This may interest some who would like a Spectrum Analyser but not the expense of what is currently available.

It is not yet on the market but coming soon in the style and size of the NanoVna.

Obviously not in the league of the Siglent/Rigol etc offerings and only with a bandwidth up to 300MHz, but should be useful nonetheless

Keep an eye on the link below for more info.

To add in my two cents worth, I've had one of these for a while now. It's usable as high as 960Mhz. I'd recommend using a bandpass filter if near a source as the LNA doesn't always handle strong signals gracefully, but honestly for around $75 it's amazing.

Just had squint at the TinySA stuff.

It's quite astonishing about the IP theft via Chinese rip-offs.
