style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Vyzkousel jsem zde doporucene
schema s LM317 a optoclenem. Funguje to, ovsem narazil jsem na problem
s pouzitim 10uF kondenzatoru, ktere maji propustit 22KHz od prijimace
k LNB pro prepinani pasma. Po jejich zapojeni se rozhodi vystupni
stabilizator v satelitnim prijimaci a misto 14/18V je na vystupu kolem
12-14V, takze pak nespina optoclen, ale hlavne muze dojit treba
k prehrati vystupniho stabilizatoru
v satelitu...<o:p></o:p></SPAN></FONT></P>
