FLEX vs FLEX_NEXT issues #217

Open ramonsmits opened 2 months ago

ramonsmits commented 2 months ago

I've been testing 1.3.1 and in my setup I now enabled both FLEX and FLEX_NEXT demodulators on the same feed. In the past FLEX_NEXT felt unstable so I used FLEX.

During these tests I noticed the following:

  1. FLEX_NEXT messages often have corruption at the end
  2. Sometimes there is a different in the message
  3. FLEX_NEXT decodes a lot more messages
  4. FLEX occasionally decodes a message that FLEX_NEXT does not

FLEX_NEXT messages often have corruption at the end

very quickly saw that the text message that are decoded often show corruption for FLEX_NEXT at the end, some examples:

FLEX_NEXT decodes a lot more messages

Second, on the other hand... FLEX_NEXT often shows messages that FLEX does not decode:

FLEX occasionally decodes a message that FLEX_NEXT does not

And.. third, a very few times FLEX only decodes a message:

@jkctech @Forst @rfarley3 @boerviltje which version is stable for you? It seems that maybe an even older flex decoder was working better that the current in 1.3.1?

Does any of you have recommendations on how to debug/diagnose this? How do I both capture audio and also the multimon output? I'm a pretty experienced programmer but I don't know where to start with any of this.

EliasOenal commented 2 months ago

Piping through tee should work to save a copy of the input and/or output. I'm happy to merge improvements to the FLEX decoders.
