Gareth, I like your portable repeater! Is it Yeasu/Vertex based? I agree that an RSSI controlled repeater could be problematic for outlying areas, so if it was implemented, we would want to take careful steps to make sure it was appropriate. My thinking was that the relatively small footprint served by a portable repeater with marginal antennas and low power output might militate towards limiting the power. Of course, any low power units trying to hit the repeater would tend to make it vote towards higher power output, so maybe the wisest course would be to just set a fixed power, or offer the repeater owner remote power level control. I am trying to make a unit significantly smaller and lighter than your 22 pound machine, so power savings is going to be an issue!
