A developer has enabled the Flipper Zero to transmit APRS (Automatic Packet Reporting System) signals without any external hardware. By leveraging the Flipper's built-in 435 MHz radio and creatively using its FSK modulation to approximate FM, the device can function as a standalone APRS station. The approach has some compatibility limitations since FSK-as-FM won't be decoded by all receivers, but it requires no additional parts beyond the Flipper itself.
