1 INTRODUCTION
1-1 INTRODUCTION
Thank you for purchasing the AR-DV1 SDR Digital Voice Receiver.
AOR is pleased to present you with the AR-DV1, the FIR T software defined digital voice receiver to
receive and decode virtually ALL popular digital modes such as MOTOTRBO™, DMR™, dPMR™, APCO

WARNING: Modification of this device to receive cellular radiotelephone service signals is
prohibited under FCC rules and Federal law.

1-2 TAKING CARE OF OUR RECEIVER
There are no internal operator adjustments needed. In the unlikely event service is required; please
contact us for technical assistance.
Do not use or leave the receiver in direct sunlight. It is best to avoid locations where excessive heat,
humidity, dust, and vibrations are present. Always keep the AR-DV1 free from dust and moisture. Use a
soft, dry cloth to gently wipe the external surfaces clean; never use abrasive cleaners or organic solvents
which may damage certain parts.
Treat the AR-DV1 with care; avoid spilling liquids into the receiver and the associated power supply.
pecial care should be taken to avoid liquids from entering the area around the controls and through the
speaker grill or via the connection jacks.
The AR-DV1 is designed to operate from a good quality regulated DC power supply of 10.8 to
16.0 V, which should be capable of supplying 1 A. Never connect the AR-DV1 directly to an AC power
outlet.
The polarity of the DC input jack is clearly marked (center positive); the chassis of the receiver is at
negative ground.
SAFET NOTICE – Always disconnect the power supply from the AC outlet when the
receiver is not in use for a long period of time. If used mobile, note that the AR-DV1 has
NOT been manufactured or tested to meet any specific mobile safety requirements. The
AR-DV1 has no user adjustable internal parts.
When using the AR-DV1 as a base station, the best short wave reception is usually achieved through the
use of a separate external earth (or ground) rod. However, consider the implications carefully if your AC
building supply uses a Protective Multiple Earth (PME) system. If in doubt, consult a qualified electrician.
Never earth (ground) to a gas pipe! The antenna connector of the AR-DV1 is intended for connection to a
50 Ohm (unbalanced) coaxial fed antenna such as a discone, dipole, Yagi, etc.
Avoid power cables when installing an antenna.
Operating anomalies
hould the AR-DV1 appear to behave strangely, normal operations may be easily achieved by performing
the following steps:
Symptom: No control of the receiver or the display appears to be frozen
Action: Turn off the power switch on the front panel. Leave it off for approximately 10 seconds.
Turn the power switch back on again. Normal operation should be restored.
hould the receiver still behave strangely, try a RE ET as explained in chapter 11-5.

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. earching 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.
