If you provided DE as your country code (Germany), you'll notice that all channels in the 5GHz band require DFS, so you won't be able to use the radio1 device. A workaround is to choose FR, instead. This enables channels 36, 40, 44 and 48 at least. However, it might be illegal to use a foreign country code.
