Thank you to all that replied!
Hans, if you could add a table of contents item for “CAT” in the manual, that would be great.
I am going have a crack at remoting the QCX CAT commands via an ESP8266/Arduino combination using a Web Browser. My Web coding skills are not that good but will see if I can GET/POST commands to flow using coding examples from the ESPWiFI library. Getting audio to flow over an HTTP steam is beyond my ability at the present time ...
