I second the sentiment but I understand the complexity involved in starting from scratch.. I have reached out to the maker via twitter..G7JTT wrote: ↑Thu Jun 25, 2020 10:55 amHow about something like this for tuning ?

A frequency counter that displays frequencies in a dial image.
Detailed customization such as design customization and offset value setting is possible.
It is a frequency counter to be used not as a measuring instrument but as a frequency display built into a radio.
As a built-in frequency counter, there is a cheap kit, but since the frequency display is only numbers, the design is still somewhat limited.
In the days when frequency counters were not popular, frequency display was a mechanical dial mechanism. Making the dial mechanism was difficult, but visually, this "dial" was an impressive part.
Regardless of the frequency reading accuracy, I think that the "dial" is still hard to throw away from a design perspective.
Therefore, instead of the mechanical dial mechanism, the frequency is displayed as a dial image.
2.4 inch TFT color LCD is used for display. The CPU is a PIC32MZEF series with 512kB SRAM, and image processing is performed without an external memory.
It can be connected to a PC with a USB interface and can be designed using a PC application (customization tool). Youtube video :https://youtu.be/e92y0ONECDc
In addition to customizing the dial image, digital frequency, meter image, arbitrary character string, etc. can be arranged by specifying the position.
