WWV Frequency Reduction Announcement - 1976

In 1976, radio station WWV proposed curtailing operation on 2.5 MHz, 20 MHz, and 25 MHz to reduce operating costs. Operations on 20 MHz and 25 MHz were ended on February 1, 1977, but the 20 MHz transmitter was placed back on the air two years later.

The audio is from a tape recording I made of WWV's frequency change announcement in 1976. The image is from the main tuning dial of the receiver from which the recording was made.

Thankyou for the info on CHU. When did the change take effect????? In the mid 90's I used to use CHU to check calibration on my SB-102....Looks like I won't be doing that anymore. Man are things changing in the shortwave world.

@WX5G The frequency change took place on January 1, 2009. The change was necessary due to an ITU HF global reallocation that re-assigned the spectrum just above 40-meters to broadcasting. The problem was that CHU is licensed as a "fixed service", rather than a broadcast service, so it had to move. In fact, some broadcasters had already started using 7335 kHz before CHU had officially vacated the frequency! Their other frequencies remain unchanged. WWV dropped 25 MHz back in 1977.

Wow !! Have things changed. WWV and if propragation was real good you could hear WWVH in the background. They used to be on 2.5, 5 , 10, 15, and 25 MHZ. haven't been active for awhile. Did they change?????? Also CHU used to be on 40 meters at 7.335, has this changed also??????

@WX5G CHU QSYed to 7850 kHz a few years ago.

WOW! How do you still have this? 73's de w1rmd (ex. w4cgr)

@ryan29073 I recorded it back in 1976 when I was 12 years old thinking it would be a neat thing to look back on in the future. Guess I was right. :-)

That's an old Hallicrafters receiver main tuning dial. It was used on several models. I still own the HQ129 and HQ160 and know 'em well.

Thank you for recording this in 1976, holding on to it through the years, and now posting it on youtube.
