I did not record exactly where these were taken at Rye.
The heavy sliding concrete hatches that gave access to the buried building. It seems that the larger hatch was used for getting the bulky equipment into the building, and the smaller one for personnel use. (An emergency escape hatch was located at the opposite end of the building, seen in the foreground of the main photo)
Don't know what this is, but it seems to have some kind of channel going up to it. I am told that this was for feeder lines on the receive tower.
Another view of the hatches,
Something else sticking up out of the field, which had something bolted to it, and a cable duct. As this was close to the tower base, I presume it carried cabling to the tower.
