Radio-Navigational AidsAN/MRN-9RADIO TRANSMITTING SETFUNCTIONAL DESCRIPTIONThe AN/MlW-9 is an unattended, remotelycontrolled ground station designed toprovideaircraft with indication of bearing with referencetothestation and track guidance betweenthe station and any point within theline of sight without limitation as to azimuth.Transmitting on an asaigned carrier inthe 112 to 118 mc band, the AN/m-9 radiatestwo fields. One field. rotating 30 times persec., develops in the receiver a 30 cyclesignal withaphase that varies directly withazimuthal position around the station. Theother field carriers a 30 cycle referencesignal whichis received in the same phase atall points in azimuth. The difference inphase between the received signals indicatesthe position of the aircraft in azimuth.Course orientation is under control of thepilot, a theoretically infinite number ofradial visual courses being open to him.A 1020 cps code identification and a voiceidentification signel modulate the carriercontinuously except when emergency or otherinformation is being broadcast over the ststion.To permit periodic inspection and maintenancewhile maintaining continuous yearroundservice. duplicate transmitting equipmentis provided for alternate operation.A monitoring system checks the station outputcontinuously and automaticslly. In theevent of transmitter trouble it actuateswarning alarms at the remote control location.Remote controiisaccom~lished by meansof a telephone-type dial via a single paircontrol line from a position up to 30 milesfrom the range.

Directionfinding information is displayed onthe screen of a five inch cathode-ray tubeand the associated bearing is readable fromconcentric azimuth rings. In addition, panoramictype (frequency scanning) operation,not simultaneous with the Direction Findingfunction, enables the operator to visuallymonitor a band of frequencies.

As many as one hundred aircraftmay simultaneously obtain navigational informationin conjunction with a single installationof Radio Set AN/SRN-6.Radio Set AN/SRN-6iscapable of receivingon any one of 126 frequencies in the rangeof 1025 to 1150 megacycles. The set cantransmit on any one of 126 frequencies inthe ranges of 962 to 1024 megacycles and1151 to 1213 megacycles. Two types of antennaare available for use. Each antenna canoperate on 63 channels, either in a low bandof frequencies or in a high band of frequencies.Low band installations transmit atfrequencies between 962 and 1024 megacyclesand receive st frequencies between 1025 and1087 megacycles. High band installations,transmit at frequencies between 1151 and 1213megacycles and receive at frequencies between1088 and 1150 megacycles. Two frequenciesare used in each channel, one forreceiving and one for transmitting. In lowband installations, the frequency used forreceiving is 63 megacycles above the frequencyused for transmitting in the samechannel. In high band installations, thereceiving frequency is 63 megacycles belowthe transmitting frequency.This set em~loys . . a SAL-89 Klystron in thetransmitter output stage, but is designedfor shipboard installation.

The Radio frequency energy radiatedby these transmitters cover a large area atthe earth's surface. The radiation patternmay be plotted on a geographical map as agrid composed of interesting hyperbolic lines.Any ship, or other carrier, using phasemeasuringequipment such as Radio ReceivingSet AN/SRN.7 can navigate with a high degreeof accuracy within an trea covered by theLORAC grid. Fixing a posltion at the receivingset consists only in reading two positionindicator dials and in locating these readingsas map coordinates.
