I received the Draws on or about June 28. It performed flawlessly until a couple days ago. After using it till about midnight, I discovered that it was essentially dead the next morning. Draws-Manager said it could not be found. There was zero audio to my Ft818. The gps no longer functioned in gpsmon or cgps, including a myriad of other issues. Pi continued to perform fine. I hooked up the Signalink and was able to work as before. I vbelieve that the board has quit. I sent a message via the NW Digital site and no response. Please exchange this board for a working replacement. Please advise.
