75.0 MHz is Aircraft Navigation Marker Beacon. This is near airports on the ILS (Instrument Landing System) course. Three lights are in the cockpit (Purple, Amber, White): Purple - Outer Marker, Intercept Point, 4 to 7 Miles downrange Two 400 Hz Dashes Per Second. Amber - Middle Marker, Cat I Decision Height, 3500 Feet downrange, 1300 Hz Dot and Dashes 95 times a minute. White - Inner Marker, Cat II Decision Height, 3000 Feet downrange, Six 3000 Hz Dots Per Seco nd. TACAN has 126 X and 126 Y channels. Normally only X channels are used, unless crowded. TACAN frequencies are tied to VOR frequencies. (Note: there are more TACAN frequencies than VOR frequencies, some are blanked around the ATCRBS Beacon frequencies, and others are for expansion and military use). Pulse widths are 3.5 us. Aircraft sounds like a Top Fuel Dragster or Funny Car when searching for lock-on. There are currently five interrogation modes in use: Mode 1, 2 pulses spaced 3 microseconds [Military] Mode 2, 2 pulses spaced 5 microseconds [Military] Mode 3/A, 2 pulses spaced 8 microseconds [Military/Civilian] Mode 4, encrypted, IFF [Military] Mode C, 2 pulses spaced 21 microseconds [Military/Civilian] A third pulse is also included in all modes (except 4) at 2 microseconds from the first. This is the sidelobe pulse. if it's within @6 dB of the first pulse (or greater) the transponder doesn't reply (as it has detected an antenna sidelobe). Pulse widths are .8 microseconds. The reply is two framing pulses spaced 20.3 us apart, with 13 code pulses (0000 - 7777 Octal) and an X pulse at the center which is not used anymore). A fourth pulse (called SPI pulse (Special Position Identifier) is used to identify your position when asked by a controller to "Squawk Ident", it is 4.35 us after the last framing pulse and lasts for 20 sec (about 2 scans of a long range radar). Pulse widths are .45 microseconds. COTHERN - Customs Over The Horizon Enforcement Network
