Preventive Maintenance Preventive maintenance is the systematic care, servicing, and inspection of equipment to prevent the occurrence of

11、trouble, to reduce downtime, and to assure that the equipment is serviceable. a.Systematic Care. The procedures given in paragraphs 20.1 and 20.2 cover systematic care essential to proper upkeep and operation of the equipment. The cleaning operations (par. 20.3) should be performed once a day. If th

12、e equipment is not used daily, the cleaning operations must be performed before operation after any extended shutdown, or once a week while the equipment is kept in a standby condition. The other items must be checked before the equipment is placed in operation after a shutdown, during operation, or

13、 after it is turned off, as specified in the applicable paragraph. b.Preventive Maintenance Checks and Services. The preventive checks and services chart (par. 20.2) outlines inspections to be made each day. These checks and services are made to maintain Army equipment in a combat serviceable condit

14、ion; that is, in good operating condition. To assist operators in maintaining combat serviceability, the chart indicates what to inspect, how to inspect, and what the normal conditions are; the References column lists the paragraph or figure that contains additional information. If the defect by rem

15、edied by the operator, higher echelon maintenance or repair is required. Records of these checks and services must be made in accordance with TM 38750. 20.1. Preventive Maintenance Checks and Service Periods a.Preventive maintenance checks and services of the R-390/URR are required on a daily basis.

16、 b.Paragraph 20.2 specifies services and inspections that must be accomplished daily and under special conditions listed below for transportable and mobile installations.

The receiver provides for recep- Figure 2. Space diversity receiving system. tion of continuous wave (cw), mo

37、dulated-continuous- wave (mcw) amplitude-modulated (am.), frequency shift keyed (fsk), and single-sideband signals. b.The receiver furnishes audiofrequency (af) output power to a local loudspeaker and headset or a balanced line. An intermediate frequency (if.) output is also provided so that receive

38、d radio teletypewriter signals may be fed to other equipment for conversion into signals usable by teletypewriter equipment. 4. System Application a.Space-Diversity Receiving System. (1)Two or three receivers can be connected as a space-diversity receiving system for reception of voice signals (fig.

39、 2). This system provides sub- 3 Figure 3. Space-diversity radio teletypewriter system. Figure 4. Single-sideband radio teletypewriter system. stantially uniform audio output to a loudspeaker or headset, minimizing the effect of fading signals. (2)Rhombic or doublet antennas spaced at least 600 feet

40、 apart are connected to the two receivers. b.Space-Diversity Radio Teletypewriter System. Figure 3 shows two receivers connected in a space- diversity radio teletypewriter system. The doublet or rhombic antennas feed the incoming frequency-shift signals to the receivers. The outputs of the receivers

41、 are applied to a converter which provides diversity combining and produces direct current (dc) signals for the operation of teletypewriter equipment. c.Single-Sideband Radio Teletypewriter System. A receiver and Single Sideband Converter CV-157/URR are connected as shown in figure 4 for the recepti

42、on of single-sideband (ssb) multichannel radio teletypewriter signals occupying 12 kilocycles (kc) of radio-frequency (rf) spectrum space divided into two 6-ke sidebands, one 6-kc sideband on each side of a reduced carrier. A double-sideband signal, either am. or phase-modulated (pm), occupying up t

43、o a total of 12 kc of spectrum space also can be received. For additional information, refer to TM 11-649. 5. Technical Characteristics Frequency range .0.5 to 32 mc in 32 bands. Type of signalsA1 (cw), A2 (mcw), A3 received(voice), Fl (frequency- shift keying), and A9 (composite transmis- sions such as multi- channel radio teletype- writer signals).
