    PRS F Antenna Coupler Pressure Failure (transmitter power has been reduced to 50 Watts. The antenna coupler requires service.) SQUELCH The KHF 1050 system offers four types of squelch with corresponding values as follows: SBH - (Syllabic Squelch High). This is the default squelch and is usually best for normal voice communications.
  • Page 8: Direct Tuning A Frequency

    Table 1 summarizes the typical propagation distances of various fre- quencies. In direct tune operation, the pilot may select directly any of 280,000 fre- quencies in the range of 2.0 to 29.999 or 29.9999 MHz depending on installation configuration.

    .1 MHz increments. The inner knob changes the frequency in .001 MHz (1 KHz) increments or .0001 MHz (100 Hz) increments, depending on the configura- Figure 5 tion selected when the system was installed. Revision 0 Mar/2003 KHF 1050/PS440 Pilot’s Guide...
  • Page 10: Semi-Duplex Direct Tuning

    After the new frequency is selected, press the push-to-talk to tune the antenna coupler. NOTE: The KHF 1050 stores the antenna coupler tune information for previously tuned frequencies. If the antenna coupler was previously tuned for the current frequency (or nearby frequency) the antenna cou- pler may not need to be tuned and transmission may begin immediately.

  • Page 12: Channel Operation And Programming

    Emergency channels typically use simplex operation. However channels 2 - 6 can be programmed for semi-duplex operation. The emergency channels are programmed at the factory according to Table 2. Only channels 2 - 6 may be changed. Revision 0 Mar/2003 KHF 1050/PS440 Pilot’s Guide...

  • Page 16: Maritime Radiotelephone Network Channel Operation

    All 246 ITU public correspondence channels in the maritime radiotele- phone network are programmed permanently in the electronic memory of the KHF 1050 System. These channels may be used by aircraft to make telephone calls through the High-Seas-Operator Network. Refer to Appendix B for channels and frequencies.

    4. Select any other function to exit. Figure 13 DATA COMMUNICATIONS The KHF 1050 System will transmit and receive data, such as fax trans- missions, etc. Data communication requires an external modem be installed with the system. Before transmitting or receiving data, select the appropriate Mode (USB D, LSB D or possibly AM) as previously discussed in Mode Selection.
  • Page 18: Aviation Services Available To Hf Users

    AVIATION SERVICES AVAILABLE TO HF USERS In addition to using the KHF 1050 for air traffic control functions, HF users can also take advantage of other HF services. ARINC AIR/GROUND INTERNATIONAL RADIO SERVICES This service can be used to coordinate flight and ground activities, advise dispatch of events, provide radio checks and a variety of other related services.
  • Page 19: Characteristics Of Hf Ssb Communications

    Air Traffic Control facilities generally travel line-of-sight range and are not greatly affected by atmospheric dis- turbances. As will be discussed next, HF has its own characteristics which allow long range communications to take place. Revision 0 Mar/2003 KHF 1050/PS440 Pilot’s Guide...
  • Page 20: Skywave Propagation - Which Frequency To Use

    The net result of all these factors is that because the ionospheric and atmospheric conditions are constantly changing, HF communications can vary in quality and strength. The signal received on the KHF 1050 may be accompanied by a considerable amount of static from atmos-...

  • Page 22 HF communications will typically operate on several different frequencies within the HF band. The pilot is then able to choose the optimum communication frequency for the exist- ing ionospheric conditions. Revision 0 Mar/2003 KHF 1050/PS440 Pilot’s Guide...

  • Page 25: Why Single Sideband Is Important In Hf Communications

    AM since it allows simpler receivers. NOTE: The use of lower sideband isn’t normally authorized for airborne HF use. It is normally used in the KHF 1050, but can be selected for those who are authorized to use it.
  • Page 26: Single Sideband Operation

    SIMPLEX AND SEMI-DUPLEX OPERATION The KHF 1050 is capable of both simplex and semi-duplex operation. Simplex operation means that communication signals are transmitted and received on the same frequency. Simplex operations are used when communicating with Air Traffic Control (ATC), for example.
