SiLab's datasheet for the new series "wheel tuned" DSP IC used in this Tecsun radio has been available since about the first of the year. I don't see anything on it that changes the AM or FM performance from the older SiLab IC used in the current ULR DSP radios like the PL-380. And there is no provision for LF reception. It seems to be optimized for low cost mass-produced radios. And despite the nice "2010" name (remisniscent of the good Sony 2010 receiver), there is no provision for an AM sync detector or SSB.
