I'm in the uk and only a m6 which is what's called a foundation licenses and we are only allowed 10 watts output at the antenna,my question is what power setting should the power slider be set at when using fdv mode,as to stay in our 10watts.thanks
Is this a trick question? 10 on the power slider is ~ 10W output. To measure the actual power at the end of the coax, you will need to put something like a Bird meter to get the real output. You can calculate it based on the coax type to get close, but nothing is as good as seeing it with a meter! Then you can bump it up a few ticks to compensate for your coax and connector loss.
