I remember something like 900 Hz rotation...is that still correct?
900 Hz rotation? I don’t know what that is.
My TACAN system uses gaussian pulses of various rep rates and spacings on an RF carrier of between 960 and 1215 MHz.
IFF IS 1030/1090 MHz rectangular pulses of various widths and spacings.
SLS uses 1030/1090 MHz with rectangular pulses of varying amplitudes, spacings and widths relative to each other.
