I think this requires that you put all this in perspective. Your truck is emitting more electromagnetic waves than your TPMS emits. You have radio station blasting 50,000 watts of radio frequencies all across the AM band. You have cell phones and towers covering their band and you have CB radios frequencies coming from around the world. All from sources that have no idea that someone is blasting where you are driving. The answer is no! Anyway you would have to take off your sending units to stop the radio frequency because that is where it is emanating from.
Question, knowing what you know do you really think that a blaster would depend on that warning sign to keep from being blown up? Do you think that some teenaged girl who is driving down the road steering her car with her knee while texting is even paying attention to that sign. Do you think that 18 wheelers who have TPMS and repeaters stop and unscrew their sending units.
The warning sign is obsolete and is a holdover from many years ago, and there is no practical reason to put it out on the highway.
And if the blasting company has not gone digital and they are still on radio frequencies then they are taking their lives in their own hands. Plus that their insurance company would not insure or bond them if there was a possibility that a passing vehicle could set off a detonator. You would be stopped miles from the blasting area and inspected by a device that could detect radio frequencies emanating from your vehicle. There would be no honor system yellow warning sign to warn you. I ramble but you get the idea.
I have a question for TST. When I see a roadside warning to turn off two-way radios, rf devices and cell phones due to blasting in the area, do I need to turn off my TST system, and what about the repeater installed on my trailer, is it of concern for this warning?
