Hi well ... cross tone is a little complicated and strongly depends on the radio as every model support it in a different fashion. BTW I'm working on a patch for FT857 driver cross tone support as I mixed up things when I wrote it.
A source of information on how tones and cross tones works in chirp is http://chirp.danplanet.com/projects/chirp/wiki/DevelopersToneModes keep in mind it has been written with developers as target audience but I think it can help.
In a few words cross tone are all tone combination that mix together ctcs and dtcs or use different tone codes for tx and rx.

Hi, I couldn't find documentation explaining how the "Cross tone" option works. I'm guessing it's to set TX CT and RX DCS, or TX CT and RX none, or other combinations, but I wasn't sure which way around it all goes.
Could you point me to the info?
Thanks, Toby
