How is over the air access to Internet Radio Linking Project (IRLP) nodes accomplished?
By obtaining a password that is sent via voice to the node
By using Dual-Tone Multi-Frequency (DTMF) signals✓Ճիշտ պատասխան
By entering the proper internet password
By using Continuous Tone-Coded Squelch System (CTCSS) tone codes
Բացատրություն
IRLP node connections are commanded over the air by sending DTMF digits from your radio's keypad, which the node decodes as node numbers and control codes. CTCSS tones only open squelch and carry no digits, and internet passwords are not sent over a voice radio link.
