Re: A Solution To The Digital Mode Recognition Issue #Mode Recognition #mode

Where is the RS-ID system specified?

What is the process for allocating IDs for new modes?

Most are aware that mode identification became a necessity more than a decade ago as the number of sound card modes grew. The problem was solved early on thanks to the Reed Solomon Identifier developed by F6CTE. Yet here we are years later with more modes than ever before and we're still not using RS-ID when we should be.

It's puzzling because there are only a handful of modes that are discernible by sight and sound so we're left with dozens of variants and sub-modes that require RS-ID in order to be identified quickly and efficiently.

Prompt identification by observation is impossible because many variants share the same modem with their primary counterparts so their appearance is identical. We also have protocols that share the same modulation type which have visual and audible similarities that make it difficult to distinguish one from the other.

The solution would be to automate the process by having the TX-RSID engage by default whenever a difficult-to-decipher mode is selected. An easier approach for developers to implement might be to add a pop-up that reminds the user to engage the TX/RX ID when selecting certain modes.

It's not only bad practice not use mode ID when attempting to communicate with a protocol that's not easily recognized, it's a waste of time. It also sends the wrong message to new comers and it's certainly not the way to promote amateur radio to the public in a field day setting or at other public events.
