RF Randomization of Lighting

Give me the exact details, and I can get you whatever you need..

I would use LED as the light source, as it doesn't care how often you blink it..

Pretty simple by sounds of it, questions a bit ambiguous. do you have an rf source already or do you need one, dose the signal need to be un modulated or is it modulated at all or is it that the lights need to pulse in time with the modulation. i suppose really i would have an antenna specific to your application, Dipole most likely, then to limit the frequency i would use a hi Q active filter ie, an LC network coupled with a cheap OP amp, then another Rf amp maybe an MMIC to boost up the RF feed that into maybe another filter that is then fed into a comparator, that outputs 5V and is then fed into a PIC which then deals with the flashing of the lights.

If the system only need to operate short distnce and you don't already have a source then that is a whole lot simpler just use a cheap $10AU 433MHz RX/TX module interface both ends a PIC. basically 2 IC's on the RX and 2 on the TX. something like this,

interfaced with say a 16F870 http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1335&dDocName=en010232

AS i say a bit better explanation of the aplication and current setup and i can possible be a bit more helpful.

thank for the reply. Already have RF source(s). The light does need to pulse in time with the modulation. System needs to operate long distance. I just need random flash....is there a simpler approach to this?
