How to Combine the 1957 Vintage Radio with RDS Decoder

Guys, you’ve probably heard these words, “Vintage, retro and contemporary” before! However, did you know what the biggest difference between these three magical words is?

Today, we’re going to learn the difference between vintage, retro and contemporary! When someone talking about “Vintage”, it mostly refers to stuffs that was produced between 1920 and 1970. If the collections were produced before 1920, then you might want to call it, “Antique”.

The retro is normally related with stuffs that being produced between the years 1970 to 1990. Hence, the disco can be considered as the mix of vintage and retro! Everything that being made after 1990 is termed as “Contemporary”. Hope you’ve learned the differences and take notes about it!

Let’s back to the main topic. If you owned a very old yet vintage radio, then you might want to modify it a little bit, by combining the RDS decoder onto it!

1957 vintage radio with RDS decoder

Well, it’s a very simple project, where the TDA7330B RDS demodulator and ATtiny2313 microcontroller are the main parts to be included into the project. Basically, the received and decoded RDS text is displayed on 2×16 HD44780 based LCD display with several options, such as:

  • Displaying RDS time,

  • Displaying TA flag,

  • Scrolling 64 characters long RDS text.

Please keep in mind that every time, when you’re connecting the RDS decoder to a FM radio, you have to locate the FM signal detector first. Or, if you don’t know the proper way to find the FM signal detector, you can try to connect it to volume potentiometer’s “hot point”, which is the one pin that is not connected to GND (Ground).
