I ran across this fascinating historical article about how the Associated Press and the New York Daily News each smuggled a covert shortwave radio transmitter into the 1935 courtroom trial of Bruno Richard Hauptmann, who was charged with kidnapping and murdering the young son of Charles Lindbergh.
Neither news organization knew of the other’s covert transmitter, and crossed signals led to erroneous news of the verdict being reported.
Wow! What a fascinating bit of history, Ed! I bet those briefcase transmitters were heavy!
I don’t think you can do that today, It will not get past the baggage check in the courthouse.
