“Dummy Loads” is the topic of the new (August 16) episode of the “ARRL The Doctor is In” podcast. Listen…and learn!
Sponsored by DX Engineering, “ARRL The Doctor is In” is an informative discussion of all things technical. Listen on your computer, tablet, or smartphone — whenever and wherever you like!
Every 2 weeks, your host, QST Editor-in-Chief Steve Ford, WB8IMY, and the Doctor himself, Joel Hallas, W1ZR, will discuss a broad range of technical topics. You can also e-mail your questions to doctor@arrl.org, and the Doctor may answer them in a future podcast.
