I'm glad you like it.RF modules range depends on multiple factors and cannot be controlled upstream. Buildings, interferencies, receiver shielding, makes a difference. My statement "The range can be also reduced" comes from empirical tests. I have observed that increasing transmission speed the range decreases. In my case, changing Wirtual Wire speed setup from 1000 to 2000 range decreases approx. from 40 to 4 mt., in the open air. First time i used these RF modules, i was not satisfied about range covered. Telecontrolli enginner told me that my receiver PCB needed of more shielding, so i soldered a metal plate connected to GND on receiver module. He said also that, with a good shielding, these modules can communicate 100 meters away.
thanks for your concern.I've watched tv programme and just never realized stolen sheeps could be so prevalent. ...the thieves are very fast to steal a flock of sheeps!
