Someone needs to replicate these boards, they're a nice addition to a lot of radios.

I'd spend the dough to make some but not enough time to spare for a project like that.

Lester copied the board and is selling it for more than Bob originally sold it for. My version is not the exact same but works the same. I didn’t add the relay , I just repurposed a radios switch for the on and off. Lester likes copying other people crap and selling it as his enhanced models. Funny he didn’t copy the Top Gun CP1 or the MD1 he installs.
