I have first licensed in 1966, when I was 15. Starting on 15 meters with 9R59 and home brew 2E26 AM Transmitter. I soon learned CW. With some blank period, I got TX-599 and JR-599 which were the first generation silver panel Kenwood line up. I was getting all the amateur licenses and finally in 1973 reached the first class license. With that, I got FL2100B and 500W station license. I was active on 160m also with 2E26 Transmitter + 813 x 2 amp.

Also my old good days was RTTY. I made TU with 741 Op amp and troid cores. The printer was Teletype corp MO-19, which run 50 baud. So I needed 45.45 to 50 baud speed converter. That was my first TTL logic experience. I had only one DX QSO with Guam.

I had some UHF/430 Packet radio experience in 1990's, connecting to the Internet via PRUG (Packet Radio User's Group). With that my interest went to TCP/IP world.

Then, with about 30 yrs. blank period, I have resumed the HF Radio activity in 2008 with IC-7000. I got some land in Kimitsu city and since 2009/09, I have motor drive scopic tower. For now, NA-440 (Nagara 40m) CL6DX (6m) 4SDX (Mini-multi 20/15/10m) are on that tower.

I am focusing on contest only, and mainly active on 40m CW with some exceptions as 160m/10m/6m. Main Rig for now is TS-590S.
