In the current Russia-Ukraine conflict we've seen several noteworthy radio related events occurring over the last few days, mostly throughout Twitter. These recordings are cross-referenced with reports and videos of actual tank sightings and destruction in the areas discussed on the radio.Ī later recording highlights communications from a distressed Russian vehicle under attack, requests for air support being unfulfilled, and urgent requests for supplies like fuel, food and water. The story focuses mostly on the audio recordings that highlight communications between Russian forces discussing attack plans, including plans to bombard residential areas with artillery. In the video screenshots of recordings played back in SDR# and various WebSDRs are displayed. UKRAIN RADIO INTERNATIONAL SOFTWAREIt appears that much of the invading Russian forces use simple unencrypted analogue voice over HF channels that can be intercepted and recorded by anyone with an HF software defined radio, or anyone willing to monitor nearby web-based SDRs like KiwiSDRs and WebSDRs. Some of the communications reveal the extent of the logistical issues experienced by the invading forces, and perhaps have even recorded evidence for war crimes. The New York Times have recently run an incredible video story about how Russian radio communications are being intercepted and recorded by ham radio operators and open source radio monitoring hobbyists in Ukraine. If you are interested, previously we posted about a similar video story from the New York Times, and have covered various bits of radio related news from the war in two previous posts. And how volunteers are helping translate, confirm authenticity, and collect information about possible war crimes. The FT story focuses on how open source contributors from all over the world are helping to monitor internet connected WebSDRs that are close enough to receive Russian radio communications. But early on in the invasion it came to be clear that much of the Russian forces are much less advanced than first thought, and are using cheap civilian unencrypted radios that anyone nearby can listen to with an RTL-SDR or via a web connected SDR. UKRAIN RADIO INTERNATIONAL FULLIn these modern times, we would expect the Russian military to be making full use of encrypted radio communications on the battlefield. The Financial Times has recently run a video story on how hobbyist WebSDR setups are being use to record Russian radio communications during the war on Ukraine.
