I know this may sound crazy, but, would anyone out there happen to know if I can get a spectragraph display (like that on an XLT and DFX at the bottom of the screen) to work on my MXT? And PLEASE, don't just tell me to buy a DFX either,,,,,,I've owned one for several months. I'm quite willing to do some pretty severe mods. to get this done. Any help would be appreciated. Thanks. Phil.
