Also I've noticed CSQ listed in the tone on somq frequencies.
What does that mean?
I've read the Wiki and I think I understand but I wasn't sure so before I enter a ton of mistakes I wanted to check with the experts.
CSQ = Carrier squelch
CTCSS = Continuous Tone-Coded Squelch System
CTCSS brand names: Private-Line (PL), Channel Guard (CG), Quiet Tone (QT)
DPL = Motorola Digital Private Line (DPL). Motorola trademarked the DPL name, so other radio manufacturers have to call it something different. Digital Coded Squelch (DCS) appears to be the generic name. Although DCS and DPL are the same thing, if it's not a Motorola radio you're referring to, it's not DPL. Kenwood calls it Digital Quiet Tone (DQT) in their radios. ICOM calls it Digital Tone-Coded Squelch (DTCS).
