There is no "may be subject to local regulations and laws" (quoting from the project page); operating such a rig is flatly illegal in any civilized country. RF regulations are enforced by authorities at the national level and you can bet that if they have to go to the trouble of tracing down the RF signal from this (very easy to do), they will be bringing the legal equivalent of a can of whoopass with them. And they will not be mollified by claims of personal use.

Again, the project you forked from literally tells users never to attach an antenna; they have enough RF knowledge to know a tiny bit of signal can go a very very long way. You clearly do not.
