[1] According to Alan Douglas, a noted radio historian, Rider may have been one of the many engineers that worked on Grebe's top-of-the-line Synchrophase 7 Receivers in 1927.

I believe he designed the audio system of the 1927 Grebe Synchrophase 7, arguably the first hi-fi radio (response to 8 kHz, way ahead of broadcast standards of the day).

He conceived the idea of a tuned analyzer (Chanalyst) and sold the first VTVM using the balanced-bridge circuit that became universal for decades (Voltohmyst).

This was a great opportunity for publishers to capitalize on this as men leaving active military duty were looking to start a career or retrain.

This gave others, like Supreme Publications owner Morris N. Beitman, an opportunity to provide a source of more common models, cutting the size and cost of obtaining service literature.

The television bound volumes became too large and there were many production changes for the models listed that Rider did not always have the opportunity to update or publish supplements.

During his tour of duty at the SSCS, he was given a special assignment at Baltimore to direct the preparation of the prototype for all technical manuals on radar equipment to be used by the army.

After about 20 months at Camp Murphy, Col. Rider was ordered to Ft. Monmouth to organize the Radar Division of the Signal Corps Publication Agency.

This organization was responsible for the preparation of all literature (technical) on all signal-communication equipment procured by the Signal Corps, which covered everything from pigeons to radar.

After about seven months of activity on radar literature, Col. Rider was made executive officer of the entire agency and placed in charge of all operations.

During his army career, Col. Rider received a number of commendations from the Chief Signal Officer and the Adjutant General, the Meritorious Service citation, and in February 1946, he was awarded the Legion of Merit decoration.

With the large interest of restoration and saving consumer "dead technology",[8] the need for Rider servicing literature has grown.
