“Olympic” is a series of superheterodyne radio receivers , the release of the first model of which was timed to the 1980 Olympics, held in Moscow . The radios were produced by the Svetlovodsk Olimp factory, Ukraine . Some models were also produced by the Production Association "Alatau", Kazakhstan .

Content

Features

Powered by 9 V battery .

Medium wavelength range , one or two shortwave ranges , depending on the model.

Lineup and Architecture

All radios in the series contain a single-crystal RF path on an integrated circuit K174XA2 (analogue of TCA440). To select the intermediate frequency , a concentrated selection filter or a piezoelectric filter is used. UMZCH performed, depending on the model, on four or five transistors .

The radios have connectors for connecting a monaural earphone , while the speaker is automatically turned off. The layout of all radios in the series is vertical.

Known models:

Olympic

The first model of the series. The IF path uses a concentrated selection filter. UMZCH on four transistors: KT315B (first stage), KT209B (second stage), KT315B and KT209B (push-pull transformerless output stage) ^[1] .

Olympic 2

It features a design and a modified scheme. A piezoelectric filter is used in the IF path. In UMZCH, two diodes are used instead of resistors to set the output stage mode

Olympic 305

Olympic 401

Olympic 402

The device with a more modern design and two HF bands instead of one. It differs from previous models in the low quality of KPIs. Available in two versions, with UMZCH on four or five transistors. The second option UMZCH uses an additional transistor KT315B to stabilize the output stage ^[2] . ^[3] .

Olympic 403

Radio equipped with a clock with LCD. Unlike previous models, it has only a range of CBs (probably to keep prices at an affordable level, despite adding hours), and is powered by three elements 316. A rare model ^[4] .
