How It Works

1
🔍 Discover the radio messenger

You hear about a fun app that lets your Flipper Zero send short radio messages to other radios, like position updates or hellos.

2
💾 Get and add the app

Download the ready-to-use file from the project page and copy it to your Flipper Zero's memory card to install it easily.

3
📱 Open and explore

Launch the app on your Flipper, browse the simple menus to see sample messages, spots on a map, or quick status notes.

4
✏️ Personalize your notes

Add your own radio nickname, craft a message or location spot, and save a few favorites for quick use.

5
📡 Tune and transmit

Pick a clear radio channel, tweak a couple settings if needed, then hit send to beam your message into the air with exciting repeats.

✅ Message received

What is flipper-zero-aprs-tx?

This C app turns a Flipper Zero into a pocket-sized APRS transmitter using its Sub-GHz module exclusively—no audio cables or extra hardware needed. It sends APRS messages, status packets, bulletins, and fixed-position beacons on ISM or ham frequencies like 433 MHz, with tunable deviation and modulation for better decoding on receivers like Direwolf or UV-878 handhelds. Perfect for a cheap, DIY APRS transmitter when you're out testing APRS radio without lugging an Arduino or Raspberry Pi setup.

Why is it gaining traction?

Unlike audio APRS hacks or bulkier ESP32 APRS GitHub projects, this leverages Flipper's native Sub-GHz for a mini APRS transmitter that's truly portable and standalone. Developers dig the callbook, path options (WIDE1-1, NOGATE), and repeat TX features, plus debug modes to tweak for flaky decodes—ideal for github aprs tracker experiments without Lora or igate complexity.

Who should use this?

Ham operators building a 2m APRS transmitter or aprs beacon transmitter for field tests, or Flipper tinkerers wanting an aprs transmitter module for beacons and positions. Great for portable tracking on hikes, not fixed igates or high-reliability needs.

Verdict

Grab it if you're into experimental APRS on Flipper—solid for play, with prebuilt .fap releases and clear docs. At 19 stars and 0.7% credibility score, it's raw and decode-dependent, so test indoors won't cut it; elevate for range. (198 words)
