Code3 Gold
The monitoring tool used by professionals
Software for DOS, Windows 95 and Windows 98 -
last release avilable v 1.61
This has got to be the hottest VHF and Shortwave decoder to hit the
streets. Over a year of hard development work over at our Netherlands HQ
has resulted in this latest decoder product.
Code3 Gold uses the very best of software DSP filtering and detection
technology (borrowed from our professional Code30) and the very latest
surface mount miniaturized electronics for the hardware interface. The
performance is stunning, the compactness remarkable and the price is
simply unbelievable! (but still unanounced)
Stunning performance
Anyone used to using our professional package, Code30, will be
amazed at how we managed to achieve such high performance from so little
hardware. The method we use is identical that used with Code30.
Hoka Electronics is unique in the decoder market to put all the DSP
software into PC compatible software code. This makes it much easier to
fully interlace the DSP filters with the software signal detectors and
system decoders making on-the-fly adjustments to the shift or baudspeed
completely seamless to the decoding process.
From the initial analog to digital conversion using the latest SMD
hardware, everything else from the roofing filter, the FSK detector, to
the post detection filters are all done on your PC!
All optimised for every possible combination of keying speed and
bandwidth. All of this filtering means your receiver does not need to
have expensive additional narrow filters for RTTY.
Simply use your wideband SSB setting for Shortwave monitoring and AM or
FM for VHF.
Versatile interface design
Regardless of whether you have a 9 way or 25 way serial port
connector, the Code3 Gold interface is simply plugged in without any
need for an adaptor.

AD Micro LF5
Cleverly constructed from a fully RFI/EMI screened standard 9 way to 25
way adaptor case, both 9 and 25 pin plugs are connected internally and
therefore available for use.
All 4 COM ports, 1 to 4, are all supported.
No power supply needed
All of the interface's modest power requirements are supplied from
the PC using the serial port itself. In fact, there is more than enough
power available - even when using a laptop.
No Copy Protection!
That's, right! No copy protection. For the first time ever for Hoka
Electronics we offer our Code3 software without any software copy
protection at all. You can install the software on as many PC's as you
like. The interface now includes its own special hardware security
dongle making the usage of our software much more flexible and
straightforward.
Automatic analysis and detection for shortwave systems
After the press of just one key [F1], Code3 Gold really starts pulling
its weight. After bringing up a simplified spectrum analyzer screen
showing the system's shift and baud speed, all you have to do next is
press the [enter] key. Code3 Gold does the rest for you.
If it is a system installed in your version of Code3 Gold, it will
immediately jump to that decoding module and lock into the system. If
the system you are listening to is not supplied with your software, it
will simply tell you the system name.

PC Requirements
Any modern IBM PC clone with a 386DX40 (or better) processor
although a 486 is highly recommended. MSDOS v3.2 or later, with at least
640k free DOS memory and a spare serial port (COM's 1 to 4 supported).

95 in DOS box and full screen. The only down side is that you need the
power of a Pentium to be able do it successfully!

ACARS
For VHF Scanner enthusiasts, one of the most annoying features of modern
life is the recent introduction of data to many VHF frequencies.
Aircraft followers have enjoyed listening to aircraft giving their
positional reports and allowing listeners on the ground to plot the
pilot's flying route from the comfort of their armchair. But a new
threat has arrived in the form of ACARS. This 2400 bps data system has
been around for some years but only recently has it really increased in
popularity with airline companies. Air traffic control centres no longer
need to speak by voice to pilots. The pilots can communicate directly
with the ATC computers thus alleviating the radio congestion of the
normal ATC frequencies. Code3 Gold allows you to regain the edge. Watch
the pilots send positional data about their aircraft, see engineers'
reports on aircraft engine performance, fuel levels, oil pressures,
special passenger requirements (such as wheel chairs or VIP treatment)
and lots more.
POCSAG
By far the most popular paging system here and in in Europe. Watch the
messages being sent to bleepers, read the messages. Open your eyes to
the fascinating world of numeric and alphanumeric pagers.
DTMF
Anyone with a modern telephone has heard this system. Used on many
VHF channels to dial numbers, access voicemail or remotely control
answerphones. PLUS, If you've heard these tones on HF Aircraft bands,
you'll now be able to decode their 'selcal' systems used by transoceanic
flights.
PACKET
Amateur radio operators use this system to interconnect computers on
VHF and UHF. 300 bps is used on shortwave, 1200 bps on VHF/UHF.
BAUDOT
This is used all over the world by Russian Maritime fleets, Military,
Press, Diplomatic and Utility stations. All baud speeds and shifts.
ASCII
Mainly used by amateurs, but some Diplomatic and Utility usage.
SITOR
The mode used by ships for sending telegrams and telex calls on
shortwave. Also used by Coast stations to send maritime navigational
safety messages (NAVTEX), Diplomatic and Utility stations.
PACTOR
100/200bps packet like data system mainly used by amateurs but also
by the Swiss Red Cross and United Nations for their links into the
world's trouble spots.
FAX
Used by meteorological stations to send weather charts and satellite
pictures. On VHF polar orbiting and some geostationary satellites (e.g.
Meteosat) use a special 2400Hz modulated tone system. This special "AM"
mode is also fully supported by Code3 Gold.
SSTV
Code3 Gold supports Martin 1 in full colour if you have a video card
that is based on the Tseng ET4000 chipset.
Standard Version
Optional systems If you want to really catch ALL the action on shortwave,
you need the "Standard Version". Watch Diplomatic stations, Customs,
Police, Military, decode weather stations sending 5 figure groups and
many more unusual stations. This adds nearly every decodeable system
there is to find on shortwave.

FAQ
Who use all these strange systems on shortwave?
Besides the usage of simple systems, such as SITOR and RTTY the
Australian, Dutch, Danish, Norwegian, Spanish and Pakistani Diplomatic
services also use Twinplex. The French Diplomatic also use ARQ6-70,
ARQ6-90 and ARQ6-98, the Italian and Polish Diplomatic services also use
POL-ARQ, the Algerian Diplomatic Corps use Coquelet and the Rumanian
Diplomatic Corps use ROU-FEC and Autospec. Interested in the military
action going on in the world's trouble spots? Then without Code 3 Gold,
you're still missing out! The Swiss Red Cross and UN Peace keeping
Forces use non-standard, modified PACTOR units which unlike the normal
Amateur PACTOR TNC units, Code3 Gold has no problems in decoding.
Belgian UN Forces are using Coquelet13. Only one or two of the above
systems are available on hardware only units - just think of all the
action you are potentially missing!
But all military RTTY is encrypted
No! It is not ALL encrypted. This is the biggest misconception. If
you're dedicated to monitoring these systems, then you will quickly
realise some of the best catches are to be found on these 'stranger'
systems. Find out what is happening in the world long before the
National news service do!
So what can Code3 Gold NOT do! ?
Despite the much wider number of systems decodeable with Code3 Gold,
there are obviously some systems that are designed so that even with the
right decryption equipment it is undecodeable without the right "key".
Also for deeper Bit Analysis and a wider range of demodulators you'll
need our even more powerful unit that Code3 Gold Professional or
Code30-A. For more details see the decoder compare table.
What about after sales service ?
Anytime up to 1 year after purchase you can request a free update to
the latest version of the software. The Guarantee lasts a full year too,
and this applies to both the disc becoming damaged or the hardware
failing in some way.
If, at a later stage, you want to upgrade to our Code30-A product we can
even give you a very attractive upgrade offer that means your money has
been well invested. |
