Hi 462 Ron and Phriends,
I had great success powering 01As with 5V from a power supply glommed from a discarded computer. There is a standard color cod for "ATX" Power Supply. Usually the black is negative, and red is +5V. Green is +3.3V so if you have a radio with UV199s, This will work. Yellow is +12V, white is -5V, Blue is -12V, therefore, you get everything you want out of this supply except B+, which you can get from the value pack of 9V batteries, which will power the radio for several hours. The 5V and 3.3V outputs are usually 15-25A o you can power a heck of a lot of 01As or 199s with one of these. It will even power a 12V car radio. The one I have puts out 7A for +12V and 26A for +5V and +3.3V. The -5V and -12V are only about 0.5A but that is good enough for bias. The Common negative is at chassis potential.
I mounted an 8 lug terminal strip to the power supply and connected all of the outputs to this terminal strip. Cheap and handy1
