[Scan-DC] Russian Numbers station broadcasting spike

[Blair Thompson]

I'm clearing out old posts. Maybe I asked about this already and forgot.

What's the point of AM suppressed lower sideband? You still have to waste power on sending the carrier? The bandwidth is narrower, but why not just send USB? Are listeners not able to provide synchronous detection?

Maybe there is no explanation. Thanks.

Sidebar: When I try to hear Alex Jones at about midnight on 4840kHz, the band is covered with noise. The radio in question is a mid-60s Sony multiband TFM-1000W in serious need of alignment, so maybe it's just me.

Just saw some reports that a "numbers" station in Russia has been very active.  UVB-76

UVB-76 is the callsign of a shortwave radio station that usually broadcasts on the frequency 4625 kHz (AM suppressed lower sideband).
