Eclipse Report

Eclipse from downtown Wolcott, CT, at 1854 UTC
(photographed while holding my telescope's sun filter in front of the lens of my iPhone 6)
I made over a dozen recordings of the AM broadcast band during the eclipse and I will review them later. I also had my C.Crane CC Skywave receiver outdoors with me during the event. I programmed six frequencies from this list into the Skywave – 650, 670, 750, 1040, 1190 and 1510 – frequencies that are dead air during daylight here.

I heard nothing on these frequencies during the hour leading up to the eclipse maximum here in Wolcott at 1845 UTC. About 15 minutes later, I could hear a weak signal on 1510 that became stronger during the next ten minutes – strong enough to be intelligible and identifiable: WRNJ in Hackettstown, NJ, transmitting 2,000 watts, 113 miles to the west-southwest. The signal peaked at about 1915 UTC and then slowly faded into the noise disappearing completely at about 1930 UTC.

I hear WRNJ most nights, but never during daylight, so I assume the eclipse's "nighttime" conditions were the reason I heard it this afternoon.


  1. Heard 750 WSB Atlanta, Georgia with their 50kW signal on the opposite side of the path of totality in the eastern time zone
    that follows down the Piedmont Plateau.

    Time local(EDT): 2:34 p.m.; 2:37 p.m.
    Time (UTC): 18:34; 18:37
    Signal strength:
    (1) Fairly-weak @ 2:34 p.m./18:34 UTC
    (2) Very-weak @ 2:37 p.m./18:37 UTC
    Distance: 685 air miles
    Azimuth: 230 degrees
    Location: Easton, Pennsylvania
    Zip code: 18042

    Note: During the two times listed above, WSB signal only lasted seconds worth within the minute
