CWRX, a freeware Windows application, decodes Morse code (CW) signals directly from a sound card's audio input, presenting the decoded text on screen. It supports various receive bandwidths and filtering options, allowing operators to optimize signal reception in different QRM conditions. The program's core functionality focuses on robust CW decoding algorithms, crucial for weak signal work and contesting environments. Developed by OZ1IVA, Lars Harbo, this utility provides a straightforward interface for real-time CW interpretation. It integrates basic logging capabilities, enabling users to record decoded transmissions for later review or contest submission. The software is specifically tailored for the Windows operating system, ensuring compatibility with common shack computer setups. Its design emphasizes ease of use for amateur radio operators seeking a dedicated CW decoding solution. The program's small footprint and direct functionality make it a practical tool for both casual listening and more intensive operating sessions, without requiring extensive system resources.

Contest audio recording for N1MM. external "plug-in" which adds a QSO audio recording function.

A Kenwood TM-D710A microphone (Model MC-59) is producing crackling and intermittent, poor audio so John took a peak inside to have a look around.

The program sends morse code audio via sound card and can be used under Windows in Danish only

QSO Recorder Indexing service. This site allows radio amateurs to share their contest and DXpedition audio recordings, usually made with the N1MM Logger+ and the Qsorder plugin

Ham radio communication in the VHF and UHF bands, which was previously dominated by analog Frequency Modulation (FM), is increasingly incorporating Digital Voice (DV) modes. DV transceivers digitize audio and offer benefits like as signal integrity, encoded caller ID, and bandwidth savings. Today D-STAR, DMR and Yaesu System Fusion (YSF) are popular DV formats, each with its own set of features but mainly incompatible with the others. Internet access with Voice Over Internet Protocol (VoIP) expands DV communication worldwide. Repeaters and personal hotspots expand DV capabilities, enabling seamless worldwide connections. However, implementing DV frequently necessitates learning new technologies and negotiating network complexity.
