Today I implemented the remote station on the CRX phone application (https://m.crx.cloud).
It works well i made few QSO’s in UHF with the remote station, with control in a browser and sound via MUMBLE.
73 to all,
PS: I am using a CHROME WEB browser, and a RASPBERRY PI.
For people who want to test, you have to configure first your remote station on PC website (https://ham.crx.cloud).
