I found this in another forum:
DPL = Digital Private Line. It's like PL tones, but it's a digital code that is sent instead of the sub-audible tone. It's just another option. 071 is the digital code that is used. It doesn't mean the audio signal is digital, just that the squelch code is a digital code that is sent out."
So, I understand what PL and DPL tones are, I'm just curious if the UV5R or the UV17 Pro are capable of transmitting the DPL codes?
" (2) If it says, for example, 071 DPL what does that mean? Is this simply just digital? What is the number 071?
