Acousticon Radio-Wonder Model RT-1 "Radion"

The Acousticon Radio-Wonder, Model RT-1 or "Radion" attachment was a small AM radio tuner that could be plugged onto the right side of various models of Acousticon hearing aids including the A-90M and the A-100 Imperial models (both 1947), the A-150 (1949) and the A-152 (1950). Attaching the "Radion" to these hearing aids, turned them into 3 tube personal AM radios—a first for hearing aids!

In addition, the "Radion" could also be plugged into Acousticon hearing aids designed for the Super Radion, including the A-120, A-130 and A-145 (all made in 1948) and the A-160 (1949).

These hearing aid models were equipped with two input connections on the right side of the hearing aid. The two pins on the left side of the "Radion" plugged into these connections.

The "Radion" itself was a simple tuner with a sliding tuning dial on the front. The tuning range was from 550 kHz to 1500 kHz.

It came equipped with two long wire antennas that plugged into the top (black cord on the right). It is shown here attached to the Acousticon A-100 hearing aid (left). The other end of one antenna wires could be plugged into the electrical wall socket to use the electrical system as a super-antenna.

The other antenna wire had an alligator clip on it so it could be attached to anything metal to make an even better antenna.

The following year (1948) the "Radion" was superseded by the Super Radion (click the "Next" button to see this model) which featured a vacuum tube detector and pre-amplifier in its circuitry making it a much more powerful tuner.

The "Radion" could be considered one of the first "Walkman" radios.
