Sparton 7−46 console radio with Knight−Kit Star Roamer multi-band receiver sitting atop.

RF Cafe visitor Jim F. writes occasionally to fill me in on some details of his experiences with some of the vintage radios that I post schematics and parts list for. In this case it is the Sparton Model 7−46, on which he fondly remembers as a boy listening to the Cassius Marcellus Clay, Jr. (aka Mohammad Ali) fight during the 1960 Summer Olympics in Rome, Italy. "The party line telephone sat on top of it," recalls Jim. He sent a photo of a 7−46 cabinet and a radio Star Roamer multi-band receiver which was a Knight-Kit. This schematic and parts list set from the February 1947 issue of Radio News magazine includes not just the Sparton 7−46, but also the 7−46PA, 8−46, and 8−46PA radios. There are still many people who restore and service these vintage radios, and often it can be difficult or impossible to find schematics and/or tuning information. A running list of all data sheets is kept to facilitate a search (see below).

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
