The rule of thumb in the world of professional audio is that you should -cut- rather than boost frequencies to achieve the sound you want when using "equalizers". So, if you have a lot of highs... cut the highs. Adjust overall gain upward to compensate if the overall level becomes too low.
From what I understand, "ESSB" is simply wider bandwidth sideband... usually by using a wider filter to permit more low audio frequencies and more high audio frequencies to pass through. The result is an on- air signal that "sounds nicer"... since with it's wider bandwidth, approaches the audio sound of an AM station that has no bandwidth filtering or constriction. You can argue the case that ESSB is not good amateur practice, since you are using more bandwidth for your communication, but then, the good practice (and FCC rule) of using only the minimum power necessary to maintain communication is honored more in the breech, than the observance. But, there are many hams, and many ways of communicating and as long as the RF emissions are clean and in line with FCC regulations, there's room for all types of signals and bandwidths. Certainly, ESSB is no wider than an AM signal can be, and AM is clearly permitted in the rules. 73 de Ray K2ULR On Jun 19, 2012, at 8:18 AM, ac8jd wrote: > I have had this K3 up on the air for a few days now.
