A couple more recent catches on 8.4GHz...

This is my current best 'dx' at 709 Million km away, not particularly strong, this is Doppler corrected.

Juno Spacecraft at Jupiter 24/3/2018

MRO with Doppler correction, very loud signal.

Mars Reconnaissance Orbiter 24/3/2018

Mars Odyssey with an attempt at using jpl spice software to calculate doppler correction, not working correctly but easier to detect the signal.

Mars Orbiter 1 (Odyssey) 1/4/2018

A new one on 16th April, Hayabusa2 has come back to life now it's getting closer to Ryugu. Thanks to DF2MZ for spotting it was active, it was quite a weak signal!:

Hayabusa2

Still more to look out for but not quite as easy to find now!

More work to be done on using the JPL NAIF SPICE utilities, there is no up to date tracking info for some spacecraft on Horizons.
