3. Clicking on ‘Disable C Band’ will change the text of the button to ‘Enable C
Band’. Clicking on it again enables transmission just in the C band with center
frequency as set in the transmission control section.
4. To enable dual band transmission, set ‘IF Freq’ to 2.727 in C band and -2.727 in B
band tabs. Repeat step 3 above for both disable C and B band buttons to enable
transmission in both the bands. Setting these numbers will set the center
frequency of operation for the transmitter in dual band to be 923.5MHz. No other
IF frequency offsets are accepted by the GUI.
5. Click on ‘Set WB to Basic mode’ which will start streaming pressure and
temperature data from the weather sensor connected to the transmitter board.
Make sure the pressure and temperature values change for 0,0 to valid
measurements.
6. Click on ‘Save all’ button to set the rest of the parameters on the transmitter board.
7. Clicking on ‘Start transmission’ will change the text to ‘Starting’ and after 5-10
sec once the board starts to transmit, the entire GUI panel will get disabled except
‘Stop transmission’.
