Interesting, could this be done with the standard Raduino that comes with the Bitx 40, or is there additional circuitry here ?
Hello Andrew, Thanks for the comment. Actually Raduino is running with Arduino code, Personally i dont prefer Arduino nowadays. So i port my code into AVR C language. Its a simple modification on existing line of codes. You may request it on BITX group. By the way, receiving CW on BITX is again depends on the bandwidth of ladder filter. My mod is just like, something is better than nothing !!!
