Following the original by JF3HZB (PW October 2022 p56) I have bodged mine sort of based on the original
I will use for bench signal source and an older direct conversion radio setup I have.
The ESP32 I used seems to be a bit different.
The upload speed 115200, 240MHz, 40Mh flash, 4MB flash
Anyway programmed it.
I used a 2" rotary controller as per the PW article. Ruler and JLCPCB squeaky duck for size comparison.
