INSTALLATION

Transceiver installation

Plan the location of the transceiver and microphone before starting the installation. Choose a place in the vehicle that is easy to operate and does not interfere with the driver or passengers. The unit should be reliably placed on a solid surface. Install the mounting bracket and use self-tapping Fasten with screws.

ALAN9001 mobile antenna

The antenna is an important factor affecting the transmission and reception, for this reason we strongly recommend

With a high-quality antenna installed on the Alan 9001, you can have an advanced transceiver. Don't degrade its performance by installing a low-quality antenna.

Only a properly matched antenna system can fully radiate energy when transmitting. Our commercial research institutions can help you select the suitable antenna to meet your needs.

For mobile installations (ships, vehicles, etc.), a quarter-wavelength whip antenna can get good results. The most effective and practical is to install it in the middle of the rear deck or mast baffle.

A short whip antenna is the easiest to install, but not as effective as a quarter-wavelength whip antenna

For marine installations, ask your dealer for information on suitable grounding systems to prevent accidents.

Warning: When the standing wave ratio exceeds 2: 1, it may cause damage to the transmitting components.

Ground

Most new cars and trucks use 13.8V

DC negative grounding system. Some older cars and large trucks use the positive grounding system. The common way to identify the negative grounding system is to connect the battery's negative (-) terminal to the vehicle's frame (metal) or engine body. The polarity of your vehicle may be uncertain, contact your vehicle dealer for a clear answer.

Warning: Alan 9001 is designed to work only in 13.8V DC, negative grounded system. Operation at other voltages or polarities may cause fire, damage to the transceiver and other dangers.

ALAN9001 power cord connection

The red wire (with fuse) is used to provide the energy wire connected to the "hot" end (positive), and the black wire is grounded. When the unit is transmitting, you can connect the positive pole directly to the battery or power line.

operating

Choose a frequency

VFO operation

It is very easy to use VFO in this machine. First make sure that the F.Lock key is not pressed and then turn the knob until the required working frequency. The step size of the VFO is increased between 10KHz, 1KHz or 100Hz. The step size increment is indicated by the one with the underline on the rightmost three digits of the displayed frequency. To change the VFO step size, press the SPAN button until the desired step size appears on the black line. When you use VFO, you do not need to manually select the frequency band, because this is fully automatic, so the tuning range continuously runs through the entire operating frequency range.

ALAN9001 channel selection operation

You can also use the channel buttons on the front panel or the up / down buttons on the microphone to select the operating frequency. The channel selection button will select any 10KHz channel in the frequency band: 50 channels are in A (28.000 to 28.4999MHz),

B (28.5000 to 28.9999MHz), C

(29.0000 to 29.4999MHz); 20 channels are at D (29.5000 to 29.6999MHz). The 10KHz channel is pre-made and cannot be changed in the program. When the unit of step up or down is very close to the 10KHz channel, do not tune the frequency + or -10KHz. When you reach channel 50 (D segment 20), pressing the channel button again will reach channel 1, and conversely when you are on channel 1, pressing the channel button will reach channel 50.

To select a band, press the band button until the letter of the band you want is displayed, which is above the channel number on the display.

If you press and hold the channel button, the unit will continuously lift from beginning to end in the channel of the pre-made program. In some ways, pressing the channel key will do the same.

ALAN9001 receiving scan

The reception scanning function will make it easy for you to find active frequencies when using this unit. You can scan 50 channels in frequency bands A, B, and C and 20 channels in frequency band D. The scanning is from low frequency to high frequency, and Use 10KHz steps.

Scan operation

To start scanning, press the SHIFT key and then the SCAN key. If someone is transmitting at the current frequency (the squelch is turned on), pressing the scan key will raise the same frequency. If the squelch is not turned on, the scan will be performed. The sweep will run through the selected frequency band until a strong signal sufficient to turn on squelch is encountered. It will stop at the frequency of continuous transmission. When the transmission stops, the unit will wait about 1.

5 seconds. You can also go back to that transmitting channel to listen. If you want to talk, you have to press the transmit switch on the microphone within 1.5 seconds, so your Alan

9001 can transmit on this channel, and scanning will stop for a while during transmission. To exit from the scan mode, press the Manual key. During the scan operation, you can use the memory channel scan by pressing the MEMO key.

See the programming mode section for details on memory channels.

CW ALAN9001 CW operation

This machine is very simple to use CW mode, as long as you choose your operating frequency, the mode switch is set to CW, and the plug of the CW key is inserted into the corresponding interface on the rear panel. (See the interface section of the rear panel for CW key information).

Use CW mode and an external electric key to select an operating frequency. The mode switch is set to CW. Now you can perform manual report operation in CW mode (if you stop sending for more than 1 second, then switch to the receiving mode). Alan

There is a side tone oscillator in the 9001 for your convenience. When the key does not match the standard or there is no external key in CW mode, it will not be able to report.

CW receive and adjust the tone, you can use VFO or RIT to tune (note: adjusting RIT will not affect the frequency display)

USB / LSB / FM operation

The unit uses USB, LSB, AM and FM modes for voice communication. It is very simple. Just select the operating frequency you want, tune the mode switch to the desired type of operation, and use the PTT switch to control transmission and listening. To fine-tune the received signal in USB or LSB, you can use VFO or RIT to adjust. (Note: Using the RIT knob to fine-tune the receiving frequency will not affect the frequency display)

When in a high noise environment, you can use the microphone gain controller. Pressing the microphone gain controller will reduce the output of the microphone, and pressing it again will restore the normal condition.

ALAN9001 noise cancellation and automatic noise suppressor

Noise cancellation and automatic squelch are specifically designed to eliminate noise. You can choose to use only squelch, only auto squelch, or both. Whenever the NB / ANL button is pressed, the next function is selected. When you reach the last function, press it again to return to the first function. They can effectively eliminate interference from vehicle ignition systems.

Frequency lock

The frequency lock function is used to lock the frequency to prevent inadvertent changes. Need to lock the frequency. Press the F.Lock key to release the frequency lock. Press the F.Lock key again.

Warning sound controller

It enables you to release or not emit a short "beep" when you release the PTT button (except CW mode) when transmitting. This is very useful when using USB or LSB mode, because it allows you to know what the working state is after you stop transmitting. Pressing the BEEP button will allow a short "Beep" sound, and pressing it again to disable.

Multifunctional instrument

This is a very useful feature, multi-function meters are part of this machine and each has a number. They are:

S / RF RF Level Meter

MOD ALAN9001 MOD modulation table

SWR CAL VSWR Calibration Setting

SWR standing wave ratio read

Each time you press the METER button, the next function is selected. When you reach the last function, press it again to return to the first function.

RF level meter S / RF METER

The RF level meter function provides a visible indication of the strength of the relevant listening frequency signal and the associated transmit power. Using the S / RF meter function, press the METER button until the meter display stops on the "RF" display. Whether you use transmitting or receiving (S mode) the meter relies on the automatic switch function to switch. When receiving, the meter will return to S function.

Modulation table MON METER

This function gives you a modulation intensity indication when you are transmitting. This meter has no effect when listening to signals. Using the MOD function, press the METER button until the meter display stops on the "MOD" display

SWR CAL ALAN9001 VSWR Calibration Setting SWR CAL

This meter is a meter that calibrates the standing wave ratio in the multi-function meter. First select the CW, AM or FM mode, then press the METER button until you see the small triangle and CAL on the meter. Or CW key (if installed) to adjust SWR

CAL until the indicator bar reaches the small triangle, complete this step, and then use "SWR METER" to prepare to check the standing wave ratio.

Note: Don't forget that all emissions must be fully identified, and remember to listen on this frequency before transmitting.

ALAN9001 standing wave table

(SWR METER)

Prepare to check your Alan after calibrating the standing wave table with SWR CAL function

9001 and the standing wave ratio of the antenna system. Press the METER button until "SWR" is displayed. In this state, press the transmit button on the microphone or the CW key (if installed). The standing wave ratio will be displayed.

Note: If you use voice in LSB or USB mode, you will not be able to see a stable VSWR indication, because there is no carrier transmission in these modes. To see a stable standing wave ratio indicates that you must be in CW, AM or FM mode when transmitting.

Warning: When the standing wave ratio exceeds 2: 1, it may cause damage to the transmitting components.
