XIT function for external radios that do not have one. To allow transmit on slightly offset frequency. Needs slider control or similar in SDRC to set the offset amount.

Is the offset recently added to the external radio control intended to provide an XIT function? If yes then thank you for adding it. However there is something strange about it. For example:

Offset set to -200hz
SDR freq set to 10489820.000 khz
External radio display reads 432320.200 khz
External radio shows 432320.200 khz

Press ptt on radio and release again
SDR reads 10489819.800
External radio display on sdrc reads 432320.000
External radio shows 432320.200

Every time the PTT is pressed and released the SDR and ext radio display drops by 200hz or changes by whatever the offset is set to.

Is this a bug or have I got another setting wrong somewhere.

You're better off using the screenshot function in Console and posting the whole screen.
Simon will then be able to see everything, and no possibly key information is missed. Dont leave anything out....

Just FWIW please don't chop up screenshots, the whole console display is of interest.
