Some of the kits took advantage of new integrated circuits to allow low-cost construction of projects. For example, the new Signetics NE565 phase-locked loop chip was the core of a subsidiary communications authority (SCA) decoder board, which could be built and added to an FM radio to demodulate special programming (often, background music ...
The editorial board published an appeal to the Soviet electronics industry, proposing they begin producing Radio-86RK kits commercially. [11] By the end of the 1980s manufacturing of computer cases, keyboards and main boards for the Radio-86RK, as well as selling electronic components were carried out by numerous cooperatives.
The FM-5 tuner was offered as was the SCA-80 integrated amplifier in the early 1970s time line. Dynaco's solid-state kits were different from the popular Heathkit products (and Dynaco's own vacuum tube kits) because of their preassembled circuit boards.

Amateur Radio TNCs were first developed in 1978 in Canada by the Montreal Amateur Radio Club and the Vancouver Area Digital Communications group. These never gained much popularity because only a bare printed circuit board was made available and builders had to gather up a large number of components. [specify]
A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the ...
The ZN414 is a low cost, single-chip AM radio integrated circuit. Launched in 1972, the part was designed and supplied by Ferranti , but was second sourced from GEC-Plessey . The ZN414 was popular amongst hobbyists, as a fully working AM radio could be made with just a few external components, a crystal earpiece and a 1.5 V cel l.
Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath Company.
