Ham Member Lookups: 7833


1.  I got ham licensel in 1960 when I was young student of University. I used homebrew rig and antenna when started my ham-life: Xtal-6BA6-6AR5 COPA TX runing 5w and 1-V-1 Receiver. Through my long ham-life I have been interested in Low Band DX mostly by CW. Several times I have to QRT because I was very busy in my work. Since 2006 I retired my work and have a lot of times for enjoying Low Band DXing. Now I am especially interesting in 160m DX, but my house yard area is not sufficiently large to extend antenna for 160m. Then, I borrowed my neighbor's house yard for extending 160m antenna. I also interesting in 6m DX and using 7element yagi with 500W amp. Please pick up my sigs when you find it in pile up of JAs.

2.  After, the nuclear power plant accident in Fukushima caused by big earth quake and tunami 2011, I interested to natural power source sysytem. Then, I tried to build up solar and wind power generation sysytem by myself. As showing in pictures bellow, it is mounted on the roof of my house (top picture). The charge controller and battery box is put on the ground (upper middle picture). It also needs non-power drive antenna system. An wide-band vertical antenna (CHA-250BX) meets this request (lower middle picture). FT-897D (sometimes IC-703) transceiver with home brew transmatch in my shack is driven by this natural power source sysytem and is now active all bands especially in contest. Of course, I have another high-performance rig powered by commercial AC line, using for low band DXing.
