Given the best thing on TV is the dust and the rate at which MW transmission are disappearing, I'm quietly contemplating the following:-
1. In-Car DAB/DAB+ adapter with in-built FM transmitter (Made by Pure I believe)
2. OSMC with touchscreen on Raspberry Pi (3?, the one with on-board WiFi/Bluetooth?) hooked up to a USB HDD with our favorite music 'backed up'
3. Sstran AMT3000
All plumbed in/switched accordingly, housed in a nice enclosure, about the size of a set top box with linear PSU ...
Making it look good for in the home & not something dragged from the lab, there's the challenge ...
This way, we'd have a wealth of content to wire to our, well, wireless's ... Including my underused FM Troughline.
