 Direct sampling SDR architecture in specific bands, without frequency conversion
AR-DV10 is a hand-held Software Defined Radio, the 100 KHz to 1300 MHz signals are converted to a super heterodyne 47.25 MHz intermediate frequency and then digitized with a A/D converter. AM and FM broadcast bands are digitized after direct convertion in I/Q format. Signals are then processed by an Altera Cyclone IV FPGA and an Analog Devices Blackfin DSP for demodulation. The DV10 revolutionary features such as multi-digital modes reception and auto-detection of digital modes have been made possible thanks to these latest processing technologies. Some of its outstanding features are the automatic detection of P25 / dPMR / DMR / NXDN / Digital-CR / D-STAR / Alinco / Yaesu modes; fast memory scan and program search; receiving support functions such as step-adjustment / offset / priority reception; MicroSD card support for recording / memory data / firmware updates; dedicated radio IC for 0.52-1710kHz AM and 64-108MHz FM broadcasts; IPX5 water resistant.

An useful function is the "STEP-ADJUST", when the array of desired receiver frequencies is not compatible with the default step frequency. Step-adjust allows setting the frequency steps accordingly. The following example describes a situation when a 20kHz frequency channels needs to be adjusted (offset) to 10kHz.
The step-adjust function on AR-DV10
Please note, the AR-DV10 is supplied with a flexible rubber antenna to be attached to the 50 Ohm BNC jack located on the top of the receiver. Due to physical limitations, the supplied flexible rubber antenna is not ideal for reception of LW, MW or SW frequencies. Although it does work to some extent, a dedicated external antenna should be connected for optimal reception of those bands.
- Firmware updates
On internet AOR site you can free download the firmware updates for AR-DV10. The "1807A 2018/07/13" firmware feature improvements as; better frequency accuracy through additional automatic temperature compensation by FPGA/CPU; better P25 and DMR decoding; better SD card compatibility for recordings; CTCSS, DCS, reverse tone, voice scramble user settings now displayed during reception.
- AR data editor
A convenient browser based memory data editor for the AR-DV1 and AR-DV10 receivers. The editor allow to load, edit and save your receiver's memory channel data. Create new frequency databases. File format conversion between AR-DV1 and AR-DV10. In other words, a frequency database of one receiver can be opened and saved into a format the other receiver can understand.
- COSPAS-SARSAT decoder
Optional COSPAS-SARSAT distress beacon decoder function was added (to enable this feature you need also to purchase an unlock key). Such beacon are activated by persons, aircrafts or vessels in distress. AR-DV10 is the world's first handheld radio receiver to feature this unique fuction. It allows to receive both the beacon's analog 121.5 MHz as well the digital 406 MHz signal which indicates the GPS location and ID of the beacon owner. The AR-DV10 can of-course display the GPS and ID details on its LCD.
- Earphone antenna
When the earphone antenna cable function is activated, the cable acts as an antenna for the FM Broadcast band (64-107.99999MHz). Earphone reception can be convenient when listening while on the move such as for example in the train where the flexible rubber antenna would not be convenient.
Scrambled analog voice transmissions can be decoded with the V.SCR function. The scrambler is sometimes used in public service radio, automobile racing and cordless telephones. This function is limited to FM mode with IF bandwidth of 6kHz and 15kHz. (not available in the USA consumer version).
- Signal's functions
Advanced setting give access to NXDN / D-CR scramble code, RAN (for NXDN mode), NAC (for P25 mode), color codes and slot selection (for DMR mode). CTCSS / DCS & reverse tone for analog mode: Continuous tone-coded squelch system (CTCSS) and Digital-code squelch (DCS) is a function which opens squelch only when a preset tone frequency is detected in the signal. Otherwise the audio will be muted. For reverse tone operation squelch reacts in the opposite way, that is the squelch "closes" when the designated tone is detected, and it remains open for all other tone frequencies (this system is used mainly in Japan).
The squelch function quiets the background radio noise when no signal is present. It operates in analog modes and the digital auto-mode. There are two types of analog squelch: NSQ (noise squelch) used for FM mode. LSQ (level squelch) used for AM, LSB, USB, CW modes. The receiver automatically selects the appropriate squelch type for optimal performance. However, if needed the squelch type can be forced to desidered setting.
Supplied accessories are the large capacity Lithium-ion battery pack, AC power adapter, alkaline battery tray, cigarette lighter DC/DC converter, fast charger cradle.
