- Are you going to add a small gas generator up there or are the rangers going
to have to switch out the batteries if there is no sun for 2 days. Also how
about adding a new wind turbine, they are very efficient and have many
safety overrides that keep the speed down.
Also how will the rangers keep an eye out on how the equipment is working?
How about adding a APRS Station with telemetry?
Is anyone doing any scout related stuff at Field Day?

> The repeater sits on a 3000+' remote mountaintop out in the

> mountainous terrain with five lakes and ponds, and it is a winding,
> almost five mile drive from the ranger's HQ to the summit. The repeater
> (GE Mastr II) was powered by a windmill and a homebrew gasoline driven
> 12v generator that charged a bunch of really old used 200 amp bus
> batteries. Someone had to hike up (no Gator then!) every few days to
> run the generator for a few hours, since the wind wasn't reliable
> enough, and winter ice and winds tore the blades off the windmill. That
> wore pretty thin after one season, and they pulled the system off the
> hill and put it at the ranger's HQ on a 80' tower - the lowest point in
> camp, and at the southern-most tip of the reservation. Coverage was
> pretty poor from there, especially out in the northern back-country.
> Last summer we began planning a return to the mountain, this time with
> solar power. On Sunday, after a winter of planning and preparation, I
> took the reservation's new John Deere Gator up the mountain (a 45 minute
> bone-jouncing ride from HQ) and installed two new Siemens 100 watt
> panels on the side of the old windmill tower. Next trip we will string
> a new support cable and some #8UF cable to the fiberglass equipment
> shelter which will house the MII repeater, solar charger/controller and
> new deep cycle "bus" batteries. By design, the solar system should
> provide enough power for a 50% transmit duty cycle for two days without
