CW Reader Decoder

CW player/decoder and trainer for hobbyists.

It is clean in design and has passed intensive testing without a hitch

The player is powered with 9V DC.

Technical data:
1) Input: DC 9V
2) Tune output frequency: 600Hz~1200Hz
3) Output Power: 0.5W
4) CW audio interpretation speed: 10 ~ 40 (10% error rate) (100% correct, without error speed is 15 ~ 35)
We have a potentiometer at the bottom of the board for error rate adjustment, so as to better interpret CW audio signal:
When we use computer to run CW signal, and when the LED at the bottom left of the board flashes, we use a real-sized screw-drive to turn the potentiometer a little to check whether the content is interpreted same as being handled from computers. If not, change the direction of rotation and try again.
Input keyer: 3.5mm jack
Audio Input: 3.5mm jack (single channel you can use to connect)

Notes: When practicing CW (in other words , the keyer is inserted ), we cannot listen audio

( connecting is prohibited the audio input at the same time ).
