Russia’s New Mystery Shortwave Station
- nubinetwork 4y agoI was watching UVB leading up to the war, it was pretty mundane, up to where people in the Estonia / Latvia / Lithuania / Belarus corridor started jamming the channel with music or drawing pictures on the SDR heatmaps. Eg: https://www.youtube.com/watch?v=QWFg3i2dNK4 https://www.youtube.com/watch?v=QWFg3i2dNK4 After that it devolved into a popularity contest over who had the strongest transmitter or was geographically closest to SDR recievers. Then kiwisdr got ticked off and stopped letting people do time domain reflectometry to triangulate the signals. My bets are on this new signal being a troll.
- great_psy 4y agoCan you explain a bit how somebody can stop others from trying to triangulate?
- nubinetwork 4y agoKiwisdr maintains the software that is used on the web frontends of their SDRs, they just disabled the feature and (at the time) people couldn't use it anymore. There are other ways to triangulate signals, but that means buying receivers and putting feet on the ground.
- jjtheblunt 4y agowhat does triangulate mean here? i'm guessing locate.
- ggm 4y agoYes. From two or more sites plot the intersection of strongest signal radiating pattern, and the centroid is the most likely location of the transmission assuming it's single sourced, and you can plot directionality of the RF. This is called triangulation because at sea you are recommended to get at least 3 points of reference which becomes a "cocked hat" (by visual analogy) to the location being plotted, distances and angles being computed by.. triangulation. The seaborne method is directly analogous to radio signal finding.
- jjtheblunt 4y agoThank you
- computerfriend 4y agoWhy would kiwisdr care?
- nubinetwork 4y agoIt uses their server.
- nullc 4y agoyou mean TDoA not TDR.
- nubinetwork 4y agoYes my mistake, I don't use it very often... I usually only listen. Nice feature though.
- 64operator 4y agoThey didn't jam anything but the WebSDR receiver.

- east_689 4y agoThe station is also famous in HAM in China
- mike_d 4y agoMust be a slow news day at Hackaday. This is doomsday speculation about something interesting, based on someone else's YouTube video about a signal marker. The Russian Military transmits a constant signal to prevent anyone else from taking up residence on that frequency and it also allows receivers to ensure they are on the right frequency while waiting for a message broadcast at a specific time.
- boomboomsubban 4y agoThe start of a new station is itself somewhat interesting, and the only "doomsday speculation" is them saying some people think it's a doomsday machine but that isn't very likely.
- _8j50 4y agoIn the cold war they use to spin up these stations just to keep the other side busy trying to decipher it.
- randomcarbloke 4y agoI'm commenting here so it reaches relevant eyes but does anyone remember that Russia nameserver (I think) that disappeared and then reappeared somewhere else a couple of years later...that was somehow significant to the armchair intelligence community.
