内容記述 | In order to add more non-attended field stations to the long range tele-recording seismograph system for local shock observations, two sets of UHF multi-channel radio tele-recording seismographs were designed and constructed. As the allotment of radio frequencies in this country is now very rigid, we cannot easily increase the number of stations equipped with radio tele-recording seismographs (RTS), assigning many separate frequencies to them all, as was done in Johannesbourg, South Africa. And, accordingly, we must devise the means to set up the RTS equipments, without increasing the frequencies used for transmission. In the new equipment, RTS-II, we adopted 419.8 MHz P.M. radio waves for both sets, and separate receiving at base was executed by way of radio wave polarization, which was accomplished by using horizontal and vertical YAGI antennae for transmitters and receivers. The directional character of the aerials is also to be utilized to diminish the frequency allotment, setting the field stations in azimuthal positions from the receiving base. | |||||
