I think you missed what the man is saying. He's working with the original bitx20 kit that was around before the Raduino and uses an FLL board with a PIC and LCD display. The FLL also supplies stabiliz

Gary, Is it possible to remove the Raduino and display from the case and connect to the USB port on your computer without the mainboard? The Raduino should powerup and the display should show the norm

Hi Malcom, Thank you for sharing your schematic for the unit. Will check the junk box for parts before ordering parts, or possibly David's kit. I'll check your QST lead for further information. Thank

Richard, Glad is was an easy/not costly fix. Hope to catch you on the air. BTW, here is a good process to follow for BFO calibration: https://www.hfsignals.com/index.php/bfo-tuning-aid/ I would also s

This is one of those kits that has a little bit of work to it - it is NOT a plug in and go (the V6 sounds like it BTW - I think you can even get it assembled and tested for a few $$ more). Unless you

The standard firmware only provides basic LSB functionality. Improved Raduino firmware for BitX40 supporting LSB, USB, CWL, CWU, and other useful functionality is available at https://github.com/amunt
