Here is the remote controller. I'm quite proud about this. I resisted the urger to use
PIC processors and made it with discrete components. It's made with Johnsson counters.
The first design priciple was to have no external wires and use the coaxial cable to
carry the band data and power supply. This was easily achieved by using 9V supply voltage
and giving the "band change" -data by forming 12V peaks over the 9V. The both Johsson counters
are synchronized, pretty easy ehhh?
There's also band indicators at the antenna side, of course.
