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 required - you need only receiver and computer with a sound card. Can integrate with AALog logger. It is a software morse decoder that really work! CwType: The terminal program for CW-operators.
I'm running XP on a Sony Vaio with a Sigma Tel sound card. I tried running everything through my usual recording set-up which is mic through my effects box, plugged into an indigo audio card (I know, convoluted but I normally need the burly sound processor in the box and it all fits the cables I have) + headphones plugged into the sound card.

Title	Description
BR-universal-Filt	Real time DSP filter particularly for applications of amateur radios IIR, FIR filter, low-pass, high-pass, band-pass filter, band suppressor (notch filter) individually adjustable noise filter, irregular signal filter, hum filter, peak filter frequency tuning and inverting mixer support support of several soundcards (also virtual soundcards) e.g VAC Virtual Audio Cable small file size simple to use multiple language support
MM-DSP Filter	By JE3HHT - Makoto Mori DSP filter with Windows and Soundcard Win95/98/ME/NT/2000/XP/Vista & Win7 (Seems to run on Windows 10, but vendor has not tested.)
RoMac 10 Band Equalizer 2012	The RoMac 10 Band Equalizer 2012 coupled with your present computer's soundcard, affords you the finest Windows based digital equalizer made for the Amateur Radio community. Using professional techniques such as audio equalization will enhance the audio quality of your signal. The RoMac 10 Band Equalizer 2012 is like having a full featured audio studio in one package.
Spectran V2	Spectran is a program to do real time or deferred spectral analysis / waterfall display, in addition to real time audio filtering (band pass, denoising, band reject and CW peaking) of audio signals, using the PC sound card to digitize the input analog signal, or taking as input a WAV file. Its characteristics are well suited to dig weak signals buried into noise, thanks to a selectable bin size down to 21 millihertz. On the opposite site, it can visualize normal CW signals, resolving individual dots and dashes (with a reasonably fast PC).
Audio Spectrum Analyzer ('Spectrum Lab')	This program started as a simple FFT program running under DOS a long time ago, but it is now a specialized audio analyzer, filter, frequency converter, hum filter, data logger etc
Voice Shaper	Voice Shaper is a speech pre-processor for SSB transceivers. It receives the voice signal from the microphone connected to the soundcard, and sends the processed audio back to the soundcard in real time. The following processing functions are implemented in the program: Bandpass filter; 7-band equalizer; Noise gate; Compressor; RF envelope clipper. The configuration procedure of the DSP functions is interactive: the program records your voice, then it plays the recording back through the processor and allows you to adjust the settings and immediately hear the effect of your changes. Real-time spectrum and histogram displays provide the insight into the processor operation and make the configuration process even easier.

CW Skimmer	Multi-channel CW decoder and analyzer for Windows
CwGet	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 required - you need only receiver and computer with a sound card. Can integrate with AALog logger. It is a software morse decoder that really work!
CwType	The terminal program for CW-operators. You can transmit both from the keyboard and from a paddle connected to game or LPT ports. You can also operate in paddle iambic mode. Control of the transceiver (PTT and CW keying) is made through one of the COM or LPT ports. CwType can integrate with AALog software.
G4FON Koch Morse Trainer	When I returned to Amateur Radio my CW was decidedly rusty. What I felt I needed was a CW Trainer to get my speed back. I looked around the Web and found an article by Dave Finley N1IRZ on a method of CW training developed by a German psychologist called Ludwig Koch back in the 1930's. Reading though Dave's article, I decided that it all made a lot of sense. Basically you start off learning the code at the speed you would like to achieve. Unlike the Farnsworth method which seeks to reduce the gap between the letters as you become more efficient, Koch came up with the idea that you should start off just learning two letters at full speed and add an additional letter once you reach 90% proficiency until you have mastered them all. Since you are only learning one new letter or figure at a time, your frustration is significantly reduced. Dave Finley gave a suggested order for learning the letters and figures and recommended a programme called Super Morse to use as a trainer. I quickly realised that Super Morse offered more features than were required to learn Morse by the Koch method and decided to write my own programme orientated towards the Koch method.
Morse Runner	Contest simulator for Windows
MRP40	MRP40 is a powerful and highly-effective ham radio software program that decodes received CW audio that has been fed to a computer's sound card. The decoded text is displayed on the computer's monitor. For transmitting CW, the program encodes keystrokes from the computer's keyboard. Hams use MRP40 to send and read QRQ (high-speed) CW, to help read weak DX signals, and to improve CW contest scores.... With MRP40 you are number one on the air! ...
RoMac CW ID	RoMac Software's Automatic CW identifier and Tuning Pulser utilizes your present computer's sound card to automatically send your callsign at preset intervals, to insure your stations compliance with FCC regulations. Also incorporated is a Tuning Pulser aka Pecker, to aid in reducing stress and heat while tuning your amplifier, antenna tuner, etc.
