Technical Support / What should I see/hear tuned to 869.525Mhz with a Software Defined Radio?

The background to this query: I'm updating the Rosetta in a shared aircraft. For a while it has not been showing up on Vector plots, although the SkyEcho we also carry has. After a lot of mucking about, I finally looked at the set hex ID; someone had set it to a random number, so It wouldn't be recorded against this aircraft. I did look at Vector for that number, but nothing recorded. So, even if the hex ID was wrong, it still looks like no P3i is being transmitted. (but then I'm not sure how long ago the PA was used.
As I had a leftover DVB-T USB Receiver Dongle from upgrading from the Classic to Rosetta, I set it up as a SDR and listened on 869.525Mhz while the PA Rosetta was operating near by. I appeared to get nothing, though there is certainly a lot of transmissions on nearby frequencies. Nothing changes PA on or off.
Is that a legit test of the P3i broadcast?
