Transmission Loss for Ionospheric Propagation Above the Standard MUF

Radio Science, 1966
Transmission loss for ionospheric propagation over a 4000‐km path from Maryland to Southern California has been measured experimentally at several frequencies in the HF band. The observed losses were in close agreement with those predicted at all frequencies near and below the st~dard maximum usable frequency (MUF).

Propagation Above the Classical MUF on Long Distance Circuits

IETE Journal of Research, 1964
ABSTRACTSometime back, All India Radio used to broadcast to U.K. between 1300 and 1400 IST (IST-GMT+ 5½ hours). During the years 1953 and 1954, when the sunspot activity was at its minimum, the optimum bands worked out to be quite low. In actual practice, bands higher than OWP and even MUF for F2-layer transmission were found to provide reliable ...
