KHF1050 PG R1 4/29/03 3:14 PM Page 1 KHF 1050 (PRIMUS HF 1050) SYSTEM DESCRIPTION The KHF 1050 System (also known as the Primus HF 1050 System) is a solid-state high frequency (HF) single sideband (SSB) transceiver system providing voice and data communication. Data communication is through an external modem. This publication describes the operation of the KHF 1050 HF Communication System using the PS440 Control Display Unit (CDU).

KHF1050 PG R1 4/29/03 3:14 PM Page 14 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. Arrangements can be made with ARINC by calling 1-800-633-6882 in the United States.
KHF1050 PG R1 4/29/03 3:14 PM Page 15 APPENDIX A CHARACTERISTICS OF HF SINGLE SIDEBAND COMMUNICATIONS HF SSB COMMUNICATIONS High frequency single side band communications achieve reliable long range transmission and reception over distances of thousands of miles. The primary reason is due to skywave propagation which allows HF radio waves which are beamed toward outer space to be reflected back toward the earth’s surface by the ionosphere.
KHF1050 PG R1 4/29/03 3:14 PM Page 16 SKYWAVE PROPAGATION - WHICH FREQUENCY TO USE? As mentioned earlier, HF’s primary method of travel or propagation is via skywaves which are radio waves that start out radiating into space and are reflected off the ionosphere back to the earth’s surface. This reflecting of signals makes communications possible over very long distancesunder ideal conditions, more than 4,000 miles and typically in excess of 2,000 miles-possible.
KHF1050 PG R1 4/29/03 3:14 PM Page 17 This rule of thumb can be explained by a mirror analogy. It is the electrically charged particles in the ionosphere which reflect or bend radio waves back toward earth like a mirror reflects light. Sunlight induces ionization and increases the density of these particles in the ionosphere during the day. The mirror becomes thicker and it reflects higher frequencies better.
KHF1050 PG R1 4/29/03 3:14 PM Page 18 You should also be aware of the possibility that you or the ground station you are calling may be in a quiet zone. The linear distance from the point of transmission to the point where the skywave returns to earth is called the skip distance. There may be a quiet zone between the end of the ground wave and the return of the skywave. No communication can take place in this area.
KHF1050 PG R1 4/29/03 3:14 PM Page 19 One feature that will be particularly useful when a trial and error method is used to find an HF frequency which is working well. This is the system’s capability to be programmed by the pilot with 100 channels using the PS440 Control Display Unit. Rather than having to select the four to six digits each time you want to try another frequency, you can preprogram the frequencies you need to contact a particular ground station.

KHF1050 PG R1 4/29/03 3:14 PM Page 21 WHY SINGLE SIDEBAND IS IMPORTANT IN HF COMMUNICATIONS As mentioned earlier, there are two characteristics of HF SSB communications which allow long range capability. Skywave propagation has been discussed in detail. The other characteristic is a transmission process known as single sideband. Single sideband (SSB) high frequency (HF) communications was developed in the early 1950’s as a means of increasing the effective range of HF signals.
KHF1050 PG R1 4/29/03 3:14 PM Page 22 NOTE: Lower sideband isn’t normally used in the aviation services. During installation of the KHF 1050 system, LSB may be enabled for use in regions or applications where its use authorized. SINGLE SIDEBAND (SSB) fc = carrier frequency fm = modulating frequency (voice) fc-fm LSB fc fc+fm USB Figure 3A - Single Sideband The result is that an SSB system has the effective transmit power of AM units having many more times the transmitter power.
