Hasak CW Keyer: using a QRQ CW Keyboard APP with an audio derived keying circuit that keys the Hasak

[Chuck aa0hw]

test to see how well an audio derived cw keying circuit, like one of these:

https://qrqcwnet.ning.com/forum/topics/what-circuit-for-computer

can "key" the HASAK CW KEYER's straight key pins...and allow a software CW KEYBOARD to be used to "key" the HASAK CW KEYER https://github.com/recri/hasak

(the cw keyboard used in this example is from recri keyer)

https://github.com/recri/keyer

since the HASAK CW KEYER has its own usb sound card built into the code/teensy board....the native laptop's sound card can be used to send cw audio at 6Khz to a simple circuit that can key the teensy hasak CW Keyer straight key pins...
