Ofcom issue new amateur radio licence Terms and Conditions
On Tuesday, May 18, Ofcom confirmed the new EMF licence condition for Radio Amateurs and most other licenced radio users
Licensees need to comply with new rules by:
• 18 Nov 2021 for frequencies at or above 110 MHz
• 18 May 2022 for frequencies above 10 MHz but below 110 MHz
• 18 Nov 2022 for frequenciess at or below 10 MHz
The updated Amateur Radio licence Terms & Conditions with the EMF regulation can be downloaded from
A simplified version of the full guidance and specific advice for holders of Amateur, Ship Radio and Aeronautical licences will be made available by June 8, 2021 at
With the RSGB-Ofcom Calculator it appears Foundation holders with HF stations using antennas such as a half-wave dipole, a longwire or a vertical should find the Average EIRP of their station for the FT8/SSB/FM modes is below 10 watts EIRP so they will not need to bother with a Compliance Distance.
Similarly Foundation holders using 10 watts of 145 MHz FM to an omni-directional antenna with a gain of up to 4.5 dBi should also find their Average EIRP is below 10 watts, so again no need for a Compliance Distance.
With the RSGB-Ofcom calculator you just need to enter the Band, Mode, the Transceiver output power you use (e.g. 10 watts for Foundation), Coax type and length, and select an Antenna type, everything will then be calculated for you. Take a screen snapshot of the results to keep as your EMF Assessment record.
