Update radio-programming.rst (#2560)

added a fix to a common issue that happened to Israeli teams that made radio configuration fail because of incorrect network adapter reading due to bad Unicode of the tool.  I believe that can happen to other teams that their PC's OS is not mainly English.

 - Plug directly from your computer into the wireless bridge and make sure no other devices are connected to your computer via ethernet.
 - Ensure the ethernet is plugged into the port closest to the power jack on the wireless bridge.
 - If using an Operating System configured for languages other than US English, try using an English OS, such as on the KOP provided PC or setting the Locale setting to "en_us" as described on `this page <https://www.java.com/en/download/help/locale.xml>`_.
+- Due to Unicode incompatibles, non-US Teams may face a configuration failure because of incorrect network interface reading. In that case, change the network adapter name to another name in English and retry.
 - Some users have reported success after installing `npcap 1.60 <https://npcap.com/>`__. If this doesn't resolve the issue, it's recommended to uninstall npcap and the radio tool and then reinstall the radio tool in order to get back to a known configuration.
 - If all else fails, try a different computer.
