The antenna on Rocky Top
The University of Tennessee Amateur Radio club has a set of antennas nestled between the lights at the top of Neyland Stadium in Knoxville. The tower is so high, most of the 102,000+ fans wouldn't ever notice it. With the lights on, it's impossible to catch a glimpse. K4HCK
Thank you for my signal report
Maybe this is a radical idea but for my own operation I will strive to start sending more accurate reports and help the other station truly know how they are being copied. AA4OO
Building a feedline HF choke
The choke has a resistance of over 1000 ohms on most of the Amateur HF bands, and up to 5000 ohms in the middle bands. Daniel Estévez
Build an end fed match box
Connected to my end fed inverted L it shows decent SWR on 40 and 20m. My transceiver's built-in ATU easily matched on both those bands. marxy's musing on technology

NVIS event with a fence antenna
I connected to the fence using two alligator clips from the coax, one clipping to the fence and the other clipping to two 33ft radials which ran perpendicular to the fence. VA3OSO
Rowboat mobile
While on vacation in Maine, I borrow a friends rowboat and go mobile maritime off the coast of Maine. I work a nice pile up and finish the day off with fish and chips. KB1HQS
