Set for radio amateurs '' Quartz-19 ''.
Radio and electrical constructors, sets.ComponentsThe set for radio amateurs "Quartz-19" was produced presumably since 1982. The kit is intended for assembling a 1 Hz crystal oscillator. The set contains all the parts, except for the printed circuit board. The same generator, already assembled on a printed circuit board, was produced in the "Quartz-20" set.
