AOR AR-DV1

Multi-mode Digital Voice Receiver

The Next Generation Multi Digital Mode Demodulation Receiver

The first scanning receiver of its kind to receive and decode virtually ALL popular digital modes including:

  • MOTOTRBOTM
  • DMR
  • dPMRTM
  • APCO P25
  • NXDNTM
  • Icom D-StarTM Digital CR
  • Yaesu
  • Kenwood®
  • Alinco EJ-47U

PLUS conventional analog signals including: AM, wide and narrow FM, upper and lower sideband and CW modes

The AR-DV1 can be operated independently or computer controlled for easier programming and monitoring. It features:

  • wide band reception from 100kHz to 1300MHz*
  • a micro USB computer interface
  • built-in SD/SDHC card reader for audio recording
  • CSV memory data capability for frequency uploads/downloads and firmware updates
  • 2000 memory channels (50 channels X 40 banks) that can be stored in the receiver using individualized data for each channel that includes frequency, alpha-numeric channel labels, mode, and more

The AR-DV1 gives monitoring operators the ability to monitor a wide variety of digital and analog frequencies, making it particularly useful in areas where government, law enforcement, amateur radio operators and public safety agencies use different digital formats.

Available in a professional version or in a U.S.A. consumer* version, in addition to its multiple digital mode capabilities, the AR-DV1 also receives analog modes including AM, wide and narrow FM, upper and lower sideband and CW.

Giving monitoring operators the ability to receive a wide variety of digital and analog frequencies, the AR-DV1 can be used by military, federal, state and local law enforcement agencies, emergency managers, diplomatic services, news-gathering operations, and home monitoring enthusiasts in areas where government, law enforcement, amateur radio operators and public safety agencies use different digital formats.

Other features:

  • wide band coverage from 100kHz to 1300MHz*
  • computer control for easier programming and monitoring operation
  • a micro USB computer interface
  • built-in SD/SDHC card reader for audio recording
  • higher 1st IF frequency 1705 MHz provides higher image rejections
  • CSV memory data capability for frequency uploads/ downloads and firmware updates
  • 2000 memory channels (50 channels X 40 banks)
  • alpha-numeric channel labels
  • offset reception and priority channel selection
  • auto-notch filter
  • noise reduction
  • voice inverter
  • discriminator output

Terminology Search & Scan

If this is your first time using a wide band receiver or you are not familiar with the terminology used, it is very important to understand the difference between SEARCH and SCAN modes.

SEARCH: The AR-DV1 provides several operations where transmissions (active frequencies) may be automatically located by sweeping the receiver over a wide frequency range, either from the currently displayed frequency traveling upwards (or downwards) in a specified tuning increment (step) or by sweeping over-and-over between two specified frequency limits. This process is known as SEARCHING.

As the name implies, this process can take a long time to find transmissions due to their ‘often intermittent’ and brief nature. For this reason, it is best to slice large frequency ranges into smaller, more manageable pieces where they may be intensely monitored. When examining large frequency segments, it is common to find that 90% of the frequencies are inactive and only a small number of the remaining constitute what you really want. Searching still remains the best way to initially locate active and interesting transmissions (in conjunction with a good frequency listing and band plan).

SCAN: Once active transmissions have been identified (either by searching or by using a good frequency guide), it is more efficient to store the data into memories which can be rapidly and automatically monitored in succession, stopping when activity is encountered. This is a much more efficient means of monitoring the most wanted frequencies as you have targeted 100% of what you most want to hear. By contrast, searching is very inefficient for day-to-day monitoring.

Note; For the search & scan functions to operate properly, it is very important to advance the squelch to cancel background noise. This is because the AR-DV1 believes that it has found an active frequency when the squelch opens and the «BUSY» indicator lights up. Advance the squelch control clockwise until the background noise is just cancelled; this is known as the «threshold» position. If the squelch control is advanced too far, weaker signals may be missed.
