I bought 2 or 3 of these https://www.sparkfun.com/commerce/product_info.php?products_id=7816 with different frequencies. They work flawlessly on the mini PCB I made when powered by my power supply but nothing at all when powered by a 9 volt. I made a pcb with a receiver of one frequency and a transmitter of another frequency for 2 way communication. each receiver/transmitter pair is powered by a single 7805...Im not an expert reading data sheets so maybe someone can tell me whats wrong. Im assuming the 9 volt is incapable of powering a 7805 but maybe im wrong...please church me up if possible
THANKS
