N0EMR/DISPATCH CONSOLE /QUINCY, IL SYSTEM ON THE AIR
Features

What the console actually does

Grouped the way you would use them, not the way the software is organised.

Monitoring and routing

Simultaneous monitoring

Every talkgroup, reflector, node and repeater you have configured is live at once. No switching modes to hear a different network.

Cross-patch

Tie two channels together so traffic on one is repeated onto the other. Bridge a local repeater to a talkgroup for an event, then take it back down.

Call log

A running record of who transmitted, on what, and when — so you can go back and check what you heard.

Recording

Capture traffic for review after an event or a net.

Custom layout

Arrange the console the way your operation works. The channels you use most go where your eye already goes.

The N0EMR call sign log: a running list of stations heard, each row showing the time, the operator's call sign and the channel or DMR talkgroup, with search, manual entry, clear and CSV export controls.
The call log — every station heard, with time, call sign and channel, searchable and exportable to CSV.
The console's digital-voice admin: D-STAR, System Fusion (YSF/FCS) and M17 networks listed, each added or removed from one screen.
Adding digital voice networks — D‑STAR, Fusion (YSF/FCS) and M17, connected or removed from one screen.

Transmitting

Per-channel PTT

Transmit on the channel you mean. The card shows key and unkey state the way a real dispatch position does.

Footswitch and pedals

Hands-free push-to-talk from a foot pedal, so your hands stay on the keyboard.

Keyboard and serial PTT

Key from a keyboard shortcut, or from a serial device if you already have dispatch hardware on the desk.

Bluetooth PTT

Pair a wireless button and key from across the room.

DTMF pad

Send tones down a channel for nodes and controllers that expect them.

The console DTMF pad: a keypad with digits, star, hash and A-D tones, a channel selector and a Send DTMF button.
The DTMF pad — send tones to nodes and controllers on any channel.

Alerting

Paging console

Two-tone paging with configurable tone and gap timing, for groups still running tone-out alerting.

Emergency

A dedicated path for emergency traffic rather than one more button in a row of buttons.

Phone patch

A phone side that lives alongside the radio side, so a call and a channel can be handled from one position.

The paging console: pager buttons and a selected page showing tone format, A and B tones, gap, and alert timing, with a Send Page button.
The paging console — two-tone, Quik-Call II and 5-tone paging, with per-pager tones and alert timing.
The N0EMR phone console: twenty telephone lines with a dial pad, hold, transfer, conference, park, radio-patch and recording controls, worked from the same position as the radios.
The phone side — twenty lines, a PSTN trunk and radio patch, worked from the same position as the radios.

Audio

Noise suppression

Clean up the transmit path so what leaves the console is intelligible on a handheld at the far end.

Per-mode levels

DMR, analog and the digital voice modes each want a different drive level. Set them independently instead of compromising.

Peripheral audio

Headset, speaker and pedal hardware handled at the operator position rather than assumed to be the computer's default sound card.

Jitter buffering

Network audio arrives unevenly. The console smooths it per channel so speech stays speech.

The console audio admin: choose the audio path (computer or peripheral hub), toggle noise suppression and voice isolation, and set per-mode TX gain.
Console audio — pick the audio path, toggle noise suppression and voice isolation, and set TX gain per mode.

Doors, gates and sensors — AUX I/O

Every gateway site can switch things and watch things, not only carry radio. Wire a door strike, a gate opener, a light or a buzzer to a spare pin on the gateway's Raspberry Pi header, wire door contacts and other switches to other pins, and each one shows up as a card in the console's AUX I/O window. You work them from the same dispatch position and the same sign-in as the radios.

When you press a button, the console sends the command to the CORE, the CORE passes it to the gateway over the link the gateway already uses, and the gateway drives the pin. A card only shows a state the gateway has actually reported. If a gateway is offline, its cards say UNKNOWN instead of guessing.

The N0EMR AUX I/O window: one gateway, online, with a red press-and-hold door output, a latching output switched on, a door contact reading CLOSED, several inputs reading NORMAL with how long they have been that way, and the gateway CPU temperature with a live graph.
The AUX I/O window — outputs to operate, inputs to watch and the gateway's own temperature, one section per gateway.
Press and hold

The output stays on only while your finger is on the button and releases as soon as you let go. If the console loses its connection during a press, the gateway releases the output by itself.

Latch

Press once for ON and again for OFF. Use it for lights and anything else that should stay the way you left it.

Timed pulse

Unlock a door strike for five seconds, or give a gate opener a one-second press. The gateway times the pulse itself, so it ends on time even if the network drops.

Confirm before it moves

Doors and gates can ask the dispatcher to confirm first, so a stray click doesn't open a gate.

Safe by default

After a restart every output starts off and nothing switches itself back on. A door can also be set to lock again on its own if its gateway loses its link.

Door contacts and inputs

Watch door and gate contacts, motion detectors, push buttons and other switches. Each card shows OPEN or CLOSED (or your own words) and how long it has been that way.

Gateway temperature

Each gateway reports its own CPU temperature, with a six-hour graph on the card and warning and alarm limits you set.

Alarms every console sees

An alarm can be raised by an input, by a temperature going past its limit, or by a gateway that stops reporting. Every console shows and sounds the same alarm. One dispatcher's acknowledgement counts for every console, and an alarm can be silenced for a set time. When the AUX I/O window is closed, the AUX I/O button on the main console flashes instead.

Sound alerts

The alarm and button sounds are built in and play on their own channel, never mixed into radio audio. Each sign-in has its own volume and mute.

Sensor history

Look back over the last hour, 24 hours, 7 days or 30 days of any temperature reading, with the limits, gaps and alarms marked, and export it to CSV.

Your names, icons and colours

Name every pin, choose its type (door, gate, light, buzzer or a type of your own, with its own icon and colour) and choose the words its states show.

Your layout

Each dispatcher can drag the cards into the order and groups that suit them and hide the ones they don't use. The layout follows their sign-in to any console.

Who did what, and when

Every press, release, change, alarm and acknowledgement is logged with who did it, when and from where. The log is kept for a year and exports to CSV, and each card shows who operated it last.

Who can operate

Any signed-in dispatcher can operate the pins. Only an administrator can add, rename or rewire them.

Every gateway, its own pins

Each gateway gets its own section in the window, with up to 24 of its Raspberry Pi header pins available for inputs and outputs.

Two AUX I/O output cards: a door output in press-and-hold mode whose button reads Press and hold, releases when you let go, and a latching output switched on, each showing who operated it last.
Outputs — press-and-hold and latch, with who operated them last.
Two AUX I/O input cards: a front door contact reading CLOSED and a gate input reading NORMAL, each showing how long it has been in that state.
Inputs — a door contact and a gate, and how long each has been that way.
The gateway CPU temperature card: 127.5 degrees Fahrenheit, a steady trend arrow, a live graph and a NORMAL status.
Gateway temperature — the live reading, its graph and its status.

Running it

Multiple operators

More than one dispatch position, each signed in, each able to see that the others are there.

Gateway health

See which sites are up, which are unreachable, and which radio is transmitting right now.

Hub failover

A second hub can stand behind the first, so a single machine isn't the whole system.

Diagnostics and logs

When something sounds wrong, the console can tell you where in the chain it went wrong.

Hub administration — server health, running services and every gateway and channel, from the browser.
