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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Radio Service Data Sheets were published by various electronics trade magazines back in the early to middle decades of the last century. SAMS Photofact document sets were published on just about every appliance made, and those had much more detail than these briefs. However, for the low-budget repair shop or the do-it-yourselfer, the Radio Service Data Sheets were a godsend. I have been scanning, cleaning up, and posting all the ones I find in my vintage electronics magazine collection. See a complete list at the bottom.

Many fine examples of restored vintage radios can be found on the Internet. The Pilot Model 63 shown above appears on the RadioMuseum.com website.

The power consumption of this set is 70 W.; the undistorted power output is 3 W. If it becomes necessary to realign the set, be sure to reconnect the speaker cable to the receiver after having removed the chassis from its cabinet, before connecting to power line.

To align broadcast band, connect service oscillator to antenna and ground posts, turn range switch to "Broadcast," and align oscillator, interstage and antenna trimmers at 1,400 kc.; and oscillator padder at 600 kc. Repeat procedure. Rock tuning control while aligning padder.

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.
