Well it started life as a probable anti-satellite killer sat. Now it appears that Cosmos 2499 has morphed into a hamsat? First, Paul Marsh over at UHF-Satcom has discovered the S-band downlink for this satellite. Here is what Paul posted to the UHF-Satcom newsgroup:
"Confirmed S-Band downlink from Cosmos 2499, cat #39765 on 2280.000MHz. Transmitter activated with the satellite is at 5 degrees at Moscow. Quite a good signal using 1M antenna."

He may have different functions, some of them civilians, some - the military. In confirmation to the first statement I was today adopted a scientific telemetry signal with COSMOS 2499 on frequencies 435.465 MHz and 435.565 MHz. TABLETSAT-AURORA. The first time a strange signal that I could not identify, I noticed in the summer during the reception of satellite TABLETSAT-AURORA. In the picture once again screenshot summer, found in the repository at: On it you can see 2 data link with COSMOS 2499 (as I now know) and the lighthouse TABLETSAT-AURORA. A lot of time spent on the search for the source. First time I have access to the signal height of the object identified approximately 1500 km, calculate the approximate TLE based on my observations and this led me to the COSMOS 2499."
