The RADIO FACTORY dial lists stations that publish their own streams on the internet. Your browser (or the Windows app) receives the sound directly from each station's server; RK-G does not relay or store it.
Please keep your recordings for your own enjoyment, and do not upload or distribute them.
If you represent a station and would prefer not to be listed, please email media@rk-g.com and I'll remove it right away.

RK-G apps are free, original software that include the third-party components below.
The same goes for TAPE FACTORY Lite, the version embedded in partner pages.
