Lower frequency longer wavelength energy may cause heating, but is not sufficient to change the atomic structure of atoms. However, higher frequency radiation gamma rays, x-rays, etc. This is why it's referred to as ionizing radiation.
The practice of ham radio operation began mainly as a hobby for many people, but there are also many professional uses for the technology, with operators providing many services such as emergency communications. Through the advances of the Internet, lasers, and microwave transmitters, today's ham radio operators are making contact with people in greater numbers than ever before. In fact, the use of a ham radio can enable a private citizen to have one of the most powerful wireless communications devices possible.
In electronics and telecommunications a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating currentwhich is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radiosuch as radio and television broadcasting stations, cell phoneswalkie-talkieswireless computer networksBluetooth enabled devices, garage door openerstwo-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons.
Microwave frequencies are often used for fixed point-to-point communications circuits in cases where wire or fiber optic lines are not possible or desireable. Uses include long distance telephone, studio-transmitter links STLcell site backhaul, and backhaul for remotely controlled repeaters, base stations, and voting receiver sites in land mobile radio systems. Microwave communications systems are generally required to use highly directional antennas such as dishes or horns to reduce interference to and from from other stations and maximize frequency reuse.

This project is an entry level 47 GHz transverter. The design philosophy and construction are presented in detail. The components are the minimum equipment needed to put a transverter on the 47 GHz band.
Well as the title suggests would it be possible in an emergency and tools permitting to be able to in an hypothetical emergency take apart a common micro wave oven and turn it into a microwave transmitter. Kitchen foil and the like. I think it may be possible to use the microwave as a carrier wave for a digital signal. The answer undoubtedly lies in the eternal question:.
The frequencies kHz are used for maritime communication and navigation and for aircraft navigation. Carrier frequencies of to kHz are assigned at 10 kHz intervals. Frequencies: kHz Wavelengths: - m Quantum energies: 2 - 6 x 10 -9 eV.
