Don't get confused between U.S and U.K regs - I know what you're thinking of here.
U.K - equipment requirements for IFR flight outside CAS do not require ANY radio nav aids to be carried - just compliance with the quadrantal and minimum height rules. (ANO sched 5 and associated articles)
U.S - you're thinking of the maximum distance between navaids that you should have which differs whether you are on or off published airways. (off airways - 80 nm below 18,000ft - AIM 5-1-7 (c)(3)(c))
