Richard, it's relatively easy to convert an AKD2001 for sub audible tone use with the eprom kit supplied by Spectrum Communications. It converts the synth to 12.5KHz spacing at the same time, and you will have to turn down the wick for 2.5KHz Tx deviation. I converted mine recently and it works fine. 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.
