[Elecraft] W1 dimensions and switch

[Ron D'Eau Claire]

The depth of the board depends upon the build options you use, Mike.

If you build it as shown in the manual, with the battery case and BNC jacks
on top, it's about 0.9" from the bottom of the board to the top of the
battery case (the battery sits down below the top of the case so it doesn't
add height). 

If you leave the battery case off, the height to the tops of the BNC jacks
is 0.95" including the heavy pins that extend through the pcb slightly. If
you cut the heavy pins on the jacks flush with the bottom of the board, the
height drops to about .75" Those pins are heavy and the instructions don't
suggest trimming them off. They aren't tall enough to pose an issue with the
feet mounted. 

If you mount the BNC jacks on the bottom of the board and leave the battery
holder off, you'll have to allow for the BNC connector height on the bottom
side and the height of C9 and C12 on the top side. C9 and C12 now become the
tallest parts on the top side at 0.6" (the data and power connectors are
slightly lower). 

If you put the battery holder on the bottom, you'll need to allow for its
height plus whether you mount the jacks on the top or only have to clear C9
and C1. If the battery holder is on the top, you'll need to allow 0.25" for
the mounting hardware on the bottom side of the board. 

Of course I'm assuming you don't use the feet. They are high enough to just
make the battery holder screws clear the desk top.  

For reference, the PCB dimensions on mine are 5.42" x 2.7" 

Those are typical dimensions taken from my assembled unit. Sizes of the PCB
may vary a bit by production run. The heights of the components may vary
slightly based on the components themselves and how close to the PCB you
mount them.

I am thinking about building a W1 into an enclosure, with the jacks and
switch mounted on the enclosure with wire connections to the board.

It looks like the switch is a simple DPDT switch, and anything would do,
yes?

Also, there is no specification for the approximate depth of the populated
board. Does any know that that is?

Thanks
