Augusta Once again Motorola engineers have proven the impossible can be done!
Theyve built a two-way radio the size of a pack of cigarettes and called it the HT-100 model Handie-Talkie two-way radio.
Theyve also cut down the HT-200 Handie-Talkie two-way radio to one-half its predecessors size.
This duo dream come true is the pride and joy of the Motorolans on the Portable Products team and Marty Cooper, director of product operations. The dream first began to take shape back in 1967 when Dave Michalak, manager of Handie-Talkie marketing, suggested that such a unit would substantially enhance our position in the market place. Thanks to the progress in integrated circuits, smaller resistors, transistors and circuit boards, etc., it was decided that there was a chance Motorolas engineering department could come up with a Handie-Talkie two-way radio half the size, or less, than the portable two-way radios then being built.
Marty Cooper himself was sure that it could be done, and the project was undertaken. He assigned Bill Cole, manager of Handie Talkie products engineering, and his staff, to go to work on this project and selected the men needed to work full time on this new line, which would change the entire portable two-way radio market.
Working with Bill Cole on the electrical end of the new unit was Len Bennett, section manager, and eight other top-notch electrical engineers. Next came Dom Errichiello, chief mechanical engineer, and Tom Hutchinson, mechanical engineer, who both worked on the body design of the unit. Responsible to them were many other mechanical engineers who worked on the housing design and other mechanical parts.
During the many months of putting together the two models, a variety of engineers worked on the project. They handled all the different phases needed to make this dream come true.
Len Bennett described some of the problems that were faced and how they were overcome.
Perhaps the main problem we faced was designing, the small printed circuit board to hold all the parts needed, he said. Once we had the board designed we then had the problem of finding a company which would make it for us.
The circuit board is not new to the world, but the design of this type of board was a real challenge for our mechanical engineering department, and with it they really proved themselves.
We also had to develop a new line of transistors to meet our needs. This was done with the help of Motorola engineers at our Phoenix facility. To add to this, a special RF transmitter was designed for the HT-220 model. To add further to the special problems we faced, we also needed to design new batteries for the HT-100 and HT-220 units.
In the case of the HT-100, the battery was built right into the back cover of the case.
Concerning the work that went into the housing and case designing, Dom Errichiello and Tom Hutchinson said it took them and their staff many months of effort to design the housings and cases for the new HT units.
Into the designs of the housings and covers went new lightweight zinc alloys and high impact plastics, said Dom. The use of these high impact plastics and zinc alloys is one of the main reasons the new HTs will be the talk of the communications field. The first of these new units built was sent to New York City for its Police Department to test out in service. The reaction by the New York Police was so great that they immediately ordered 630 of the HT-220 units. When the New York Police Department received their initial units, they were so pleased with the units that they placed an order for 2,200 more of these marvels of the Motorola Communications Division.
