Section 3. Baud Rate Summary Table

Below is a table of expected baud rates you can most likely encounter for the latest listing of modes available. An accurate baud rate is a valuable tool to identifying a particular mode and there are many modes that have unique baud rates. As of this writing the Hoka and Wavecom units seem to have the most accurate capability of all existing decoders currently on the market.

All rates are in units baud except where marked b/s - bits per second.

A few baud oddities of note:

  * 128.5bd ARQ-M2 French Forces circuit between Papeete, Tahiti and Mururoa.
  * 184.6bd ARQ-E French Forces circuit used by RFFXQA Sarajevo, BIH
  * 384bd FEC-A used by MFA Paris,F and French Emb., ROU
  * 109.3bd SITOR-B used by an unidentified user.
