Channels
Browse and search the radio channels available in the loaded codeplug.
There are two ways to look at channels, and which one you get depends on how you arrive. Coming from a zone, you see just that zone's channels in the order they sit on the radio. Coming from the Channels button on the Communications hub, you see every distinct channel name in the codeplug listed once, with a count of how many zones it appears in — expand one and you find each zone and channel position.

Overview
One zone's channels
Reached by tapping a zone in the zone list. The header is the zone's name.
| Element | What it shows |
|---|---|
| Header | The zone name |
| Row title | The channel's position in the zone, then its name |
| Row detail | The channel type in brackets, then the talkgroup number for a trunking channel or the receive frequency in MHz for a conventional one |
| Color swatch | The channel's backlight color |
| Search field | Open by default on this screen; filters as you type |
| Menu button | Opens the single option, Search, which hides or reopens the search field |
| Back | Returns to the zone list |
Every channel in the codeplug
Reached by tapping Channels on the Communications hub. Each channel name appears once, as a card.
| Element | What it shows |
|---|---|
| Channel name | In bold at the top of the card |
| Type badge | CNV in green for conventional, TRK in blue for trunking |
| Mode | The channel's mode |
| Backlight dot | A small dot in the channel's backlight color |
| Zone count | Reads in 3 zones, or in 1 zone for a single appearance |
| Chevron | Points down when collapsed, up when expanded |
| Frequency line | The receive frequency in MHz |
| Occurrence row | Appears when expanded: Zone name (Zone #3) → Ch #12 |
Backlight colors
Both lists show the channel's backlight color, which is how the channel looks on the radio's own display.
| Recognized color names | Shown as |
|---|---|
| white, black, red, green, blue, yellow | That color |
| gray, orange, purple, brown, cyan, magenta | That color |
| Anything else, or blank | No color at all |
The number in front of a channel row is its position in the zone, which is what you dial on the radio. It is not the channel's identifier, so typing that number into the search field may not find the channel — search by name instead.
Getting Here
| To see | Do this |
|---|---|
| One zone's channels | Open Zones on the Communications hub, then tap a zone |
| Every channel in the codeplug | Tap Channels on the Communications hub |
- From the Home screen, open References.
- Select Communications and choose a codeplug on Radio Info.
- Take one of the two routes above.
Searching One Zone's Channels
The search field is already open when this screen appears, so you can start typing immediately.
- Type any part of a channel name.
- The list filters as you type.
- Matching ignores capitals and matches anywhere in the text.
- Clear the field to see the full zone again.
- Tap the menu button and choose Search to hide the field; choose it again to bring it back, cleared.

Channel names in a codeplug often carry a prefix for the agency or band. Searching for a fragment from the middle of the name — a street, a district, or a talkgroup word — usually finds it faster than typing the prefix.
Searching Every Channel
The unique channel list searches on more than the name, which makes it the better place to hunt for a frequency.
| Type this | And it matches |
|---|---|
| Part of a channel name | The channel name |
cnv or trk | The channel type |
A frequency, such as 154. | The receive or transmit frequency |
| A number of zones | The zone count |
- Type in the search field at the top.
- Matching results appear as cards; expanded channels collapse back while you filter.
- Tap the menu button and choose Search to hide and clear the field.
Seeing Which Zones a Channel Is In
- On the unique channel list, tap a channel card.
- The chevron flips up and the occurrence rows fade in underneath, indented so they read as part of that channel.
- Each occurrence reads as the zone name, the zone number, and the channel position inside it — for example
4 AERO (Zone #3) → Ch #12. - Tap the card again to collapse it.
- Occurrences are remembered after the first look, so expanding the same channel again is instant.
This is the fastest way to answer "where do I find this channel on the radio?" A channel that appears in five zones shows five occurrences, each with the zone and channel position to dial.
Opening Channel Details
| From | Tap | You get |
|---|---|---|
| One zone's channel list | The channel row | That channel's full details |
| Unique channel list | An occurrence row | That specific zone's copy of the channel |
| Unique channel list | The channel card | Expand or collapse, not details |
- Tap the row.
- The Zone & Channel Details screen opens, titled with the channel name.
- Read the channel's sections there — zone and channel position, frequencies, squelch, talkgroup or system, identity, and profile.

What you see on the details screen depends on the channel type. Trunking channels show talkgroup and trunked system sections; conventional channels show frequency, squelch, and conventional system sections.
Loading, Empty, and Error States
| State | What you see |
|---|---|
| Loading | A loading indicator while the channel list is fetched or read |
| Zone with no channels | An empty list under the zone name |
| Search with no matches | An empty list until you clear the search |
| Request failed | An alert with the message returned by the server |
| Codeplug not downloaded, no connection | "This codeplug isn't available offline." |
How This Connects
- Where channels come from. Channels belong to the codeplug you opened on Radio Info. With a connection the list is fetched for that zone or codeplug as you open it; with no connection it is read from the downloaded copy on your device, so the two routes behave the same either way.
- Zones are the other way in. The per-zone list is reached from Zones, and both routes land on the same channel records described in Zone & Channel Details.
- Backlight color is radio truth. The swatch and dot are the color the channel shows on the radio display, which is how crews often refer to channels out loud — the same value appears as Backlight Color in a channel's Profile section.
- Squelch points at MPL. A channel whose squelch type is user-selectable is using the MPL positions listed in MPL Radio List, explained in MPL Configuration.
- Used with incidents. Channel assignments recorded against an incident are read in Incident Comms Tab; this screen is where you confirm what one of those channels is and where it sits on the radio. In-app talk paths are separate — see Audio Channels.
- Offline and reconnect. Both lists work offline for any codeplug that has been downloaded, including the occurrence expansion. When the connection comes back, leave the screen and reopen it so it fetches the current version.
Troubleshooting
| If this happens | What to do |
|---|---|
| Searching a channel number finds nothing | The number on the row is its position in the zone, not something the search matches. Search by name. |
| A channel row has no color swatch | The codeplug's backlight color is blank or a name the app does not recognize. |
| The same channel appears in several zones | That is normal. Use the unique channel list and expand it to see every zone and position. |
| Expanding a channel shows nothing | No occurrences could be read. Collapse it, then tap again; on a connection it fetches, offline it reads the local copy. |
| The list is empty | The zone has no channels, or a search is still filtering it. Clear the search first. |
| "This codeplug isn't available offline." | Open this codeplug once while connected so it is downloaded, then it can be read offline. |
| An alert with a server message appears | The fetch failed. Check your connection and reopen the list. |
| Trunking channels show no frequency | Trunking channels show a talkgroup number instead. The frequency belongs to the system, not the channel. |
