Yes used the RF Browser. I only got about 5mW/m2 even at 14.2Mhz 100W and 10ft from the antenna. I have tried using the software to download the RF browser data but it does not seem to be recorded. Also only power and no frequency information so I cannot be sure it is not my mobile phone or the wifi.. Not sure the GQ meter works for lower frequencies. I also tried it on 433Mhz at 10W into 1/4wave. Hard to get close to antenna but at about 20ft away the wifi was clearly stronger.. I cannot see that I could prove to the inspector that I am within the new licence limits for radiation. I have till mid April before the new licence ammendments come into force. All radio operators civil/military etc are going to have to comply. Any ideas welcome.
it is radiated power you are looking for? If it I think the best is to evaluat it with modelisation and calculation based on your antenna diagramm, configuration and Tx power. Done by an radio amateur it should be admissible by the authorities in case of control.
or with a RF detector specialy calibrated to 20m band. otherwise you will only have one chance to be wrong especially since we are on the edge of the bandwidth and bandwith qualification is not defined and must not be at all at -3dB.
Mastery is acquired by studying, with it everything becomes simple

You will not need to "prove compliance" but just that you have made a reasonable assessment and the expected levels are below the published exposure limits. The best and easiest way of doing this is to make calculations using the published OfCom and RSGB calculator spreadsheets; if these do not give a positive outcome (they are quite pessimistic) then a more detailed assessment will be required.
Measuring the levels you are generating will be extremely difficult with the equipment available to the typical radio amateur, even with the appropriate test equipment it is not easy.
