S-band is that part of the frequency spectrum between 2 GHz and 4 GHz. Many satellites transmit at S-band frequencies.
This S-band catalogue includes a significant number of satellites in geosynchronous orbit and a quantity in inclined, highly eccentric orbits (HEOs). However, it is much used for low orbiting satellites also.
The United States Department of Defense satellite generally, but not always, use the fixed channels of SGLS (the Space Ground Link System). Uplinks are in the L-band part of the spectrum with associated downlinks at S-band. Some satellite constellations have almost exclusive use of certain of the SGLS channels (eg - the SDS satellites in HEO and geosynchronous orbit use Channel 9.
Experience shows that actual transmissions are not precisely on-frequency for the downlinks. Some satellites wander around in frequency, sometimes by a significant amount. It seems to depend on electrical power available through the state of battery charge, output from solar panels, or a combination of the two.
The late Ivan Artner produced a catalogue of S-band transmitting satellites that includes several of the satellites to be found in Mike McCants's "classfd.tle" orbital elements file. Ivan's data is acknowledged in appropriate places.

During 2006, Ivan Artner tracked a spinning satellite in HEO, the times did not fit known satellites in that type of orbit - it has been tentatively identified as 90026 (last observed in 2004) but transmissions ceased during the first quarter of 2007 before an orbit could be determined |

90004 (classfd.tle) |
US mult--tasking intelligence-gathering and communications satellite |
CW carrier, oscillates in frequency due to satellite spinning at 5.2s per rev |
Highly eccentric orbit, possibly communications but non-operational, the signal oscillation is probably due to the originally de-spun aerial platform having matched rotation with the satellite body |
