VEF Spidola (, ) was the first mass-produced transistor radio with short wave band in the Soviet Union (tube short wave receivers were produced for many years before). It was manufactured by the VEF factory in Riga, Latvia, since 1962. A small series under the name "Spidola" (Спидола ПМП-60"ПМП-60" stands for Полупроводниковый Малогабаритный Приёмник выпуска 1960 года, or "Semiconductor Compact Receiver, production year 1960") had been manufactured since 1960."Spidola" "Transistor radios of the Soviet Union 1961-1996" It was named after the fictional witch Spīdola from the Latvian epic poem.

History VEF engineers Uldis Briedis and Jānis Cerps initially worked on a portable transistor radio on their own initiative, outside of working hours. They assembled their prototype using the enclosure from an existing tube-based receiver named "Tурист (Tourist)". Their prototype covered the broadcast, medium-wave, and shortwave (16 to 50 meter) bands. By the late 1950s, VEF was facing a surplus of unsold tube-based radios, and factory management saw the engineer's project as a potential lifeline for the factory. A small batch of the first radio under the "Spidola" brand—the PMP-60 (russian abbreviation for "compact semiconductor receiver", also known as PMK-60)—was released in 1960. The design was created by Ādolfs Irbītis, while Jānis Cerps came up with the name. Due to bureaucratic delays and technical challenges, mass production of the first model did not begin until 1962, but continued until 1965.

In many cases, the Spidola was used to listen to Western stations, such as the Voice of America, Radio Free Europe/Radio Liberty, BBC, and Deutsche Welle. The criminal prosecution of at least one Soviet dissident involved confiscation of the Spidola as an "instrument of crime," but without specifying the "crime" committed with the confiscated Spidola."Processes of past years" (Chronicle of Current Events, issue 33)

The word "spidola" was a genericised trademark for "transistor radio" for a long time in Russian(russian) «Спидолу» писали с маленькой буквы…//Телеграф, № 56 (294) от 22 марта 2004 (other synonyms included "transistor"). In Chukchi language, the word "spidola" is generic for any portable transistor radio.http://db.chgk.info/files/spb06.1-a.html Чукотский язык. - Чукотские форумы
