Code300-32 - Audio Input

Code300-32 Standard

Code300-32 Standard can handle up to two audio channels simultaneously, i.e. you can connect two receivers to the LINE IN input; one on the right channel (R) and the other on the left channel (L). When running the decoder, the required input channel can be selected from either the control panel and from any analysis/decoding tool. All the operations can be performed simultaneously even when using many tools at the same time.
A few examples :
  • Left channel Baudot, Right channel Sitor
  • Left channel MIL188-110 Serial and MIL188-141A ALE, Right channel Sitor and CW
  • Left channel Stanag 4285 and Phase Constellation, Right channel Baudot, Oscilloscope and Bit Analysis
Single Receiver Configuration
Single receiver configuration
Only a single (default Left) channel will be used i.e. Left channel or the MIC input

Twin Receiver Configuration
Two receivers configuration
Left channel (L) for the first receiver and Right channel (R) for the second receiver


Code300-32 Extended

Code300-32 Extended allows the running of two sessions of the program at the same time. This means that with two audio cards the system can handle up to 4 audio channels simultaneously: One could have two receivers, one into the Right (R) channel and the other into the Left (L) channel of the LINE IN input socket of the first audio card and the same configuration for the second audio card.
Running the decoder, the input channel can be selected from both the control panel and from any of the analysis/decoding tools. All the operations can be performed simultaneously even when using many tools at the same time. A few examples :
  • Audio card 1: Left channel Baudot and Right channel Sitor
    Audio card 2: Left channel HFDL and Right channel MIL188-110 39 Tones
  • Audio card 1: Left channel MIL188-110 Serial and MIL188-141A (ALE), Right channel Stanag 4285
    Audio card 2: Left channel SKYFAX and MIL188-141A (ALE), Right channel Coquelet 8 and CW
  • Audio card 1: Left channel Pactor II, Right channel Pactor II
    Audio card 2: Left channel Pactor II, Right channel Pactor II
    (in this way we can follow the entire traffic of two different networks).
Code300-32 Extended can run two completely independent sessions of the same decoding mode, this unique characteristic can be utilised on approximately 20 different modes.
For example, you can open two sessions of the MIL188-110 decoding mode receiving a station with two different receivers/aerials (tuned on the same frequency) thus utilizing space or polarisation diversity.
Or you can follow a network using the same mode on two different frequencies exactly like having two different decoders. You can use up to 8 different decoding modes at the same time on both channels.
In the Extended version you can open two simultaneous independent sessions of the following modes.

ARQE ARQ IRA ASCII Baudot CW*
FLEX GMDSS HFDL Mil 188-110 serial Mil 188-110 39 tone
Mil 188-141 ALE Pactor I Pactor II Packet POCSAG
PSK31 Sitor STANAG 4285 STANAG 4529 Skyfax
* note: you can also open two CW sessions in the Standard version

4 Receiver Configuration
4 Receivers configuration
Two receivers are connected to the first audio card (left and right channels of the LINE IN). Two receivers are connected to the second audio card with the same configuration.

Second audio card

Should you find any problem installing a second audio card inside your PC or you are using a notebook, the easiest solution is to use an external USB audio card. According to our laboratory tests the Sound Blaster MP3+ has been found to be one of the best external audio cards. Under Windows 2000 and XP (Home or Professional), the card will be recognized as a generic USB Audio Driver by the OS without any further need to load the drivers supplied with the card. (MP3+ is not in anyway related to the MP3 audio standard!)
