 Having now sold off the 16mm garden railway, time to pick up the
 threads of machining for my 50-year-long RX project!
 I was considering the possibility of mixing an si570 VFO with
 an Eddystone-type tuning dial, which would mean a 4096 Gray
 coded disc so that when power is re-appllied, the si570
 can be retuned approximately right!
 Why did you sell off the railway? Sounded like you'd spent a lot
 of time building that up.
My guess is he needed the cash.
