Installation of Non-Stop radio operation system

By the end of last June, BHN Association installed a non-stop power system for the broadcasting station in the Town of Watari.

Until then, once the commercial power supply is suspended, it was always necessary to manually start again which needed some person to rush to the radio station at night.

The system is composed of 6 high-capacity batteries in total for the radio emitter & antenna, automatic power chargers and other equipment.  To minimize the cost to install the system BHN has hand-fabricated the non-stop power circuits(which cost around $10,000 in the market).

With the installation of this non-stop operation system, they are now able to continue broadcasting over 8 hours at the time of blackouts.   This work has been realized with the funds from Global Giving .

Almost the entire radio system in Watari broadcasting station was built by BHN and they are planning to transform from a “temporal radio station” to a normal “community radio station” next year.

BHN is now consulting with Ohtuchi broadcasting station(in Iwate Prefecture) to improve the listening difficulties in the mountain areas and, after fixing the listening problem, we also intend to install the same non-stop power system there.
