Shed Workshop: An introduction to a low cost SDR Spectrum Analyser

SDR Spectrum Analyzer

Our Ted Talk for the year (from Ted ZL2TB) was scheduled for Sunday 2 August from 1pm to 3pm at Ted’s QTH, 14 Quigley St, Newlands. Thirteen members enjoyed Ted’s introduction to his low cost SDR Spectrum Analyser (available for around $500) that can be procured through the internet. This device can be used for all sorts of purposes, with slightly differing models having slightly different features.

Ted gave a practical demonstration of potential use cases that reflected his personal interests in the VHF, UHF and microwave spectrum, such as looking at the output of the FM radio stations on Mt Kaukau in Wellington, the transponder outputs (including half transponders) from satellite signals able to be received in Wellington. Given the affordability of the device and potential to examine a broad spectrum all at once, this session was of interest to members.
