I am learning about DTMF. My question is, can DTMF be employed to squelch all traffic on a repeater unless the DTMF tone is heard?
For example, say a rig is set to a local repeater frequency, but I only want to hear from my friend "Carl". Can the rig be set to only only the squelch if the specified DTMF tone is transmitted?
