IN a paper by Kent1 it was stated that irregular fading of satellite transmissions on 40 Mc./s. from Sputnik 1 did not occur when the satellite was south of 50° N., and indeed was of very small amplitude on the average when the magnetic inclination at the sub-satellite point was less than 68°, the value at the observing station near Cambridge. Mawdsley2 has suggested that this might be due not to the absence of irregularities to the south of Cambridge but to the southerly irregularities being incorrectly oriented to give appreciable power scattering to the receiver.
