Handheld T Display P4 & ESP32-P4 SDR scanners - RTL-SDR or LR2021 SDR, P25 Phase 1, FM/AM, ADS-B and POCSAG, plus onboard LoRa/MeshCore, GPS and Flipper .sub capture. No PC.

Python Script to process input data from rtl_fm and multimon-NG - multiple Plugin support

Universal POCSAG transmitter controller written in Rust.

Raspberry Pi POCSAG Decoder (it can also be used to decode a variety of other digital transmissions.) Supports RTL-SDR devices.

A Textual TUI for multimon-ng — decode POCSAG and FLEX pager messages from SDR applications in your terminal or web browser.

Make your old POCSAG pager great again :-)

A professional ESP32-based DMR hotspot with MMDVM modem support, real-time web interface and BrandMeister network integration.

Wireshark for the radio spectrum: channelize a wide span once, decode every signal in it at once

POCSAG parser implemented in Go

Mayhem for Android with custom Kotlin drivers

Pocket spectrum analyzer + multimode radio + signal decoder on a Raspberry Pi Zero 2 W and RTL-SDR, used from your phone's browser. Sweep 0.5–1766 MHz, tap a signal to hear it, identify digital modes, decode pagers, APRS, sensors and ADS-B, record, scan and watch 24/7. Offline, receive-only, EN/ES.

SDR decoder for POCSAG and ACARS messages

Send local Message over Websocket

Digital radio transmission decoder

Decode pocsag number in 1200bps from NFM 32KHz sample rate wav recording. 2 bits error can be corrected by BCH(31,21).

An ESP32-C3 replaces the radio module in a Motorola Advisor or similar pager. The ESP32 bit-bangs either GSC or POCSAG encoded pages into the pager's data_in pin so the original hardware actually receives/displays the page for an authentic retro experience. Web UI and API via WiFi and easy integration into an Asterisk PBX with included dial plan.
