The ZIP of the VISIO file I used to make the decals will be linked here.
I may/will have some spare parts / PCB's - list will appear here.
The photo above indicates 1 - 30 MHz and not 1 - 500 MHz as per the title. This is because the photo is of the unit that has the BPF installed on the PCB limiting operation to the HF bands.
