Not a full SDR, but there are so many cheap hacky solutions that are quite enough for basic experimentation.
If transmit only, extremely low power output (enough for a few meters of range), terrible harmonics, On Off Keying (OOK) and potentially Binary Frequency Shift Keying (BFSK) are ok, a square wave generator is enough. Options include a Raspberry Pi (https://github.com/s7mx1/pihat) or a Si5351 breakout board ($10). If you abuse harmonics to get to the target frequency, even a USB serial adapter can be enough (https://hackaday.com/2018/12/06/your-usb-serial-adapter-just...).
Disclaimers: These options are educational, but certainly not very professional. They're also a fair bit off the well trodden HackRF/Gnuradio path. Lastly, please do get a ham radio license and play legally.
What a cool device. Small word of advice to whoever maintains the FlipperZero website ("webmaster" in the old days): clicking on the logo on any of the Blog pages leads to the blog index, which is not terribly helpful for someone who ā like me ā landed on a blog article page and then was wondering what this was all about. It would make more sense if the logo, like the "Home" link in the navigation, consistently lead to https://flipperzero.one instead of https://blog.flipperzero.one. Same thing goes for https://shop.flipperzero.one fwiw.
Sounds like you want one of the 3rd party firmwares.
