Although the adverts say "no radio", nothing prevents one to configure the audio-chip and pll for radio reception. In fact, two near mono channels can be listened concurrently ! There are nice "example telegrams" somewhere in the end of the spec, adding appropriate writes to msp_autodetect() at the end of the driver should be straightforward. Conveniently the 'autodetect' command is just the same between 34xxD and 34xxG. Looks like it is not enough. I'd start by adding a msp_write(bktr, 0x10, 0x0030, ???) into the MODUS, with appropriate bits to give precedence for US broadcasts, there's a table in the spec; and another to FM-PRESCALE, setting it to the max. Note that modus must be written before auto-detect command. NICAM reception here had a similar quirk, it was receiving okay, but the level was so low it was totally unaudible. 7Fh into NICAM-PRESCALE did the trick.
