Chris.SE: I was surprised to see C35. I assumed there was an error on the list of sandy heath channel frequencies.
I am interested in C35 because it is transmitting services not on the other sandy channels, such as Sony movies classic.
By the way in my last post, auto spell corrector managed to turn "retune" into "refund". Maybe this is appreciate, comment refering to the TV license and the inability to access all the Freeview channel services..

Chris.SE: can we assume that scheduled moves of sandy heath channel allocations will be postponed if they conincide with unusual tropospheric radio propagation. Or are we to see messages to return at a time when the new frequency allocation will be blocked by interference.
One must wonder why the mobile phone companies are so keen to gain access to the higher Freeview TV frequencies, when they are subject to tropospheric RF ducting and scattering. Something that is going to become even more common due to the effects of global warming. Are the mobile phone operators not concerned about the disruption to their services when they attempt to use these frequencies in the mobile network backbone.
While the 5G is not directly responsible for the current free view interference, the sell off of the high frequencies in the band, must have had an impact on channel reuse distance planning, squeezing the free view channels closer together and thus reducing the available frequency reuse allocation distance, making co-channel interference more likely.
