I made a screen recording of a qso to demonstrate the serial interface between keyer / decoder of my ChipKit / PIC32 keyer. Both sides of the qso are displayed. The keyer switches the text color to…Continue

A few years ago I built a Sienna for K6KX (Fred), a long story that I will not go into.The past few days Fred has been testing it on our sked. Tonight I did a recording that can be downloaded from…Continue

This project began life a bit before Hjalmar posted his Arduino decoder project. I had barely begun to migrate my keyer software to the ChipKit PIC32 boards (Max32 and Uno32) at that time. I…Continue

Jan 2011 keyboard project update:
I am now using a much lower cost microprocessor board ($15) and have done a printed circuit board to simplify construction. Current details at: https://sites.google.com/site/w5uxhavrkeyboard/really-bare-bones-version
Two new photos show the low cost enclosure and the internal assembly.
Original notes from some months ago:
The photo below (the one with the black panel) shows my current keyboard project. It uses a low cost microprocessor board with the Atmel ATmega1280 chip. Software is written in C. The AVR Studio development environment is used and AVRDUDE is used to download to the chip on the board. Preliminary details are available at this link:
This new project is the big brother of the old PIC keyer/keyboard I have used for the past 10 years or more. The PIC project was written in assembly. The new project does not yet include the paddle keyer function, but I hope to get that done eventually. The keyboard function is in daily use now and seems to be working properly.
