Specs or Data on Audio Output from ACCY port (Menu Item 33)

[Richard Kriss]

I could use some help the Kenwood specifications on the digital output
coming out of the 13-Pin ACCY plug on the TS-570. This is the audio output
Menu item 33 that has three options 0, 1 and 2.

I  have heard the industry standard is 0.5 VRMS to 1.0 VRMS and I have no
way to know what's coming out of the TS-570.

Does anyone know the Kenwood specifications for the audio output?

Has anyone measured the outputs of settings 0, 1 and 3?
