  17. (“++” series) to requisition DLR items.
    5_
  18. Coast Guard units shall document and package unserviceable DLR items within +++hours of receipt of replacement item
    48
  19. Priority +++ items will be shipped by certified mail
    13
  20. The ELC will send the unit a message at the +++ day stating that item is overdue and due back in +++ days to avoid billing.
    45th, 30

  22. Three types of EMI:
    Man-made
  23. Natural
  24. Inherent
  25. +++++ interference impedes the reliable and efficient use of electrical and electronic equipment.
    Man-made
  26. +++++ interference consists of a single frequency or a narrow band of frequencies that occupies little space in the total receiver passband.
    Narrowband
  27. +++++interference occupies a relatively large part of the radio frequency spectrum.
    Broadband
  28. ++++++ interference, such as that caused by electrical storms, snowstorms, rain particles, or interstellar radiation, is referred to as atmospheric noise or static.
    Natural
  29. Interference is transferred from an interfering source to the affected equipment by two general methods:
  30. • Conduction
  31. • Radiation
  32. +++++ is any interfering signal transferred through space by an electromagnetic field
    Radiated EMI
  33. +++++ are recognized by their distribution across a wide portion of the tuning range of the affected receiver
    Broadband emissions
  34. Military specifications require that the second harmonic level be at least ++db below the fundamental
    60
  35. Third and higher order harmonics must be at least ++ db below the fundamental
    80
  36. ++++++ cause emissions at radio frequencies which are neither harmonics of the fundamental nor inter-modulation product frequencies.
    Parasitic oscillations
  37. ++++++ occur when a circuit is self-excited and goes into oscillation at a frequency other than the desired one.
    Parasitic emissions
  38. _______is the transfer of modulation from one carrier to another
    Cross modulation
  39. +++++ is the generation of numerous new frequencies from two or more original signals.
    Intermodulation
  40. ++++++ occurs when the center frequency, or carrier of an undesired signal, falls in any portion of the passband of another receiver.
    Co-channel interference
  41. +++++++ occurs when a strong unwanted signal penetrates the input filter circuits and encounters a nonlinear element such as the mixer of an overloaded RF amplifier stage.
    Nonlinear intrusion
  42. ++++++ occurs when internally or externally stressed metals are exposed to a corrosive environment.
    Stress corrosion
  43. Signals, created by nonlinear junctions in the ship structures, are commonly called the +++++
    rusty bolt effect
  44. Arcing can occur inside of waveguide causing a high voltage standing-wave ratio (VSWR) due to:
  45. • Foreign objects (including moisture) in the waveguide
  46. • Corroded or flaked-off coating
  47. • A sharp bend in the waveguide run
  48. Arcing may result when a radar rotary joint is:
  49. • Dirty
  50. • Worn
  51. • Misaligned
  52. Interference between radars usually appears as a series of moving dots, or ++++++on the CRT
    running rabbits
  53. Two general techniques for bonding:
    direct and indirect
  54. ++++ bonding is achieved by direct metal-to-metal contact between two metal items through the process of welding or brazing.
    Direct
  55. ++++++ bonding is achieved by the use of a bonding jumper or bolts between two metal items.
    Indirect
  56. Three major types of cables
