 Currently the most common platform for Horus Binary telemetry transmission is the Vaisala RS41 radiosonde. Using [radiosonde_auto_rx](https://github.com/projecthorus/radiosonde_auto_rx) we track and recover these radiosonde and reprogram them with [open source firmware](https://github.com/mikaelnousiainen/RS41ng), which generates the Horus Binary modulation. 
 These radiosondes are launched in many places around the world, so go hunting and get your own free balloon tracker!
 
+Roel Kroes has also written firmware for a balloon payload using the RadioLib method, available here: https://github.com/RoelKroes/HorusBinary_Tracker

 **If you are going to fly your own payload using Horus Binary, you must get a payload ID allocated for your use. This can be done by [submitting an issue](https://github.com/projecthorus/horusdemodlib/issues/new/choose) or a pull request to this repository, or e-mailing me at vk5qi (at) rfhead.net - NOTE: I will no longer be assigning Horus v1 IDs. Please switch to using firmware that supports the Horus Binary v2 format, e.g. [RS41ng](https://github.com/mikaelnousiainen/RS41ng)**
 
 **Do not use the testing (4FSKTEST-V2) payload ID on an actual launch!**
