Also, I fail to see the benefit of running a radio on a supercap, compared to batteries (unless you have to pay for the batteries and can get a "surplus" supercap for free. | |

I tend to think more loosely about the power limits, I haven't studied the specs. I'm remembering btute force powers supplies built in the 70s where you'd take a computer surplus 100,000 Mfd cap and put it on the output of a bridge rectifier and run a mobile radio on it for a few years. Knew a few repeaters like that. I live in the country, when the wind blows the lights flicker, or go out. | |
