The 180 MHz transmissions are similar and appear to be continuous for the active life of the vehicle and the same is true at 480 MHz. 180 MHz carries two bands of telemetry and a pair of further carriers. In the case of Fengyun, the telemetry bands are 5 kHz each side of the main carrier with the other carriers at 10 kHz away from the main one. The CBERS/Zi-Yuan/Jian Bing satellites have telemetry bands at 20 kHz and the additional carriers at 40 kHz either side of the main carrier. At 480 MHz the transmission is a simple CW tone.

CBERS 1, a joint Chinese and Brazilian project, also was also reported to have a transmission frequency near to 462.5 MHz, probably to trigger transmissions from remote data collection platforms monitoring climate conditions at sea or in relatively inaccessible land areas. The two CBERS 2 satellites were designed to carry out a similar function. No transmissions at this frequency have been reported by amateur trackers.

Not all of these frequencies are currently active and the list includes historic frequencies - specifically the HF ones used by China's first two satellites. During 2008, some of the S-band frequencies from China's satellites came into the public domain. They too are listed here although not all have been tracked from the Zarya station.

With the 2010 May demise of CBERS 2B, Fengyun 1D became the sole occupant of the 180/480 MHz coherent frequency channels.
