![]() That got me thinking about many other ways the ESP32 could be used as a packet radio interface, not only as an audio relay but also as a full-blown packet modem, an audio signal analyzer, and an APRS modem or gateway.įor this project, I will interface to an Icom ID-5100a and a Boafeng UV-5R, since that's what I have, but the modem will be easily reconfigurable for virtually any HF or VHF/UHF radio, with some manual cable or headset hacking. Unable to participate without a digital interface for my radios, I dug through my parts bin and had the idea of using an ESP32 as a Bluetooth audio relay. After I joined the local ARES chapter in March, I tuned in to an over-the-air activity day, learned about this group's use of Winlink for coordination between EMCOMM stations, and observed an exercise simulating an emergency scenario. I am a new ham, with a mobile radio, a couple of HTs, a modest budget, and an interest in supporting emergency communications. It will be functionally similar to a combination of a wireless version of the Signalink USB soundcard ($140) and a Mobilinkd TNC3 ($120), for a small fraction of the price of each of these commercial units individually. The device provides two operating modes: 1) audio relay services for use with modem software on the controlling PC, and 2) as a packet radio modem. ![]() ![]() This ESP32-based device attaches to the mic/audio-in and speaker/audio-out jacks of virtually any ham radio and connects to a controlling PC via USB, Wifi, or Bluetooth. This project aims to develop a dirt-cheap, open-source, highly reconfigurable, wireless PC-radio interface to support various packet radio modes. ![]()
