K3 Data-A PSK31

[Trevor Smithers]

What are the benefits of using Data-A mode for psk31 as opposed to standard USB.
The manual p29, mentions that DATA mode offers several benefits not available in SSB modes however
other than automatically setting CMP to 0, I can't see much else happening.
Does Data-A route the signal differently to standard SSB for instance.

What am I missing?

Rig: K3
Interface: Microham DigiKeyer
Software: HRD/DM780

You can select the back sockets for the audio input for that mode, with a separate mic gain setting, so you don't have to keep swapping the mic cable over. At the moment you have to change the mic input manually, but I think one of the things on the list is that it will remember the setting.

You can also have different filter settings for data, e.g. a different center frequency.

This is great. The TS-2000, which is widely used by WSJT enthusiasts on VHF,
doesn't have this capability, as it has no special "DATA" mode or any other
way of memorizing all these configurational differences. You have to manually
change all this stuff ( six or so settings) every time you go from WSJT to SSB
to WSJT again.

I'm really looking forward to getting my K3 for so MANY reasons! Now here is
another one I didn't know about... April can't come soon enough!

A feature to remember the MIC SEL source by mode is in the firmware now
being tested by the field test team.
