GB3RAL at 50.05MHz should be a good signal in Warfield. I do not know how accurate it is, it is well beyond my ability to measure it here at home. The reference it is driven from is locked to GPS with a long time constant and should be close to one part in 10^10. However, the frequency is DDS derived and there may be a very small fixed offset error of a mHz or so due to the limitations of a 48 bit frequency control register. For most purposes it will do. There is also a companion beacon on 70.05 MHz you could use.

Don't forget you have 50MHz now, and from your Callbook QTH in > IO91, you may be able to receive the GB3RAL beacon on 50.050MHz.
