Can't figure out how to post a picture/screen shot, something's changed on how it's done.

This post was under the QSL heading because I think that was the majority of images shared, but the directions apply to any image. Scroll down to my photo comment to see an easy way of sharing images if you do choose to use imgur.

it is "HF Trading", see discussion:
https://www.hfunderground.com/board/index.php/topic,44885.0.html
when its on, it totally kills my chance to operate at 6880Khz.
it seems to come on at random times and when it does come on, its on for awhile.

2120 UTC - Just finished reading your post and I noticed it on then off.
2122 UTC - Back on and going strong at S9+20db in WNY.
2127 UTC - Signal is gone.

In addition to knocking out 6880 kHz the high frequency trader high frequency data signal (HFTHFDS) knocks out the freebanders usually heard on 6900 kHz and other common peskie frequencies like 6919 kHz.  I noticed an uptick in activity on 6800 kHz and nearby frequencies as well as 6950 kHz USB (!!) so they might have just moved to below 6850 kHz or so and above 6940 kHz or 6950 kHz.  Seems like 6940-6950 kHz is another area to avoid with the Link-11 signal that is often found on 6941 kHz/6942 kHz.  Probably not a good idea to QRM the US Navy, even if you do have a legit FCC Part 5 experimental license.

Not to mention MARS ops and the FEMA SHARES network that operates on 6910 kHz.

this "HF trading" thing seems to be jumping all around the band, the Amateur band, Utility band and even the Broadcast band.
i think i will go back to 5150Khz this spring, its been quiet this entire year..
this requires major antenna work to accomplish and the weather right now isnt favorable. :-\

Big signal centered on 6890 kHz or so is back at 2247 UTC.

0053z 1/13/2019  Looks like it moved to 6840 in the last hour or so. It was encroaching upon the 6925 freq, but even Old Time Radio's frequency is in the clear at 6870 kHz.  The QRM now looks like just noise, no modulation, vs the previous screenshot I took at 2319z.

Briefly off @ 1:01:00, back on air at 1:01:30 for 30 seconds, now off again...

While checking the 8000 and 9000 kHz freqs this AM at 11:51z Jan 15, 2019,  I found this:

Similar to the above images taken near 6900 kHz.
