K3JLS has the solution to N4YG's leaving the market. I just reached out to Joe ('YG) and inquired about buying a dozen or so of his PCBs and programmed PICs. Steve and Dave, you may wish to do same for your rigs...I'll build them for you when I ramp up "production" on the stuff I'm planning to buy.
