Control your computer with Morse code
Full access to your keyboard
CW Pulsar interprets Morse code and types on your computer as if you're using a normal keyboard. But it's not limited to just letters and numbers. Keying simple, memorable command sequences lets you reach every key of a standard tenkeyless keyboard.
Need to press left arrow? That's L + command. Home? LL + command. Need a capital letter? S + command for shift, then type your letter. Ctrl+Alt+Delete? C + command, A + command, D + command.
No drivers, no software
CW Pulsar identifies as a standard USB Human Interface Device keyboard. To your computer, it is indistinguishable from any other common USB keyboard.
This means you don't need to look for drivers or download any special software to use your CW Pulsar. Plug it in and it's ready to type whether you're on Linux, macOS, or Windows.
Works with your preferred key
Whether you use iambic paddles, a single paddle, a straight key, or even a classic bug, your CW Pulsar can interpret your keying.
No standalone electronic keyer is required for paddles. Just plug in your key and start sending.
A 3.5mm jack, quarter-inch jack, and bare terminal bank are provided to easily connect any key, or even multiple keys at once.
Adjusts to your keying style
Whether you're learning Morse or you're an experienced operator with a diamond fist, your CW Pulsar can be configured with just two sliders to fit your preferences.
Keying WPM and spacing are each adjustable to match any keying style from the strictest standard Morse to sloppy keying with extra-long Farnsworth spacing.
Easy cable management
Plugging and unplugging your preferred key is tedious, especially since most amateur radios now have their key ports on the back. Your CW Pulsar can pass your keying inputs through to your radio with a 3.5mm jumper cable. Just flip the pass-through switch.
To keep your desk tidy and manageable, all cables come out the back and all controls are on the front.
Assembled or mailable as a QSL card
An assembled CW Pulsar comes ready to work out of the box and has a stamped metal case that will look nice next to all your MFJ instruments.
If you enjoy kits or want to design your own case, or you're just on a budget, a through-hole board with the same schematic is available as an inexpensive, mailable QSL card. You can purchase one for yourself, or purchase a stack to share with contacts and clubs.
Open source, open hardware
The CW Pulsar's schematic, bill of materials, and source code are all thoroughly documented and freely available.
If you prefer a project over an assembled device, you're encouraged to tinker, mod, and build whatever you like.
Morse for accessibility
A CW Pulsar can be an effective assistive technology for people who have difficulty using a standard keyboard. It can interpret Morse code from anything that can close a circuit, not just traditional Morse keys.
We believe computing should be accessible to all. If a CW Pulsar would help you access your computer more easily and the price is a barrier, contact support@cwpulsar.com and a device will be provided at cost.
