Starting early in the morning this time. 0700 UTC to 0820 UTC. http://msk.swl.su:8073/ remote SDR, focusing on 25-30 MHz:
Lots of Russian taxis all over 26 MHz and 27 MHz, mostly in the upper part of 27 MHz with some in the lower bands (25 MHz and 26 MHz). Noticed some FM voice activity in 10 meters as well, presumed these were taxis (and turned out to be right). Lots of legit CW and SSB phone amateur activity on 10 meters as well.
