The term VFO historically means ‘Variable Frequency Oscillator’ and today refers to a tunable data storage which contains frequency, step, step-adjust, attenuator etc. Pressing the [VFO] key each time will select the one VFO out of five. Each VFO has a specific function under certain configurations. VFO-B --- Used for manual search between VFO-A frequency to VFO-B frequency](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-24.png)
![24 VFO-C --- Used to transfer frequency from the memory channel VFO-D --- Used to transfer frequency from the search channel VFO-E --- Used to receive frequency below 25 MHz while in dual frequency receive mode The AR5001D has an auto mode setting, therefore, in most cases a proper receive mode and frequency steps are automatically selected. 3-5-1 TUNING FREQUENCY 3-5-1-1 ENTERING A FREQUENCY USING THE NUMERIC KEYPAD While in VFO mode, enter the required frequency using MHz format followed by the [MHz] key. (Example) Frequency entry of 81.3 MHz Press the [8] key. Press the [1] key. Press the [.] key. Press the [3] key. Press the [MHz] key. (Example) Frequency entry of 1134 kHz (1.134 MHz) Press the [1] key. Press the [1] key. Press the [3] key. Press the [4] key. Press the [kHz] key. Aborting frequency input If you do not wish to complete the frequency data input, press the [CLR] key before completing the input sequence with the [MHz] key. Correcting frequency input Press the [UP] key to delete the entry from the right hand side. 3-5-1-2 CHANGING FREQUENCY USING THE MAIN DIAL In VFO mode, the active VFO frequency may be ‘tuned’ in using the main dial which is mounted on the right side of the front panel. Rotate the dial ‘clockwise’ to increase frequency or turn 'counterclockwise’ to decrease frequency. 3-5-1-3 CHANGING FREQUENCY USING [UP] KEY OR [DOWN] KEY The [UP] and [DOWN] keys provide a convenient method to change the frequency. The speed the receiver steps up or down depends on the step size which is set to default to auto. In auto mode, step size, receiver mode etc. are taken from the factory pre-programmed band plan but](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-25.png)
![25 may be overridden at any time. Press the [UP] key to tune the receiver upward in whichever step size is selected, use the [DOWN] key to tune the receiver downward in frequency. 3-6 RECEIVE MODE Due to the necessities of signal bandwidth, channel occupancy and transmission efficiency, different receive modes are used by various services. The tuning step and receive mode are allocated by departments of Governments following international discussions so they are not consistent throughout the world. For this reason, it is necessary to change receive mode in order to monitor various transmissions. For your convenience, receive mode and tuning step size have been pre-programmed into the AR5001D auto mode band plan data at the factory to simplify the operations of the receiver, especially while you familiarize yourself with the functions. If needed, the defaults may be manually overridden at anytime so that you may select an alternative receive mode and tuning step on any frequency. AM – Amplitude Modulation Used by broadcast services throughout the world on long wave, medium wave and shortwave. AM is also used by VHF airband, UHF military airband. SAM – Synchronous AM Helps to listen to SW (Shortwave) AM broadcast stations with fading signals. FM – There are two common types of FM (Frequency Modulation): NFM – Narrow Band Frequency Modulation Provides high quality communication for relatively short distance operation. FM uses a greater frequency bandwidth than other modes. NFM is the most common mode used above 30 MHz with the exception of the airbands. NFM is widely used on the VHF bands: VHF marine band, 2m amateur band, 70 cm amateur band, PMR (Private Mobile Radio) and utilities. In the absence of a signal, the background white noise may appear quite loud. For easier listening, the squelch control should be rotated clockwise until the background noise disappears; this should be carried out while no signal is present. The point at which the background noise is cancelled is known as the threshold point. Do not advance the squelch control more than necessary or the receiver will appear to be desensitized and weaker signals will be missed.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-26.png)
![27 To activate auto mode or reconfirm its selection while in VFO mode, press and hold the [MODE] key for two seconds. “AUTO” will appears above the frequency portion of the LCD. Note: Auto-mode is cancelled as soon as the receive mode, tuning step or other related data are changed. Remember that auto-STEP and auto-MODE are linked, reselect AUTO MODE if either have been adjusted and you require the auto band plan selection. 3-6-2 RECEIVE MODE SELECTION Any receive mode may be selected at any frequency within the receiver’s frequency coverage. To access the receive mode menu, press the [MODE] key. The following modes are available: FM stereo, FM, NFM, SFM, WAM, AM, NAM, SAM, USB, LSB, CW, ISB, and AIQ. Use the sub dial to select the desired mode. To accept the selection, press the [MHz] key. 3-7 CHANGING THE FREQUENCY STEP The specification for channel occupancy, step (separation) and mode are decided by and allocated by the Departments of Governments following international discussions. The allocation of frequency bands are not the same all over the world and channel separation (step) varies from band to band. As an example, the channel separation (step) for the MW (medium wave) band in the U.S.A. is 10 kHz, and is 9 kHz in Europe and Japan. For above reasons, it is necessary to change the frequency step size according to the local band plan. The AR5001D has been pre-programmed at the factory with all the band plan data (specific to each market area) so that the AR5001D will automatically select the appropriate step size and mode for the frequency chosen. This greatly simplifies operation of the receiver while you are familiarizing yourself with all the functions.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-28.png)
![28 The pre-programming of step size may be manually overridden so you may choose alternative settings at will or when band plans are updated. If you wish to change the default tuning frequency step, press the [STEP] key. The LCD will display the current frequency step and the blinking “STEP” while waiting for the new parameter. Use the sub dial to select the desired step. To accept the displayed tuning step size, press the [MHz] key. The tuning step size may also be programmed in 1 Hz (via the keypad) so that unusual step sizes other than those stated are possible. The acceptable step size range is less than 1 MHz in 1 Hz steps. 3-8 IF BANDWIDTH The IF bandwidth selects how SELECTIVE the receiver will be when monitoring signals off air. However, it is not simply a case of using the narrowest filter at all times; particular modes require differing amounts of bandwidth in order to operate. Otherwise the receive system will not produce intelligible sound. Correct receive mode and IF bandwidth must always be selected for optimum reception. If the bandwidth selection is too narrow, distortion or signal break-up may occur. If the bandwidth selection is too wide, adjacent interference may be encountered. For this reason, a selection of IF filter bandwidths are provided as standard.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-29.png)
![29 Typical examples of receive mode and IF bandwidth are: 300 kHz – VHF FM broadcast 200 kHz – VHF FM broadcast 30 kHz, 100 kHz – Wireless microphone, etc. (30 kHz for satellite FAX, too) 15 kHz – PMR, amateur band, etc. FM 6 kHz may also be used 6 kHz – VHF/UHF airband, short wave broadcast, medium & long wave, PMR, etc. 3 kHz – Short wave amateur band, short wave utility such as oceanic airband etc. 500 Hz – Morse code used by radio amateurs and some marine traffic on short wave An appropriate IF filter is automatically selected when auto mode is selected. However any combination of IF filter and receive mode is possible in the manual mode. When you have manually selected an IF filter bandwidth, auto mode will be cancelled, but the receive mode, frequency step, etc will be retained until they are changed manually. 3-8-1 MANUALLY SELECTING IF BANDWIDTH Press the [FUNC] key, and then press the [3] key. Select a new bandwidth from the list by rotating the sub dial. To accept the new bandwidth selection, press the [MHz] key.

Memory read is very straightforward and quick when compared to retyping all data. 6-1 MEMORY CHANNEL OVERVIEW Think of memory channels as pages in a notebook each of which is numbered to identify it. Data may be written to each new page (memory channel) and each page may be overwritten with new data, so they can be used over and over again. The AR5001D has 2,000 memory channels and one priority channel. Each memory channel may hold: One receive frequency Receive mode Tuning step Frequency step adjust Attenuator setting Text comment of up to twelve characters De-emphasis](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-42.png)
![42 Antenna input AGC mode CTCSS DCS Auto notch The alphanumeric comment may be used to ease identification at a later date. The 2,000 memory channels are divided into 40 banks, and each bank has 50 channels. The memory banks are identified by the first BANK number 0, 1, 2, 3, …, 48, 49 and the individual channels are numbered from 00 to 49. (Example): “1234” is the location: memory bank “12” and memory channel “34” The data contents of memory and search banks are held in an EEPROM so that no backup battery is required for memory retention. The stored data may be quickly and easily recalled, changed or deleted using the memory recall and delete functions. Note: When the receiver is switched OFF, all VFO data will be automatically stored into EEPROM memory storage. 6-2 STORING VFO FREQUENCIES AND DATA INTO MEMORY The process to save a displayed VFO frequency to memory is as follows: 1. In VFO mode, select the required frequency, mode, attenuator etc. 2. Press and hold the [MHz] key for two seconds. The AR5001D will automatically find the next available vacant memory channel. 3. Using the keypad, select the desired memory location (bank and channel). 4. Add a text comment (optional) or delete an existing comment. 5. Press the [MHz] key to exit the menu and save the data to the specified memory location. (Example) Storing the frequency of 123.500 MHz into memory bank “3” location “25” (0325) while in VFO mode with the text comment of “AIRBAND”.

Note: It is important that you do not confuse SCAN and SEARCH modes. SEARCH mode (covered later in this manual) automatically tunes the receiver through all frequencies between two specified frequency limits looking for active frequencies. 7-1 SCAN – OUTLINE INTRODUCTION During scan, the AR5001D automatically recalls memory channels which contain data in numeric order and monitors looking for activity. When an ‘active’ memory channel is located (when a signal is found and the squelch is open), the AR5001D will temporarily stop scanning. 7-2 STARTING SCAN Presuming that some memory channels are programmed with data, start the scan process with one press of the [SCAN] key. The “SCAN” is displayed on the middle left of the LCD to indicate that the scan process has been started, a bank number will be also be displayed representing the current bank. Ensure that the squelch is set to threshold point so that background noise is cancelled and the squelch closes (otherwise scan will not operate). When scan has been selected, only the currently displayed memory bank which contains data will be scanned, and receive mode and frequency are not important. Any memory channels which contain no data (empty) will be ignored and skipped.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-46.png)
![46 7-3 SELECTING A SCAN BANK The memory bank identifier (such as “03”) will be displayed on the middle right of the LCD. If more than one memory channel is programmed into the current memory bank, and when an ‘active’ channel has been located (busy, so the squelch opens), the scan process will temporarily pause on the active channel.

The priority checking is accomplished by momentarily tuning the receive circuit to the priority frequency to see if it is active. If the activity is found, the AR5001D will remain on the active frequency until the signal disappears. If no activity is detected, the receiver returns to the VFO frequency, scan channel or search bank from where it originated. The priority function has a large number of applications and is particularly useful for keeping an eye on a distress frequency while scanning or searching another frequency band.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-87.png)
![87 Note: Depending upon the frequency and mode stored as priority, an audible click may be heard when the priority function is in operation. This is quite normal and is caused by the internal switching of circuitry necessary to accomplish the frequency change. 11-6-1 CONFIGURING PRIORITY CHANNEL Once activated, the frequency is periodically checked for activity based on the preset period set by the configuration menu.

This has the effect of reducing the sensitivity of the receiver.](https://usermanual.wiki/AOR-USA/AR5001D/User-Guide-1772473-Page-88.png)
![88 The normal position for the AR5001D RF gain control is fully counterclockwise when set at its most sensitive. As the control is rotated clockwise, the S-meter will advance to indicate what strength signal is required to produce solid and readable results. The control is most useful on SSB most where RF gain should be adjusted so that the peaks of SSB signals just deflect the S-meter. This will greatly reduce the level of background noise especially during pauses in speech or inactivity. Note: RF gain control is not available in FM mode. Before using the RF gain control, the AGC must be set to off. To activate RF gain control, press the [FUNC] key, and then press the [6] key. To change RF gain, rotate the squelch knob. To de-activate RF gain, repeat above steps. 12 PC CONTROL 12-1 USB INTERFACE The USB (type B) connector is designed to connect directly to the USB port of a PC.
