Can you please tell me which of these modes are functional and which are the most active (are there any which will never be operational)?
- FM U/v repeater
- FM V/u repeater
- FM L/v repeater
I'm mostly interested in the FM L/v mode (145.800/1269.650 MHz). Is there any equipment on board of the ISS? Has it ever been active and if yes has it been functioning recently?
