>>652060Ah... been there, done that.
Tracked ATV might be a better choice over a snowmobile, depending on the terrain and amount of snow.
Are you sure it's without power, or did a controller/repeater die? Or some other equipment failure (Combiner, antenna, feedline, power dist.)?
Do you have anything alive on the site? (POTS? IP? Microwave?)
If it's a digital (P25 or DMR) system, I'd set up a 2nd/3rd repeater temporarily and link them over IP or P2P microwave until you can get to the primary and get it back online. Slam in the codeplug the primary's got with a few tweaks (site name and IP, mostly), dial in the combiner, get an antenna up, and let 'er go for a while. FCC's usually pretty good about amending licenses in emergency situations, especially for emcomms. Primary license may even allow for that already.
District I worked with bitched and screamed about all the "extra shit" I was buying (RTCM's and power control relay modules mostly)... until "Hey, ___ equipment isn't working, when can you get up there and check it out?" ... remote in from my house, see what's going on, and had the system back up in less than 15 minutes... they quit bitching about the "extra shit" after that incident.
