[amsat-bb] Any satellites using 13cm (2.4GHz) for downlink??

S-Band is heavily utilized by LEO satellites as well as more distant
objects such as the LRO.

One excellent place to start is:


... and as for specific objects and frequencies that I have personally
received, there are very strong signals from the following:

2232245000 - Tiangong-2

2245680000 - numerous CartoSat satellites

2242500000 - numerous known & unknown satellites, a popular TT&C downlink

... TLEs for the first two are available and the signals are extremely
strong.  Activity on 2242.5 is hit & miss - some sats don't transmit on
S-Band 24x7, so it's just a frequency that you can monitor for random
activity if nothing else is around.

Hope that helps!
