I have a pair of 921UAGS-5SHPacD (AR8888) that I wish to use in the amateur radio segment 5850-5925. Product literature advises a supported range of 4920-6100 MHz.

I have tried setting a channel of 5900, but it says that is unsupported. And the drop-down list doesn't have channels about 5825.

Anyone know what channels are supported above 5825 MHz and how I might set them properly?

Frequency mode set: Superchannel
channel list set according to what you want.
