  • Page 11: Note On Cable Routing

    NPX136D Series Panel Mount P25 VHF Transceiver SM68 Installation and Operation Manual 2.4.1 Note on Cable Routing Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any logic, audio, or DC power lines from this unit with 400 Hz synchro wiring or AC power lines. Do not position this unit next to any device with a strong alternating magnetic field such as an inverter or significant interference to operation will result.

  • Page 12: Antennas

    NPX136D Series Panel Mount P25 VHF Transceiver SM68 Installation and Operation Manual recommended that VHF FM coax runs be widely separated, or be made using triaxial cable, with the outer shield bonded to the airframe at one end only (transceiver end). In communication-intensive applications, poor cable routing and shielding may drastically compromise over-all system performance.

  • Page 13: Mechanical Mounting

    NPX136D Series Panel Mount P25 VHF Transceiver SM68 Installation and Operation Manual Avoid antenna locations that will become fouled with oil, water, fuel or dirt, as this will degrade performance. Roof mounts (in close proximity to rotor blades) are permissible.

  • Page 18 INSTALLATION APPROVAL TEST PROCEDURE NAT Part #: NPX136D Description: Panel Mount Radio Document #: NPX136D\634-0 Rev: 1.00 Post Installation EMI Test The purpose of this test is to identify any interference that the NPX136D may cause with existing aircraft systems.
  • Page 19 NPX136D Installation Approval Test Procedure Results If the installed system passes all of the applicable EMI tests, then no further action is required. If interference is observed, then the interference must be assessed against the appropriate standards of airworthiness for the system in question. For example: it is permissible for a VFR certified GPS to lose navigation capability while the NPX136D is transmitting, providing that it recovers properly and promptly, but it is not permissible for an IFR Approach certified GPS to be affected in the same way.
  • Page 20 NPX136D Installation Approval Test Procedure Determine if the image frequency for the VHF Comm falls within the range of the NPX136D unit. If so, select a set of frequencies that will cause the NPX136D to be set as close as possible to the image frequency. Any one of the many possible sets will suffice.
  • Page 21 NPX136D Installation Approval Test Procedure Determine if the image frequency for the VOR/ILS Nav falls within the range of the NPX136D unit. If so, select two sets of frequencies that will cause the NPX136D to be set as close as possible to the image frequency. Choose one set in the localizer frequency range, and one in the VOR frequency range.
