Great websites for learning:
Reddit’s /r/amateurradio – A great forum of operators, both new and seasoned.
HamStudy – A fantastic study resource for your tech license or an upgrade. Tracks your progress on flash cards and practice exams.
Dave Casler, KEØOG on YouTube – Great video series to augment (not replace) the ARRL study guides for Tech, General and Extra. Dave also has a series explaining common questions about amateur radio.
Podcasts I enjoy:
Ham Radio 360: Workbench – A more interesting offshoot of Ham Radio 360
QSO Today – Interviews with notable radio operators
The Engineering Commons – Not directly radio related, but always an interesting in-depth discussion about some topic relating to engineers.
This list will be updated over time.
