There is a long standing myth that power by itself creates "poor signals" which has, unfortunately, created a vast legion of "power cops" who have taken it upon themselves to chastise everyone on their waterfall with a strong signal, assuming that everyone that is strong or has what appears to be a "bad signal" are automatically running "too much power."
I received an email from one such individual just a few weeks ago chastising me for being a "lid running a linear and wrecking the band" along with other choice phrases and showing me a screen shot of my JT9 signal at +18dB. I was running 10 milliwatts and had an IMD of -35dB. Power is only the tiniest fraction of the equation. If ops spent more time adjusting their receive settings instead of worrying about how much power someone else is running, there would be a lot more happy operators out there. Remember that the difference between 5 watts and 100 watts is only about 16 dB assuming an ideal antenna in free space. It's actually far less in real world applications. Don't misunderstand: you should only run as much power needed to make the desired contact (I seem to recall that being a question on my Technician Class License exam) and if you're calling CQ, make sure your reach does not exceed your grasp lest you become an "alligator" with more mouth than ears. 73, Jim S.
