TX 2 si RX 2 din jucariile Chinezesti .


Recommended Posts

Acestea sunt intalnite in mai toate jucariile R/C marca China . Tx 2 se gaseste in emitator , iar Rx 2 in receptor. Dupa analiza lui Tx 2 am constatat ca poate radiocomanda 5 canale , cu toate ca este folosit de regula de la 2 la 4 Ch , iar cu o alimentare de 12 v se poate mari raza de actiune pana la 150m . Ma intereseaza daca cineva detine documentatie tehnica cu Rx 2 , sau cunoaste echivalenta celor doua circuite integrate .Multumesc :jytuiyu

Multumesc mult ,asta cautam ,ba am gasit si originalul in chineza mult mai detaliat .Cat despre marirea razei am reusit-o cu un vapor pe 40 Mhz ,caruia i-am schmbat emitatorul cu unul de la un elicopter (tot pe 40 Mhz)ce avea antena mai lunga cu 60 cm , tranzistorul final de 400mw inlocuit cu unul de 800 mw , alimentarea urcata la 12 v ( de la 9v) .
