Multronics, Inc. was the principal sub-contractor for Project Jenny (AKA Project 15, AKA Blue Eagle), the flying radio/TV station aboard Navy Constellation aircraft, that played a crucial role in both morale and propaganda broadcasting during the Vietnam War.
Project Jenny was supervised by the mercurial Capt. George Dixon, later a corporate officer at TMC. Multronics actually did most of the serious engineering to enable the flying broadcast studio, a project that many thought was impossible. This included the design and test of a trailing-wire antenna tuner (no-one was sure what would happen when driving this antenna at 10KW, with no counterpoise!) and a transmitting antenna coupler that allowed the HF and LF transmitters to share the trailing wire.
I was privileged to interview John Showalter, a junior engineer at Multronics in the early 60's, who became Dixon's technical go-fer on Project Jenny. John had many interesting adventures during the project, some of them reported on the Project Jenny page. John very kindly made me a gift of the manuals and course-work shown below.. thanks much, John!
