Re: REPLACEMENT FOR MM5369 TIMEBASE CHIP

I noticed this thread a little late, but I wanted to comment on chip operation. Looking back at my two-way-radio reapir days in LA, Motorola-designed frequency-generation chips (an entire series of divide-by-n and integrated PLL chips) that were desined to work together in a multi-step scheme. The g...

Re: Do orbiting wires generate?

Some years ago NASA did an experiment where they slowly SPUN a long conductor loop behind the shuttle, thus negating the nifty trig/magnetic math formulas posted peviously. It oh-so-briefly generated a rather large amount of current, dissipated through a dummy load, before the cable broke.<p>I'm sti...

Re: Boosting AM - Still Done The Same Old Way?

IIRC, a Nat'l Radio Club review of the then-new GE SupeRadio II mentioned that a Select-A-tenna did very little for the radio. It went into further detail in that the SAT worked best (and quite well) with radios having poor front ends. The SAT worked equally poorly with other high-quality radios.
