Western Washington Medical Services Net

Click here for Mason County Amateur Radio Club nets.

The Western Washington Medical Services Emergency Communications Team was created in 1990, following the Loma Prieta earthquake in California. The organizers realized that western Washington was as susceptible to large damaging earthquakes as is California. Since then, teams in multiple counties in western Washington have been started, and more are joining in. For more information, visit the WWMST website.

On the first Thursday of each month, the WWMST holds a directed net on the new and growing K7MMI repeater system. For the central Puget Sound region, the frequency is 146.980 MHz, with a negative offset, and a PL tone of 107.2 hertz. For the south Puget Sound region, use 147.200 MHz, positive offset, and PL tone of 103.5 hertz.

The WWMST holds a weekly net on Thursday at 2000 hours on the W7SRZ repeater system. This is a directed net, and visiting stations are welcome to check in after regular net business has been completed. The following frequencies are linked for the weekly WWMST net, however, system upgrades are underway. Consequently, some connection problems are bound to occur, so it is possible one or more of the frequencies may not be fully functional.

146.900 negative 103.5 VA Hospital Seattle
443.550 positive 103.5 VA Hospital Seattle
