This interface is intended to be used with all the popular digital modes like PSK31, RTTY, Olivia, etc., which modulate a continuous carrier.

A homebrew project about a bluetooth interface to connect a transceiver to an audio headset.

Presents RigOne, a radio controller application designed for Windows 10 (later releases) and Windows 11, with a macOS version under active development. The software provides core operational controls such as tuning, VFO following, signal metering, and audio management, emphasizing a clean interface for everyday use. It supports native Icom direct control, with the **IC-7300** serving as the primary tested profile, and integrates **Hamlib** for broader compatibility across various transceivers. The resource details specific features, including frequency and mode read/write, VFO A/B switching, quick mode/band selectors, and switchable analog-style or horizontal-bar signal meters. For the IC-7300, RigOne offers an integrated panadapter, waterfall display, native VOX control, and Twin PBT controls, leveraging live scope data for an enhanced visual operating experience. The application focuses on essential functions, avoiding unnecessary clutter. It outlines the latest version, v1.2.5.1, highlighting updates like a compact layout selector for Tall mode, direct frequency entry, and refined fixed 16:9 panel layouts. The page also clarifies hardware compatibility, noting extensive testing with the IC-7300 via USB/COM CI-V, and invites user feedback for expanding Hamlib support to other radio models, ensuring the software evolves based on real-world amateur radio station use.

The Baofeng UV-5R handheld transceiver, introduced around 2012, operates across the 2-meter (144-148 MHz) and 70-centimeter (420-450 MHz) amateur bands, offering dual-band receive and transmit capabilities. This review provides an early assessment of the radio's form factor, user interface, and general performance, noting its compact size and the inclusion of a **VFO/Memory mode** button for frequency management. The device supports both FM and narrow FM modes, with a reported power output of 4 watts on VHF and 3 watts on UHF, making it suitable for local simplex and repeater operations. Key features discussed include its 128-channel memory capacity, a built-in VOX function, and a **DTMF keypad** for tone dialing and repeater access. The review highlights the radio's ability to scan frequencies and memories, along with a dual-watch function allowing simultaneous monitoring of two frequencies. Battery life is addressed, with the standard 1800 mAh Li-ion pack providing several hours of operation depending on transmit usage. Initial impressions cover the radio's construction and the clarity of its LCD display, which shows both A and B band frequencies.

This project uses an inexpensive Teensy microcontroller as the core of a flexible interface that provides a high-fidelity sound card and VOX functions for controlling the radio.The interface firmware supports variable VOX delay, CW and RTTY keying via audio (such as is available from Fldigi), and RTS and DTR control of any keying function, all via a single USB connection to the PC.

Cheap and easy to build digital modes USB interface for Ham Radio. The DuinoVOX Arduino powered digital modes USB interface for ham radio.

This interface is perfect to operate the ICOM IC706 MKIIg with a pc-headset,in VOX or with PTT.

The N7YG Digital Engine, functions as a streamlined digital modem, supporting **PSK**, **RTTY**, and **MFSK** modes. It eliminates many ancillary logging and awards features found in other software, focusing instead on providing a dedicated digital interface. The software is specifically engineered to complement the N3FJP logging suite, offering a simple digital modem with a floating waterfall display that can coexist on the same screen as the logger. The application includes support for PSK Reporter, EXTFSK, TinyFSK, and K1EL Winkey FSK, enhancing its utility for various digital operations. Key features comprise a separate waterfall window, a main GUI with operational controls, receive and transmit display areas, and 10 Macro Buttons across 10 user-definable macro banks, totaling 100 macros for general and contesting use. Configuration options include sound card selection, digital gain (0-32767), AFC Level (0-100), AFC Width (in Hz), and COM Port TX keying for VOX/SignaLink or direct port control. Input and Output Mixer buttons provide direct access to OS audio mixer controls for precise level adjustments. The software is digitally signed with a security certificate, aiming to prevent conflicts with antivirus programs.
