There are a couple of wiring mods to do but it only takes about half an hour to complete. Saves having to mount a separate board inside the rig. I found that my AKD is a bit susceptible to alternator whine when using it on /mobile, but that may just be that my works vehicle has a noisy 12V system.

Worth looking into. It's so long ago (20+ years) since I used the AKD mobile, I cannot remember if it suffered from alternator whine. What I do know, is that I cannot have the AKD on whilst I TX on 40m as my TX breaks through on the audio side of the AKD. My Trio is not affected whatsoever.
