RECEIVER SETTINGS

The receiver settings can manipulated via the GUI. To access these options, navigate

to Settings->Board Options to see a similar screen as below:

BOARD SETTINGS DIALOG

The drop-down options for the center frequency contain common settings for the

receiver. The Hex input box provides a convenient way to visual the decimal frequency

in a hexadecimal format. The modulation can also be configured between OOK and

FSK. When satisfied, press the Program Receiver button to apply the changes to the

board. The kits come with a receiver that has a matching circuit that is designed to a

specific frequency. Changing the frequency far from its originally designed center

frequency will have adverse affects on the receiving range.
