Here are some comments from John (W6NBC):
This CafeCast was recorded in the DigiCommCafe, a virtual ham radio buffet located at the intersection of FAITH and TECHNOLOGY in the beautiful Ozarks of northwest Arkansas. Our purpose is to help build interest in the amateur radio hobby and provide a safe place for hams and non-hams to meet where we all respectfully LISTEN, ACKNOWLEDGE and SHARE within a "Culture of Kindness". Like a buffet, amateur radio has a large menu of entrees that covers the gammut of radio communications. We encourage all our patrons to simply pick what you like and leave the rest. Join our Mighty Network (our very own Facebook alternative at digicommcafe.com) and tell us more about how you are enjoying our great hobby. Sit down with us regularly in our Telegram Voice Chat Studio at K5DCC.com and enjoy your morning coffee in TheCafe. Introduce yourself and meet our regulars. Be prepared to share as we may ask you..."What's Your Story"?

Here's an interesting antenna design for radio amateurs exploring the 630 meter and 2200 meter amateur radio bands. This classic antenna is basically a top loaded vertical designed for frequencies below the standard broadcast band (472 kHz and 137 kHz). Even though this antenna is inefficient, a digital signal using the FT8 protocol should get you some contacts. Good luck!

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio. In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort. Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

Bernie does an excellent job of explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV). Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use. The G5RV is an excellent choice for the 20 meter band. Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.
