Historically, I’ve operating contests and DX’ed quite a bit. Most of my contesting took place at W5EHM/N5XU, the station of the University of Texas Amateur Radio Club, but I’ve also operated from W5KFT, K5TR/WB5VZL, N3BB, N5AU and 6D2X, often as part of multi-operator efforts. So if you see a callsign other than my own you can be certain it was a multi-op effort.
Here are some of those results:
