Topband: Amazing Video of an extremely large circular array

Since some of these large antenna sites are no longer used it could be 
an ideal location for a SRD receiver feed (for 160 meters only) and with 
sufficient delay during contests to avoid their misuse, as a means to 
study propagation.    A lease under a radio club would be an awesome 
experience to have active radio receivers in other parts of the world.  
Yes there are many SDR's all over the place but few have anything decent 
on topband as an RX antnna.  Some of the remaining locations are in 
caretaker status and the owners maybe interested in turning them over to 
radio clubs or universities for such a research project.  A Wi-fi 
connection, a router server, and a bunch of SDR radios, hooked to the 
antenna various antenna ports for switchable options, would enter a 
whole new level of experimentation on topband.
I remember when 160 meter and EME enthusiast Sam Harris (forgot his 
call) used the Arecibo Space Telescope for moon bounce.  His efforts 
began a whole new resurgence of interest in this communications mode.  
now even some DX-peditions are trying it.

Why not use them before they are gone?
