A program to decode morse code (CW) via sound card to text. It can work as narrow-band sound DSP-filter also. No additional hardware is required, you need only receiver and computer with a sound card. It easily integrates with AALog logger. CwGet is a powerful Morse code decoding software for ham radio enthusiasts, featuring a customizable interface with three main windows: spectrum display, oscillogram, and received symbols. It includes auto frequency control, adjustable filters, burst noise rejection, and supports multiple decoding channels. Users can control transceiver frequency via Omni-Rig and record or replay received signals. CwGet also integrates seamlessly with logging software and other applications, allowing data transfer and interaction through DXSOFTEX.DLL. Additional features include manual and automatic threshold adjustments, zoom functionality, and support for various character sets, making it an essential tool for efficient Morse code communication.

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.

A digital mode decoding and terminal program that uses no terminal unit, terminal node controller, or multimode hardware. It does all its decoding using the sound card inside the computer, and it can interface with a radio using a COM port. Zakanaka is an extremely cost-effective way of operating PSK31 and RTTY

SpectraScope is a simple Windows interface program allowing your computer to view up to two audio waveforms in either the time or frequency domain. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer. The useful frequency of operation is 20 to 10,000 Hz in the time domain and 20 to 20,000 Hz in the frequency domain. The program uses the computer sound card to capture the audio input.
