On 20 May 2019, the definition of the kelvin was redefined. Historically, it was defined as the triple-point of water being equal to 273.16 K. Starting May 20, the kelvin is defined by assigning an exact numerical value to the Boltzmann constant. This redefinition will ensure a long-term stability and traceability of the unit for temperature by making it independent of any material substance.

W7K celebrated the redefinition of
the SI unit kelvin which took place on May 20, 2019. This station was operated from one
of the most accurate temperature standards laboratories in the world in American Fork,
Utah. Times of operation were 00:00Z to 23:59Z.
The station operated on both HF
and VHF.
For HF, operation was on the 20, 40 and 80 meter bands. Echolink contacts were also possible. Thanks to K7PB for letting us use node *K7PB* (946910)
