Does anyone know if it's possible to receive data from Hubble, and if so, what frequency? My guess would be that it is too far out for normal scanner reception but is the data relayed via a repeater maybe? Any feedback would be greatly appreciated.
I believe the TT&C downlink frequency for HST is 2255.5 but there it would appear to relay its mission data via TDRSS. http://www.pbs.org/deepspace/hubble/diagram.html explains a few things about this including "Commands to HST originate at the STOCC and are sent via land-line or communications satellites to the TDRSS ground station at White Sands. From there the commands are sent via the appropriate TDRSS to HST. Scientific data are sent from HST to the STOCC via the reverse path, and then from the STOCC to the STScI via dedicated high-speed links."
It therefore most likely uses the Ku link similar to that used on the ISS / STS to transmit to the TDRSS satellites.
