ABOUT
Radio is often only seen as a medium to transmit music and information through audio to people.
The question that arose was how can we use radio to transmit something beyond sound? This collection investigates a broad range of aesthetic experiments with the broadcasting technology of radio. For us it
is also an inquiry of intervention of this art form. This collection aims to rethink and reconceptualise the radio medium as an explorative aesthetical archive.
The goal of 88,4 DX is to create a temporary autonomous zone of art to communicate artistic compositions for interpretation. Proposing an alternate way to experiencing visual art through the radio.
88,4 is a project made by Nina Michailidou & Caio Vita

SOUND STATION
The radio station 88.4 FM is constantly broadcasting the artwork we have created with the SSTV and FM Transmit- ter. We recorded the SSTV sounds of each one of the im- ages, and made a long play with all of the sounds, so peo- ple can tune in the 88,4 FM and start receiving the images through a SSTV software. Also, it’s possible to apply effects to the broadcast image by a live sound effect app running on the smartphone that is being used as the sound source.
Our SSTV tools
The software we choose to start exploring the possibilities of SSTV and images transmission were the MMSSTV by MM HamSoft for Windows computer and the Android APP Robot36.
Both are able to encode and decode the images into SSTV code to be transmitted via radio.
STEP 2
— Testing the possibilities of the tool
Now that we have learned how the tools, the softwares and the electronic aspect of SSTV and Radio works, we start testing it. First to decide which encoding mode will better suit our needs, second to try to disrupt the tool to create effects that could be further explored as an aes- thetical element for visual art.

After several tests and observations, we have decided that the Scottie DX enconding were the one we are go- ing to use for our project, because of the image quality and speed advantages of it.

TESTING COLORS
We did this experiment to extract the SSTV sound from each color of the color wheel (primary and secondary only). After having the pure sound of each color, we mixed it with Audacity (sound mixing software) to see if we could create new images compositions through the color’s sounds. Then we broadcast this new mixes to get the new image on the SSTV software. The results were not very exciting visually because the software makes one sound for a line, so the only kind of composition possible was one line each color.
TESTING PHOTOGRAPHY
We also want to find out what effect SSTV can cause on portraits and photography. We first run some tests to see how the photography will be received and what noise will be added to it when transmitted via SSTV.
AUDACITY
Because on the SSTV process the image are trans- lated to sound, we thought it was a natural move to explore how editing this sound will affect the received image.
On this test we recorded the encoded sound from the SSTV software for each one of the images, and after that we mixed the sound file using audacity.
With this new mixed sound, we’ve made a radio trans- mission to be received by a SSTV decoder. The result was a mixture of both photos into one image.
Another test made with Audacity was to apply sound effects to the encoded sound, then to transmit this new sound and see how each effect affected the image.
