I'll take a quick look tomorrow.

The RX888 actually doesn't have an API DLL or library as such, just a mass of code.

Ah,

 

Well, the RX888 and RX888 MkII are supported. From the API I think they're the same thing..

Just to make clear, what I was talking about in my starter post:

Other than the RX888 the RX-888 MKII has a digital attenuator (PE4312) only for HF and a VGA (AD8370 [the RX888 has a fixed LNA!]) for both HF and VHF.
That means, the attenuation/amplification range of the RX-888 MKII is from -41,5 dB to +33 dB for HF and from 0 dB to +55 dB for VHF (as Jinze Peng wrote).

I don't know what the driver API allows for the RX888 and the RX-888 MKII, but for a fully supported RX-888 MKII I would expect:
1. Slider for attenuation -31,5...0 dB for HF only
2. Slider for gain -10...+33 dB (?) for HF and VHF (or even extended range, if the R828D allows additional gain stages!)
3. 2 checkboxes for HF- and VHF-Bias-T on/off
