First, I'm not a doctor nor do I play one on TV, but because of an experience I had, I urge that before you commit to a pacemaker procedure, make a careful review of ALL the drugs you are taking for

I'm pretty much a lurker here, and I find the discussions to be interesting and educational. Yes even the arguments provide some education and a little entertainment. As to what constitutes "real" ha

I'm reminded of a proverb (Chinese?) which I may be slightly misquoting: "The man who has but one watch always knows what time it is, while the man who has two is never sure." Since my amp will almos

Author: <chris@chrishays.com>

Another reason I suspect is the C-L-C pi network allows both the variable capacitor rotors to be at ground potential. This lets the shaft be at ground potential making for a safer control that is not

Well, if the shunt were open you would see a pinned meter and it would possibly burn it out (which would leave you with a dead amp). The switch is the most likely of what you have mentioned, but with

Just to make sure there is no confusion, a properly operating AM transmitter will double voltage and current (peak) at its output at 100% modulation regardless of the technology used to make the AM.

Humor aside, one thing that phone transmitters require is power. The fact that you can copy a CW signal at a far lower signal level than a phone signal means that lower power can be effective. There
