Mt. Baker Amateur Radio Club Repeater Group                                    



         The repeater group was founded in 1974 by W7ISX Tony (sk).  W7UMH Jim , W7LXP Danny (sk) ,W7YEQ Bill (sk). and WA7BAY ( W7NP ) Mike. We are a semi-autonomous group within the Mt. Baker Amateur Radio Club Inc., we have our own elected officers and bylaws. The first machine was on the freq. 146.730 Mhz on Mt Constitution Orcas Island, Wa. and was put on the air in late 1974.  In 1978 a repeater was added at King Mt. just north of Bellingham on 147.150 Mhz.  The repeater group now has three repeaters on two meters and three on 70 cm or 450 Mhz. The repeaters at the Mt. Constitution site are the 146.740 Mhz  offset minus .600 kc and the 444.050 Mhz offset plus 5 mhz machine.  These machines can be cross-linked if needed by the control operator. These two repeaters are classed as wide area coverage.   The group has two local coverage machines in the King Mt. site on 147.160 Mhz offset plus .600 kc and 443.650 Mhz offset plus 5 Mhz they provide local Whatcom county area coverage and used for local communications, along with ARES and  ACS operations. The 147.160 Mhz repeater has a link to the IRLP worldwide network ( node 3276 ). The 443.650 Mhz  repeater is linked to the W7UMH 53.090 Mhz six meter repeater on Lyman Hill. In Oct. 2002 a UHF repeater on 443.750 Mhz + 5 Mhz and 103.5 Hz PL was added to our system on Lookout Mtn. south of Bellingham near No. Lake Samish this is a wide area coverage repeater. Then in Oct. 2003 a second 146.740 Mhz repeater was added to Lookout Mtn. site. This repeater uses a PL tone of 127.3 Hz and the Orcas Island repeater uses a 103.5 Hz tone. The two repeaters share the same frequency and the user selects which machine by the PL tone used. To tell which machine one is listening to, is by the COURTESY  tone sent by the repeater. The Mt. Constitution repeater sends the CW letter “T” or a dah, and the Lookout  repeater sends the letter “K” or dah-dit-dah.  In August of 2010 both the VHF and UHF repeaters on the Lookout site were relocated to the Squalicum Mt site, Squalicum Mt. is located about 5 miles north east of down town Bellingham. This move was done to allow the Whatcom County Sheriff Office ACS to install their 146.700 and 440.475 mhz D-STAR repeater system at the Lookout site.
