Batboard

It's getting to be storm season here and going though the spare quantar boards for the system, I see different firmware versions on the various boards.

Is there a sheet listing the compatibility of rev's? Like Exciter, reciever, control, wireline and codeplug?

Is it simple (and cost effective) to buy new firmware for all the boards to ensure compatibility.

I don't want to be pulling my hair out at 2am swapping boards that are incompatible. We are just doing analog voice, nothing special.

Thanks
