cut and pasted from another post...
/usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua
that has the frequencies that are available via the user interface
conf:tab("advanced", translate("Advanced Settings"))
pb = conf:taboption("advanced", ListValue, "freq", translate("Frequency"))
pb.default = "18:218.75:1106"
pb:value("16:250:0982", translate("250M"))
pb:value("17:243.75:1306", translate("243.75M"))
