Hi Greg, KO6TH
For the history no OSCAR satellite carried on a Mode-L Beacon.
OSCAR-7 carried on a Mode-S beacon on 2304.1 MHz built by the San Bernardino Microwave Society but it was never officially turned on because of international treaty constraints (bandplan) so that it was not receiving the autorization by the FCC

I believe it was Oscar-7.
Someone years ago told me that one of the early amateur satellites had a mode-L beacon, but because the rules changed, it was never turned on. I haven't been able to verify or disprove this story.

There are uplinks around 1267 to 1269 MHz. Is it due to possibility of interference with commercial/military/aeronautical systems?
