automatic with opening/closing the audio device on the USB host (Linux

Tuning cnanot yet be done via USB but has to be done on the UART.

> tuner.init!


> tuner.freq=88300000

can be used interactively on a mini embedded command line.

The RF guys should now be able to validate that the spectrum of the
device is clean and thus authorize the production of the first batch of
100 units.  With some luck, they will be available at OsmoDevCon !
