A few years ago I migrated almost entirely to OSX & Ubuntu. However I still had to maintain a Windows copy on one of my harddrive partitions, since a few applications were just available for Windows. In particular, DG8SAQ’s superb Vector Network Analyzer (VNWA) software. I can already use most of the applications in a Virtual machine, with the benefit of not having to reboot and change the OS, but DG8SAQ’s software with it’s USB I/O always gave me hard time.

I was curious if the performance of our 4O3A high power Bandpass filters could be improved with additional coax stubs in parallel. We were operating at ED1R for some time now with the added stubs, and we are pleased with the results. Check out the details!
With his low cost, high precision Vector Network Analyzer, Tom (DG8SAQ) started a revolution in Ham Radio. Thanks to his efforts, amateur (and professional!) enthusiasts have now the possibility to perform measurements which were reserved to well funded HF laboratories before. In this video, Tom explains the evolution and capabilities of his VNWA and why even NASA relies on it now as well!
