For callsign look-up each letter or number is represented by a two-digit code. The first digit is the number key and the second digit denotes which letter. So, 2=20 A=21 B=22 C=23 etc. For example, to connect to AE6NX (if you don't know the node number): C 21 32 60 62 92 # Tip: The first match that is found will be selected, so you don't need to key in the -L or -R
