    Hello, I am trying to construct a system for time measuring .All is ok, but the problem is that we can not send an analog signal to the RF receiver .We search an option for remote using an analog signal. Until now we have used the RF transmitter 433 MHz and RF receiver also 433 MHz, but there were major problems with them and generally does not work. Does anyone have any ideas how to send the analog signal to 150m?


    Thank you in an advance!

    I think you need to elaborate on what you ar3 trying to do (the big picture) and what problems you are experiencing.

    You don't give much detail (especially needed bandwidth). However, one solution you might want to consider is a current loop, such as a 4-20 mA commonly used to transmit signals in industrial environments.
