Sorting Radio Call Signs
I am a amateur radio operator. I created a database of all the other operators I have had conversations with. The call signs have one number preceded and followed by one or more letters. Examples: KA8VAL, K2AN, N7CGE, KB6TQ, KA8NXV. I would like to sort first by the number, which indicates the region of the station and finally by the letters following the number. In the examples above, the sorting would be: K2AN, KB6TQ, N7CGE, KA8NXV, KA8VAL. If a script is the way to go, please give me the code. I am using FM-11 with a MAC running OS 10.5.8. Thanks for your assistance.
