Until today I was able to receive test carriers in subbands 11200-11450 and 11450-11700 MHz only, which are in widebeam for sure (strong carriers for my location). But I had nothing on the spectrum on all other subbands, so can't confirm another posts.
This morning I see carriers in 10700-10950 MHz subband:
~10860H,
~10890H,
10906V,
10845V
Weak power, but the fact is interesting, also the last carrier 11954H I can see on the spectrum too. Seems they had adjusted downlink dish to the East, else another beam testing now.
