We have not listened to Juno. We only occasionally mount our X-band antenna in focus, so far we have only done that for Voyager-1 the Hakuto-R M2 Moon landing.
Juno's signal was strong, even detectable with 2m dishes, so some amateurs could try.
Maybe @amsat-dl.org (20m dish) has listened before.

Same in Bochum.. shortly after the end of braking and start of pitching maneuver.. 😢

After fixing this mistake, the frequency difference is on the order of 1 Hz. This is about 0.7 ppb, so it is within the accuracy that we could expect for the GPSDO at Bochum. So mystery solved!

The signal can be detected both in the Dwingeloo and Stockert 25 m radio telescopes, but the performance of Dwingeloo is poorer. The observed Doppler spread is on the order of ±0.75 Hz, which is a bit less than the spread model I made.

Oeps! Was haastwerk, zie tijdstip van de post ;) De telescoop kan vrij snel slewen, 1 graad per seconde, in dit geval snel genoeg. Maar omdat de capsule nog heel laag zat, was hij bij ons al op de horizon op het moment dat ze begon met zenden. Desalniettemin hadden we goede ontvangst op de horizon!
