It is an odd device, DaveRo, it's tuned in via my laptop, and has 4 stations, one on each side, just turn it over to change stations, tilt back or forth to adjust the volume, and on it's face to switch off. No knobs, and only an on/off switch on the back. Nothing for the grandchildren to readjust or fiddle with.
I'm wary of tinkering with it in case I lose it all together.
I get my night time radio from the TV in the bedroom, which is on freesat. The people who installed that found a tiny gap in the hills to point the dish at.
