From: budden@trout.nosc.mil (Rex A. Buddenberg) ------- If CNN had a hardwire (landline) to Amman, then the jamming would be extremely unlikely to affect it. In this case, even a satellite throw would probably be largely unaffected. To understand this statement, we need to make a couple points about electronic warfare: When jamming an enemy receiver, technology is not the issue. Power, and intelligence are. The intent of a jammer is to insert enough noise into the control loop (via a receiver) so that control ceases to work, or work reliably/predictably. Since receivers are tuned to receive specific frequencies, it does no good to jam them with RF energy outside those freqs. In the case of Baghdad, I strongly suspect that we know what freqs to jam to a considerable level of confidence and precision. The weaponry is largely Soviet and recall the note about the Soviets trucking the Dutch Patriot battery to Turkey... So we probably know every technical detail about the AA radars, including any war reserve frequencies. This means that the offensive jammers can be tuned to concentrate their jamming energy in very specific frequency bands and not waste it elsewhere ... like in CNNs frequency. Rex Buddenberg -------

Talk about 'harmonics' - a frequency phenomena. At Hohenfels Training area in Germany - there was one set of frequencies that always seemed to be "jammed" by a 'voice jamming' system. Until you listened carefully and had a linguist nearby - it was a Czecheslovakian Taxi Cab company.... ------------------------------ We also had some "unattended ground sensors" (UGS). The crystal frequency was set at the plant in Texas. Unfortunately, we weren't allowed to use them in Germany - the frequency was set on German TV!!!??? ----------------------------- Go figure.. mts
