This is a short video I made today demonstrating how to use the Reverse Beacon Network to compare your signal on different antennas. The RBN is a very handy tool for the CW enthusiast and for hams interested in testing their antennas and also finding out about propagation on various bands. In this video, I use both an inverted v dipole and a Butternut vertical to transmit a CQ call on 10 Mhz (30 metre band). I then compare the signal reports spotted automatically by skimmer stations. However, on the second CQ call with the vertical antenna, I get an unexpected DX call . . . I will let you watch the video!
