Bob,
I think you have it figured out.
The 5 pin cable goes on the end of the 16 pin connector that's nearest the 7805 regulator.
They only build one version of the raduino, one that plugs into a uBitx.
So all raduinos now have the 16 right angle header pins on the bottom.
Back when hfsignals only sold the Bitx40, it had a 5 pin connector on the end near the 7805 regulator,
leaving 11 unused holes in that row of 16.
Another change is that the Nano is socketed, so easy to swap out if you blow an IO cell.
However, if you buy a replacement Nano, be sure to get one that does not yet have the?
header pins soldered in place, because they must be installed on the "wrong" side of the board.
The only other change to the raduino is that they all come with uBitx firmware (I believe).
You will likely have to flash it with Bitx40 firmware.
There have been no board layout changes to the raduino
since it first came out in late 2016.

Just got the BITX40 today. I had the uBitx before and sold it to
a man who wanted to run digital. It was a dream to put together,
no problem whatsoever.
But the picture on the wire-up page for the BITX40 does not
show the same thing for the Raduino that I got today. I do not
want to assume too much but it seems the 5-pin connector
plugs into the 16-pin connector but it's not clear if it's to be
put in on one or the other end. The 16-pin connector is
labeled P3. Off to one end of the board is U3 which is a
3-pin regulator, it seems. I think I know where the 5-pin
connector goes but want to make sure...
