Just signed on, I believe this is MRI, no ID heard yet. About S2 here.
Possible ID at 2020z.
Now at 2025z, the signal has faded quite a bit, I have no audio, just a carrier, and even that is almost gone.
Some audio again at 2030z, OM and YL, so pretty sure this is MRI.
Much improved by 2120z, S6 now.
