Correct.? They use trial and error.? They have no clue how much? RF current is flowing through any component.? ? They just.....'pile drive'? the crap out of anything and everything...then wonder why the tube doesn't last.? Ditto with parts.? They overheat and blow up, or peak V? arcs something.? ?The last goofy one I saw on De luna's? fb page.... was where a fellow used magnet wire for the coil on the tuned input, fine..... but he had a mile long magnet wire...going to the cathode of the gg triode.?
Mike,? good detailed description.? ? Problem is..... typ 11m op wouldn't have a clue how to plate modulate anything.?
Why mess with AM is beyond me....esp when using a linear amp? in AM mode.? ?As I have shown before,? SSB has a 12.04 db? advantage over AM.?
EG:? ?CXR? is? 6 kw........swings to 9 kw.? Pep out is 24 kw.? ?When it swings from 6 - 9 kw, that's? 3 kw of total sideband power...with just 1.5 kw into each sideband.? ?You could get 1.5 kw into one sideband with a 8877.
Same tube, with 24 kw pep out on ssb.? ?24 kw / 1.5 kw =? 12.04 db.? ?This is why linear AM? is? such a wasted effort.?
IF I was a hardcore? 11 m op....... I would put up? 2-3-4? stacked yagi's....and clean house.? ?Then worry abt the amp.....and also deep six? AM mode.??
