[chirp_users] UV-82 "Privacy coding (tones)"

[Dennis Smith]

Jim, I'm sure you will agree with me that the marketing department in
Motorola (who (if I'm not mistaken) first called them "Privacy Tones")
must have known that they were blatantly misleading people, where as
most other companies call them by the anachronism CTCSS correctly.
This explains CTCSS for the lay-user quite well.

The purpose of tones is not to create privacy, but to allow a radio to ignore transmissions that are not meant for it. When you set a receive tone the radio will remain silent unless a transmitting radio sends that tone. With no tone set a receiving radio will receive all transmissions on its set frequency regardless of whatever tones may be transmitted.

No matter what combination I tried, my BF8-HP (listening to the same frequency but no codes programmed) picked up every transmission. Also, the UV-82 would receive anything I sent with the BF8. The most I could accomplish was the the UV-82 would receive only the carrier and wouldn’t produce any of the audio. Downloading the daily build changed nothing and I even copied the settings from a working repeater channel and just removed the offset and still nothing. Is there a bug? Am I an idiot? I was able to program all my repeaters just fine and the tones are obviously working or the repeaters wouldn’t! Does the software ignore tone settings if there is no repeater offsets? Im doubtful as the LCD displayed the changes? Surely someone besides me wants some simplex “privacy”?
