Jeff Anderson sells those CB splitters custom made for each model Miata EXCEPT the MSM. He is out of stock and lost his supplier so I bought a splitter and tried to do it myself. It works but it is way out of tune (whatever that CB meter thing is that I have tells me this). Anyone know how to get it closer in tune? I'm sure you just throw a resistor on the variable pot but I would have no idea how big to try. I would ask Jeff but I don't want to bug him seeing as how I am building something he normally sells. Any ideas?
