Notes
1. For other satellite systems, frequencies of e.g. 5.80, 6.60 or 6.65 MHz can also be received.
2. Main channels with high deviation can also be handled.
3. A de-emphasis of 60 µs, or in accordance with J17, is available.
4. m/st/d = mono or stereo or dual language sound.
5. Adaptive de-emphasis is compatible to transmitter specification.
