UNID 6880 AM 1505 UTC 21 SEP 2017
« on: September 21, 2017, 1506 UTC »
Seeing a large signal on the waterfall at 1505 UTC.  The nice loud and wide AM signal usually found on 6925 kHz AM during daytime.  Operator must be trying alternate frequencies (as 6880 kHz has been seen many times before it makes sense).  

1506 UTC - Steeler's Wheel - Stuck In The Middle With You
1507 UTC - deep fade, then back up to SIO 444 with S7-S8 signal strength and very little noise
1514 UTC - minor data QRM on 6880 kHz USB upper side of the AM signal, however this station is so powerful it doesn't matter
1518 UTC - checked Rochester, NY SDR, have signal at S7 with very little noise
1527 UTC - The Beatles - A Day In The Life
1528 UTC - barely readable (really carrier on 6880.0 kHz only) signal on Ohio SDR
1533 UTC - George Harrison - Give Me Love (Give Me Peace on Earth)
1555 UTC - Procol Harum - Whiter Shade of Pale
1621 UTC - The Beatles - Come Together
1624 UTC - The Rolling Stones - Bitch
1629 UTC - signal down a lot, now S3-S4, much harder copy
1630 UTC - music back up some, signal now S5
1635 UTC - still having trouble copying the music due to more noise

Came back to radio/computer at 2130 UTC.  Still seeing a carrier on 6880.0 kHz on several East Coast USA remote SDR receivers.  No audio heard at this time...

Edit:  checked one of the VA SDRs and can hear music at 2131 UTC.  Strong S9 signal with the usual nice wide and strong AM audio with powerful signal and modulation, 10-11 kHz bandwidth.  Noise level has increased a bit but still sounding good (only in VA though).  Earlier today, this station was loud all up and down the East Coast.

I heard something there about 23:15 in AM. S-2/S-3 signal but the audio was low, I couldn't tell what it was. When I tuned through there a little later it was gone.
