Build Your Own Morse Keys and CW Paddles
Find schematics, construction guides, and creative ideas for building various Morse code keys and paddles.
Morse keys are fundamental tools for amateur radio operators who enjoy CW, allowing them to send messages using Morse code. Many hams find satisfaction in building their own keys, tailoring them to personal preference for feel and operation. This hands-on approach to equipment often results in unique designs, from simple straight keys to advanced iambic paddles, all crafted to ensure precise and comfortable sending during QSOs.
This category showcases a variety of homebrew Morse key projects, offering construction details for operators looking to build their own. You'll find designs for single-lever and iambic paddles, often utilizing common materials like PCB or even repurposed household items, as seen in the "Poor man's paddle" and "Five Cent CW key" projects. Additionally, there are resources for building associated electronics, such as simple iambic keyer circuits, which enhance the functionality of these custom-built keys for everyday amateur radio activity.

This thoughtful review details ajourney from the stock Elecraft KXPD2 paddle to an innovative pressure-sensor alternative. The author candidly describes issues with their original paddle—intermittent operation and loosening screws—before discovering VK3IL's pressure-sensitive design through QST magazine. The construction process, using a PCB and components generously shared by the designer, proved straightforward despite challenging SMD soldering. What stands out is the clever DIY housing solution: a "sandwich" of closed-cell foam encased in heat-shrink tubing that fits comfortably in hand. The ergonomic design allows effective single-handed operation for portable SOTA activations. The successful implementation has rendered the original paddle obsolete, leaving only the task of covering the radio's paddle port. -

The Pressure Paddle V2.0 simplifies the original 2019 design by using MOSFETs’ unique properties for reliable, minimalistic switching. When pressure sensors detect a press, they reduce resistance, activating the MOSFET and lowering voltage until it stabilizes at the MOSFET’s threshold. This ensures consistent “key down” signals for the transceiver. Compatible with 3-5V logic systems, the circuit operates independently of pull-up resistor size. The PCB is lightweight, easy to assemble, and can be packaged in heat shrink or mounted. This version maintains durability with fewer components and flexible packaging options. -
