i want to send some signals on the 433 MHZ band.
Now i've bought a device (CDT-88) and it says 315/433 MHZ
(RF Wireless Transmitter Module 315 of 433,92 MHz CDT88)
after some searching i see a lot of sites where that frequency combination is used together.
Now i wonder: what does that mean? do i send at both frequencies?
What you might have guessed: it does not produce the desired result yet :-)
does it matter when i send at 315 mhz and the receiver is at 433? (it sounds like a yes, but i'd better be sure)
