There has been a lot of discussion about this on the GQRP club and VMARS reflectors.
In the Ofcom document: https://www.ofcom.org.uk/__data/assets/p...ersion.pdf
It clearly states, on page 3: Equipment transmitting below 10 W EIRP automatically complies.
I am not going to do any worrying until the final version is published. I am in the fortunate position of being in a rural location with no immediate neighbours but did a basic check using this calculator: https://www.vk5dj.com/VK3UM%20EMRCalc%20...nstall.zip. I am unable to use the Ofcom calculator as it uses Excel, which now requires a subscription. Without putting in any aerial gain or feeder losses my max 300W on HF on my long wire which has a minimum height above ground of about 6m it is acceptable to stand directly below on any HF band, unless you are more than 3m tall.
I think that the problems with compliance will be with high power mobile setups and demonstration stations at fetes and other public events, again if aerials are mounted on tall towers, there should not be a problem.
