Hello-Is there any chance of using S Band (2.4 Ghz) being used on any future satellites? I know there are several of us who have a box of down converters and associated equipment, waiting for "something". I know the five & dime is being planed.

The ISS is constantly downlinking on 2395Mhz an Amateur TV signal. Most of the time the camera is not connected, buy you can detect and test with the constant DVB-S blank transmission. See:

The recommended receiver is a "minitouner" which can be used with and without a downconverter/pre amp. The signal is quite strong and there is live video the odd time, mainly during school contacts over Europe. We don't expect it to be used much until the new power supply and radios are installed in the colombus module, but you can set up and test on every ISS pass. Elevation tracking is really a must and a 2ft or 3ft dish with a circular feed helps.
If using a down converter, it would be best to use one designed for digital signals, as sometimes other types introduce errors into the signal.

Hi Bob,
No immediate plans for AMSAT-NA but GOLF will give us opportunities to play with a variety of bands over time so I won't rule it out. Anyway, I still have my K5GNA downconverter and BBQ dish on my array so I'm in a reasonable position to influence a way to put them back into use if I get a hankerin'! :-D
