The paper describes the techniques and method of registration of air showerradio emission at the Yakutsk array of extensive air showers at a frequency of32 MHz. At this stage, emission registration involves two set of antennas, thedistance between them is 500m. One set involves 8 antennas, second - 4antennas. The antennas are perpendicularly crossed dipoles with radiationpattern North South,West East and raised 1.5 m above the ground. Each set ofantennas connected to an industrial PC. The registration requires one of twotriggers. First trigger are generated by scintillation detectors of Yakutskarray. Scintillation detectors cover area of 12 km^2 and registers air showerswith energy more than 10^17 eV. The second trigger is generated by SmallCherenkov Array that covers area of 1 km^2 and registers air showers withenergy 10^15 - 5*10^17 eV. Small Cherenkov Array is part of Yakutsk array andinvolve Cherenkov detectors located at a distance of 50, 100, 250 m. Forfurther selection we are using an additional criterion the radio pulse must belocalized in the area corresponding to the delay time on first and secondtriggers. In addition, descriptions of the algorithm and the flowcharts of theprogram for the air shower selection and further analysis are given. Thismethod registers EAS radio emission with energy 10^16 - 10^19 eV. With theabsolute calibration, the amplitudes of all antennas converted to a singlevalue. Air shower radio emission dependences from zenith angle and showerenergy are plotted.
