CW Hotline Box

thingiverse

The folks at Ham Radio Solutions (https://hamradio.solutions/cwhotline/) have come out with a really cool inexpensive device to allow one to communicate with Morse Code (CW) over the internet. This is a great way for beginner hams to learn the code and more experienced hams to polish their skills. The device is called the CW Hotline and comes in a kit form. Soldering the components onto the printed circuit board is quite easy if you have basic soldering skills. The kit also provides a plastic box to house the circuit board and the builder must drill several holes to accommodate the three jacks, 2 LEDs, a switch, a notch for the key, and a slot for the USB connection. Drilling the holes is a fairly simple task however some builders have found that to be somewhat intimidating. I designed this box as an alternative to the box provided in the kit. The CW Hotline can be assembled with either a straight key or a set of paddles (your choice) and one of the files has a notch for the key/paddles to protrude out from the circuit board. If you prefer to use your own key or paddles and plug them into the provided jack, there is an STL file to print the box without the notch. The plastic bottom that comes with the box included in the kit will snap into the 3D printed box. In order for the components to line up with the holes in this box the 3 jacks should be soldered snug to the circuit board. Adjust the height of the LED’s and the switch and test fit the board into the box before soldering them in place.
