BG5GNN Well, since I've been back in Hangzhou for over a year, I've noticed some significant differences in the local and regional U-band repeater usage compared to my previous experience in Beijing and other areas of Central China. Recently, I've been using more shortwave frequencies. I haven't yet set up an antenna for the V-band, so I mostly just contact people near Binjiang, and I don't want to bother them with CQ calls.
