I was down in San Diego for work and had a few hours to kill before an event, so I drove over to this summit for a quick activation. There is a parking area just below the summit and it was busy so setting up an antenna was a bit tedious, but I ended up placing my mast behind a wall and ran the end fed along the wall so no one would get caught in it. I spotted, called CQ, and made some quick contacts on 40 meters. This was my first encounter with what is known as a “lid”. I checked to make sure the frequency was clear, so I’m not sure what I might have done to wrong this person, but I’ve added the recording of the odd behavior here. Luckily, K6CWC helped me through the interference, and I went QRT shortly after.
