DIY Radio Builders Group

New for 2023 - DIY Radio Group
NanoVNA Small Group Hands-on Workshops 

Our NanoVNA Workshop participants will gain experience using the ~$60 NanoVNA as a HF/VHF/UHF antenna analyzer, as an RF signal source, and to measure components, amplifiers, attenuators, filters and transmission line characteristics and faults.  Use SimSmith and NanoVNA computer software. Watch this page and join our groups.io forum for updates.
