"What were some other names for the device that RCA called a tone decoder?" CTCSS is often called PL tone (for Private Line, a trademark of Motorola to describe their implementation of Continuous Tone Coded Squelch System). Best regards, Richaard Harrison, KB5WZI |

HF Diversity reception ?
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 Hank "Dave" wrote in message ...

Best regards, Richaard Harrison, KB5WZI 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. |

"Continuous Tone Coded Subaudible Squelch" I like that better than "Continuous Tone Coded Squelch System" as "System" is nondescriptive. Best regards, Richard Harrison, KB5WZI |

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