Mobile multi-network radio client for licensed amateur operators
QSO One, from Frank KD8JKK, is a mobile and desktop communication client for licensed amateur radio operators designed to remove hardware barriers. The app connects to multiple digital voice networks and provides live mapping, integrated logging, and audio recording in a single interface. Key tools include Net Finder, Net Runner, and QRZ/HamQTH lookup. It targets hams who want to join AllStarLink, EchoLink, DMR, Fusion, or M17 without hotspots or Raspberry Pi setups.

What networks the app brings together
QSO One aggregates multiple digital voice systems into one client, offering direct access to AllStarLink, EchoLink, DMR (BrandMeister, TGIF, FreeDMR), Yaesu System Fusion reflectors, M17, and IAX Direct connections. This consolidation replaces running separate clients or custom gateway hardware, so operators can use an Android device or Windows machine to join networks that normally require dedicated nodes.
How it handles privacy and account requirements
Transmission requires a valid amateur license, and the app enforces that restriction for on-air use. The app also supports listening and directory browsing without transmit privileges. Network connectivity uses automatic proxy fallback to operate behind CGNAT and mobile firewalls, a fact that reduces the need for manual port forwarding while keeping authentication tied to licensed callsigns.
How notifications, nets, and logging fit real workflows
Net Finder and Net Runner focus on scheduled activity and recordkeeping. Net Finder locates upcoming nets and sets reminders, while Net Runner transcribes nets in real time and logs participating callsigns. Integrated QSO logging pulls details from QRZ and HamQTH, so logs can include station data without exporting to separate software. The recording feature captures audio for later review when operators need a record of contacts.
Cross-device reach and onboarding friction
The app supports Android 7.0+ and Windows, which eases mobile and desktop use. The Material Design interface aims to replace legacy tools with a consistent UI, which helps operators familiar with multiple legacy clients adapt more quickly. The developer notes versions for iOS, macOS, and Linux are in development, indicating the current reach is limited to the listed platforms.
QSO One is a practical choice for license-holding hams who want hardware-free access
The app is a practical option for licensed operators who need direct internet access to digital voice networks without building or buying node hardware. One consideration is current platform availability limited to Android and Windows, so users on other systems must await planned ports. As a mobile-first client that centralizes nets, logging, and recording, it suits operators seeking a single-device workflow for routine on-air activity.
