Hey everyone, hope you're having a great night.

I dug out my old radio scanner, and I know the police have gone ahead and crypted their digital network, but I would still like to listen to marine, fire, or ambo's, but all the New Zealand sites greet me with 7 digit codes. My Uniden UBC72XLT only has the option to add a 6 digit frequency.

What do I do?

Thanks!
