All,
Doppler measurements suggest that UKube 1 is either object 40074, 2014-037F, or object 40075, 2014-037G. The separation between these objects is now only 1 s, so no more than 7.5 km.
It is not easy to carry out meaningful doppler measurements because of the limited transmissions from the beacon in varying modes and both long-term and short-term frequency drift and other instabilities on the beacon transmitter.
