The default number for percentage time transmitting in 6 minutes has gone up from 40% to 60% and some antenna gain numbers have increased. It’s had quite a dramatic change to my calculations - and not for the better!

What do you mean " default number " , as far as I understand thats down to your operating habits , certainly on SSB my inputs are 17% for 350w ( s&p contest or DX chase ) and 67% for 90w ( ragchew) which by pure chance  RSGB latest calculator ICNIRP/EMF 1f60e result in the same separation distances. The dBi gain for a 3 elephant yagi has gone DOWN 0.1 .

I’m just pointing out the changes I have seen when comparing the previous version of the calculator to the new one in case someone doesn’t notice them. In my particular case, the gain numbers for a long wire antenna have been increased which has affected the end result of Tx power I can run in order to stay within the 10 watt EIRP max for compliance. I have to use that number for my particular installation as I cannot control general public access to my antenna.

RSGB EMF calculator updated.
Following the update from Ofcom to its guidance “What you need to know as an Amateur Radio user” we have updated the RSGB calculator to version rsgb10a. You can find this on the EMF pages of the website
Please treat this as a beta release and report any problems to m0jav@rsgb.org.uk
Changes

  • The main changes are to implement band dependent antenna gain

  • We have also changed the low power compliance condition to less than 10W EIRP average and less than 100W EIRP peak in line with Ofcom’s change to guidance. The other changes made by Ofcom to its calculator were already in the RSGB version

  • Sundry formatting changes have been made to try to prevent text overflowing boxes reported by some users


The cable attenuation table and the antenna gain table have been left visible (not hidden) so you can help us check the values used.
Work continues on frequencies below 10MHz and using ICNIRP 2020 levels (instead of ICNIRP 1998 levels).
