Great job!
This is going to get a lot better. How about a stabilized synthesizer reference, 4 RX IF bandwidths (front panel selectable), 4 AGC settings (slow/med/fast/off), also front panel selectable...a mic gain control, possibly an IF Gain or RX tone control. Or maybe a variable filter bandwidth control. The front panel will look stock, albeit with concentric controls for the extra functions.

And the coup de grace: One of those cases will end up housing an SBE LCB-8 as the AM section of the deal. It, too, will look "stock". All mods will be reversible and the channel/clock display will mimic the Stoner's:

CH19A-12:00P

The "A" and the "dash" are going to indicate whether or not the rig is tuned to an RC channel, or is on the "normal" 40CH allocation. A "L" and a "H" range will be provided, and the transmitter will be locked out on all of those ranges unless the planned 80/40/20/17/15M transverter is connected and powered on. Similarly, a lockout will exist within the Pro40 itself: Old man Stoner had the synthesizer programmed so that grounding a pin will enable coverage to 27.865. Unless a transverter is connected and activated, it'll only RX on those frequencies once I'm done with it.
