CW Get! Decoding the Morse alphabet
The author of the CW Get program is UA9OSV, Sergei Podstrigailo. It was I guess the first program, which in the Windows environment allowed morse code decoding through a sound card. Ide o shareware, that is, a freely distributable program with certain restrictions. After paying the registration fee 35$ you get the full version.
System requirements are not high: Windows 95/98/NT/2000, procesor AMD 5×86-133 or Pentium-75, 16 bit sound card. CW Type is used for broadcasting, which looks very similar.
The program workspace is divided into three parts: spectroskop, a list of received text and a signal level meter. In the upper part there are six buttons with the most used functions, at the bottom is a status bar with the current settings.
Mark the desired signal by clicking the mouse on the spectrogram. If AFC is on, the program automatically adjusts to it. DSP FIR or IIR filters can be used to eliminate interference, burst filter (ANICO Slovakia – eliminates disturbing impulses, etc.) and manually setting the detection level, What improves the quality of the received signal and helps in decoding even weak or disturbed signals.
If the program algorithm finds CW marks on the selected frequency, in a moment, after detecting the transmission speed, they will start to appear as text on the screen. The program can also tolerate fluctuations in transmission speed, imprecise keying or QSB. If something doesn't decode, it will appear in the text as periods and commas in brackets, so you can guess for yourself, what a sign it is. Decoding accuracy depends on the quality of the received signal and program settings. For best results, it is important to properly tune the receiver and optimize CWGET settings.
CW Get is my favorite – I used it since version 1.0 and I am satisfied with it. The propagation along with the DK0WCY beacon was very helpful in determining the conditions. Highest received speed, what I had the opportunity to try was about 270 LPM, whether he can handle even the declared speed 5 000 LPM (napr.MS) I leave it to you to try.
