There is a great deal of information on that topic. In particular, KA7OEI has done lots of work and published his findings . (TNX CLINT). Thinking about that led me to the discovery that the site websdr.org has nearly a dozen SDRs that listen to the 3 cm band. So, I thought I would make a list here and share it. SDRs Listening To The 3 cm Band http://websdr.suws.org.uk/   One beacon found sending FSCW (Frequency-Shifted CW) and an unidentified digital mode having four discrete frequencies. http://maxiplaya.dyndns.org:8901/  Nice CW beacon on 10368929.65 sending chirpy code. http://ea1rj.cloudns.cc:8888/  No beacons detected. http://erc-websdr.esa.int/  No beacons detected. http://websdr.fvzr.ch:8901/  Beacon at 10368086.74 sending unidentified digital mode.
