Hamradio HF digital teletype modem for PocketPC.

This project explores embedded RF development using Arduino on ESP32 LoRa hardware, implementing a CW Fox Hunt Beacon and a separate project for a dedicated receiver. The beacon transmits a user configurable, identification string, in Morse code at 12 WPM, followed by a 10-second carrier and 20-second pause cycle. It operates at ~10 mW, offering several hours of runtime on an 800 mAh battery. The firmware allows full parameterisation in code, including operating frequency, CW speed, transmit message, carrier duration, pause interval, and RF output power adjustable from -9 dBm to +21 dBm (0.12 mW–125 mW). A programmable button enables TX disable and deep sleep mode. The receiver project is published on its own project page: https://lora-ham-fox-hunt-receive-70cm.sourceforge.io CODE FOR THIS PROJECT HAS NOW BEEN RELEASED. Download the Arduino Sketch from the Files section.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.

For content encryption, the use of Java's facilities is being considered as a long term option.

Simple Lossless Ad-hoc Protocol (SLAP) is designed to be used for wireless digital data transfer on embedded systems. The program is built for uClinux, a derivative of Linux designed for embedded microcontrollers, but can be easily ported.
