There is an uRADMonitor unit in Odense, Denmark that went silent for some time because of a failure in the high voltage internal inverter. This unit, part of an early set of first prototypes, was using a ferrite choke that eventually reached saturation with the increasing temperatures of the summer. As a result, the high voltage inverter failed to produce the voltage required for the Geiger tube, and the device ceased to function.
The unit has been upgraded to one of the new ferrite chokes used in the later models and now, the unit is functional again, delivering data 24/7 from Odense, Denmark:
