Many thanks to SWLing Post contributor, Ivan, who shares the following:
In December, sales of this radio will begin. The seller promises to put the price of 60 US dollars. Radio of a level not lower than Tecsun PL-660 for such a small price is great! There is a video review on YouTube. Unfortunately in Russian. There is no more information on this radio on the Internet. I myself found out by accident.

Thank you for the tip, Ivan! I’m guessing this is yet another portable based on the Silicon Labs SL4735.
The display looks like that of the Digitech AR-1780 and the keypad configuration is nearly identical–the only visible difference being the shape of the SSB button which is rectangular on the AR01780.

The Digitech AR-1780 keypad.

The XHDATA D-808 Keypad.
The power buttons are also in different locations.
AliExpress has the D-808 in their catalog, but the price is listed at $2,000 per unit (!!!) with no shipping to the US. Perhaps the pricing formula changes if you place an order within Russia?
Again, thanks for the tip, Ivan!
Post readers: If you have the XHDATA D-808, I’d certainly welcome a review. Please feel free to contact me about submitting one.
