Well, a "choke" is a fairly simple device consisting mainly of capacitors and inductors and the purpouse of which is to short out the RF radiation before it gets detected in your phone. It can be effective sometimes, and totally worthless at times. > Perhaps the basic idea is to find the person operating the transmitter > and choke him. Aaahh, that is why you can always read in ham radio magazines about angry neighbours coming to the local ham to complain about RFI and TVI (Radio Frequency Interference and TeleVision Interference) BEFORE they even have gotten the transmitter out of the box. Yes, that seems quite common. IDENTITY: Anvin, H.
