Abstract
Two difficult tedhnical problems in underground radio communications, i.e. weak signal reception and counter lightning pulses interference are described, and ways to solve these problems are proposed . The design scheme of the telegraph terminal used for weak signal reception and counter lightning pulses interference is exhaustively studied. The performances of this terminal are analyzed, and results of laboratory measure and field tests are also given.
