Gerald Poaps' Scrapbook

Gerald E. Poaps left the Royal Canadian Air Force in 1947 and became the ninth member of the Radio Propagation Laboratory, which was housed with the Royal Canadian Navy in the old A Building on Elgin Street in Ottawa. He has loaned us a collection of photographs which he made during his career with the DRB, DRTE and CRC, and we are showing a few of these photographs to indicate to others the types of equipment worked on and developed through his career, and the types of projects undertaken. Gerald retired from CRC in 1975.

Here is the note we received from Gerald in April 2002:
"I joined DRTE Radio Physics laboratory on December 10 1948. The group of nine personnel consisted of the following staff: Frank Davies, Rita Richard, Jim Scott, Jim Cox, Amour Warwick, Clair McKerrow, Jim Scott's analyst named Dave - I can't remember his last name, and the machinist named McQueen. Six of us had office space in the Armed Forces Headquarters Building A on Elgin Street Ottawa. Warwick, McKerrow, and McQueen were located in the machine shop building located on the Rideau River near the arboretum. About 1950 a small building was constructed beside the machine shop and the Radio Physics staff moved in. I have a photograph of the building taken in 1951. At this period in time, additional staff were employed. To name a few: Jack Meek, Dr. Percy Field, Marion Phillips, Ms. Fowler, Everett Stevens. An early phone book would provide a complete listing. I believe that I, at 87, am the oldest living member of the original RPL staff."

The RCAF was having troubles with deep fading at their relay site on Highway 7, near Eagleson Road to the west of Ottawa. Gerald was given the job of making radio refractive index measurements, using a modified meteorological radiosonde. Shown above on the left are the radio repeater bays, and the rack on the right holds his test and recording equipment.

A hydrogen-filled baloon is launched to carry the radiosonde aloft, much as is still done today all over the world.

There was a contest between the National Research Council and the Defence Research Board for the development of a power supply which could operate for months at a time, unattended, at temperatures down to -50C. Shown here are Gerald's truck, trailer carrying twin diesel generators and another trailer carrying a fuel tank.

Dr. George Jull became interested in the HF fading performance of orthogonally polarized signals. This photo shows crossed dipole antennas.

The receiver racks for the dual polarization experiment. The box on the table at the left is a paper tape punch which was used to record data from the experiment. Punched paper tape was commonly used well into the 1970's.

In the 1950's, people were beginning to experiment with VHF and UHF to overcome the often unreliable aspects of HF communications. This antenna was made at DRTE. It consisted of plywood sections covered with wire mesh. This particular installation was at the Quiet Site, and was in support of studies by Dr. Don Hay.
