On April 20, the FCC’s Enforcement Bureau issued a new Enforcement Advisory, repeating the admonishments contained in a January Advisory that no licensee or user of the Amateur or Personal Radio Services may use any radio equipment in connection with unlawful activities of any nature.

The Commission specifically cautioned that individuals found to have used radios in connection with any illegal activity are “subject to severe penalties, including significant fines, seizure of the offending equipment, and in some cases, criminal prosecution.”

In addition, licensees should be aware that illegal operation in any service or band, including completely outside the amateur allocations, could potentially disqualify a person from holding any FCC license in any service, not just the Amateur Service.

Any amateur observing a suspicious infraction that might be of illegal or criminal nature should report it to their local law enforcement office or the FBI.

The ARRL released ARLB011 reminding amateurs that updated Radio Frequency Exposure rules become effective on 3 May 2021.

These are the same rules that have been in effect since 1997. The primary change is that amateur radio stations are no longer categorically exempt from performing an evaluation. The RF Exposure limits have not changed.

More details on the ARRL RF Exposure website.  Resources available on that page are links to an ARRL FAQ their RF Exposure and You document, an extract from the chapter on conducting a station evaluation,  forms you can use, and an online RF Exposure Calculator. 

Here’s another RF Exposure calculator by VP9KF that displays the info in a different way including discussion of duty cycle of different modes.

You do not have to submit any information with the FCC.  Simply complete the documentation and file it with your license documents. 

The ARRL states that they will be updating their site with any applicable changes as they are identified.
