So finished testing the VA3IUL circuit on cw . Works great ?, it was so simple and easy to build and key the sine wave output into the mic input with the standard code key in the BITX80v3 . This one does not have a Raduino as of yet , but it is good to go on 80 CW . Now to find a small vintage radio box for it , will post some pics when done. 73s Buzz
