ARLA/CLUSTER: AOR DV1 - O derradeiro receptor digital de 100 a 1300 MHz.

Ham Radio - The Ultimate Digital Receiver, the AOR D-V-1

Listening around the radio spectrum nowadays especially the V.H.F. and
U.H.F. bands there is a huge amount of digital signals which the radio
listener is unable resolve because of the lack of suitable Digital
receiving equipment, available on today's market place.

You now have a solution to that great problem with the introduction of the
ground breaking *A.O.R.D-V-1* scanning receiver, the first integrated
digital voice receiver which allows monitoring of all the popular digital
voice modes, including D-star and D.M.R. You now do not need to use a pc
and decoding programmes, the A.O.R. has solved that problem, although the
receiver still has a output socket to use with other decoding programmes
for A.C.A.R.S and A.P.R.S for example.

Many radio listeners have used software and traditional scanning receivers
suitably modified with taps added internally to allow an output to a
computer for digital listening.

There have been several updates for the D-V-1 since the receiver was
launched to clear up some of the bugs present on the initial batch of
receivers, a great benefit to the listener, a simple firmware download
which fixes the issues and the A.O.R. D-V-1 will be updated with the
ability to resolve new modes,including TETRA.

There are receivers that continue all the way up to 3 Gigahertz, however
the A.O.R. stops at 1.3 Gigahertz, enough spectrum for you to resolve 23
centimetres transmissions. There are not many voice transmissions above
this range. Having capabilities to listen to digital transmissions below
1.3 Gigahertz is going to give you a lot of interesting services to listen
to if you have are restricted to resolving analogue signals only.

The A.O.R. D-V-1 is light grey in colour, measuring 178 x 50 x 215 mm,
making it a compact rig for desk or mobile use. It requires 10.8 to 16
volts, an A.C. adapter is supplied. It draws about.750 amps at 12 volts.

A micro USB socket is provided on the front panel for a SD or S.D.H.C.
card, folding feet allow a good reviewing angle.

Frequency coverage is from 100 Kilohertz to 1.3 Gigahertz. All popular
digital modes including MOTOTRBO, D.M.R.,D.P.M.R.,A-P-C-O P-25, N.X.D.N.
and I-COM D-STAR, Amplitude modulation wide and narrow FM, CW upper and
lower side-band.

Easy firmware updates via SD or S.D.H.C. memory card
200 memory channels 40 banks, contain 50 channels
Alfa numeric channel label capability for naming the frequencies.
Off set reception for repeater operation and priority selection
Auto notch filter
Noise reduction control
Voice inverter

C.T.C.S.S. and D.C.S tone capability a must nowadays with operators using
the same channel in nearby locations.

3 V.F.O.s are provided two for scanning a portion of a band, for example
430 Megahertz to 440 Megahertz.

Keypad backlight colour can be changed.

Tuning steps: - 10 50 100 500 Hz 1 2 5 6.25

7.5 8.33 9 10 12.5 15 20 25 30 50 100 500 Kilohertz.

I found the A.O.R. D-V-1 to be very sensitive and selective throughout its
range. I am using a long wire and a frame aerial for long wave and medium
wave bands. The dis-cone aerial is adequate for VHF and UHF, if you are
near to transmitters but resonant aerials work much better and allow
distant stations to be received.
