For the Uniden UBC125XLT & BC125AT · macOS
Program your scanner from your Mac. Then just listen.
Sweep 125 is a scanner updater with live data. It reads and writes every channel over USB, keeps a library of 8,000+ airports and places, and shows live aircraft, ships and airport weather around you.
The app mirrors the radio's own display, so you always know what you're hearing.
Tell it where you are in plain words. It loads the right frequencies into a bank and starts scanning.

What it does
Programming takes minutes, not weeks
READ · WRITE
The whole scanner over USB
Pull every bank off the radio, change what you like, and write back only what changed.
LOCATIONS
An unlimited library
Save as many places as you want. Use the radio's 10 banks, plus 20 reserve banks on your Mac ready to swap in.
MAP
What's near you
Search anywhere or use your location, set a radius, and add nearby airports and services in one click.
LIVE DATA
Aircraft, ships and weather
Live aircraft and ship positions, airport weather and aircraft photos from public data services, shown on the map.
RADIO SETTINGS
Close Call and searches
Pick Close Call bands, service searches and custom ranges on screen, then write them to the radio.
BACKUPS
Undo for your scanner
Back up every channel and setting before changes. Restore the whole radio, one bank, or just the channels you pick.
SAFE WRITES
Know when it's safe to unplug
Every channel is read back after writing. If the cable comes out mid-write, Sweep 125 picks up where it left off.
LISTENING MODE
Read it across the room
A big display of what's on, with signal strength, bank buttons and Scan / Hold / Lock out.
ACTIVITY
See what's busy
A live activity monitor: busiest channels, airtime and last heard, over 5 minutes to 7 days, plus a timestamped log. Export as a spreadsheet.
LIVE ATC TO TEXT
See who's being called
Turns calls into text on your Mac and highlights the plane being called. Nothing is recorded or sent anywhere. Off by default; only use it where the law allows.
IMPORT · EXPORT
Bring your channels with you
Import and export CSV spreadsheets and Uniden .bc125at_ss files.
HELP BUILT IN
