Title: UNID 6918 / 6930.5 kHz 1111 UTC 11OC2015
Post by: Kilokat7 on October 11, 2015, 1204 UTC

I first noticed this last Sunday morning when listening to the breakfast with Boombox show.  Two weak synchronized signals on 6918 and 6930.5 (nominal) producing dashes on the waterfall.  I can't rule out the possibility of some kind of very weak RFI, but I've never seen this before.  I checked several remotes and couldn't reproduce what I see here, but then again none that I checked had the 6940 dasher either.  This seems worthy of posting in the event that someone is testing.  You can also see the 6940 dasher clearly in this screenshot for comparison, which is a bit stronger:

I checked my SDR recordings, and no sign of this here.

I will note that the 6940 beacon was extremely weak here.
