About‎ > ‎


I passed the phone class radio amateur exam in March 1971 just after I finished primary school and I got the operator license in June. My station JH3PRR was first licensed in September 1971 at Suita city with only 6m AM 1W handy transceiver and 5 element Yagi on the roof directing toward central Osaka (and VK:-). I got 2nd class radio amateur operator license soon. I upgraded my station license to HF 100 just after I graduated junior high with TS-520S HF SSB/CW 100W transceiver. My father built 12m tower and put 6m 5 element Yagi for me. I built only an inverted Vee for 40m and a dipole for 10m. I watched HF but rarely operated during my high school days.

When I entered Osaka University in 1977, I joined JA3YKC. (to be added later.)

After I finished the graduate school, I joined the gigantic telephone company and spent ten years in the lab in Tokyo.

Then I came back to Osaka. (to be added later.)

In October 2005, I moved to Mt. Rokko, Kobe, the current QTH.
