Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

Vox Recorder  ^pop - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists.

WinMSDSP 2000 - Shareware program to receive and transmit high speed CW (morse code) used in MS (amateur radio communication mode) with MS Windows 95/98 and sound card.

CW Player  ^pop - Simple freeware program generates Morse caracters and Q codes. It needs a sound card and Win95.

WinWarbler - A free soundcard application supporting PSK31, PSK63, RTTY, CW, and Phone operation. It can decode all PSK QSOs within a 4 KHz segment, maintaining a sorted list of heard callsigns; it can simultaneously decode RTTY via soundcard and an external modem, generates CW directly or via WinKey, and includes a voice keyer. WinWarbler interoperates with the free Commander, DXKeeper, and SpotCollector for transceiver control, logging, and spotting.

Zelscope  ^pop - Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit.

Spectra - Accurate spectrum analyzer in the range 0 - 2500 Hz, makes an accurate FFT analysis of an audio signal coming from the soundcard
