I just had mine, a 403-470 split, programmed for a couple of frequencies at around 471MHz, and although it gives you error messages, it takes them and seems to receive okay.
While we're talking about the XTS3000, is it possible to have the display light come on when a signal is received? Mine is programmed so that the top (purple) button turns on the backlight, and I know the time it remains on is programmable.
