With relays or a good low Vsat FET, the divider can be driven from a 7808 regulator. With transistors or a ULN2804 darlington array, Vsat is high enough that you might not be able to properly encode 30 meters. Using 5K or 10K pots as part of the divider for each band is worthwhile to allow setting the band voltage correctly. 73, ...
