You dont really need to take a class to pass the test, but it wouldnt hurt, and you might find it interesting. If you just want to pass the test, get the W5YI Gordon West technician handbook. After a few hours study you should easily able to pass the no-code technician exam. As for equipment, 2 meter (144mhz) radios are as cheap as their ever gonna get, You can get any of the major manufacturers (Icom, Kenwood,Yaesu) 2m rigs for under 150. 00. With an inexpensive 2 meter rig and good antenna you will be able to hit lots of repeaters in your area which will give you up to 150 mile or more range (I bet there are several moutain top repeaters in the Seattle area that have tremendous coverage. ) And if Washington is anything like California, there are many areas where cell phones dont cover and an amateur radio transceiver can be a lifesaver. Last August, while camping with my sons near the Carson Iceberg wilderness area, (Highland Lakes, CA) some guy fell outta his little canoe in frigid snowmelt water, he barely made it to shore and was in really bad shape from hypothermia, there were 4-5 people there with cell phones, and NONE of them worked, I was able to get out on 2 meters to a ham near a land line who was able to call for help. If you hang out in the high country like I do, a HAM radio can be a lifesaver.
