[QUOTE="kd5rjz, post: 1753079, member: 2115"] CTCSS or what is commonly referred to as "PL Tones" are part a squelching system. It's simply a subaudible tone sent along with your audio that can disable squelch on radios programmed to squelch by CTCSS. For instance, some repeaters won't key up if the audio they receive isn't accompanied by a specific PL tone. However, anyone monitoring can still hear your conversation. It's a way to filter out other people's transmissions, not code your own.

Ham Radio is no longer a hobby for the technically minded, it's a hobby where ARRL PR guys use technically minded people's accomplishments to get publicity and donations. [/QUOTE]
