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...
