 ## Frequency Selection 
-The hardware configuration byte of the K.I.S.S. protocol is used to select from a predefined table of frequencies. 
-The K.I.S.S. protocol limits the configuraiton byte to...well...only a byte so a table is required. Currently, only 16 frequencies are defined to allow the 4 remaining bytes to be used for future capablities.
