N6JET DigiScope — User Guide

Launch DigiScope: http://5.161.215.224:8091/

Five tabs at the bottom of every page let you navigate between sections: SCAN, LAST HEARD, BANKS, CHANNELS, and OPTIONS.

The Scanner Page

This is the main display — it works like a digital voice scanner.

The Display

The large green text in the center shows the name of the channel currently being scanned. Above it you'll see the bank name, channel number, and the current status:

SCANNING (blinking) — stepping through channels looking for activity
ACTIVE — stopped on a channel with live traffic
PRIORITY — priority channel activity detected
HOLD — scanner is paused on the current channel

Below the channel name, three fields show the mode (DMR, YSF, etc.), the network name, and the callsign of the last station heard.

Signal Meter

The bar graph labeled S shows how much activity is on the current channel. More bars means more recent transmissions.

Status Flags

PRI — lights red when the current channel is the priority channel
L/O — lights green when the current channel is locked out
DLY — shows the current delay setting
HOLD — lights green when the scanner is held
AUDIO — lights green when audio is enabled (future feature)

Bank Buttons

The row labeled BANKS shows your ten bank slots (0-9). Programmed banks appear lit in green with their name. Click a bank button to toggle it on or off — when off, its channels are skipped during scanning.

Function Buttons

Button	What It Does
SCAN	Start scanning through all enabled bank channels automatically
MANUAL	Step through channels one at a time — click repeatedly to advance
HOLD	Freeze on the current channel — click again to resume
L/O	Lock out the current channel (skip it) — click again to unlock
DELAY	Cycle through delay options: 0s, 1s, 2s, 5s
PRI	Toggle priority scanning on/off

Ticker

The scrolling bar at the bottom shows recent transmissions — callsign, network, and time.

Night Mode

Click NIGHT in the top right corner for a red-on-black display. Click DAY to switch back.

The Last Heard Page

LED Grid

Channels are grouped by mode (DMR, P25, XLX, M17, YSF, etc.). Each channel has a small LED indicator:

Green LED (pulsing) — recent activity on that channel
Dark LED — no recent activity

Active channels show the callsign and timestamp of the last transmission.

Activity Table

A scrolling table showing every recent transmission:

Column	Shows
Time (UTC)	When the transmission was heard
Network	Which reflector or talkgroup (color-coded by mode)
Callsign	Who was transmitting
Target	The destination (module, talkgroup, etc.)
Via	The repeater or hotspot used
Dur	Duration of the transmission

The Channels Page

This is where you program what DigiScope monitors.

Adding a Channel

Three ways to add a channel:

Pick from Database — click to see sources the system has detected. Click one to auto-fill the form, then click + ADD CHANNEL.
Manual Entry — fill in Source ID, Display Label, Sublabel, and Mode, then click + ADD CHANNEL.
Import CSV — load channels from a CSV file (see format below).

Exporting Channels

Click EXPORT CSV to download your current channel list as a backup.

Managing Channels

AUD — click to toggle audio on/off (future feature)
PRI — on Channel 01 only, click to toggle priority
▲ ▼ — move the channel up or down
✕ — remove the channel

Click SAVE CHANGES after making modifications.
