Made a own pcb with si5351 and 1.8Inch Display and a Esp32DevKit1.

You can change the file for add on IF and Frequency BFO.

Memory button is for the start Frequency on startup.

V.1.1 now out, got 20 Pre-Memory's with + and - buttons on pcb

Steps in 10 Hz, 100Hz, 1KHz,10 KHz, 100KHz, 1MHz and 10MHz.

Store the startup Frequency with the Encoder Switch

Flash Files with 20 Mem and + MF 455kHz, 9 MHz and 10.7MHz

MF + 455kHz

https://github.com/RSZ-Nld/VFO-1.8-Inch-Retro-scale/blob/main/Flash-455kHz.zip

MF + 9MHz

https://github.com/RSZ-Nld/VFO-1.8-Inch-Retro-scale/blob/main/Flash-9MHz.zip

MF + 10.7MHz

https://github.com/RSZ-Nld/VFO-1.8-Inch-Retro-scale/blob/main/Flash-10.7MHz.zip

And this Ino file you can edit for MF and BFO Freq
