The next class will probably be either Oct. 5-7 or Oct. 12-14 2018 depending on instructor and VE schedules. I try to schedule them the week before the swapmeet in Rickreall, OR, and those are in Feb. and Oct. The webpage at http://www.n7cfo.com/amradio/hf/hf.htm has a list (thanks N7CFO). Look for "Salem Hamfest" or "Swap-Tober Fest".
If you'd like to be notified when the next class occurs, please sign up here. If I get a cancel from someone registered for the Feb. class I'll try to fill it from this list.
NOTE: the Technician class question pool is changing on 1 July, 2018. Any exam that takes place after that date will use the new question pool. I've looked through the questions and most of them are very close to the current set, but there are some changes. If you haven't bought the ARRL license book yet, wait until they have the new version.
