Navy Studies Effect of High Frequency Fields on Aircraft Electronics

Continental Electronics, Dallas, TX

October 11, 1999

Continental Electronics Corp. (CEC) has won a contract valued at $1.47 million to provide high frequency transmission equipment for the U.S. Navy's High Intensity Radiated Field (HIRF) testing program. The competitively bid contract was awarded by the Navy's Naval Air Warfare Center, Aircraft Division, (NAWCAD), located in Patuxent River, Md.

The purpose of NAWCAD's HIRF testing program is to determine what effects high intensity radiated fields have on the electrical and electronic systems of fixed- and rotary-winged aircraft. One of the program's focus is on radiation fields generated by high frequency, 3 MHz to 26 MHz radio spectrum, which is used for long-distance communications and broadcasting.

CEC's Transportable High Frequency Broadcast Transmitter was selected to create the unique test environment necessary for this research project because of the advanced capabilities of the CEC solid state modulator. CEC's HF transmitters feature an almost infinite ability to resolve power, allowing researchers to tightly control the test environment.

When coupled with CEC's 419 transmitter, the exclusive solid state modulator delivers a custom RF power source that can be varied in small increments from zero to 250,000 Watts of power. Researchers will be able to quickly and easily increase or decrease power to find the exact value that could cause interference to an aircraft's vital control systems.

Ok folks, we need some volunteers for a new flight test program. Experience in ejection seat usage a definite plus.

Just think how many Potholes we could repair in our neglected Parks,like Yellowstone and Yosemite with 1.47 Million of our Tax Dollars,please notice ,You paranoid Idiots in Washington!!

It's hardly new for the military and aerospace companies to be doing research into what effect radio waves have on avionics. If you consider the money "wasted", then which would you prefer: save a few million dollars today and then keep losing new $20M aircraft from interference problems, or invest the money and solve the problem before it happens?

Not to mention figuring out how to harden military aircraft against weapons systems based upon the same technologies in service in not-friendly nations' services.

We know that the Russians have deployed laser-based systems on, for example, their intel trawlers. We saw them use that stuff to almost blind a helo crew a year or so back -- and of course we saw the State Dept. try to bury the poor pilot's claims, but that's another rant.

Now, does anyone want to bring HARP into the discussion? Or GWEN? Are we talking large-scale weather modification? EMF without a high-altitude nuke burst? Population mind control? Any other informed conjecture?
