Main

Copy All to the Clipboard

The entire contents of the screen display are copied into your clipboard. Useful if you wish to include a section of a decode from Rivet in an email or word processor document.

Load a WAV File

Rivet not only decodes audio directly from your radio but can also decode data contained in WAV files which were recorded previously. Note that Rivet can only decode WAV files which were recorded in mono mode and at certain sample rates (usually 8000 Hz).

Reset Decoding State

If this menu item is selected then Rivet resets to the default settings for the particular mode you have selected. So if Rivet has set its levels and symbol timing on a signal and this option is selected then Rivet will reset and try to reacquire levels and symbol timing.

Save the Current Settings

If you click on this all of the settings you have selected (Mode etc) will be saved in a file called "rivet_settings.xml". From then onwards when you restart Rivet the program will load these settings and use them as its default. To change this select the settings you would like to be your new default and click on this item again.

Save to File

When this option is enabled all traffic that is decoded by Rivet will also be saved to an ASCII text file. When you select this option a dialog box will appear requesting you give a name and a location for this file.

Save Bit Stream to File

When you enable this option the program will ask you to select a file name and folder for the file. Afterwards the raw binary output from the program will be a saved in that file (which has a .bsf prefix). It is then possible for you to analyse the data in this file for the purpose of reverse engineering a mode. Please note that this option only currently works when decoding selected modes.

Soundcard Input

When this is enabled Rivet will accept and attempt to decode audio from the audio source selected by your PCs mixer. I would recommend that you use your PCs Line Input source for this.

Exit

Use this to shut down the program.

Modes

Use this menu to select the mode you wish to decode.

Information on the modes decoded by Rivet

Options

Debug Mode

When this mode is enabled Rivet will display debugging and diagnostic information about the signal it is decoding. Unless you are a developer I wouldn't recommend you enable this option.

Invert

When enabled the data received by Rivet will be inverted. So for example if a FSK (Frequency Shift Keying) mode is being received and the high tone normally represents a 1 and a low tone a 0 , if this option is enabled then the high tone will represent a 0 and the low tone a 1. In some modes (e.g CCIR493-4) Rivet will automatically decide if Invert needs to be enabled or disabled and will change it accordingly.

Set the CROWD36 High Sync Tone

This option is used when you are in CROWD36 mode to tell Rivet the tone number of the high sync tone being used by the CROWD36 station you are monitoring.

View

View GW Free Channel Markers

If you are decoding the shore side of GW 100 baud FSK channel you will see a free channel marker decoded every few seconds. This will soon fill Rivets display and may become annoying. If you disable this option the program will ignore free channel markers and you will only see other traffic.
