I believe if you check the regulations, the automatic area on 80 meters is even narrower at 3585 to 3600.
Because of the poor implementation of busy frequency detection, one can expect much more QRM from automatic stations. Eventually, I expect that the regulations will be written to prohibit operation of any HF operation without human or machine automatic detection. The problem is that the narrower, 500 Hz, semi-automatic modes may operate anywhere in the text data part of the bands. On 80 meters, that would be from 3500 to 3600 here in the U.S. However, good amateur practice and the bandplans would not agree with that wide a use of the bands and a ham doing that could be cited for improper operation. 73, Rick, KV9U expeditionradio wrote: > In USA the FCC set the new auto subband at 3580-3600kHz. > No one should be surprised that hams are using this subband > for auto operation exactly as FCC intended it to be used. > > No one is forcing anyone else to operate non-auto in the auto subband. > Space is available for non-auto data/texting 3500-3580kHz without the > limitation. > > Many of us were not happy when the FCC shrunk the size of the > data/texting sub-band, but we must live with it now. > > There is really no question that auto stations exist and will continue > to exist.
