The WAX Group consists of members of the Barrie Amateur Radio Club who enjoy building projects for our ham radio hobby from kits or individual parts, instead of just buying ready made. We also promote learning and using CW and getting out of your house to a park or other location to operate (whether it be QRP or higher power, CW or SSB). Webpage: https://barriearc.com/builders-group
