Perstel DR-201 at high indexes

Question

Hello!I'm having trouble with DR-201 DAB radio made by Personal Telecom. I'm trying to force it receive high quality sound (don't ask me how) and it seems that mentionel model can't receive neither audio nor DLS if subchannel size exceeds 168 capacity units (in Table 7 these are inedexes 47, 55, properly in those modes?I've seen that probably no one radio station broadcast at more that 192kbps, so maybe there are no experience. But I hope...
