Badger Pass Repeater and Site

The Badger Pass site is unique in that it currently does not have commercial power. As such, we have installed a Solar Power Plant consisting of 4, One Hundred and Thirty watt Kyocera solar panels, feeding a 1235 Amp Battery Bank to power the UHF repeater. Badger Pass is an excellant location, at over 7,200 feet, it looks over the Dillon valley as well as west into Bannack and Jackson. Coverage from Idaho to the Divide/Wisdom exit on I15 has been tested, along with MT highway 41 from Dillon to I90 and including I90 coverage from Whitehall to Homestake Pass east of Butte. The repeater frequency is 449.1 input and 444.1 output with 100.0hz CTCSS tone required for access. Because of a couple of areas that overlap with MacDonald Pass on the same frequency, this "non-standard tone" is used at this site only. The repeater consists of a Motorola MSF-5000 and transmits with 80 watts. Because of the high capacity Solar Plant, we operate this repeater on a DC only power supply drawing about 1.3 amps while in standby. The antenna is a Decibel Products DB-420 fed by Inch and a Quarter Heliax. The site is connected via Echolink to the other repeaters in the system.
