1. Independent of any issues with my particular power output empirical experience with my 2 identical radio models, my question remains: Does anyone know what the Motorola spec is for verifying output power in terms of A) cable length from transceiver to load, and B) cable type? I'd like to keep this as an independent issue from any other aspect of my findings. A very simple question, looking for a simple, factual answer. Thanks, in advance, too!
2. If you are familiar with ISO-9000 manufacturing standards, ceteris paribus, any 2 Motorola radios of the same model type shipped (even a year apart) should be within a tighter tolerance than 2+ watts, given both are set at 53 watts max, etc. ISO-9000 essentially calls for almost six sigma for manufacturing (and, Yes, I know that the famous six sigma vs/ ISO-9000 debate rages on!).
I sat through a Motorola ISO-9000 and Six Sigma Quality Process lecture recently. They bragged that even a crooked escutcheon (Motorola nameplate) on one of their two-way radios (and I won't even bore you with his engineering explanation of the definition of how much tolerance dictates a nameplate to be defective vs/ Pass), is an error under ISO-9000. And, such a seemingly innocuous error with a frikin' nameplate causes that unit to Fail, no different than if it had Zero power output! It is a defective unit, and is summarily rejected, just the same! Motorola accepts no more than 3 to 4 defects per million units under six sigma standards.
The Motorola EE giving this talk went into great detail reminiscing about how a "hot Micor receiver coming off the line, with a particularly hot front end, etc." was duly noted back in the early 1970's. By contrast to Motorola's modern day, ISO-9000 Quality Standards, he said that APX7000 mobiles come down the line essentially with identical performance tests, regardless if you pull any given radio at random for testing.
Therefore, having 2 radios apart by nearly 3 watts out of 50 is probably not meeting six sigma, albeit as a EE I'll be the first to admit, I don't know this for a fact, but I would be surprised to find that it is acceptable under ISO-9000 standards to have one radio test out at 52.9 watts, and another identical model test out at 50.1 watts. That would be fine in 1972 for 2 Micors, but I suspect (and, as Bill O’Reilly would say, “I could definitely be wrong”) this is not acceptable under ISO-9000 standards today.
Needless to say, I don't plan to send my radio in for warranty attention, but it is an interesting situation to me. Sorry, just spinning some curiosity wheels in my polluted engineering mind.
