Gene's note about the PTT/Key line question, and the current discussion of DC voltage vs amplifier output power, raise a question I have been mulling for a while. An enormous amount of information develops on this reflector over time - some of it due to F/W changes, as the PTT issue has, and some of it just adds to what’s available in the current manuals and texts as odd problems and questions come up and get debated and answered.
I personally find searching the reflector archives clunky at best, even using the Google-first method, though that’s better than word-searching the archives themselves. Would there be any value to having an updatable collection of some sort, kind of like the old QST “Hints & Kinks”, gathering up the info developed here but organized in some topically accessible way? I have been considering this as a post-retirement project, but don’t want to do it if what’s already available works well enough. And while I am not an EE or anything like it, I have had a conversation about partnering with a familiar name who is (but who is still thinking about it and so remains unnamed. Having him in on the project is a sine qua non for me.) If we do it I would want it to be “crowd sourced” in the sense that suggestions for topics and a way of selecting among replies would come from the users, on some other facility so we don’t tie up the reflector’s bandwidth. No commitment here to do it, yet; and life has a way of interfering with even the best laid plans. But I thought I’d ask if there would be any value in our thinking about it more seriously . . . or would it be superfluous?
