Sverre Holm writes: Here’s an adapter that emulates both a single-lever paddle mode and the ultimatic mode. It is meant to go between a dual-lever paddle and an iambic keyer. The adapter has been implemented in an AVR Butterfly in C and it is compatible with Morse keyers such as the one in the Elecraft […]
Marcello posted picture of his free Iambic Keyer PCB build, a guest PCB from Andy Palm/N1KSN If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer.
43oh, a forum dedicated to the MSP430 microcontroller, hosts a design contest. Last month we gave free PCB coupons to the winners. The winners also let us host their boards in the free PCB drawer. This board is an iambic keyer: On the heels of Rob’s Iambic Keyer comes N1KSN’s keyer. An iambic keyer is […]
Rob K1WAW was trying to sharpen his Morse code skills and wanted to use an Iambic Keyer. He built this prototype which connects the left and right paddle of the telegraph key to pins on the MSP430 Launchpad, which is programmed to produce the dot/dashes and output it to a speaker at an audio tone […]
