Bill Somerville 9f1cd9defd Fix issue with v1.8.0 trashing v1.7 working frequencies
Note  that  reverting  to  v1.7  will  invalidate  any  saved  working
frequencies  from v1.8  but proceeding  to v1.8  again will  present a
reset set of working frequencies i.e. any user defined entries in v1.8
will be lost of a v1.8 -> v1.7 -> v1.8 transition is made.
