WS-1040 NAC ????

How do I find this NAC (490)

Do you mean NAC? NAS doesn't apply to a scanner. What are you trying to do?

You're a premium subscriber so you should have access to frequency data search. Enter the frequency (which you neglected to provide) and the NAC in their respective text boxes as illustrated below and see if any results come up.

I am trying to listen to 155.550 Polk County, WI Sherrif sorry for posting the wrong letters

Op is most like referencing this, which fwiw, does show partial encryption.

If I put in 155.550 all I hear is a buzzing sound The letter e does that mean the freq is encyrpted?

As mentioned above, it's noted that encryption is used on this channel.

You have to program it as a P25 frequency. It sounds like you have it programmed as analog

It's listed in the RRDB as partially-encrypted (P25e, lowercase "e" suffix) meaning you should be able to hear some clear transmissions assuming they haven't since switched to full encryption. As previously mentioned you'll need to program sq mode as P25 & program NAC as described here

Usually when one hears the buzzing, it means the freq is programmed into the scanner as analog. Are you entering it as P25?

The letter e does that mean the freq is encyrpted?

Like others have said, yes, but partially meaning maybe just dispatch is E, or just units are E. At some point, encryption was observed and submitted to our database. If that stands true today, and it's still only partial, you should hear something if programmed correctly.

Encryption sounds like distorted audio which you cannot understand. If you hear a buzzing sound, you most likely have it programmed as analog. The same frequency is used for both analog and digital. If you don't have the PL tone programmed for the analog frequency, you will also receive the digital signal and hear the buzz.
