Are the RIT and XIT buttons strictly for use with the FlexControl? I can't seem to find a use for them aside from the FlexContol and if there is another use for them I don't want to miss out on a feature because of my own ignorance.
RIT is "Receive incremental tuning" simply moves your RX frequency to tune in a station whose frequency is on a bit with out changing your Transmit frequency, XIT is "Transmit incremental tuning" simply moves your TX frequency a bit with out changing your Receive frequency. To use click on the RIT on the Panadapter frequency tab so the button is blue and move the slider left or right, Click the "0" to center the control, XIT works the same way for your transmit.
RIT and XIT have been around at least since the early 80's.
With today's radio's you generally wont need it but a more modern use for it is to work DX that is purposely Transmiting and Receiving on wider spaced frequencies to help with Pile-UP's. Hope this answers your question 73's Bret WX7Y
SSDR: You will find XIT and RIT controls on the Slice flag, after selecting the button (XIT or RIT)use the < and > to set the offset frequency. The button labeled 0 is a quick way of cancelling the offset.
Also the RX pane of the SSDR control panel has the controls for those functions. Gayle K0FLY
