CTCSS is often called PL tone (for Private Line, a trademark of Motorola
to describe their implementation of Continuous Tone Coded Squelch
System).

Continuous Tone Coded Subaudible Squelch

Hey Guys
I made an error when I called the RCA device that selects the best Rx a
Tone Decoder, it's called a Tone Keyer. It selects the strongest of 3
HF Rx signals and amplifies it. What did the other HF diversity makers
call Tone Keyer.
I know about CTCSS but its unrelated to my query.
Thanks
Hank

Continuous Tone Coded Subaudible Squelch

I had a "Westinghouse" dual version of the Racal RA-117 with 2 RF
chains. There was a "voter" of some kind that went with it, but I did
not have that part.

I like that better than "Continuous Tone Coded Squelch System" as
"System" is nondescriptive.

I think it's from the MOCOM 70 Service Manual. Motorola called it
"Private Line".

Thanks Dave, I was trying to remember "PL tones".

Since it appears that you do not want a telephone DTMF decoder what is
it that you want to decode?

No decoding involved. It's a tone that unsquelches an FM radio.

Which make and model / series? There are dozens of variations.
