Back in March, QST magazine published an article about modding a cheap Forty-9er kit from eBay to incorporate a digital VFO. This one has two PIC CPUs on the board, a nice backlit display and comes with a tuning knob but no info on wiring it up. Instead we use the CLK0 output of the si5351 to generate the BFO signal, and inject it into the BitX40 board. Ta The Reset VFO button sets the BFO to central frequency (455KHz); The Turn On/Off BFO button turns on or off the BFO. The correction is no longer stored in the board EEPROM so do not comment out the "VFOsys2" is the original version of a digital VFO with analog dial display by Tj Lab(JF3HZB), which can be compiled on Arduino IDE with Board manager "esp32 ver. DDS frequency change test. rd-h. The sketch will set the BFO frequency depending on the mode (LSB, USB, etc. Thanks for this great VFO sketch. For each channel you connect, you will need a 10nF ceramic capacitor, and of course remove the crystal (if fitted). . Pressing the button again will revert back to the other VFO frequency. https://janoc. Can New Version https://youtu. And finally, the whole device is embedded in a suitable box made of PVC material with a thickness of 3mm and 5mm, and coated with colored self-adhesive wallpaper.
