In the city of Natori which suffered 1,000 human loss and 5,000 buildings destroyed by the Tsunami in 2011, BHN has been assisting the municipal government to move and install new radio broadcasting systems since about a year ago. BHN’s functions in the work were to design the system configuration, to assist the bidding procedure for contract and to supervise the construction works done by the contractors.

By December last year, the studio structure was completed and the broadcasting equipment was installed and it is now ready for practical operation which will commence very soon.

After the completion of all the contracted construction works, BHN plans to donate UPS (Un-interruptible Power Supply) systems for the studio and radio emitting station soon in the course of January - February.

From time to time, BHN is requested to resolve technical problems in other broadcasting stations in Tohoku area. Among other technical troubles the failure with the Amplifier Limiter is the major cause of claims from the audience.   To quickly fix such Limiter failures, BHN plans to equip a spare Limiter in the city of Natori which will be shared by other broadcasting stations in the Tohoku area, as the city is located in the center of the area.

Another Non-Stop Power Circuit was Installed

The town of Ohtsuchi, which suffered heavy damage by the Tsunami, is a typical hilly coastal town in Iwate Prefecture and many of the temporal houses for the Tsunami victims were built and scattered in the valleys.

BHN built the broadcasting antenna on the highest peak in the town, however, the broadcasting radio wave could not reach well to many of such scattered temporal houses.

Under such circumstances, BHN is now discussing with the town to establish a fundamental solution and, as its 1st step, installed non-stop power circuits in the Ohtsuchi Broadcasting Station at the end of September.

Soon after this, BHN will build a new broadcasting branch studio on a hill to work as an alternative station to replace the main station at a time of emergency and could continue the broadcasting works.

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.
