What they have managed to fit inside this package, is almost impossible for me to wrap my mind around. Other than not being built to take abuse, this is by far the best bang for the buck, I've ever seen on any piece of test equipment. So far, it's been working great with no noticeable changes from those connectors. I've been using the flexible cables with the adaptor that it came with. Handle it with care and when you drop it or break a connector off with rigid cable, remember it only cost $60 for a reason. Everything from the power switch, to the connectors does not give the appearance of being able to handle any abuse. It is also built to match the crazy low price in terms of ruggedness. Would you believe that was the result of a cheap RF sniffer circuit, rectifying RF without being bypassed? This tiny SA is very 'tiny'. One amplifier managed to add tons of harmonics, just being inline and off. The old tube FT-101ZD had less harmonic content than a solid state Kenwood.

I've checked a wide range of amplifiers and HF rigs for harmonic content, some with surprising results. The SA has allowed me to do many things, very easy. Walking by the police station looking at the 800 band, got me all of their active simplex frequencies they use when they don't want everyone listening to the repeater, to know what's going on. I was very surprised to learn it also does 90% of the functions my expensive and very heavy HP signal generator does.

The Tiny SA arrived yesterday and I've been experimenting with it ever since.
