S7 signal with pretty good audio heard via the SDR in Fair Hill, Maryland, with noticeable static and noise ...
1851 UTC: Operators talking and phone noises.
1853 UTC: Operator: "Please deposit ..."
1855 UTC: Montage of more operators talking with callers.
1901 UTC: Continuation of phone noises and operators talking.
1904 UTC: "This is a recorded announcement ... Your call did not go through."
1907 UTC: "What number are you calling, please?"
1911 UTC: "The telephone company wishes you happiness all through the year!" Reception has improved, as this signal's a little stronger now and better against the background noise levels.
1915 UTC: WWV audio mixed in among all the phone-related sounds and operators talking.
1925 UTC: Male-voiced ID: "You are listening to The Bell System," then more phone sounds and operators.
1929 UTC: Off.
Thanks for the broadcast. For somebody who grew up in the 1970s and '80s, all these phone noises and operator conversations are very nostalgic!
