By analogy, the measurement cable is a crystal radio (non-discriminating receiver) representing all the radio receivers that might suffer interference from dirty emissions. Though called an SWR Meter, a low measured ratio indicates not only good match, but also clean A3, F3, or G3 emission without excessive harmonics nor spurious (out-of ...
An antenna analyzer measuring SWR and complex impedance of a dummy load. MFJ-269, MFJ Enterprises Inc. An antenna analyzer or in British aerial analyser (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications.

[24] [25] [26] Introduced in the year 2000, the radio was known for its "all-in-one" functionality. It can transmit on all amateur radio bands between 160 meters and 70 centimeters, with the exception of the 1.25 meters band, and the "X" model also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS ...

Several satellites with amateur radio equipment on board have been designed and built by universities around the world. Also, several OSCARs have been built for experimentation. For example, NASA and AMSAT coordinated the release of SuitSat which was an attempt to make a low cost experimental satellite from a discarded Russian spacesuit ...
In future seasons, Alabama has already scheduled home-and-homes with heavyweights and non-cupcakes like Florida State (2025-26), Ohio State (2027-28), Notre Dame (2029-30) and Georgia Tech (2030-31).
An amateur radio propagation beacon is a radio beacon, whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and ...
