Jim's post, reprinted in full below, is incomprehensible nonsense. Everyone but Jim knows what "current" is: The liquid-like movement of particles such as water molecules, air molecules or electrons.
At one time the entire scientific community believed the earth was flat, there were only four elements, the sun revolved around the earth and disease was caused by "vapors". Current is not an abstrac

-- ORIGINAL MESSAGE --(may be snipped) REPLY: Ever hear of Velocity Factor? It's a measure of the sped of current in a wire or pair of wires. 73, Bill W6WRT __________________________________________
-- ORIGINAL MESSAGE --(may be snipped) REPLY: Yes, but remember those diodes will get hot. I suggest the kind that can be mounted to the chassis. Also, at that current level they may produce hash in
-- ORIGINAL MESSAGE --(may be snipped) REPLY: Do the math. A pi output circuit at such low impedances uses impractical values, especially for the capacitors. 73, Bill W6WRT __________________________
-- ORIGINAL MESSAGE --(may be snipped) REPLY: I think it is true, but there is semantics involved here. Whatever "tuning" is needed is for the antenna, not the amplifier. If the antenna itself is bro

-- ORIGINAL MESSAGE --(may be snipped) REPLY: Under that definition, AM and FM are also "continuous wave". When I got into ham radio in the late '50s, the term ICW was often used, meaning "interrupte

For what it's worth: I'm OK with the 15 dB rule for one simple reason. Take the rule away and you will soon have a bunch of ten watt transceivers on the market. Ten watts on HF is pretty much useless
