Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

Time signal station WWVH in Kekaha, Kauai, Hawaii was occasionally heard over WWV in Fort Collins, Colorado from my receiving post in Ancaster, Ontario, Canada in the 1970's, particularly on 10 MHz or 15 MHz. Here is a recording of their voice announcement from 1971, when they were still using the term Greenwich Mean Time as opposed to Coordinated Universal Time. The familiar "Aloha" is heard at the conclusion of the announcement.

Reception location: Ancaster, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 using a longwire antenna
