Interesting idea. Have to test : 2 main potential issues : sample rate at 2MSymbols is not reliable with the current version ; Poor dynamic amplitude could disturb OFDM modulation.
Is this still utopic?
Need to make a special version to test 2048KHZ I/Q sending. But surely could be an interesting project. So it could maybe possible.
2048 kHz I/Q would also make it possible to modulate some low-resolution analog TV (about 128 pixels per line).
Any chance to have this special version 2048KHz I/Q?
I'm also interested. When you capture an IQ file from an existing DAB broadcast and replay, does this work? Has anyone already tried?
Tried last year (before I started this issue) but it doesn't work.

Would it be possible to send a raw file (for example from https://sdr.kt.agh.edu.pl/sdrdab-decoder/download.html ) to GPIO in order to get a Digital Audio Broadcasting stream at a given frequency (for instance 229,072 MHz)?
BW should be 1,7 MHz, Samples always are 2048 kHz.
