Training/explanation on PL tones

[needairtime]

At least Kleenex hints at how it's used! (Can't say the same for Q-tips...)

 

[dlwtrunked]

The term "PL" is a proprietary Motorola name for CTCSS that has come into common usage to the point of becoming a generic term. It's just like Kleenex becoming generic for tissue and Q-Tip becoming generic for cotton swab.

Indeed, and saying " CTCSS" or "Continuous Tone Coded Squelch", though a more accurate description, is far too long and will not help and even more confuse the confused. I think "Tone squelch" alone would be reasonable but prefer "PL tone".

Yes, we need to stop calling them PL tones. PL isn't even private, and it only makes things more confusing. The better name, CTCSS, Continuous Tone Coded Squelch System even helps people understand it. I suppose people should know what squelch is as a base line... then the continuous tone that activates squelch, that makes a lot more sense at least to me!

Get used to it. Handie Talkie was a trade name. I think Walkie Talkie was, too. That's why most people call them portables. Band-Aid, Aspirin, Escalator, Thermos, Dry Ice, Zipper, TV Dinner, Cellophane, Coke, Plexiglass and many others are or were registered.
