The last Tech night on Monday 21st which focused upon low cost VNA’s was a great success with John VK4JBE and Henry VK4BUD both making presentations about the readily available low cost VNAs and their practical use.
Members learned that VSWR is not the whole story, and when dealing with filters and ‘two port’ networks, the trusty antenna analyser is not always up to the complete analysis job. Hopefully we can continue the hands-on sessions with some practical workshop experiments in the near future using the club’s own VNA.
The meeting continued on until just after 10PM, so the recent discussions about the possibility of starting the meetings a bit earlier proved to be a timely topic!
