Don, G4LOO began by asking: What is an SNA? The answer, basically, a Spectrum Analyser plus a Tracking Generator. The SNA differs from a Vector Network Analyser because it only resolves the amplitude of a signal, while the VNA can resolve the phase angle, as well.   Don’s winning entry in the Kit section of the Construction Contest started with a design by DuWayne, KV4QB. This project is based on a number of inexpensive modular components, the brain of the device is the Arduino Nano. Don bought all the modules on the internet at relatively low prices and together they made up his kit. The finished product is impressive.

Victor’s Week-end Special project was a tuneable field strength unit with a digital display. The difference is that almost all the parts were sourced from his junk box!  The case was an old Amaretti biscuits tin which was rather small considering what Victor had planned to put inside. A tag strip holds the components while the digital display is mounted in a square hole in the lid. The problem was cutting the square hole, but it was simply knocked out using a wood chisel and hammer!

Paul, G8IUG’s entry in the Major Project class was a 20m SSB transceiver with 5w output from the CS Series of Kits by RDS.  Other modules from the same source were included, such as a voltage monitor with readout on the front panel and the CR kits Sandwich Digital VFO utilising an Arduino Pro Mini , (insert)
