WWVH: Circa 1971

/

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

Radio Delta: July 8, 2023

Radio Delta broadcasting in English and Dutch on the shortwave frequency of 6060 kHz. Recording made in Europe July 8, 2023 at 1836 UTC using portable SONY ICF SW07 receiver operating on bateries. Receiver has been utilised outdoors to evade noise from building interference. As antenna only 1 meter telescopic internal antenna was used. Please note that in the recordings two short parts have been removed because of strong noise which covered these parts of station's signal (the noise has been generated by a bulb from a street lamp).

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

KC2XIO was an experimental radio station operated by the National Bureau of Standards in Boulder, Colorado between July 1970 and May 1971. This was to gather information in preparation of the format change for WWV and WWVH which happened in July 1971. Here are two recordings of their voice announcement (one male and one female) as heard in Ancaster, Ontario, Canada on a Hallicrafters S-52 receiver that was hooked up to an outdoor longwire antenna. The frequency used for these test transmissions was 13560 kHz shortwave.
