NMC - Ninemile Creek Instream Array

Ninemile enters east side of Lake Osoyoos at Okanogan River RKM 129.5, north of the town of Oroville, WA. Site NMC is located on Ninemile Creek, 0.78 km upstream from the confluence with Lake Osoyoos. The setup consists of 4 pass-through PVC antennas in series. Antenna sizes are as follows (upstream to downstream): Ant1 7 feet, ant2 9 feet, ant3 9 feet, ant4 11feet. The site is on grid power. Two banks of 12volt batteries in series create 24volts to run the MUX unit. The batteries are connected to a timer switcher that will switch battery banks every four hours. The battery bank not running the MUX unit is then charged to capacity using a three-stage battery charger. The NMC site has remote communication abilities provided by a Raven XT cellular modem. This allows access to data through Hyper Terminal.
