Shiro-yama-ko dam is located northern part of Sagamihara-city, Kanagawa-Pref. It takes about 30-40min by car from my home in Machida-city, Tokyo.
I went there last Sunday looking for good place to test my newly developed portable antenna.
When I arrived there, good place has already been occupied by some group from Yokohama. They installed many antennas and been operatimg on amateur bands.
So I could not deploy my antenna there.
I just enjoyed nice view from top of the dam.
The dam was empty. It seems under maintenance.
After that, I drive down to the Sagami-gawa River and found wide and deserted place to deploy my special antenna.
But, unfortunately ery strong and cold wind was blowing so that I could not stand for more than 5 minutes. :-p
I'll try again when warmer sunny day comes.
