Remember, radio waves are a form of electromagnetic radiation that is emitted by chrged particles. UFOs would be charged mass bodies that would emit
electromagnetic radiation(light) that would register far deeper into the electromagnetic spectrum, hence UV and Gamma radiation.
SETI isn't looking for UFOs. They're looking for signs of interstellar communication and using radio telescopes is not as "dumb" as you might
think. They're scanning on 1420 MHz, the resonating frequency of hydrogen, the most common element in the Universe. Therefore, they reason, it is
logical that Extraterrestrials would use this frequency as the carrier signal for their message, through Amplitude Modulation (AM). This is exactly
what the WOW signal was showing. The famous sequence 6EQUJ5 is not a message, it shows the amplitude modulation of the signal on the 1420 MHz band.
The E for example means that this part of the signal was 30 times "louder" than what the normal cosmic background noise on 1420 MHz is. So what
6EQUJ5 showed was an amplitude modulated hydrogen signal - therefore it is conceivable that it is an artificial signal.
Besides, Harvard and Princeton are now installing optics to scan for Laser emitted communication, while the MIT is trying to figure out how we could
detect artificial Gamma ray pulses, this is however still beyond our technological horizon - imagine that an ET civilization could pack as much as
1×10^18 bits of information into a 2 millisecond gamma ray pulse. That's all the information in libraries and on computers in the world, plus all
information of Earth's biosystem, Genes and Memes.
The biggest problem SETI has is lack of funding - not a lack of smart people.
