Thank you ve6ngk, DVSM is now working great in WT Mode, and parrot test audio sounds great.
I see now that Steve N4IRS posted about this in Aug. '22 - DVSwitch Mobile 2.x beta test available And DVSM also has a Node Mode where it will act as a node ie. an actual ASL node with its own node#! Pretty impressive for an android app! I will be looking into that further also.
And to W8WJB, documentation on the WT protocol and registration API would be great. Always good to have things properly documented somewhere. I hereby move that the ASL admins give you wiki access. Thanks & 73, David
