does any one knows an optimal remote-control decoder algorithm. I use PIC12c505 as the encoder and having touble with signal quality for more than 1 meter from the receiver (e.g. i use standart 433MHz receiver). thanks
 

Try to use Holtek IC's HT12E / HT12D. Very simple to use and you don't need mC at all. I use them with standard 432/433 MHz modules up to 1000m.
 

Try using the LM 1871 (RC Encoder+Transmiter) and the LM 1872 (RC Receiver + Decoder)
These chips make a complete 6 chanels Radio Control sismtem en the freq range from 27 mhz to 49 mhz whit a field strength of 10,000 uV/meter at 3 meters.
 

sorry for languge

In the Magazine ELEKTOR you have circuits with/less uP for it.Try it is very interesting
 

Hi!

The LM1781 , 1782 are obsolete products. Can me help somebody , where can I buy these?

Regards:Cipo
