/Schematics/Radio transmitters/Transmitter and receiver for data on 433 MHz
Schematics of a transmitter and a receiver for data communication (suitable for alarms) on 433 MHz.
The big fat lines on schematics are actually PCB traces with specific dimensions as noted.

TX radi, ali RX ne znam podesiti. LED-ica ponekad zasvjeluca (kad vrtim trimere, a ne zbog
predajnika). TX radi stabilno na frekvenciji 363 i nešto sitno MHz, mogu ga podesiti na oko
450 MHz ali nije tako stabilna frekvencija. Trebalo bi malo smanjiti zav

3M3 = 3,3 Mohm (mega-oma). Isto je i za 3k3 = 3,3 kOhm, itd. itd...

ako sam dobro razumeo ovo moze da se koristi za komunikaciju izmedju dva pic-a. ali koju brzinu
prenosa podrzava? da li su voltaze spremne samo direktno da se poveze na pic? jel neko napravio
ovo hteo bih da pravim pa da znam da li moze tako da se primeni

Pa i nije bas. Treba ti opet neki coder-decoder chip kao sto pise: HT600 recimo. Ovo ti je samo
shema prijemnika koji ce biti u kolima i predajnika koji ce biti u ruci. Na prijemnik ide
dekoder chip a na predajnik koder chip :)
