About The
Kamiak Butte Amateur Repeater Association

The KBARA repeater system consists of several privately owned linked Amateur Radio repeaters.  It covers an area from northeastern Washington to northeastern Oregon, and from western Montana to central Washington. The KBARA system is also part of the Evergreen Intertie, an interconnected group of repeaters located in western Washington and Oregon. 
See Coverage Maps below.  
The KBARA system can also be connected to the Evergreen Intertie, an interconnected group of repeaters located in the northwestern United States and western Canada. 

The primary purpose of the KBARA repeaters is to provide a means for emergency communications within the above areas, and secondarily for routine radio traffic.  It makes possible a single system of mobile communications coverage, extending the limited range provided by any single repeater operation.

Most KBARA FM repeaters operate in the VHF bands and are linked by UHF radios.  
The repeaters' frequencies, call signs and locations are as follows:

147.380 MHz W7OE,  Mica Peak, east of Spokane, WA
147.360 MHz N1NG,  Stensgar (Stranger) Mt., north of Spokane near Chewelah, WA
147.280 MHz  KD7DDQ, Pikes Peak, southeast of Walla Walla, WA
147.020 MHz N7LVO, Lookout Pass, on the Idaho-Montana border
146.740 MHz W7HFI,  Kamiak Butte, near Colfax and Pullman, WA 
223.900 MHz WA7YCP, Stensgar (Stranger) Mt., north of Spokane near Chewelah, WA
444.350+ MHz, 192.8 N1NG,  Mica Peak, east of Spokane, WA
3957 IRLP Node N1NG, south hill, Spokane, WA

For these maps it is assumed that the receive antenna is located 2 m above ground.  The Lookout Pass repeater is showing a somewhat weaker signal than is my experience.  This may be due to the location used is not exact for that repeater.  Also the Kamiak Butte repeater was run using a 250' high antenna, it is now at 100' which would reduce the coverage for that repeater somewhat.  Otherwise all the input data is good and the model seems to work fairly well.  Hope people enjoy these and find them useful.  If people have comments on the coverage verses their experience please send them to Jim, N7WRR (email:  jashleman at aol.com or c/o N7WRQ at aol.com).

These maps were done by Marty, WB7AFV with data and parameters furnished by Jim, N7WRR.
Thank you both for this wonderful contribution!
