Looks like an AM station to me, the only thing I have close to it is 7.881.5 kHz US ARMY MARS - USB, not the Mars.

Is that signal on 7883 the only one you can receive? I see three other spurs there, one appears to be WWV but you have scanned from 2MHz to 9MHz and not received anything else?

Shortwave station? The "bubble" peak markers make it look like separate signals but I'd say high power AM SW station.

Zoom in a LOT more on whatever signal you mean. This image is too zoomed out to make out enough detail to even venture a guess. The one at 7883 kind of looks like an AM BC station, but not enough sidelobe texture, and further, on this scale it looks like it could be well over 100 kHz wide, far too wide to be a BC station.

Typically you want to see the signal in question taking up at least 10% of the displayed width, and preferably 20+%, when trying to ID an unknown.

T!

....and if it's got any sensible audio, try to decipher what (or language) it's saying.

I see at the top right it says "8.20pm" - if it's dark outside, you should be swamped with signals. An 84dB noise level is horrendous - where and what is your antenna?

Is your audio turned on? AM mode reception selected with proper bandwidth? This will help.
