I use a simple LM317 voltage regulator chassis to provide a 14 volt buss for the radios. The chassis has metering for current and voltage and I use a large meter to monitor the buss voltage when cranking.      - - - Photo below.
 The regulator chassis has a toggle switch to select either Solar Panels or Hand (or Foot powered)  Generator. I built the chassis many years ago when a LM317 voltage regulator was a big deal but the problem is the LM317 is very inefficient with efficiencies of 60 percent for my 14 volt buss voltages (20-24 volts in) and when I use the LM317 for 2 or 1.5 volts the efficiency  really drops and is around 15 percent.
    - - -   Q. Has anyone tried the newer adjustable regulators that are more efficient with claims of 88 percent efficiency such as the LM2576-ADJ?    My biggest concern is that the LM2576  operates at 50 kcs and I am worried about the noise being injected on the line. Its a strange looking device as it has 5 pins.

I made a short video of the power and CW ops.
