Heard VP8GEO 569 at 0617z today, calling CQ with no takers. When I touched the key there was no output -- apparently my 24VDC power supply that powers various switching relays had conked out. By the time I recabled the coax directly to the amp, he had gone up to 80m and stayed there through their sunrise (0650z). Sure glad I don't need this one! 73/Jon AA1K
