P25

Project 25 (P25) is a digital voice standard developed for public safety and professional radio use. A growing number of amateur radios and commercial/surplus radios re-purposed for ham use support P25 Phase I, and WPSD can bridge your hotspot onto the amateur P25 reflector network.

To begin, in the MMDVMHost Modem Configuration section, toggle P25 mode on. Apply Changes to save the configuration. After the hotspot re-starts and the page returns, scroll to the P25 Configuration section.

Set a P25 Hosts startup host. This is the P25 reflector (identified by a numeric ID, not a friendly name) that WPSD will connect to automatically when the hotspot starts. You may also choose none to start unlinked, or 10 - Parrot to test your setup by talking to yourself.

Tip

Unlike DMR talkgroups or YSF rooms, P25 reflectors are referenced purely by number — there is no descriptive name shown next to most entries in the list. If you’re not sure which number you want, check the reflector list on your favorite P25 reference site before you start, or just begin with Parrot to confirm your radio and hotspot are talking to each other.

If your radio or local convention requires a specific Network Access Code (NAC), a P25 NAC field will appear once one is set in your configuration; otherwise you can leave this alone.

If you have followed the instructions correctly, on your Dashboard in Mode Status, you should see P25 green, and in Network Status, you should see P25 Net green.

You have completed configuring your hotspot for P25 mode.

Linking and unlinking reflectors

Once P25 mode is running, you don’t need to re-enter the Configuration page every time you want to change reflectors. Use the P25 Manager page (Admin -> P25 Manager) to pick a reflector from the dropdown and Link or Unlink on demand — this is a temporary link that reverts to your configured startup host the next time the hotspot restarts (such as during nightly maintenance).

Note

The P25 Manager page requires P25Gateway’s Remote Commands to be enabled, which is on by default in a stock WPSD installation. If the P25 Manager menu item is greyed out with a “Mode is Disabled” tooltip, go back and confirm P25 mode is toggled on in the Configuration page.
