The FCC Commissioners have unanimously voted to amend the Amateur Radio Service rules, replacing the baud rate limit with a 2.8 kHz bandwidth limit, allowing for greater flexibility in data communications. The FCC aims to incentivize innovation and experimentation in the amateur radio bands by removing outdated restrictions and allowing licensees to use modern digital emissions. The ARRL had requested the change and agrees that a 2.8 kHz bandwidth limitation will permit additional emissions while still protecting the shared subbands. The FCC is also proposing to eliminate similar restrictions in other bands and will seek public comment on these proposed changes. This change is expected to benefit emergency response communications and encourage further development of spectrum-efficient protocols.
