Hi Dave,
<<< Thanks for the great information as always. I assume you saw this data as well?
No, this is the first time I've seen that file, which seems to be SiLabs' promotional material for selling the Si4736 and Si4737 chips. Thanks for posting the link.
I'm still reviewing the detailed SiLabs technical document (linked by Paul, "P A Texnote") giving the full details on this new Si4736 DSP chip (as well as the Si4737, 4738, 4739) posted at

Hello Gary,
Thanks for the great information as always. I assume you saw this data as well?
Perhaps we will see RDS included soon as well.
Best wishes to all and good DX for 2015.

Hi Stan (and all),
<<< My understanding is that the Skywave is a custom build for CCrane. >>>
That is correct, Stan. Full disassembly here indicates that the CC Skywave is custom built for C. Crane by the Redsun Company in China, with both the RF and Digital circuit boards stamped with the C.Crane name and revision number. There doesn't appear to be any comparable radio currently for sale by any other company, including Redsun itself.
The CC Skywave is also the first Ultralight radio found to be using the new Si4736 DSP chip, which apparently solves both the heterodyne and "soft mute" issues.

My understanding is that the Skywave is a custom build for CCrane.
