Part of the problem, I think, is that people have simply forgotten how to monitor their own signal, or never bothered to learn how. It doesn’t matter if you’re using the latest DSP wizbang SSB radio or a Central Electronics 10A to transmit. Listening to yourself on an IF level “audio” monitor, won’t tell you if you’re overdriving and flat topping in the amp. Not likely that a P3 monitor function — if it only displays signals from the K3 DSP — will help much in that regard either. Compression and processing don’t necessarily cause a wide signal — but of course since the knob is there, if a little bit is good, then a whole lot MUST BE better .. or at least that’s clearly the view of many.
Every station needs a scope, and the only way to guarantee a clean signal (even if the K3 or radio du jour is generating a perfectly clean one in it’s DSP) is to use it properly to evaluate the RF going into the antenna, after the very last stage of that extra special 10KW contest amp … Grant NQ5T On Apr 10, 2014, at 12:09 AM, Jim Brown <j...@audiosystemsgroup.com> wrote: > On 4/9/2014 6:56 PM, Milverton M.
