BA3QU Recently, I was fortunate enough to obtain a discarded BD6CR Rong teacher's "Do-It-Yourself" kit. After assembling it, I designed a case that integrates the manual key button and 9V battery into a square box. It doesn't require any additional circuitry or accessories; all that's needed is a 3D printed enclosure to use it.
