Reception of B.B.C. television sound transmissions on 41.5 Mc/s at halley bay, antarctica

The B.B.C. television sound transmissions from London were monitored at Halley Bay, Antarctica, on 130 days between April and October 1958. The observations show that a large part of the interceptions can be ascribed to normal F layer propagation. In some months propagation was better than expected and this may have been due to the presence of abnormally long hops, though the possibility of some contribution from Es modes cannot be eliminated. Disturbance of the F layer is correlated with absence of signals.
