Tom Benham, now a silent key but who most recently held callsign W3DD, was a ham radio pioneer, and being blind didn’t even slow him down! Join us now as W3DD recalls more about satellites in the early days and his experience with a Senate investigation. 
The Teletype Episode
We were a very active part of NASA tracking for a couple of years and the teletype was our means of receiving messages about launchings. One night I stayed in the trailer all night because there was to be a launch about five A.M. We had fitted out the front part of the trailer with a couch, a hot-plate, coffee pot and other things for comfort. I was awakened about three in the morning by the teletypewriter coming on and typing something. Of course, I didn’t know what it had written. Perhaps the message required a reply. If so, I would have to use the phone and find out what it was. After thinking about it for a few seconds, I got up, sat down at the machine and wrote, “If what you just sent requires a reply, ring the bell three times. If no reply is required, ring the bell twice.” After a few seconds, the bell went ding ding. I went back to bed until five o’clock. A couple of days later, a man walked into my lab and said, “The office in Philadelphia sent me out here to find out what that monkey business the other night was all about.” “What monkey business?” “That business about ringing the bell three or two times.” When I explained it to him, he got a huge bang out of it saying “Gosh, wait until I get back and tell them that!” and he left. “Voices of the Satellites” got additions made to it during this period. We got the recording of Eisenhower’s Christmas message broadcast from a satellite at Christmas 1959, telemetering signals from many satellites, John Glenn’s flight in which he talked about the ice crystals, Russians talking back and forth between two space vehicles. As a matter of fact, the news people were out several times with cameras and recorders to watch and listen to the signals as we picked them up. We were not able to pick up satellite signals until they got above the horizon, so there was a delay of about two minutes after launch until the satellite was about 100 miles high before we made contact. In about 1963 we were monitoring a launch. We waited for the two minutes and then began to look for the signal. Several minutes passed with no contact so I went to the teletype machine and asked what happened. In two or three minutes the teletype machine wrote a very short message. I asked someone to read it. All it said was “splash.” One time when I thought we would be able to hear the Russian astronauts talking from one ship to another, I invited a member of the University of Pennsylvania Russian Department to come listen. He did and we got a very good signal. Unfortunately, all they talked about was trivia about temperatures in the cabins, how their food was holding out, and such like. But it was interesting to us and he seemed to get a big kick out of it. An interesting but small contribution to the Space effort was made by Ham radio back in 1959. I mentioned that President Eisenhower provided a recorded Christmas message just before December 25th that year. The story has it that the message had not arrived in time for the launch. The vehicle was closed and launch was a few minutes away. A Ham, identity not known, rushed up with a recorder and equipment and said, “Hold it! let me radio the message to the receiver in the “bird”. He set things up and sent the taped message to be stored aboard. I recorded the result when it was transmitted some time later.
The Summons
A rather amusing incident took place early in the satellite project. During the first couple of years, there was much conversation about the fact that the Russians had launched before we did. The project for launching was well under way in this country. Werner Von Braun, the German Physicist who was responsible for the development of the V1 and V2 rockets in Germany, was brought to this country at the end of the war and was making good progress organizing rocket development down in Alabama, but the red tape and time spent arguing delayed our program so that the Russians got ahead of us. There was much talk in the US Senate about why we were behind. There was an article published in one of the popular magazines telling what a good job Russia was doing. A Senate Committee was convened to investigate matters. The author of the article and I were subpoenaed to appear before the Committee. I got a small recorder and a few tapes to take with me to demonstrate what I had been recording and asked Corlies to accompany me. We were shown into the committee room and the other fellow was called first. They gave him a hard time and he did not present his information very coherently. The tenor of his remarks was that the Russians were way ahead of us, that he had been there and seen for himself.
Senator Brooks, the chairman said something like, “Well, you certainly have been given a snow job and what you have said does not seem to mean much.” Then I was called to the witness table and the chairman said in a sarcastic tone of voice, “Now, what’s your story?”
“I don’t have a story, as you put it, sir. You summoned me so I’m here. What do you want of me?”
His attitude changed immediately. He said, “We’ve heard that you have been very active in tracking satellites. We’d like to hear some of your recordings and ask a few questions. Please give us a summary of your activities.”
Things proceeded peacefully and pleasantly after that. I played a few samples of the satellite signals and explained what they meant and the information that could be derived from them, both US and Russian vehicles. They seemed to enjoy what I played and were friendly and interested.

The Trailer
During April of ’59, the students and I heard of an offer from the Government. If we went to Indian Gap, near Harrisburg, we might be able to pick up some surplus equipment. Two boys and I went and we found a fully equipped trailer that was designed for tracking aircraft. It had a parabolic six-foot dish on top that was driven by a sophisticated system from inside. The trailer was 20 feet long and about 8 feet wide. We could have it for the price of getting it hauled to Haverford, which turned out to be $200. The college comptroller authorized the expense and the trailer was parked in a little lot behind the Physics building. With the help of several students, chief among them Amateur Ridgley Bolgiano, the trailer was converted into a satellite tracking station. The 6-foot dish was too small, so we set about finding a larger one. I had heard that ITT, in Nutley NJ, might be interested in giving a hand, so three of us went to visit. We were received most cordially and I asked my contact if they had any parabolic dishes that were due to be scrapped. He paused a minute, looked out the window, picked up the phone and called the Disposal Department. “Hey Jim, you know that 12-foot dish outside my window? Well, it looks like hell, cluttering up the lawn. Please send it to Haverford College, attention T. A. Benham and get rid of the unsightly thing.” That was more than we could have hoped for, but it wasn’t all. He next called his wife. “Dear, I have three very interesting fellows in my office and I want to bring them home to dinner so you can meet them.” We went to his house, had a very nice lobster dinner and a pleasant visit. In a week or so, an ITT truck appeared with the dish. The boys and I got it put together and mounted on top of the trailer. Then Ken from Gerald Electronics came out and helped get the equipment inside the trailer in good operating condition. Since it was intended to track planes, it was nowhere near ready for satellites. When the trailer was ready to be installed in a location suitable for tracking, it was moved to the middle of a large field about a quarter-mile behind the Physics building. We drove two stakes into the ground and strung a string between them to provide an exact north-south line so the tractor driver could point the trailer as nearly north as could be arranged. He had to maneuver the trailer several times to get it lined up to our satisfaction. We had built a heavy platform for it to rest on so it wouldn’t settle in the ground and perhaps alter its position. It was very interesting and exciting. We had electric, telephone and teletype lines buried from the nearest pole, which was about 300 feet away. One of the interested boys paid the monthly charges for the phone, another paid for the teletype, I paid the electric.
Linkup with NASA
Now we became a significant link in the NASA tracking chain, at least until they got their multimillion dollar system going. Ridgley built a remote control system so we could turn on functions in the trailer from anywhere. For example, I was coming home from Washington one evening and knew we had to track something about midnight. We stopped in Baltimore and by telephone I turned on the heat, and the receivers to give them time to stabilize. At that time it was illegal to use phone lines for private purposes, but we dodged the rules. One afternoon, there was a knock on my office door and a man entered saying, “I’m from the FCC. I have a complaint from the telephone company that you are running equipment by remote control through their lines.” “No, we’re not connected to their lines and are not violating the regulations,” I replied. “Well then, why have they complained?” I explained that we had mounted a coil on the wall under the wall phone in the trailer. When the phone rang, a voltage was induced in the coil which we used to control relays, timers, etc. He wanted to see, so I took him to the trailer and showed him. He was amazed and left saying “I guess we can’t stop you from that!” “No,” I agreed. “We do all this without removing the phone from the hook, so there is no way the phone company could know we’re doing it. If they allowed us to use the line, they could charge and it would be much easier for us to accomplish the task.” I never found out who complained to Ma Bell. Now days it would be no problem. Back in 1936 when I operated my transmitter from the College I had a dedicated line for which I paid, but it allowed control from only one location. The conditions under which this remote system were built had an interesting quirk. Ridgley was driving back to College from his home in Baltimore. Somewhere along the rather poorly lit route 926, he dozed a little and ran full tilt into the rear of a parked truck. Both of his knees were smashed. He spent many weeks in Bryn Mawr Hospital while they were mending. It was during this time that he and I designed the system, on the phone and in person. Then we got tools and parts together and took them to him. He mounted and wired all of the components on a piece of Plexiglas® measuring about two feet square. It was a beautiful piece of work and functioned like a charm. I was heart broken when it was destroyed in a fire! The operating code was simple. Call the number and let it ring once, then hang up. Within a minute, call and let it ring twice. This set two timers running. Then call again and let it ring three times to turn on the heat, or four times to turn on a receiver, etc. Timing was important. To turn things off, let the bell ring four times the second call instead of three and this would set things up for being turned off.
