SSTV freeware software for Windows by Mako JE3HHT. MMSTV is a free software application designed for transmitting and receiving SSTV (Slow Scan Television) images over HF bands. It allows radio amateurs to share still pictures using sound-card interfaces and a transceiver. The program supports popular SSTV modes (Martin, Scottie, Robot, etc.), real-time RX/TX monitoring, and easy image editing. Its user-friendly interface and reliability make MMSTV a favorite choice among ham operators worldwide. Ideal for showcasing QSL cards, shack photos, or technical diagrams over the ai An excellent SSTV program that requires only a computer with soundcard, no expensive TNC required. Works on all Windows version including Windows XP, Vista and Windows 7.

Computer sound card packet tnc to radio interface. david stansbury kb3kai home-brew version of this soundcard to rig adapter

Presented here is a transceiver to computer sound card interface complete with automated transmit key function. A sound card interface is simply the audio coupling of a computer soundcard and a transceiver to allow various computer applications that send and receive SSTV, RTTY, PSK31 and other similar modes based on soundcard generated signals.

This circuit provides an interface between the Yaesu 920 transceiver and IBM computer sound card which allows data transfer and control of PSK31, RTTY, KEYBOARD CW, and SSTV modes for Amateur Radio

Computer Control and Soundcard Interface for the Icom IC 706

A simple PSK31/digital interface which can connect your transceiver to a PC soundcard for digital modes.

Homebrew your PC sound card to radio interface with this circuit obtained from the pages of Ernie Mills WM2U.

Practival project that contains two isolation transformers, one for AF from the tranciever to the line in on a soundcard, and one from the audio out of the soundcard back to the mic / data input of the radio. Both of which are variable inside the interface via two preset resistors.

Interfacing the IC706MKIIG for Soundcard & TNC modes

An improved version of the audio interface commonly used to connect a computer soundcard to a transceiver\'s receive and transmit audio circuits

The sudden explosion of new digital modes has taken the Amateur Radio world by storm. New modes such as PSK31 FT8 JT65 FSK441, ISCAT as well as established modes such as RTTY, SSTV, Hellschreiber and others have rocketed in popularity. In order to use these modes all that is required is a simple computer-to-radio interface which couples the computer soundcard to the radio

Simple soundcard interface that can satisfy several requirements like totally isolated AF interface, Totally isolated PTT and CW Key interface, Extend Accessory connector to interface to allow easy connection of TNC and provide a solid PTT or SEND connection

A SSTV interfsace (soundcard) to minimize RF feed back and a soundcard limiter to prevent over driving the soundcard
