The frequencies on the FAR and NEAR must be different, but from one aero, so when you set FAR, NEAR must automatically adjust how it must be. There is an option that FAR updates NEAR, but it doesn't work nice. For example on Krasnodar Center outer is 625, inner is 303. Bot when I set FAR to 625 (and I hear the correct morse code), NEAR is about 307-308 and of course I hear morse code from another beacon
