    Default Ajutor - 22 khz

    Va rog, orice date referitoare la semnalul de 22 khz.
    M-ar interesa sa confectionez un "detector" pentru acest semnal, care sa-mi actioneze un releu, in final (nu ma intereseaza ceva specializat, pentru ca nu vreau ca comut vreun lnb, sau ceva din categoria sat).
    Nu am idee despre marimea semnalul trimis de receiver si daca acesta este permanent, sau numai un impuls de o anumita durata.
    Multumesc anticipat.

    Default REZOLVAT!!

    Multumesc oricum..
    Intre timp am rezolvat problema cu un mic montaj cu trei tranzistori.... merge beton.... (m-am uitat in cartea tehnica a lui 4155 si am vazut acolo sa semnalul de 22khz este din belsug, adica 0,6V +/-0,2v)

    Default pentru mariusster

    Nu este nici un secret mariusster, a trebuit sa improvizez un comutator de antena, deoarece in locatia mea actuala nu am piata pentru componente in domeniul instalatiilor de satelit. Pana comandam in tara sau in alta parte, imi trecea cheful..... Oricum, in toamna voi fi din nou in RO si nu se mai pune problema de procurat componente..... toate cele bune...
