This is the University of California Berkeley Amateur Radio Club Station, original call in 1914 6XB. I was QRP at 5 watts. And not exactly a DX, as it was only 113 miles. But, hey, there's a lot of radio history in that 113 mile contact. Check out the W6BB Zed page. This is what makes it fun for me. W6BB circa 1920: But today they use modern equipment!
