SEISMIC ACCESSORIES PASI RADIO TRIGGER www.pasigeophysics.com The new PASI RADIO TRIGGER is a versatile and easy to use instrument designed for triggering a seismic acquisition via radio, by transmitting in the European band 869.4 ÷ 869.65 MHz (free license with no goverment taxes). If you are based or you operate outside Europe, please verify if it is possible to use this band also in your country. PASI RADIO TRIGGER is particularly useful as an alternative to long trigger lead-in cables: the basic system consists of a transmitter Tx (to be connected to the hammer switch) and by a receiver Rx (to be connected to the seismograph). Like any radio Tx-Rx device, the radio trigger and its antenna must be properly positioned in the field to assure best performance (e.g. open space without obstacles, “visibilty” between Tx and Rx, etc.).
