    Product as described, fast delivery and good quality, Price/Quality is very good. Very nice to get familiar with morse and learning it .Features on the board are very nice : Regulating the sensitivity with pot.meter ,Reset button and space decode on/off switch. On the right side 9VDC input (Top) and the input signal to decode, On the left side a Speaker connection and morsekey input.(Top) You need to connect these inputs and outputs with stereojacks. Also easy to remove the display module. The signal must be very clear and well-formed before decoding !!! You can find all the pros and contras,also instructions and informations on the internet. Recommended !!

    In order to fine tune it please do the following: 1. Remove the LCD by gently lifting the LCD header pins out of their sockets 2. Turn the LCD adjust all the way counterclockwise and then back clockwise a few degrees. 3. Replace the LCD. 4. Plug in a 9-12 volt power source into the power input plug. 5. Note whether the LCD is too dark or too bright and adjust accordingly with the LCD adjust. 6. Find a CW Morse Code player online and download it to your computer. 7. Create your text message to be played as Morse code Audio. 8. Connect a cable between your computer’s audio output to the CW decoder audio input. 9. Connect a cable between the CW decoder’s audio output and a speaker or just use a headphone set. 10. While the CW player is running, you should hear it playing, but may not see anything on the screen but a string of “I’s” and “E’s”–believe it or not, this is a good sign. 11. Turn the tone frequency adjust all the way clockwise. 12. Set your CW player tone to 690 Hertz on your computer. 13. Set your CW player speed to 22 words per minute. 14. Set your computer volume to 50% or Lower 15. Push the reset button on the CW decoder. 16. At this point, you should now see the CW decoder operating as it should, reading off the CW file you are playing on the CW player on your computer. 17. Tap the red character spacing button to select either “no spaces” or “single spacing”–single spacing works best for reading. 18. At this point, you can vary the CW player tone frequency, the CW player speed and the computer volume to get the best audio signal to your CW decoder.

    Classificação do produto 0. trabalhou menos de quatro horas em quatro meses e parou. E mesmo o casco que ele fez parece e não é necessário quebrar. O sinal vinha da saída do computador. 9V da fonte de alimentação. Condições do ambiente. Decepção total com tal técnica.
