Used to check my new Baofengs
With this device, I know that my newer Baofengs have clean signals. My 10 year old Baofengs do not. This was a great tool (with an attenuator) to find out. Way back when I got my ham license, a Spectrum analyzer like this would set you back $5-10K. To get wone for under $150 today is amazing!

Excellent Value in a Compact Spectrum Analyzer
The TinySA Ultra+ is an impressive compact spectrum analyzer for its price point. I tested it with a professional signal generator and was genuinely impressed by its performance and accuracy. The PC-controlled software is also a standout feature—making setup, measurements, and configuration both easier and more comprehensive. Highly recommended for both hobbyists and professionals alike.
