HF-One: HF-One MKII: Serial Port

On a Chinese website, I found this picture of what I think is the HF-One MKII. Looks like a serial port on the back of it. Also, I keep seeing references to "kits." No response from the seller yet, so don't start counting chickens before they are hatched.

And for Hans... is that a shielded banana plug, too?

SO-239 and 9-pin serial for the win!
