strange broadcast @ 6750 Khz 1457z 2/26/16
« on: February 26, 2016, 1515 UTC »
some sort of over modulated 5Khz bandwidth AM broadcast thats on/off intermittently with deep fades (NVIS)
confirmed its not my receiver as i am also receiving this on the SDR console W1NT remote receiver.
currently receiving this in the northeast coast of the USA.
could it possibly be a harmonic from an AM broadcast radio station thats having an antenna problem ?

Sounds like a QSO, one side is clear, the other sounds distorted.  Now some digital mode. Military or MARS?

i think you might receive this transmission Chris if you park long enough on it since its very intermittent.
if you dont receive it, try W1NT remote on SDR console (its received there also)
to me, it sounds likes a harmonic being generated from a faulty connection at the antenna tower site because its very intermittent and when it happens, its seems to be cyclic like its a hard line cable moving around in the wind.
pretty strange if you ask me.

trying to ID and locate the actual source of this harmonic transmission, searching through the AM broadcast band for something that sounds like what im hearing (some talk show about the emmys and oscars) has proven fruitless.
i'll keep listening to this and maybe i might hear a station ID.
