The Contacts feature of the iPhone is a fairly handy little database, that you can use a simple Search function to track people on your Contact List, who have for example a callsign.
When you enter a persons details in eg name and phone number, scroll down to the bottom to the section called Notes. If you then enter their call sign in, while searching you can pull up their contact details.
In fact, as you type in VK3 it brings up a list of all contacts that have VK3 in their card.
If I'm entering club members I also put FAMPARC in the notes, so again I can search on that phrase.
I have been putting the callsign into the Company section and when searching VK3 it brings up all of them too. Perhaps I can compare my entries with your method Phillip?
