Abstract: Data obtained by systematic monitoring of anomalous long-distance TV signals at Delhi during May 1979-April 1981 have been analysed. An attempt has been made to identify various modes of propagation responsible for these signals. It has been observed that the percentage of TV receptions is higher than expected from known natural modes via tropospheric and ionospheric paths. It has been suggested that these unexplained TV signals are due to propagation via artificially modified ionosphere caused by high power, high frequency broadcast transmitters operating in the neighbourhood.
