Home Brew Phone Bug
We loves us some snoppin’ at GadgetReview. We’ve seen a few phones that blur the lines between spying and home security, but this home made device is probably all espionage as it transmits the user’s telephone call via FM frequency. According to Electronics Lab the signal should be good for up to 200’ and broadcast between 88 to about 94Mhz.
