Frequently Asked Questions
Is Portland Police Bureau radio encrypted?
Yes — Portland Police Bureau's radio system runs on P25 AES-256 encryption. All traffic, including the day-to-day dispatch that used to be the public's window into police activity, now runs encrypted. Nothing from this department is receivable.
Can I listen to Portland Police Bureau on a police scanner?
No. Portland Police Bureau has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Portland Police Bureau encrypt their radio?
Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Multnomah County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.
Can Multnomah County reverse the encryption decision?
Yes. Whoever made this call for Portland Police Bureau can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.
What can I do about Portland Police Bureau encryption?
Contact the officials who oversee Portland Police Bureau's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Multnomah County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
