Thanks to Dave WE1U, for compiling these notes.
REMEMBER the codes work only on the repeater to link/unlink and NOT through the link.
The repeater IDs are 67, 88, 85, 82, 97, 35, etc.
1=listen to link only 2=connect to the link 3=to end the link
For example, to put Buckfied 146.880 (- / 100Hz) into the link system, the tones are 882.
You must be on the 88.
Press the PTT
Say "This is <callsign> sending tones <keypad 882> <callsign>"
Release the PTT
You should hear the repeater state "Transmit"
To unlink 88:
You must be on the 88.
Check to see if anyone need to use the 88 linked if you can.
Press the PTT
Say "This is <callsign> sending tones <keypad 883> <callsign>"
Release the PTT
You should hear the repeater state "OFF"
