I have no clue what MPAS2.0 or Yaesu817 are, but can you run a transmitter amp on a 100watt solar panel? Seems like anything that will carry would suck a lot of juice. I’m guessing one of those acronyms has to do with repeaters.
I haven’t keyed a mic in decades and even back then it was local cb squak
Chameleon MPAS 2.0 is a portable antenna system designed to allow portable operation and breakdown to fit in a backpack.
Basically you don’t run directly from the Solar Panel, the solar panel connects to a small charge controller, which is constantly charging the battery and you connect the radio to the battery.
The battery I have is the size of a brick and provides 12 amp hours of power, it weighs about 7-8 pounds. It’s a LifePo4 battery, basically lithium iron phosphate.
Yaesu 817 is a 100 watt portable HF radio, that operates on the Ham Bands like 20 meters. You need a General Class Ham license to operate on these bands, which I have. The radio only pulls 1 amp for listening and when I adjust the power down to transmit I can operate hours and hours in daylight and at night for basically listening and occasional transmit, it works well.
