ACC port operational philosophy with DIGIU

So, I got my cable built for the ACC connector last night. I'm using a SignaLink USB, looks like I need to move JP3 to get enough output.

One thing I noticed is that the mic is still hot when using the ACC connector. In digital modes, this is Not Good. The workaround for this would be to switch to Line for the mic input, but without persistance in the mode settings, this is kludgy at the moment.

I understand that it was done this way for voice keyers, and that makes sense, but with DIGU, it really doesn't. Also, when muting the speakers, (I really don't want to listen to PSK31 screaming at me ) it mutes the ACC output. I think the speaker mute shouldn't mute the ACC port when on DIGU.

The way it's supposed to work is this:

If you select ACC from the drop down selector, it should mute the microphone inputs. If you select MIC, BAL or LINE, you can have the accessory input mixed in by selecting the +ACC button to the right of the audio level slider.

The idea was to allow people to use the accessory input for voice keyers, or digital modes and have both mixed or muted mic signals.

Now, I have not tested this myself to verify it actually works this way, but that was the way it was supposed to be configured.

Testing this is on my TO-DO list, but probably won't happen until the weekend or next week.

Ultimately, we will have DAX working and these problems will no longer be an issue.

With regards to the speaker muting, unfortunately, there's nothing that can be done about this. The accessory output and the speaker output are fed from the same hardware point, so muting one would mute both. Again, DAX will fix this problem.

DAX is currently on the Version 1.1 roadmap.
