locked Re: 60 meters: Operating guidelines for FT8

Richard Bertrand Larson

So if I tune my radio to channel 3 @5357.0 mhz with a center frequency of
5358.5 mhz using FT8 . The FT8 modulation scheme is 8-FSK i.e. an 8-bit transmission using 8 different audio. The tones separated by just 6.25 Hz, giving an overall transmission bandwidth under optimal conditions of 50 Hz , so my question is with a data BW of 50hz then with a BW for the channel of 2.8 khz should it not be very easy to be in overall BW compliance ????

I’m not aware of any complaints by the NTIA against radio amateurs for using FT8 on 60m.

The volunteer monitor program nor the FCC are sending out violation notices. I keep abreast of enforcement issues and I’ve asked numerous departments at ARRL. This isn’t a concern with anyone there.

ARRL doesn’t have any awards for 60m contacts. So anyone doing 60m contacts there does it for their own enjoyment.
