4 This is the NPX-138 radio from Northern Airborne Technology, Ltd of Canada which has been designated as CAPs aircraft VHF-FM radio of choice. FAA accepted for aircraft use 100 channels within the mHz VHF spectrum 100 channels within the mHz VHF spectrum Guard (priority) channel monitor capability Guard (priority) channel monitor capability Programmable from laptop computer in the field Programmable from laptop computer in the field [Page Up or NEXT 3

5 Introduction Otherwise, you may go to the Channel Display by lightly toggling the BRIGHTNESS switch, also labeled NEXT, either direction. HELP …if you want to search the built-in tutorials, you can press the white button marked help at this time. Page Up or NEXT NEXT 4

6 Page Up or NEXT Introduction The position of the EDIT switch governs the way in which the other switches operate. This is a pull-type lockout toggle switch DONT move this until you cover Part II, Advanced Training on field program options and scanning Page Up or NEXT Display, Channel, and Brightness. Display, Channel, and Brightness. The EDIT switch centered, the function of the other chief toggle switches are as labeled above them: 5

7 Some of the more obvious controls are right here: Main Volume - Adjusts receiver volume Display Type - Changes display mode Some of the more obvious controls are right here: Main Volume Main Volume - Adjusts receiver volume Display Type - Changes display mode Introduction Page Up or NEXT Some of the more obvious controls are right here: Main Volume - Adjusts receiver volume Display Type Display Type - Changes display mode Channel Select - Choose the channel you want Brightness - Adjust the screen brightness Channel Select Channel Select - Choose the channel you want Brightness - Adjust the screen brightness Channel Select - Choose the channel you want Brightness Brightness - Adjust the screen brightness 6

9 Lets cover these functions in greater detail Introduction There are two possible screen readout types to observe, and you may use which ever you prefer: This Alpha-Numeric readout………. Operating the Radio Page Up or NEXT 8

10 ……....Or this Frequency readout. Operating the Radio Page Up or NEXT 9

11 The DISPLAY switch lets you choose the display mode. Display Switch to the left shows the ID Display Operating the Radio Switch to the center is the Receive Display. This is the actual receive frequency for this channel Page Up or NEXT 10

12 Operating the Radio Switch to the right is the Transmit Display. The TX and RX frequency will most often be the same in airborne communications Exceptions will arise. See the number to the right of the RF frequency. This is the subaudiable tone, or CTCSS tone which is programmed for that channel Page Up or NEXT You recall from ROA training that a channel is comprised of 1) a radio frequency, and 2) a subaudible note, or tone, which rides underneath the voice audio and opens up other radios receivers The tone for this channel is 100 cycles, or Hertz Page Up or NEXT 11

13 In the interest of safety and confusion avoidance, its recommended that the radio is left in…… …this ID Display condition …this ID Display condition This is your preferred, typical view screen. …this ID Display condition This screen shows everything one really needs to know while in the air: The Channel, as known on our other VHF-FM radios The normal use or tasking for that channel Page Up or NEXT Operating the Radio 12

14 Getting StartedOperating the Radio Power display - HI = 10 Watts, LO = 1 Watt HI Power would be the normal setting CTCSS Tone On or Off ON would be the normal setting Page Up or NEXT 13

15 Operating the Radio Notice that we didnt specify the means for changing the variables such as tone, power, etc Once this radio is installed and programmed, it should just power up and operate as is Page Up or NEXT 14

16 Operating the Radio Part II, the Advanced User segment of this training series will cover the specifics of changing the options for tone, power, and other matters These functions need not be altered in any way, as long as the display reads as just specified Page Up or NEXT 15

17 Heres an overview of the other chief functions: On/Off and Volume - Traditional function and purpose Squelch - Push in to hear the weakest of signals Channel - Pick the channel of operation desired On/Off and Volume - Traditional function and purpose Squelch - Push in to hear the weakest of signals Channel - Pick the channel of operation desired Operating the Radio Page Up or NEXT 16

18 If one considers just this much, the NPX-138N works just like any other VHF-FM radio Turn on, set channel, adjust volume as required Set display mode and screen brightness Set aircraft comm panel as necessary Operating the Radio Turn on, set channel, adjust volume as required Set display mode and screen brightness Page Up or NEXT 17

19 If one considers just this much of the radios operation, it works just like any other VHF-FM radio Operating the Radio Leave the scan select on NORMAL, or centered 18

20 Press in the Squelch button to hear very weak signals If one considers just this much of the radios operation, it works just like any other VHF-FM radio Operating the Radio Leave the scan select on NORMAL, or centered Press in the Squelch button to hear very weak signals 19

21 Press in the Squelch button to hear very weak signals If one considers just this much of the radios operation, it works just like any other VHF-FM radio Operating the Radio Leave the scan select on NORMAL, or centered Change channels as required during mission Change channels as required Page Up or NEXT 20

22 Operating the Radio Set the Guard Volume Control counterclockwise to its lowest setting for now Switch the Guard Channel Select to channel 1 or 2 depending upon the needs of your local Command Page Up or NEXT So, just what is this Guard Channel feature, anyway? Page Up or NEXT 21

23 Page Up or NEXT Imagine your radio is actually --2 radios in one! You could work one channel while listening to another You could go off frequency with a ground team, and still catch a call on your primary channel from Mission Base (or from another air crew or ground team) You could be doing work with another agency on their channel, and still receive a CAP mission alert You could answer these calls without switching the dial Heres how to use the Guard feature: National F-1 and F-4 are default programmed as GD1& GD2 Use the Guard Select switch to choose which guard channel to monitor - the repeater or the air-ground frequency Leave the SCAN switch in NORMal mode for now Set the Guard Volume to a desired level Page Up or NEXT Use the Guard Select switch to choose which guard channel to monitor - the repeater or the air-ground frequency 22

24 Choose your other operating channel with the CHANnel switch, in the common fashion for channel selection If you hear a call and the lamp immediately to the right of the regular on-off-volume knob lights up, then that was on the regular channel as indicated on your display Answer that call in the regular fashion, you dont have to change or move anything on the radio to do so Page Up or NEXT 23

25 If you hear a call and the lamp just to the right of the Guard Channel (GD) knob lights up - If you hear a call and the lamp just to the right of the Guard Channel (GD) knob lights up - then you would: Adjust the GD Volume if necessary for good audio Change the SCAN/NORM switch to the bottom setting, which is labeled GD TX - Guard Transmit Page Up or NEXT GD TX Change the SCAN/NORM switch to the bottom setting, which is labeled GD TX - Guard Transmit All transmissions from you will now go out over the Guard Channel you selected with the switch GD1/GD2 Page Up or NEXT 24

26 Once all Guard Channel traffic is cleared, you would - Revert back to normal operation by switching the SCAN/NORM switch back up to where it was before Continue normal operations Adjust Main and Guard volumes, as necessary Page Up or NEXT It should be pointed out that Guard Channel/Regular Channel co-monitoring is no different than the way we use the aircraft aviation band comm radios… You can hear traffic on either one, but they both have their own volume and TX controls Simply set the NPX-138Ns two volume knobs as needed & answer either radio by means of the NORM - GD TX switch Guard Volume has a preset minimum volume level preset minimum Guard Volume has a preset minimum volume level Page Up or NEXT 25

27 NEXT for Answer Operating the Radio … And thats it !! So, Lets review just once more on the important stuff: Final Practical Review Toggle the switch labeled BRIGHTNESS/NEXT We know we need to see a channel display of one kind or the other, so we can use the radio. - You see this HELP screen, so you would do what in order to get past this screen and on to business? Page Up or NEXT 26

28 NEXT for Answer Final Practical Review Toggle the switch labeled DISP, for Display - You can display the Channel by Frequency or by its name or common usage. Choose this how? Page Up or NEXT 27

29 NEXT for Answer Final Practical Review Use the Guard switch, choose GD 2 for CAP-4, & youll hear calls on either frequency Were asked to go off to another channel to assist an outside agency on a mission or work a ground team How do we keep an ear out for Mission Base as well? Page Up or NEXT 28

30 NEXT for Answer Final Practical Review This switch all the way down, and speak to them ….and so youre on your agency assist and you hear a call from another CAP airplane on GD 2, which you know is CAPs Channel 4 Whats the fastest, easiest way to answer them? Page Up or NEXT 29

31 This is for timing Final Practical ReviewConclusion Thats it! Now that youve seen this, the radio owners manual should be reviewed -- while youre sitting in front of the radio if possible Theres absolutely no substitute for hands-on field experience Try these basic steps while youre on the ground, so that they become second-nature when youre in the air 30

32 Briefing on the basic use This is the end of the Introductory Level Briefing on the basic use of the NPX138N from NAT, Ltd Continue with the Advanced User Briefing to learn to use Scanning, Priority, and Direct Frequency or Channel Editing 31

33 DEWG CAP 9/30/00 DEWG CAP 9/30/00 NAT NPX138N VHF-FM Radio Part II Advanced User Training on the use of Scanning, Priority, and Direct Frequency / Channel Editing DAFB Air Mobility Command Museum Dover, Delaware 32

34 [Page Up] or NEXT This is the Advanced Training for use of the NPX-138 from Northern Airborne Technology It is assumed for the purposes of this advanced training that the operator/student has at least some experience with frequency agile radios Examples of such are aviation band comm radios or certain VHF-FM applications Remember, this means you may press any key to continue Specific assumptions are made that the student understands the purpose of certain VHF-FM specific matters [such as CTCSS tones], and is comfortable with prior instruction on general use as covered under Part I of this user training series [Page Up] or NEXT 33

35 Proceed further if you desire information on Channel Scanning, Priority Scanning, and in-the-field frequency entry. Do so only if you feel entirely confident with the preceding material under Part I, the Basic NPX-138N User Training. [[Page Up] or NEXT 34

36 Many radios will arrive with the default screen shown here. Your radio can be re-programmed to come on and go directly to the channel position of your choice. For now, lets assume this is what you see…. [Page Up] or NEXT Review One makes display selections by means of 4 toggle switches. Most references to adjustments will be with respect to one or more of these switches. [Page Up] or NEXT 35

37 NEXT IF your radio does power up with this screen, simply move the NEXT {Brightness} toggle to the left or right Review [Page Up] or NEXT We now see the normal operating screen [Page Up] or NEXT 36

38 The EDIT switch is normally centered so that important settings dont get messed up You can, however, make corrections to TONE, POWER, SIMPLEX/DUPLEX, SCAN & PRIORITY choices by this means XX X Review [Page Up] or NEXT And how, exactly, do I do that?, you ask. [Page Up] or NEXT 37

39 The important mode selections are STEPPED through, one at a time, by moving the EDIT switch to the right -- to the STep position Setting Options [Page Up] or NEXT 38

40 The important selections are STEPPED through, one at a time, by moving the EDIT switch to the right -- to the STep position The EDIT switch in this position changes the mode of these other two switches to NEXT and SELECT, as labeled below them Setting Options [Page Up] or NEXT 39

41 Toggling the switch labeled NEXT takes you through the different modes or settings which can be adjusted, such as Power, Tones, Scan, etc These settings are global - They affect all channels, not just the one displayed at the time Setting Options [Page Up] or NEXT 40

42 The SELECT toggle makes the desired change, such as (selection) On, (selection) Off, or setting High or Low, etc The key is knowing what it is you want or need Setting Options [Page Up] or NEXT 41

43 [Page Up] or NEXT So we know now that we can change various parameters by running thru them one at a time with the NEXT switch Setting Options So we know now that we can change various parameters by running thru them one at a time with the NEXT switch NEXT SELECT And we know we can execute the change by toggling the SELECT switch. [Page Up] or NEXT 42

44 The first variable which comes up is the Simplex/Duplex selection One usually thinks of Simplex operation as direct, radio- to-radio contact, while Duplex is most often associated with repeater use Setting Options [Page Up] or NEXT The Transmit mode should be left in DUPLEX, so that repeater channels will work. Duplex channels use one frequency for transmit and another for receive [Page Up] or NEXT Channels meant to be Simplex, such as 1 thru 4, have been programmed with TX and RX the same so they will act as simplex channels just fine [Page Up] or NEXT The next variable in this sequence is the POWER OUTPUT with a choice of HI, which is 10 Watts of power (max allowed in CAP air service), or LO, which is 1 Watt [Page Up] or NEXT 43

45 The TONES selection is the next variable You recall from ROA training that a channel is comprised of 1) a radio frequency, and, 2) a sub- audible note, or tone, which rides underneath the voice audio and opens up other radios receivers The choices for the TONES setting are: ON, OFF, or TX ONLY. Leave ON for most general use Setting Options [Page Up] or NEXT IF you need to hear a channel without your receiver tone filter on, TX ONLY does this. Dont ever set to TONES=OFF. This cuts TX tones as well & youll forget, leaving it unusable for future air crews. 44

46 [Page Up] or NEXT Setting Options The next changeable option is the TONE DISPlay. In order to explain its significance, take a look at the main screen again, in this DISPlay mode Assume youre now in the RX Display mode [Page Up] or NEXT The TONE DISPlay mode determines how that tone is labeled, for programming or reference purposes Choices are the audio frequency itself, such as 100.0, or the EIA# such as 12, or other nomenclatures used by the Motorola or Wulfsberg companies [Page Up] or NEXT 45

47 Setting Options We refer to tone types in both simplex and repeater service by their frequency Hz, Hz, etc [Page Up] or NEXT This will become important if you should need to install other users channels in the field [Page Up] or NEXT 46

48 So, TONE DISPlay is simply a choice of ways to refer to the CTCSS tones you may need to enter in the field Lets go back to the STep SELECTion we just left, showing the TONE DISP option and continue from there…... Setting Options The next selectable options are the SCAN bank designator and the PRIORITY selector These two functions and their set-up are related, so well cover them together in just a moment [Page Up] or NEXT 47

49 Another selection along in the Step process lets you choose the channel you see when you POWER-UP the radio Setting Options [Page Up] or NEXT 48

50 Once all of the STepped variables have been set, return the EDIT switch to the center position. Setting Options [Page Up] or NEXT Consider leaving all settings as show above: DISPlay Switch = ID [Page Up] or NEXT SCAN Switch = Normal [Page Up] or NEXT Guard1/Guard2 = G1 or as directed by local command [Page Up] or NEXT Channel = Air to Ground or as directed by your local command [Page Up] or NEXT Verify that you left : POWER = HI [Page Up] or NEXT TONES = ON [Page Up] or NEXT EDIT Switch = [Page Up] or NEXT We didnt go through all selections possible within each variable option category Most people wont need to change any of these aforementioned selections, but its good to know how to do so in the field or on a mission [Page Up] or NEXT 49

51 Advanced User Training OK, lets cover Channel Scan and Priority Scanning is the process of allowing the radio to listen to many channels in a repeating sequence The receiver stops on a channel if its in use, so you can hear if theres traffic of interest to you [Page Up] or NEXT 50

52 Advanced User Training S C The display, in ID DISPlay mode, will show S C to the right of the Channel Name if its on the Scan List [Page Up] or NEXT If you choose to use the SCAN feature, first put your radio on the primary Channel youre going to be working [Page Up] or NEXT Then, move the SCAN/NORM switch upwards and the radio will begin scanning channels [Page Up] or NEXT 51

53 Advanced User Training If the home channel becomes busy, the receiver will revert back there for you S C [Page Up] or NEXT If a channel becomes a nuisance, toggle the CHANnel switch to - to make the radio ignore that channel [Page Up] or NEXT This temporary bypass request is reset once you leave the SCAN mode, or if you power off the radio [Page Up] or NEXT 52

54 Advanced User Training In addition to being on the normal Scan list, certain channels can be designated as Priority channels S C P I [Page Up] or NEXT Youll see a P I or P 2 to the right of the Channel Name if this channel was programmed as a Priority channel [Page Up] or NEXT If a Priority channel becomes active while youre scanning, the radio will go to the priority channel [Page Up] or NEXT 53

55 Advanced User Training S C P I This is NOT the same as a guard channel. A scanned channel is monitored in sequence; A Guard channel is monitored simultaneously regardless of other activities [Page Up] or NEXT A channel is made a Priority channel at the time of programming; This can be changed in the field by persons who know how to edit or enter channels in the field [Page Up] or NEXT = = This is NOT the same as a guard channel. A scanned channel is monitored in sequence; A Guard channel is monitored simultaneously regardless of other activities 54

56 We now know that there is a batch of channels listed in a main Scan group, and that there are certain ones among this group which are Priority selections How do we decide if we want to simply scan those in the Scan group batch, or if we want to be interrupted by Priority channels as well? Advanced User Training S C P I [Page Up] or NEXT 1. Move the EDIT/STep switch to the right [Page Up] or NEXT 2. Use the NEXT toggle to find the SCAN options (Note that at present, only the normal scan list is chosen) [Page Up] or NEXT 3. SELECT whether to scan just the LIST of scan-channels, or if you want the scan-LIST and the PRIority feature to be engaged [Page Up] or NEXT NEXT

57 Advanced User Training The use of scanning is a subject best covered in detail under self-study in front of the radio with the manual S C P I Please avail yourself of this time-honored training technique [Page Up] or NEXT 56

58 BREAK Please take a 15 Minute recess before continuing with this program Please load the file NPX138 2of2 Advanced Training.ppt for the rest of this training session. 57

59 Part 3 58

60 Advanced User Training Now for the interesting part: Field Programming S C P I 59

61 Advanced User Training OK, you asked for it The truth is that once you practice this procedure on an empty channel, youll find it follows very predictable steps from operation to operation [Page Up] or NEXT 60

62 You need to know these things to enter a channel: Advanced User Training Whether this is to be included in the Scan List S C P I [Page Up] or NEXT Whether this is a Narrow or Wide Band FM channel [Page Up] or NEXT A name for this channel up to 10 characters long [Page Up] or NEXT The TX & RX frequencies and subaudable tone [Page Up] or NEXT Is this channel already programmed in this radio? [Page Up] or NEXT 61

63 Advanced User Training Lets first dial up the radio frequency Move the EDIT switch to the LEFT this time Well call this the EDIT CHannel selection [Page Up] or NEXT The DISPlay switch now shows what it is that youre changing - The name display, transmit frequency, receive frequency, etc [Page Up] or NEXT 62

64 Advanced User Training Well start with the DISPlay switch in the r [Page Up] or NEXT We learned that the DISPlay switch in the (RX) position shows the Receive frequency [Page Up] or NEXT Its the same with programming: Youre programming whatever the DISPlay is set to show at the time [Page Up] or NEXT RX 63

65 Advanced User Training Being as the DISPlay now shows the RX display, well begin programming the Receive frequency r [Page Up] or NEXT The NEXT switch chooses the digit to be edited [Page Up] or NEXT The SELECT switch makes the number change [Page Up] or NEXT 64

66 Advanced User Training After each digit is SELECTed, go to the NEXT one and keep going until the whole frequency is entered r [Page Up] or NEXT Then, go NEXT even further over to the right, and enter the CTCSS tone as needed. [Page Up] or NEXT Thats it for the Receive frequency [Page Up] or NEXT 65

67 Advanced User Training Now that we have an RX frequency, well do the exact same thing for the Transmit side of the formula rt [Page Up] or NEXT Change the DISPlay switch to the right, to the TX setting [Page Up] or NEXT Duplicate the frequency and tone which was put into the RX side (unless the circumstance directs otherwise) 66

68 Advanced User Training The next step is to assign the Identification, Channel Bandwidth and Scan List inclusion SCSC [Page Up] or NEXT This step changes items seen in the ID screen, so we need to switch the DISPlay to ID to make these changes [Page Up] or NEXT Again, use the NEXT switch to choose which space to edit, and then SELECT the letter, numeral, symbol needed [Page Up] or NEXT 67

69 Advanced User Training For the time being, well assume all field entries will be in Wide Band format, as used by our other radios at present The next choice is for Wide or Narrow FM channel width W SCSC [Page Up] or NEXT Select whether this channel is to be put on the Scan List for later use in channel scanning [Page Up] or NEXT 68

70 Advanced User Training W SCSC Finally, return the EDIT switch to the center position [Page Up] or NEXT Finally, return the EDIT switch to the center position 69
