August 21, 2017: Individual Recordings of MW During Totality<\/h2>\n

by TomL<\/strong><\/p>\n

I setup flimsy \u201cBackpack Shack\u201d loop antenna and preselector to my Sony ICF-2010 to listen to any propagation of MW signals as each transmitter experienced Totality. My location was a picnic area facing southwest with only a small hill to the east at Ferne Clyffe State Park near Goreville, IL.<\/p>\n

\"\"<\/a><\/p>\n

I did not bring a DSP radio and computer which would have been better in hindsight. My observations were generally as follows:<\/p>\n

Anything west of my location, except for local St. Louis stations were not identifiable.
\nNoise levels were somewhat elevated because of thunderstorms that had just moved through the area during the evening.<\/p>\n

Anything east of my location experienced dramatic increases in signal along the path of totality.
\nSince large signal increases were seen with the Umbra moving AWAY from me, it would be more beneficial to use a DSP receiver with good outdoor antenna than a single frequency radio and preselector like my setup. The loop antenna sitting on a picnic table acted great and was usable to get strongest signal for each station.<\/p>\n

It is still unknown why I could not identify any stations west of me with the Umbra moving TOWARDS my location and needs further study. I thought I heard KTWO in Casper WY, but upon listening to the recording, it was a male announcer buried in the noise and unintelligible.
\nA transmitter being IN the path of Totality has a better chance of lasting longer with a strong signal than one that is just outside of Totality. Compare behavior of WSB vs. WBT.<\/p>\n

If this happens again, make sure to make multiple hotel reservations and cancel the ones not needed. Traffic was horrible and had to stay in a hotel half way from home and I aggravated an achillies heel problem in the stop and go traffic (YUK).<\/p>\n

So, it was quite disappointing to not hear anything special west of my location. As Totality neared my site, I just left the radio tuned to KNOX for the people around me to hear. Its signal did become about 25% stronger and near the end of the recording you can hear other weaker stations trying to break in.<\/p>\nhttps:\/\/archive.org\/download\/170821KMOX\/170821-KMOX.mp3<\/a><\/audio>\n

As soon as totality was over, and my picture taking was done, I returned to the radio and found 1510 khz WLAC Nashville, TN was moderately strong! And this was seconds after their Totality had already ended. A baseline reading beforehand showed this station coming in very very faintly. Subjective SINPO rating beforehand=15452, just after Totality=34433.<\/p>\nhttps:\/\/archive.org\/download\/170821KMOX\/170821-WLAC.mp3<\/a><\/audio>\n

The next surprise was tuning to 750 WSB Atlanta GA was BOOMING in! They were very clever and had no announcers. Instead they were playing snippets of songs about sun, moon, dark themes. Very entertaining! Baseline beforehand was just moderate noise, no signals. During recording, SINPO=55444 with propagation getting slightly worse near the end of the recording.<\/p>\nhttps:\/\/archive.org\/download\/170821KMOX\/170821-WSB.mp3<\/a><\/audio>\n

Final surprise was 1110 WBT Charlotte, NC, which was not in the path of Totality but just north of it also booming in but not as strongly. Also, near the end of the recording, the signal dropped off very sharply, unlike the WSB signal which stayed strong throughout the 5+ minute recording. Baseline beforehand was low noise and no signals. During recording, SINPO=43434 at 14:40 ET, then approximately 1\u00bd minutes after their maximum eclipse (14:43 ET), SINPO=33423, then at 14:46 ET a SINPO=22422 with another unidentified station breaking through playing a Johnny Cash song.<\/p>\nhttps:\/\/archive.org\/download\/170821KMOX\/170821-WBT.mp3<\/a><\/audio>\n

Tom, thank you for taking the time to share your recordings and listening experiences with us! Snagging a daytime MW broadcast from the Atlanta, GA and Charlotte, NC regions is most impressive. I reckon they were about 400-500 miles (as the crow flies) from your Ferne Clyffe, IL location.<\/em><\/p>\n

Sounds like you had an amazing experience, despite the stop-and-go traffic!\u00a0<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
