Introduction INTRODUCTION KHF 950/990 COMMUNICATIONS TRANSCEIVER High frequency (HF) communications made easy, that’s what the King KHF 950/990 HF SSB Transceiver is all about. The KHF 950/990 is a compact, lightweight system to provide an extensive range of operator benefits. It is designed with international flight operations in mind to provide superior long range communications.
Introduction High frequency radio opens a world of communication possibilities to the pilot and his passengers, including long range contact with air traffic control agencies over thousands of miles away, time and frequency standard broadcasts, Omega navigation station status reports, weather and marine storm warnings, radiotelephone service for personal messages and ARINC operational control services for messages relating to flying operations.

Description wave containing the intelligence to be communicated. Both of these make HF radio highly useful to aircraft flying over water or desolate land areas when they are out of reach of VHF communications which are limited to line of sight transmissions.
Description 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 over very long distances-under ideal conditions more than 4,000 miles and typically in excess of 2,000 miles-possible.
Description phere. One of the best things the pilot can do to assure the best possible HF communications, based on existing HF propagation conditions, is to select the proper frequency. A good rule of thumb for the time of day is that the higher frequencies are best during daylight (10 to 29.9999 MHz) and lower frequencies work best at night (2 to 10 Mhz). This rule of thumb can be explained by a mirror analogy.
Description quencies are likely to be the most effective. The closer a frequency is to the MUF, the better it is likely to be. FR AC TIO N The effect of solar disturbances including solar flares and magnetic storms is to change the particle density in the ionosphere. Therefore, the “window” of useable frequencies may begin to close, with radio waves of frequencies in the lower range dropping out first as they are absorbed by the ionosphere.
Description There are even times when solar disturbances improve the usability of higher frequencies in the HF band, particularly in equatorial regions. Another phenomenon which occurs during solar disturbances may allow you to communicate with a station even though the “window” is closed. This is known as scatter propagation, in which a radio wave is broken up in the ionosphere and scatters in various directions.

Description 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.
Description SINGLE SIDEBAND OPERATION By electronically eliminating the carrier wave and one sideband, a single sideband transmitter manages to pack all of its power in transmitting the remaining single sideband. (Figure 1-3). Either the upper sideband (USB) or the lower sideband (LSB) can be used since each sideband contains all the required intelligence. However, from a practical standpoint the USB is used almost exclusively in airborne HF SSB operations and the LSB may be disabled.
Description SIMPLEX AND SEMI-DUPLEX OPERATION The KHF 950/990 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. Semi-duplex operation means that messages are transmitted on one frequency and received on another.
Description SCANNING - All available stations continuously and rapidly scan their receivers through their channels, seeking ALE calls. At any time, a calling station may slowly scan its transmitter through their channels, calling on each one, until answered on a channel that supports contact. This function enables the selection of a channel that successfully supports contact, despite variations in propagation, occupancy, and other traditional HF challenges.
Description ALE relieves you of the burden of trying to manually detect and compensate for random changes in the ionosphere and of searching for a good channel to use. It lets you concentrate on the message to be sent. During the time when no call is present, the radio is squelched to reduce noise in the cockpit. After a call is received, a sound like a phone ringing is heard, the radio un-squelches, and you can commence a normal HF communication.

Operation SECTION III OPERATING THE KHF 950/990 KHF 950/990 GENERAL OPERATING INFORMATION PREFLIGHT INSPECTION During preflight walk around inspection, it’s important to check the HF antenna for structural integrity. Long wire antennas may be used with the KHF 950, and these can be damaged by ice accumulation in flight or broken by improper aircraft ground handling or fueling operations.
Operation CAUTION: When performing a ` radio check on the ground, make certain that all personnel are clear of the HF antenna before transmitting. SERIOUS RF BURNS CAN RESULT FROM DIRECT CONTACT WITH THE ANTENNA OR ANTENNA TERMINAL WHEN THE SYSTEM IS TRANSMITTING. ANTENNA TUNING When using a KCU 1051 control display unit, the antenna coupler tune information is stored in non-volatile memory. This means that retunes are required only when new frequencies are entered into the channel non-volatile memory.
Operation Using the KCU 951 or KFS 594, if the system detects a fault during transmission or during the tuning of the antenna coupler, the frequency digits on the display begin to flash. Simply key the mic and the automatic antenna coupler begins a new tuning cycle to clear the fault. TUNING FAULTS If the antenna coupler is unable to find an acceptable frequency/antenna match, the fault indication continues at the end of the tuning cycle.

For items that are longer than 16 characters, left and right arrows are used to indicate that there is more data that can be displayed using the CRSR knob when the cursor is in character mode. The arrows can point up or down for a list of items. The down arrow means this is the top of the list, and the up arrow is used for the bottom of the list.
Operation In manual operation mode four types of channels are available: • 1 frequency agile • 100 programmable manual channels • 100 ALE channels • 245 fixed ITU channels FREQUENCY AGILE The frequency agile channel mode provides the operator with a scratch-pad area to make frequency and modulation changes without modifying stored data. This mode is indicated by five underscores “ _ _ _ _ _ “ in the channel type field and a channel number of zero (0).
Operation INITIAL MANUAL CHANNEL The initial channel used when changing from ALE to MAN mode depends on the current ALE state. If the ALE state is linked, then the linked ALE channel is used, otherwise the last channel selected by the operator in manual mode is used. MANUAL CHANNEL ENTRY Changes made to the 100 manual channels are stored in nonvolatile memory. The frequency, modulation type, and communication type are programmable.

The three sub-pages are: • Interval Set intervals • Enables Set Enables • Bright Adjust display brightness (performed on installation only) The operator moves between these sub-pages by placing the operator on the sub-page field and turning the VAR knob to select another sub-page. INTERVAL The Interval Page is a Program Operation Sub-Page.
Operation IIIIIIIII * Interval type XX * Interval UUU ActvLim, ScnRate, Sound, CallTime unit of measure * Cursorable fields Activity Limit Time-Out Period (ActvLim) ActvLm stands for activity limit. The activity limit is the amount of inactive time, in minutes, allowed while linked before a radio automatically hangs-up and returns to scan. The inactive timer runs whenever the radio is linked and in receive. The timer is reset each time the microphone key button is released.
Operation cycle time of any radio that will be called. The scan cycle time is the length of time a radio takes to go completely through its scan list. The scan cycle time is calculated by dividing the number of channels on the scan list by the scan rate. Example:15 channels at 5 Hz scan rate, results in a 3 second scan time ( 15 / 5 = 3). ENABLES The Enables Page is a Program Operation Sub-Page. This page works in a similar manner to the interval page.
Operation Enable Automatic Sounding (NORMALLY DISABLED) (AutoSound) When Sounding is enabled, the system will sound at the time interval set in the sound interval. Sounding is a one direction non interactive broadcast of a radios self address. Other radios receive the sound and use it to measure the quality of the received signal. Enable LQA in Call (NORMALLY ENABLED) (LQA in Call) When LQA is enabled, Link Quality Analysis data will be exchanged with each call.
Operation Enable Numeric Digit Roll Over (NORMALLY ENABLED) (Roll Over) When enabled digit roll over causes numerical entries to ‘roll over’ from minimum to maximum and maximum to minimum values. When digit roll over is disabled, numerical entries stop changing at the minimum and maximum values. Operation of the frequency field changes depending on the digit rollover state. When direct rollover is enabled, then changes to a frequency digit past nine carries/borrows from the next higher digit.

Operation For prestored channels Set Cursor over channel number with CRSR knob. Select channel with VAR knob. For new frequency Set Cursor over frequency with CRSR knob. Push VAR knob (push CHAR), then use the VAR and CRSR knobs to change the frequency. Push ENT when finished. Begin normal HF communication.
Operation When the KHF 950/990 is first turned on with the KCU 951, and has warmed up the system “wakes up” and display the last frequency transmitted if the FREQ/CHAN button is “out” (direct tuning). If the FREQ/CHAN button is “in” (channelized operation), the system “wakes up” displaying the channel number last used. In either case, all preset channels are stored in nonvolatile memory and can be recalled after the system is turned on.
Operation band suppressed carrier mode of emission is not used to transmit SELCAL signals, therefore ARINC HF ground station transmitters switch to the AM mode when transmitting SELCAL signals. The KTR 953-01 is designed to detect SELCAL signals transmitted in the AM mode even though the mode selector is in a single sideband mode. CLARIFIER The CLARIFIER knob is unique to SSB communications and is not used when operating in the AM mode.
Operation The MODE button is used to select transmission and reception mode. Momentary depression of the MODE button cycles the KHF 950/990 from upper sideband (USB) to lower sideband (LSB) to AM. The single sideband reduced carrier (A3A) mode of operation is normally disabled at time of installation. However, if it has been enabled, this mode is annunciated with both “AM” and “USB” simultaneously displayed.
Operation preset channels by the pilot at any time, on the ground or in flight, to increase the convenience of frequency selection when HF use is required. NOTE: The use of the concentric frequency/channel control knobs, the PGM (Program) switch, and the STO (Store) switch are explained in the following sections. DIRECT TUNING A FREQUENCY In direct tune operation, the pilot may select directly any of 280,000 frequencies in the range of 2.0 to 29.9999 MHz. The frequencies progress in 100 Hz steps.
Operation NOTE: Although normally disabled, the KCU 951 also has the capability of being internally enabled by aircraft wiring so that dial-like “borrow/carry” tuning will occur. For example, when so enabled, if two existing frequency digits are 89 with the “cursor” on the 9, a further clockwise rotation of the knob will change the digits to 90 rather than to 80, as is normally accomplished.

Use a pencil or similar pointed object to push the PGM (program) switch “in”. (This switch is located on the lower right of the KCU 951 Control Display Unit.
Operation 3. Receive only. The pilot programs a frequency in receive, but leaves the transmit portion of the preset channel blank. The transmitter is locked out and can’t be used when a channel has been programmed for receive only operation. The pilot also assigns an operating mode (USB, LSB or AM). (Used to listen to weather, time, Omega status, frequency standard and geophysical alert broadcasts.) To gain access to channelized operation of the KHF 950/990, make sure the FREQ/CHAN button is “in”.
Operation 1. Stow the “cursor” if a frequency digit is flashing. The cursor is stowed by twisting the larger concentric knob until no frequency digit is flashing. With the cursor stowed in the program mode, the smaller inner knob is now used to select a channel number to be programmed. 2. Use the smaller inner concentric knob to select the channel number you wish to program. Simply twist the smaller knob until the desired channel number appears on the right side of the display. 3.

Services SECTION VIII TIME & FREQUENCY STANDARD BROADCAST STATIONS DESCRIPTION OF SERVICES A worldwide network of high frequency radio stations has been established to broadcast time and frequency signals and other information on HF frequencies. Although this information is broadcast for a wide variety of users, it can be very useful to pilots. WWV AND WWVH In the United States, two of these stations are operated by the National Institute of Standard Technology (NIST).

Services be considered generally equivalent to the more well known “Greenwich Mean Time” (GMT). The most frequent sounds heard on WWV and WWVH are the pulses that mark the seconds of each minute, except for the 29th and 59th seconds pulses which are omitted completely. GEOPHYSICAL ALERTS ON WWV WWV broadcasts geophysical alert announcements at 18 minutes past each hour. (A similar recorded message can be heard by calling commercial number (303) 497-3235.
Services During periods of geomagnetic disturbances, the window of usable frequencies is likely to shift rapidly. As the K index goes up and geomagnetic disturbance increases, HF propagation is deteriorating because the density of electrically charged particles in the ionosphere is being reduced. The fewer of these particles there are, the less effective the ionosphere becomes as a mirror reflecting HF radio waves back toward earth.
Services siderable difficulty getting through. With few exceptions, the higher the solar flux and the lower the A and K index values (level of geomagnetic disturbance), the better HF propagation conditions should be and vice-versa. See Appendix A for more information on the format of geophysical alert broadcasts and a glossary of related terms. Incidentally, prior to September 30, 1976, radio propagation forecasts useful to an HF user were broadcast on WWV.
Services If there are no warnings in the designated areas, the broadcasts will so indicate. The ocean areas involved are those for which the U.S. has warning responsibility under international agreement. The storm warnings are originated by the National Weather Service (NWS) at 0500, 1100, 1700 and 2300 UTC for WWV and 0000, 0600, 1200 and 1800 for WWVH. These broadcasts are updated effective with the next scheduled announcement following the time of issue.
Services TIME AND FREQUENCY STANDARD SERVICES WORLDWIDE WWV and WWVH are two of the stations broadcasting time and frequency standard signals around the world.

Services SECTION IX VOLMETS VOLMET broadcasts are routine reports of meteorological information for aircraft in flight. These broadcasts are made on VHF as well as HF radio. The VHF reports contain current aerodrome weather reports, with trend information where available. The current observation usually includes temperature, dew point and altimeter setting. The HF reports include the current information as well as aerodrome forecasts.
Services This way you don’t have to page through the list of all ground stations searching for a reference to the airport for which you want a forecast. Other agencies around the world like the FAA also broadcast VOLMETS. These can be very useful when flying over water. The New York station, for example, may be received as you are flying over the North Atlantic and allow you to begin planning your arrival and alternate intentions based on forecast weather for the airports you are planning to use.
