For Radars:

- Take the first letter and first digit in the serial number. Modulo 5 until they are between A-E and 1-5. This is your first location.
- Repeat for the second and third letters and digits until you run out of either of them. These are your second and third locations.
- Take the number of ports, then add or subtract 5 until it is between A-E. Add the number of indicators and batteries together, then add or subtract 5 until it is between 1-5. This is your final location.
