Great! Even though I use the SDRplay and FUNcube Dongle Pro+ when I work satellites, I have an assortment of the RTL-SDR types of dongles at home - and one at my office. They are a great way to get started with SDR, although with some drawbacks as KG7NXH mentioned. There's no front-end filtering in them, so having a transmitted signal nearby will swamp the cheap dongles. But for a receive-only need above 24-25 MHz, they can do the job. The RTL-SDR dongle at my office serves its purposes well - broadcast FM receiver, sometimes listening in on ham repeaters, and more. The dongle at my office is normally plugged into a PC running Linux, and I use GQRX as the software. I could take it and plug it into a Windows laptop or tablet, if I wanted to play with it on a Windows-based system, when at the office. Good luck!
