Verification Status

We don't yet have per-talkgroup data for Gresham Police Department from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at moderate confidence (70%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Gresham Police Department directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Why do agencies like Gresham Police Department encrypt their radio?

Can Multnomah County reverse the encryption decision?

Yes — nothing about the underlying radio technology forces this. It's a decision Multnomah County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.

What can I do about Gresham Police Department encryption?
