How many frequencies does the sincgars use for communication

NOTE: Anytime the operator moves a switch to a setting with a box around the letters, the knob must first be pulled before it is turned. This feature ensures that the knob is not accidentally moved to another position.

Receiver-Transmitter RT - most of the controls that the operator will use are placed on the face of the RT see figure 2. This position is used when communicating in the SC mode with radios having a different squelch system.

Figure 2. Face of Receiver Transmitter. The RTs battery hub battery will maintain the memory of the radio including frequencies and times. This position is used as an alternative to OFF when the operator is concerned about conserving power during non-operating periods, but wants to retain all of the data loaded for operations occurring in the near future same day.

TST test - conducts a self-test of its internal circuits. At the completion of the test, the radio will display results. Whenever the radio is put into operation, the operator should conduct a self-test.

In order to load any of this information into the radio for use, the operator must ensure that LD is positioned so the radio will receive the input. OFF - turns off all of the power to the RT.

When the radio is in the OFF position for more than five seconds, the memory is completely cleared. Mode Switch - sets the receiver-transmitter mode. The mode switch has three settings that allow the operator to select the mode of operation see figure 3. Figure 3. Mode Switch. SC single channel - places the RT in the single channel mode of operation. PT plain text - placing the switch at this setting places the RT in the plain text, not a secure, mode of transmission.

CT cipher text - this setting allows the operator to use cipher, secure, transmissions when placed to this position.

Figure 4. CHAN channel Switch - selects manual , preset or cue frequencies. Operating this switch allows the operator access to any of the frequencies loaded into the channels. This switch is the means that the operator changes frequencies that are preset see figure 5.

MAN manual - selects the loaded manual frequency. The manual frequency is used during FH operations and will be discussed later. This frequency is also used in FH operations and will be discussed later.

These are the channels that may be loaded with operating frequencies or hopsets. Figure 5. Channel Switch. RF Switch - adjusts power level of transmissions. This is the switch that enables the operator to change the power output of the radio see figure 6 a. DIM Control - adjusts display brightness. The Torn. With base station antennas basically the German version of the RC and RC series vertical ground plane antennas this radio could provide impressive range for battlefield tactical purposes and communications with other similar radios as well as smaller tactical VHF AM radio sets.

Various handheld and manpack radios covering these bands have been manufactured and used in various countries. For example, to select the frequency This list applies to the United States only. Western equipment generally favors Easily acquired and widely available commercial off-the-shelf COTS communications equipment has introduced additional bands as a replacement to or in conjunction with, or as a replacement for, the standard military bands as emerging threats in areas where asymmetric warfare, guerrilla warfare and insurgency tactics are used.

In the United States, most military systems still use 50 kHz step compatible frequencies for range control cf.

Fort Hood Range Control on See the frequency bands above. Vintage military radio equipment is also used by amateur operators in the HF bands and VHF bands above 6 meters where available.

This includes the 4 meter band around 70 MHz, which is available in select countries for amateur use. With the adoption of the PRC and VRC family of radios and associated fixed and aircraft radios , armor, artillery and infantry could all communicate using the same radios, greatly improving tactical battlefield communications in time for the Vietnam War.

Modular design. Ground and airborne versions. Common Characteristics The services tailor their particular radio designs to satisfy service-unique requirements. These radios require the following common characteristics to ensure interoperability in multiple nets: a.

FH data waveform. SC FM operation: Late net entry capabilities. They have an internal module that performs the cipher functions; thus, they do not need the external KY equipment. All three versions of the airborne radio handle voice; only the data bus version RT handles data through use of a data rate adapter DRA.

Air Force. The greatest number of radios exists on amphibious ships, with the largest population on command and flag-configured ships. Marine Corps. When establishing CNR nets, commanders must consider the mission, availability, and capabilities of CNR communications equipment, electronic attack EA capabilities of adversary forces, and United States US national security policy. SC PT operations provide ease of operation while providing little or no security or protection.

FH CT communication protects both the message and the sender. SC Mode. When operating in the FH mode, two of the SC presets are reserved for the manual and cue channels.

FH Mode. In addition, users in nets sharing common hopsets, TSK, and sync time can also move from net to net by entering the appropriate net ID.
