 15 degrees pass this evening I did hear the FM packets, in the noise, but they were there !
Hopefully during the next pass signal is stronger and I may be able to decode them.

During the 89 degrees pass the signal was stronger.
Using RHCP 2x8 elements, no pre-amp, I heared many packets, but could decode all of them ... yes I do need a pre-amp :-)

15 seconds inbetween each burst, this is how it sounds (20 seconds sample): http://home.vianetworks.nl/users/hamoen/pa3guo/cute_17_21may08_2020utc_pa3gu...

Hi Henk,
Delfi was active with telemetry on two ascending passes last night with some audio distortions and breaks in-between. Copied and forwarded data to Delft TU. Will listen again this morning.
Hope this helps,

For me this is new, that the sat is totally quiet during entire passes.

ps: would be nice to have, like for example we have it for PCSAT and ISS, a realtime website where the latest received packets are visable. then I would see eg that last reception was 2 hrs ago over US by K6xyz(for example).

Hello Henk!
Delfi usually wakes up normally when it have full sun but recently the processor (?) gets stuck earlier and remains quiet for the whole full sun pass. In the last pass yesterday evening I heard telemetry couple of minutes at the start but then again total silence in the middle of a packet frame. There is something ill behaviour in the satellite. It does not restart before eclipse reset. The frequency has been 145.930 all the time.
The next good possibility to hear Delfi awake is 19:07 UTC when Delfi gets full sun and we are just in the footprint.
