Manufactured by R. L. Drake.
In 1979 Drake introduced the original version of the R-7, in the initial plans it was a receiver with analogue display covering the amateur radio bands. Soon the digital display became standard, and with the number of options integrated in the standard set, the catalogue price rose from US$1295 to US$1800:
It is uncertain whether copies of the original R-7 without the option of digital frequency display were actually sold, but the majority of R-7s in circulation are probably the version R-7A with continuous frequency coverage and digital frequency display.
For description see the version R-7A equipped with the options.
The set is equipped with semiconductors.
