Knickebein

Eckersley is mentioned in the television documentary ‘The Secret War - Battle of the Beams’ as denying that the suspected German Knickebein aircraft guidance beam, on 31 Megacycles, could ‘bend’ sufficiently, i.e. be refracted by the ionosphere, to pin-point a target in England.

R.V. Jones asserts that Eckersley’s own research showed that a 31 M/C signal would reach the UK from Central Germany. Eckersley then said that was only his hypothesis. So, did Jones mis-read the Eckersley research document?

In any case, Knickebein worked. What was the sunspot index at the time? Perhaps that helped propagation at that frequency for the duration. The sunspot index was at a maximum during the Citizen Band Radio Service craze during the late 1970s and early 1980s. Persons using low-powered transceivers on 27 MHz could communicate globally at that time. The ham radio community had a similar field day on the 10 meter band during the same period, for the same reason. 124.150.81.3 (talk) 20:52, 16 January 2024 (UTC)[reply]
