I was reading this article: https://hackaday.com/2017/11/26/a-tempest-in-a-dongle/
The article is about using an RTL-SDR dongle to capture radio signal from a monitor or it's wire and see what is appearing on the monitor. This actually works and shows black and white image of what is appear on the monitor.
The author wonders what would someone with deep pocket will be able to do. I want to know what kind of equipment can someone with deep pockets buy, will it custom built or prebuilt. I'm unable to find the names of such parts, what part would it be? Can someone tell me? All I can find are software defined radio of capabilities shown in the article, I'm unable to find any SDRs more powerful than them.
