WWVB would continue being in Boulder being an experimental station for numerous a lot more a long time, though NBS personnel labored on the look of a whole new VLF station at twenty kHz, and to the acquisition of the permanent site for all of its radio stations.
Representatives of some actions at Redstone expressed concern about probable radio frequency interference through the proposed high ability LF station, and after substantial conversations it was determined that the new LF station should not be crafted at Redstone. By regulation, the ARRA money had to be put in in a confined time period, which did not offer the chance to make ideas for another area. The ARRA funding was reprogrammed with settlement by Congress plus the Administration that more info can help fund the construction of a completely new Highly developed investigation and measurement laboratory over the NIST Boulder campus [84].
