Re: Packet rates HF/VHF/UHF under part-97


Yes existing VHF/UHF rigs lock you into one modulation type for 9600 bps. Maybe in coming years we'll see some fully programmable SDR transceivers for those bands.

Also on the horizon will be the FCC looking at Part 97 Regs. Given that the FCC considered the Regs out-of-date and wanted to completely rewrite them back in 1977 (Docket 20777), but was stopped by amateur protests, it's a safe bet that 40 years later the new FCC administration will also consider them in need of a major overhaul.

This year's modernization of Part 95 Regs (GMRS, FRS, CB) shows which way they are likely to proceed - Deregulation - scrapping of unnecessary rules.
