New Tecsun PL-880 On Its Way?

Thanks, Owl:

Tecsun PL880 on its way?

There have been pictures which seems to be from the brochure of this model around for a few days:

Today someone who has close connection with Tecsun posted a few photos of a radio matching the brochure:

It is claimed the AM section of this new model adopts an architecture similar to ATS909X, i.e. dual conversion to 2nd IF of 450 KHz which is then inputted as RF signal into Si4734/5 and further downcoverted to the IC's "low IF" for DSP decoding.

Also, the 18650 Li-on rechargeable batteries are used in this model.

Additional features incudes separate LSB/USB and 10Hz step for SSB (implies dual PLL?).

No mention of Sync. detection though (a trade-off for DSP I guess).

Just received some more details:

there are four (2.3/3.5/5.0/9.0) AM bandwidths and five (0.5/1.2/2.3/3.0/4.0) SSB bandwidths. Surely this is a huge improvement over ATS909X which makes no use at all of the seven IF bandwidth provided by Si4735.

I am curious how the multiple SSB bandwidths are implemented.

2nd BBS link is already gone. Hope this isn't vaporware-looks awfully nice.
