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.
I made the purple one about 10years ago or so , the black one was done a few years ago. I normally mount mine soldered to a tuning can. The groundplane is connected to the tabs in the corners. I wish could have gotten a One Big Punch or a Telstar Voicemax before they were discontinued
