Air Shower Radio Emission with Energy E${}_0$$\ge$10${}^{19}$ eV by Yakutsk Array Data

The paper presents short technical description of Yakutsk Radio Array and some preliminary results obtained from measurements of radio emission at 32 MHz frequency induced by air shower particles with energy {\epsilon}$\ge$1$\cdot$10${}^{19}$ eV. The data obtained at Yakutsk array in 1987-1989 (first set of measurements) and 2009-2014 (new set of measurements). For the first time, at Yakutsk array radio emission from air shower with energy

10${}^{19}$ eV was registered including the shower with highest energy ever registered at Yakutsk array with energy $\sim$2$\cdot$10${}^{20}$ eV.
