Amateur Radio Digital Modes: Guides and Resources
Find guides, software reviews, and operating tips for various digital communication methods used by ham radio operators.
Digital modes allow ham radio operators to exchange information beyond traditional voice or Morse code. These modes convert data into audio signals that a transceiver can transmit, enabling reliable QSOs even with weak signals or challenging propagation. From text messaging to image transmission, digital modes open up many new ways to operate on the HF, VHF, and UHF bands.
Hams can find detailed descriptions and sound samples for popular digital modes like FT8, PSK31, and RTTY. There are also guides for setting up soundcard levels to ensure clean signals and avoid interference. Operators interested in specific digital voice systems can learn about D-STAR, DMR, and Fusion, while resources like PSK Reporter offer real-time reception reports to track signal paths. New protocols like M17 are also emerging, driven by open-source development.

KISS703 is a 703 Hz narrowband digital mode for amateur radio, designed for simple, low-power operation without computers. A 500 Hz pilot tone ensures frequency alignment, replaced by unique tones for 37 symbols (letters, numbers, space). Built from common discrete components, it draws about 40 mA at 12 V, ideal for SOTA/IOTA use. The receiver uses amplification, wave shaping, and a pulse-counting frequency meter for manual decoding via a calibrated meter. Transmitter and receiver calibration involves marking meter positions for each tone, enabling fully self-contained messaging with minimal hardware in portable or fixed operations. -
M17 is a community of open source developers and radio enthusiasts. We are building understandable systems in support of the hackers and experimenters' history of ham radio. M17 is developing open source hardware, software, and offers a complete digital radio protocol for data and voice, made by and for amateur radio operators. M17 voice mode uses the free and open Codec 2 voice encoder. -

OpenRTX is a free and open source firmware for digital ham radios. The firmware is designed with a top-down approach with the objectives of modularity, flexibility and high performance. Currently, it targets some Tytera Radioddity Baofeng digital radios -
Ribbit is a novel digital text messaging mode for VHF/UHF communications for recreational and emergency use which radically increases the density of information transmitted by spectrum used. It leverages the computing power of the modern smartphone to increase the capabilities of any Handy Talkie without requiring any additional hardware or cable. A Ribbit message is fixed in duration at 1250 milliseconds. It is sent over audio modulation with a 2kHz bandwidth centered on 1.5kHz. It is preceded by 400ms of white noise to open analog squelch circuits. -
