Re: Good article, but not entirely accurate
Steve Knox, Tomislav, et al.,
I'm deeply disturbed to learn that there is some one intentionally jamming emergency communications channels, and what's worse, only when there is an emergency occurring. I had originally read these comments about four hours ago, and only just now had the chance to reply. Your second post, Mr. Knox, makes me fear that one of my suspicions is correct; the perpetrator is somehow receiving information about the investigation. I must surmise that he or she is either currently involved in the agency or agencies using those emergency channels, or has a person or persons working in or with this agency or agencies, feeding information to the person doing the transmitting.
It seems to me that the most simple way to get around this problem would be to switch to a different type of transmission. The most effective solution would be going to fully encrypted digital voice communications, but budgets, and most probably legislation, would prevent that. A less expensive alternative would be switching from analog to digital (if you haven't already), or switching to a trunked system. Although, I should point out that even fully encrypted digital transmissions can fall victim to something as simple as a third party pressing their transmit key at just the right time, even if all they're using is an analog transceiver.
It seems to me that the best bet in finding this bozo would be if the agency or agencies could set up, at separate locations, DF receivers (receivers that also show direction) capable of logging the direction a transmission comes from, and the date and time. Then, after a case of illegal transmission during an emergency, those records can be checked against dispatch log tapes and interviews with the personnel involved to rule out the locations of legitimate transmitters. At that time, only the illegitimate transmitter's location will remain.
If some how the agency or agencies involved have the budget to do this - and I hope that they do - either a), the perpetrator will catch wind of this plan, and stop transmitting, thus solving the problem, or b) will continue to transmit either because he/she was not aware of the plan to locate him/her, or he/she wants to be caught.
I'm guessing that the agencies are police and fire/EMT, and that it's either at the local or county level, and that a local or county sized budget is why a solution like this has not been tried yet.
I sincerely hope that the perpetrator is caught.
