I built a different VFO controlled 40 meter transceiver using a Frog
Sounds transceiver, Arduino, si5351 breakout board and an OLED display.
I have several posts with details on my blog.

Hi DuWayne,

Very interesting project. I liked the can enclosure, very creative. How is the performance of your Canned Frog ?
I also noticed that you have some cool projects on your blog, keep us posted.

The receive is pretty good except for occasional BCI that seems to be common in these simple transceivers.? Because I did not have the correct transistor for the final, output is less than a half watt.? Other than getting a couple RBN reports, I have not used it.? I built it as a simple way to test the VFO,BFO? hardware and software for another project that is in the very early design stages.

Nice Build...love the case! The BCI filter (see early photos) I detail will knock the slats out of any local broadcast interference. I have an article coming out on it in CQ Magazine this summer. That version, however, can handle over 100W, which is overkill here. Still, you could build the one here just using axial lead inductors for next to nothing. You can also use less expensive caps since there's little power going through them.
