am acasa schema dar nu gasesc site-ul. exist ceva in revista tehnium ( nr.12/'90 ) legat de statia SIGNAL 1 si se putea modifica exact pentru ce aveti noi nevoie. TX (transmitatorul) are un tranz 2SC1815 in baza caruia se afla un quart de 27,145Mhz ,iar RX (receptorul) are un 2SC380 si doua 2SC1815 (comanda un releu) si se alim (ambele montaje ) la 9V dar asta nu este o problema . se pot face o multime de modificari .sau cu un bistabil comandat de un receptor in IR + un filtru (la receptor) si un mic oscilator in IR la emitator cu ceva CI CMOS SMD
