FCC Grants an ARRL Emergency Request to Permit Higher Data Rate Transmissions for Hurricane Relief Communications


The Federal Communications Commission (FCC) has granted an ARRL emergency request for a 60-day temporary waiver intended to facilitate amateur radio emergency communications for hurricane relief. The waiver was adopted on Tuesday, September 27, 2022, and immediately permitted amateur radio operators supporting amateur data transmission for Hurricane Ian traffic to employ a higher symbol rate for data transmissions than the current limit of 300 baud.

In its Order (DA 22-1011), the FCC concluded “that granting the requested waiver is in the public interest. Puerto Rico was recently hit by Hurricane Fiona and Hurricane Ian is predicted to cause significant damage, including disruption to electricity and communications services. Thus, to accommodate amateur radio operators assisting in the recovery efforts, we grant the ARRL’s waiver request for the period of 60 days from the date of this Order to operate in any parts of the United States and its territories impacted by hurricanes. The waiver is limited to amateur radio operators in the United States and its territories using publicly documented data protocols that are compatible with FCC rules, with the exception of the data rate limit waived here, for those directly involved with HF hurricane relief communications.”

ARRL’s request stated that trained amateur radio operators are working with emergency management officials and relief organizations to assist with disaster relief communications in anticipation of the arrival on the Gulf Coast of Hurricane Ian. ARRL sought the waiver for Amateur Radio Emergency Service® (ARES®) volunteers, and other amateur radio support groups working with federal, state, and local emergency management officials to assist with disaster relief.

Pursuant to ARRL’s request and similar to written waivers granted by the FCC in earlier years, to qualify, a protocol or mode exceeding the 300 baud symbol rate limit must (1) be publicly documented, (2) use no more bandwidth than the currently permissible slower protocols (generally accepted to be the bandwidth of an SSB signal, or 2.8 kHz), and (3) be used solely for communications related to hurricane relief.

Section 97.307(f) of the FCC’s rules prevents the use of certain protocols capable of higher data rate emissions in the High Frequency (HF) bands that many amateur stations active in emergency communications preparedness are capable of using. ARRL described that equipment they plan to use exceeds the 300 baud symbol limit and that the higher data rates are critical in sending relief communications. Many use radio modems and personal computers capable of using digital protocols and modes that would permit faster messaging rates than normally permitted under the FCC’s rules. ARRL pointed out that higher data rates can be critical to timely transmission of relief communications, such as lists of needed and distributed supplies.

ARRL also explained that radio amateurs using higher-speed emissions for hurricane-related messages in the US and its territories must be able to communicate with similar stations in the US. They may also need the ability to communicate with Caribbean-based stations that are directly involved with hurricane relief efforts. Additionally, amateurs must be able to communicate with federal stations on the five channels in the 5 MHz band involved with the SHARES network and other interoperability partners on those frequencies.

ARRL also pointed out that the past FCC temporary waivers have allowed such protocols in similar events, including Hurricanes Maria, Dorian, Laura, and Ida, typhoon relief communications in Hawaii, and wildfires in the western areas of the US.

In 2016, in response to an ARRL petition for rulemaking, the FCC proposed to remove the symbol rate limitations. It tentatively concluded that such limitations had become unnecessary due to advances in modulation techniques and they no longer served a useful purpose. That proceeding, WT Docket 16-239, is still pending.


About ARRL and the Amateur Radio Emergency Service®

ARRL is the National Association for Amateur Radio®. Founded in 1914 as The American Radio Relay League, ARRL is a noncommercial organization of radio amateurs. ARRL numbers within its ranks the vast majority of active radio amateurs (or “hams”) in the US, and has a proud history of achievement as the standard-bearer in promoting and protecting amateur radio.

Amateur radio operators use their training, skills, and equipment to provide communications during emergencies When All Else Fails®. The ARRL Amateur Radio Emergency Service® (ARES
®) consists of licensed amateurs who have voluntarily registered their qualifications and equipment, with their local ARES leadership, for communications duty in public service when disaster strikes.
