What are use-cases for DTMF & ANI sidetones in GMRS? (and related menus on KG-935G)
HI folks,

None of the GMRS repeaters I have encountered require any DTMF or "tone burst". So what is the use-case for DTMF and ANI in the GMRS context? I've set ANI to transmit a code (305), and I hear it being sent. But why (aside from a "custom" roger beep

It is a feature that can be used when you have a special need for it. - DTMF codes are commonly used to remotely control repeaters and to control other electronics that might be monitoring the frequency. - In some radio circles (outside GMRS) some repeaters and other radios might require b
