What are CTCSS, CTC, PL, DTC, DCS, DPL Tones on GMRS and Ham Radio - Squelch Tones Explained

In this educational video I explain what ham radio, GMRS radio and FRS walkie-talkie "tones" are - CTCSS, CTC, DPL, DTC, DCS, PL, sub-channels and privacy codes - for both walkie-talkie hand held radios, scanners and repeaters. I explain all of these radio tones and codes in a way that even you will probably understand. These radio squelch tones are available features on all ham radios, GMRS radios, most FRS type walkie talkies, police scanners, and they are even required to use most ham repeaters and GMRS repeaters, so you understanding what they do is probably a good idea.
