Signals +/-11MHz from the centre must be at least 30dB\ndown from the carrier. Channel 1 is at 2412MHz.\n\nTaking into account Doppler, the recommended S1 coordinated frequencies will\nbe at the bootom end of 2400MHz without the possibility of OOB emissions on\nEarth due to Doppler.\n\n73, Howard G6LVB\n\n", "attachments": [] }
