1、 1 06/01/2011 Programming Alinco -135T, 235T, and 435T VHF/UHF Radios RADIO DISPLAYS and CONTROLS: The front panel of the radio is shown in Figure 1. Figure 1 Turning The Radio On: The power switch 1 is the pushbutton in the upper right hand corner of the radio. Volume Control: The Volume Control 2

2、is the small knob to the left of the Power On Pushbutton. Tuning Knob: The Tuning Knob 3 is the large knob below the Volume Control and Power On Pushbutton. Function Keys: There are 6 function keys 4 9 located below the display. The keys are labeled as follows: SET MW SHIFT LOCK H/L D FUNC V/M MHz T

3、S/DCS CALL SQL The functions engraved on the keys (the lower set of functions shown above) are performed by directly pushing the appropriate keys. The functions labeled above the keys (the upper set of functions) are second level functions. These functions are performed by first pushing the Function

4、 (FUNC) key followed by the key under the desired function label. The exception is the SET function. To access the SET function, push and hold the FUNC key for 2 seconds or more. This will cause the radios Menu to appear on the screen. You scroll through the menu by pushing the SQL key. Exit the SET

5、 mode by pushing either the FUNC or V/M key. End Function Selection: Usually, the radio will return you to the normal display after selecting a function. Occasionally the radio will remain in the function selection process. If this occurs, and you wish to terminate a function, push the V/M function

6、key to terminate or close function selection. 2 FUNCTION KEY SUMMARY: Level 1 Functions FUNC:NoneFunction V/M:VFOMemory MHz:146.445146._ _ _(Example) TS/DCS:NoneTT SQDCS CALL:Selected FreqCall Freq SQL:NoneSet Squelch Level (Only works in VFO mode) Level 2 Functions Push & hold FUNC for 2 Sec: Norma

8、ushing the Function (FUNC) key followed by the TS/DCS key will “lock” the controls on the radio to avoid unintentional changes. A skeleton key icon will appear on the upper part of the display indicating that the radio has been placed in the Lock mode. When in the Lock mode, push the FUNC key follow

9、ed by the TS/DCS key to unlock the radio and return it to normal mode. NOTE: The examples used in the operating instructions given below are for the 2 meter DR- 135T radio. However, operation of the 220 MHz DR-235T radio and the 440 MHz DR-435T radio are identical SIMPLEX OPERATION: Simplex is the s

10、implest mode of operation. Simplex does not involve a repeater and is used to communicate with a “near by” station that is approximately in your line of sight. Line of sight could be several miles away if you are on top of a hill, or less than a half mile if you are surrounded by hills, buildings or

11、 other obstructions. To operate simplex, tune the radio to the frequency that you and the station that you want to talk to agree upon. In addition, turn off the radios repeater frequency shift function. Frequency shift is utilized only when communicating through a repeater. It is not used for simple

12、x operation. Finally, set the radios output power to an appropriate level (usually low or medium power), set the squelch control to eliminate background noise, and turn the volume control to a comfortable listening level. You are now ready to begin simplex communications. These steps are described i

13、n more detail below Frequency Selection: Alinco radios have two operating modes, VFO mode and memory mode. To set the radio to the correct frequency you must be in the VFO mode. If the radio is in the memory mode, an M will appear on the left edge of the display. If you are in the memory mode, the V

14、/M function key must be pushed to enter the VFO mode (the M will disappear from the display). The Variable Frequency Oscillator (VFO) is the module that controls the radios frequency. Turning the Tuning Knob causes the radio to change frequency in very small steps. If the person that you want to tal

15、k to is on a frequency of 147.555 MHz and the radio is tuned to 144.000 MHz, it will take you all day to “crank” the Tuning Knob to a frequency of 147.555 MHz. To move across the band quickly (while in the VFO mode) push the MHz function key. The display will change to 144._. Turn the Tuning Knob 3

16、clicks. The frequency display will change from 144._ to 145._, then 146._, and finally 147._. Pushing the MHz key again puts the radio back in the normal mode. Now turn the Tuning Knob until you reach 147.555 MHz. Turn Off Shift: When communicating through a repeater, the frequency that you are list

17、ening to (the repeater output frequency) will be automatically changed (shifted) by the radio to the repeater input frequency when you begin to transmit. In simplex mode you do not want this to happen. In simplex mode, the frequency that you are listening to is also the frequency that you want to tr

18、ansmit on. To ensure that this happens, you must turn off the shift function. Notice that the word SHIFT is displayed above the MHz function key. Since SHIFT is written above the key, it means that you activate the Shift function by first pushing the Function (FUNC) key 4 and then the MHz key. Repea

19、ting this two keystroke operation will cycle you through three options, minus shift (a appears at the top of the display), plus shift (a + appears at the top of the display), no shift (neither a + nor symbol appears at the top of the display). It is this last option (no shift) that you want for simp

20、lex operation. Power Level: The Alinco radio has three transmit power levels, High, Medium, and Low. To minimize interference to others and to minimize the drain on your power supply or batteries, set the radio to the lowest power level needed to communicate with the person that you are talking to.

21、A good level to start with is Medium. On the Alinco, H/L (High/Low power) is written above the CALL key. This means that power selection is a second level function. Push the Function (FUNC) key followed by the CALL key to select power level. Repeating this set of key strokes will cycle you through t

22、he High, Medium, and Low power levels of the radio. For a Medium power setting, Mi appears in the upper left corner of the display. For a Low power setting, Lo appears in the upper left corner of the display. For a High power setting, neither Mi nor Lo appears in the upper left corner of the display

23、. Stop at the setting that you want. Squelch: Push the Squelch (SQL) function key. Turn the Tuning Knob counter clockwise until you hear continuous background noise (hissing). Now turn the knob the other direction until the hissing stops and the radio is quiet. Push the Squelch (SQL) function key ag

24、ain to terminate the function. This sets the sensitivity of the radio so that you can hear others without the nuisance of background noise. Volume Control: Finally set the volume control to an audio level that is comfortable. Receiving: You should now be able to receive the transmissions from the pe

25、rson that you want to talk with. Transmit: To transmit, push the PTT (Push To Talk) key on the microphone. Wait a second after pushing the PTT key before speaking to give the radio time to enter the transmit mode. If you do not do this, the first word that you speak may not be clearly transmitted. S

26、peak in a normal voice. Speaking too loudly will distort your transmission. Also, talk across your microphone, from the side, instead of directly into it. Talking directly into the microphone can cause background hissing. REPEATER OPERATION: Repeater operation permits communications over an extended

27、 area. A repeater located on a high hill or mountain top has line of sight coverage over a considerable area, often 15 to 20 miles. A repeater amplifies signals it receives on its input frequency and retransmits them on its output frequency. As a repeater user, you will listen to others on the repea

28、ter output frequency. This is the frequency that is listed for the repeater in repeater directories. For example, the output frequency for the Bozo Repeater is 147.885 MHz and the Grissom Repeater is 146.850 MHz. The repeater input frequency, for 2 meter repeaters, is offset or shifted either +600 K

29、Hz or -600 KHz from its output frequency. When you transmit to a repeater, the output of the radio must shift + or - 600 KHz, as appropriate, to the repeaters input frequency. The offset for both Bozo and Grissom is negative. The Grissom output frequency is 146.850 MHz so when you transmit to Grisso

30、m, your radio must transmit at a frequency of 146.250 MHz. You must program this + 5 or - offset into the radio in order to use the repeater. For example, for the Grissom repeater you select the offset. Most repeaters in metropolitan areas utilize an access tone to avoid receiving and retransmitting

31、 signals actually intended for a different repeater operating on the same frequency. This tone is known as a PL or CTCSS tone. There are actually 39 tones available for use ranging in frequency from 67.0 to 250.3 Hz. A repeater will only retransmit signals which contain its particular PL tone. For e

32、xample, the PL for Bozo is 127.3 Hz while that for Grissom is 94.8 Hz. To utilize a repeater, your radio must be programmed to transmit the PL tone which the repeater is expecting. If you dont, the repeater will ignore your signals. In some cases a repeater will not use a PL tone. For example the Oj

33、ai repeater on 145.400 MHz, minus offset, does not use a PL. In that case you will not program a PL tone into the radio for that repeater. Programming the radio to work with a repeater is similar to programming it for simplex operation with the addition of the +/- offset and the PL tone. The program

34、ming procedures for repeater operation follow: Frequency Selection: If the radio is in the memory mode (there is an M showing on the left edge of the display indicating memory mode), then push the V/M function key to place the radio in the VFO mode. Tune the radio to the output frequency of the repe

35、ater that you wish to use, 146.850 MHz for Grissom, using the same tuning procedures that were used to select a simplex frequency. Select +/- Shift: Select the appropriate +/- offset for the repeater that you plan to use. This is done with the SHIFT key. The word SHIFT appears above the MHz function

36、 key which means that the FUNC key must be pushed followed by pushing the MHz key to activate the Shift function. Performing this two keystroke operation causes a to appear at the top of the display indicating that the radio is now set up for a negative offset. Performing the two keystroke operation

37、 again causes a + to appear at the top of the display (replacing the minus) indicating a + offset. Performing the operation again causes the + sign to disappear, indicating that you are back in the Simplex mode (no offset). Perform the operation as many times as needed to achieve either a or a + off

38、set, as appropriate for the repeater that you will be using. Select PL Tone: If the repeater that you will be using requires a PL tone, then you must select the tone which the repeater expects. Tone is selected by pushing the TS/DCS function key. If no tone has been selected, pushing the key once wi

39、ll cause a T to appear at the top of the display plus a tone frequency. Turn the Tuning Knob until the tone frequency expected by the repeater is displayed. Complete the tone selection by pushing the V/M key to exit the selection process. The normal display will return, except that a T is now showin

40、g on the display indicating that a PL tone has been selected. Pushing the TS/DCS function key multiple times will cause the radio to cycle through T, TSQ, DCS, None, T, etc. Normally continue pushing the key until only the T is shown on the display. Some repeaters will transmit a PL tone as well as

41、receiving a PL tone. The tone that it transmits is the same PL tone that it expects to receive. If the repeater that you are communicating through does transmit a PL tone, then you may select either T or TSQ. If there is a distant repeater transmitting on the same frequency as your repeater, and if

42、your repeater transmits a PL tone, then by selecting TSQ you will receive only the transmissions from your repeater. You 6 will not hear the other repeater. This is a very nice feature. HOWEVER, if the repeater that you are using does not transmit a PL tone, then selecting TSQ will prevent you from

43、hearing your repeater. If your repeater does not transmit a PL tone, you can not hear your repeater, and you know you should be able to hear it, check your tone selection. If TSQ is selected, turn it off and select T instead following the procedures given above. If you do not know if your repeater i

44、s transmitting a PL tone, first select T. Verify that you can hear the repeater. Change the selection to TSQ. If you can still hear the repeater, then the repeater is transmitting a PL tone. If you can no longer hear the repeater, that means that it is not transmitting a tone. Select T and you shoul

45、d again hear the repeater. Recommendation: If the repeater you are using requires a PL tone, then: 1. Normally select the T mode. 2. Select the TSQ mode ONLY: IF you are receiving interference from a distant repeater on the same frequency, AND you have verified that your repeater IS transmitting a P

46、L Tone, OTHERWISE continue to use the T mode. We do not use the DCS functions on any of our local repeaters. If DCS is selected, turn it off. Power Level: Set the radios transmit power level to the lowest power needed for the repeater to clearly receive your signal. A good level to start with is Med

47、ium. Set this power level in the same way as was done for simplex operation. Squelch: Set the squelch in the same manner as was done for simplex operation. Volume Control: Finally, set the Volume Control to an audio level that is comfortable. Transmitting and Receiving: You are now ready to communic

48、ate with others via the repeater. Before beginning to transmit, make sure that the person that has been transmitting is really finished before starting your transmission. Then delay a little longer so that if someone has emergency traffic, they will be able to break in and use the repeater. If all i

49、s quiet, then you may transmit by pushing the PTT key on the microphone. Remember to wait a second after pushing the PTT key before speaking to give the radio and the repeater time to enter the transmit mode. RADIO MEMORY OPERATION: Programming radio simplex and repeater frequencies is a lot a work. After you have set up the radio for a particular simplex frequency or repeater, you can store that information into the radios memory so that you will not
