tinySA: Finding Interference and Aiming Antennas

Long time readers know I like to test compact and, where possible, low-cost equipment. Recently I found another tool to add to my backpack when I get back on the road. 

Seven years ago, wanting a spectrum analyzer I could throw in my laptop bag, I spent around $500 (I don’t remember the exact price) for a 5 GHz spectrum analyzer a bit bigger than a USB flash drive from Triarchy. The company is still around selling miniature USB spectrum analyzers that can cover frequencies up to 8.15 GHz. I’m sure the analyzer and associated software have improved since I bought my unit.
