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...

The Remler "Scottie."

Installing commercial broadcast radio receivers in cars and trucks was a big deal in the 1930s - even bigger than having one in your home. Having an ability to receive the popular shortwave bands was a real sign of success (as was merely owning a car). An advantage to auto radios was not needing an AC-to-DC rectification circuit like in-home models that required at least one additional vacuum tube and a hefty transformer - although many people in non-electrified rural areas had DC radios in their homes as well (the Rural Electrification Act wasn't passed until 1936). In its service instructions, Remler suggested to owners that if poor reception was experienced, the auto should be parked somewhere that a 50-foot secondary aerial could be deployed. I couldn't locate any examples of restored Remler Model 36 radios online, but a few of the Model 26's do appear.

A most unusual feature of this set is the use of a dynamotor in the power supply, in place of the usual vibrator. This unit is guaranteed for one year and needs no oiling or attention of any kind. No rectifier tube is needed. Six tubes are used, all for actual reception. The "hot'" battery lead into the set is completely filtered, making suppressors un-necessary on many makes of cars. A single 1/2-in. hole is needed for mounting. Normally furnished with connections for operation in cars with positive side of battery grounded. This can be changed to grounded negative by reversing two battery leads on the terminal strip on the underside of the set. The dial is calibrated in channels, the addition of one cipher to the markings giving readings in kilocycles. On the right-hand position the short-wave switch gives coverage of the broad-cast band as well as the lower frequency police band. On the left position, the dial covers from 2,200 kc. to 6,800 kc. In some cases the car antenna will not be sufficient for long-distance high-frequency operation. When better results are desired with the car parked, a 50 foot wire, with the far end as high as possible, may be used.

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.
