Since you are only learning one new letter or figure at a time, your frustration is significantly reduced.ĭave Finley gave a suggested order for learning the letters and figures and recommended a programme called Super Morse to use as a trainer. 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. Basically you start off learning the code at the speed you would like to achieve. Reading though Dave's article, I decided that it all made a lot of sense. 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. What I felt I needed was a CW Trainer to get my speed back. When I returned to Amateur Radio my CW was decidedly rusty. CwType can integrate with AALog software. Control of the transceiver (PTT and CW keying) is made through one of the COM or LPT ports. You can also operate in paddle iambic mode. You can transmit both from the keyboard and from a paddle connected to game or LPT ports. It is a software morse decoder that really work! No additional hardware required - you need only receiver and computer with a sound card. It can work as narrow-band sound DSP-filter also. Multi-channel CW decoder and analyzer for WindowsĪ program to decode morse code (CW) via sound card to text. Real-time spectrum and histogram displays provide the insight into the processor operation and make the configuration process even easier. 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. The following processing functions are implemented in the program: Bandpass filter 7-band equalizer It receives the voice signal from the microphone connected to the soundcard, and sends the processed audio back to the soundcard in real time. Voice Shaper is a speech pre-processor for SSB transceivers. 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 On the opposite site, it can visualize normal CW signals, resolving individual dots and dashes (with a reasonably fast PC). Its characteristics are well suited to dig weak signals buried into noise, thanks to a selectable bin size down to 21 millihertz. 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. The RoMac 10 Band Equalizer 2012 is like having a full featured audio studio in one package. Using professional techniques such as audio equalization will enhance the audio quality of your signal. 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. Win95/98/ME/NT/2000/XP/Vista & Win7 (Seems to run on Windows 10 & 11, but vendor has not tested.) Support of several soundcards (also virtual soundcards) e.g VAC Virtual Audio Cable Noise filter, irregular signal filter, hum filter, peak filter IIR, FIR filter, low-pass, high-pass, band-pass filter, band suppressor (notch filter) individually adjustable
Real time DSP filter particularly for applications of amateur radios
