CHANGE'5-T1 chinese spacecraft on 8436.300MHz. Thanks to ON4DPX for the help to find it.

[EA3EMG @ea3emg]

@ON4DPX ok, thanks for the info. This site is very helpful!

DSN Mars Reconnaissance Orbiter probe just a few seconds before to entering into eclipse behing mars. X-Band Downlink 8.439MHz. #AmateurDSN

[EA3EMG @ea3emg]

DSN OSIRIS-REx Spacecraft. X-Band downlink 8.446GHz just now #AmateurDSN

@HRPTEgor @uhf_satcom Hi, PSTRotator software has an option for DSN tracking probes or you can also try F1EHN with the horizons files from JPL, 73

[EA3EMG @ea3emg]

HNY!! Back again at X-Band. Sanity check with STEREO-A and Tianwen-1 (clearly visible the inverse change of the doppler frequency). 1.5M dish 30dB LNA #AmateurDSN

@MeteoOleg @usa_satcom I had to make modifications to the original rotor clamp to get the best results. The rotor was an SPX2. I replaced the red hall sensors with incremental encoders and reading through the K3NG controller. The system was enough for the 1m dish.Actually this system has passed away.

@MihajloPi Hi, 1.50m offset dish, with the appropiate feed and LNA

[EA3EMG @ea3emg]

DSN Mars Reconnaissance Orbiter probe entering into eclipse behing mars, so the signal dissapears. X-Band downlink 8.439GHz #AmateurDSN

[EA3EMG @ea3emg]

@ZhaoFen37759626 Ok, Tnx for the info! 73!

[EA3EMG @ea3emg]

@ZhaoFen37759626 hello, your tracking system is very interesting. Can you tell me the reference of the reducers? 73 tnx

[EA3EMG @ea3emg]

@Madrid_DSN @BymCt1 Muchas gracias por la implementación!

[EA3EMG @ea3emg]

@EA1IW Hi Antonio. No, all is DIY, everything is metric 2020 including the two hinges.

[EA3EMG @ea3emg]

I have improved the support for the X-band feed this way it allows me to optimize the correct position according to the focal point.

[EA3EMG @ea3emg]

@EA1IW Hola Antonio! Señal fuerte hoy de la Mars Express.
