Unfortunately, though the IC that I used for this circuit can only go down to about 38 ms of delay, however I researched more and found one that could do anywhere between 0.5 ms of delay and higher. The submit illustrate a fairly easy homemade RF signal jammer circuit that can be employed for jamming any RF signal within a radial choice of 10 meters. My cell phone does produce a similar echo all by itself sometimes, although longer than 300 ms and not loud enough to disrupt my conversations completely.
