About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...

Crosley Model 120 Senior Superheterodyne (Pliodynatron) Chassis Radio Service Data Sheet, June 1931 Radio-Craft - RF CafeWestinghouse's motive for dubbing the Model WR-8 the 'Columnaire' is apparent when you see a photograph of it. This model also had a -R version with remote control. The remote, though, has a cable attached to it; it's not wireless like today's remotes.

The fundamental circuit of. these receivers is the vVR-5 receiver chassis and power pack shown in Data Sheet No. 29. The model WR-6 is a highboy; its circuit is the same as used in the WR-S, except as modified for tone control. The Model WR-7 is similar to the model XR-6, except as modified for an electric phonograph.

Westinghouse "Columnaire" Models WR-8 and WR-8-R (Remote Control)

Models WR-6-R and WR·7-R are the same as the respective WR·6 and WR-7 chasses, except as modified for remote control. The Model WR-8 uses the same chassis and power pack as the Model WR-6, only all electric clock and the cabinet distinguishing it as the "Columnaire;" the remote-control model being coded as the Model WR-8-R.

Westinghouse "Columnaire" Models WR-8 and WR-8-R (Remote Control) Radio Service Data Sheet, June 1931 Radio-Craft - RF Cafe

The "Columnaire" Model WR-8 is, except for the cabinet, the same as the Model WR-6; while the Model WR-8-R receiver chassis and power pack are almost identical with the Model WR-6-R. Leads for the synchronous electric clock are shown and, (in dots) the leads for the remote control attachment. The primary of T3 connects to the 110 V, line; the secondary output is 23 Y.

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.
