Their use in Indycar racing dates from at least the early 1970s, if not earlier.
May I suggest you post your query in the Nostalgia Forum - I expect someone will know the answer.

Along with the fully enclosed cockpit, the car was the first to use a two way radio from the pits to the driver.
The frequency was that of the common two way radios in use at the time.
Jim said it worked pretty well during practise until when flying down the back straight in practise, he was dispatched to fix a toilet by the local plumbing shop....
It wasn't used during the race....

I'm sure I read somewhere about Leon Duray having a radio way back in 1932, but I don't know if it was two way.

The Sumar was the first to show up. The first full envelope body for Indy cars.
They didn't know anything about aerodynamics at the time, and it was surmised that the packing of air under the front end made the car light and it wouldn't steer well.
It was so bad the car actually qualified without the additional bodywork and looked just awfull without it.
Another streamliner was built by Howard Keck for Bil Vukovich. It was to have a Chrysler V-8 in it but it wasn't finished in time.
The third streamliner was the Belond "Miracle Power Special" driven by Jim Rathmann. It too had an almost full envelope body, but the tops of the wheel arches were open. The car ran with the full aero kit except for the enclosed canopy. It proved to be so hot Rathmann couldn't stand it.
That's the one I was referring to....

In the 90s John Trimbole who had varied businesses was reputedly dictating letters to his secretary while racing at Bathurst in a production car enduro via [I hope] handsfree phone plus had the two way to contend with too.
These days though the radio is really abused. With all the 'strategy' , team orders, plus the crew chief just about telling the driver how to drive the car. And when and if the car breaks down or crashed what to do,, eg turn off the battery isolator! Especially if crashed.
