15 Feb 2024 – Talks by Construction contest winners

Graham presenting

Graham, G4JBD began by explaining his Major Project winner. As his HF rig wasn’t the easiest for scanning quickly between different frequencies, modes, bandwidths and power settings he designed the project to do just that. His unit is based on the Arduino interfaced through the CIV port on the rear of the HF rig. In all there are one hundred different frequencies with the necessary parameters stored in the memory. All the  design, building and coding were done by Graham. He did admit it took longer to debug than to build!

Since Victor, G3JNB was still a bit ‘under the weather’ Graham took on the task of explaining his Kit Project, the Rooster 2W 40M CW transceiver, supplied by Kanga Projects. The rig is direct conversion with crystal filters. RIT is provided to shift the crystal frequency a short way off the calling frequency, if required.. Upon finishing the project, Victor decided to check it out by using the Reverse Beacon Network and was pleased to see he had been received in over fifty different station from North and Sough America as well as Europe and the middle East!  Very impressive for a kit just slightly larger than a playing card.

Speaking as the winner of the Weekend project, Paul, G8IUG produced a range of projects built in the past. His winning project this year was an RF Linear Amplifier build from a kit.
