However, the Vietnam regulations, although seemingly the same as ETSI, explicitly state 500 mW rather than the 3 dB reduction from 1 W that's stated in Germany! I'd still probably argue that the difference between 500 and 501.187 is small enough that you can state 27 dB here in the db, rather than stating 500mW. I'm not sure we should make the processing scripts do rounding in this case, perhaps we should, if we decide that we want to ignore the difference of 0.237%? johannes
