In 2007, the US Department of Defense projected that satellite demand for the next 10–13 years would increase much more rapidly than the government could build and launch its own satellite systems, making hosted payloads on commercial satellites an attractive alternative. [citation needed] Hosted payloads can support a variety of missions.
Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.
The PhoneSat bus was used in several other projects. The follow-on project, Edison Demonstration of Smallsat Networks (EDSN), was an 8-satellite constellation of 1.5-U cubesats [8] based on the PhoneSat 3.0 architecture. However, EDSN did not make orbit, launching on the failed Super Strypi mission in November 2015. KickSat also used PhoneSat ...
A satellite modem is not the only device needed to establish a communication channel. Other equipment that is essential for creating a satellite link include satellite antennas and frequency converters. Data to be transmitted are transferred to a modem from data terminal equipment (e.g. a computer).
A radio transmitter design has to meet certain requirements. These include the frequency of operation, the type of modulation, the stability and purity of the resulting signal, the efficiency of power use, and the power level required to meet the system design objectives. [1]

The wire antennas used with crystal receivers are monopole antennas which develop their output voltage with respect to ground. The receiver thus requires a connection to ground (the earth) as a return circuit for the current. The ground wire was attached to a radiator, water pipe, or a metal stake driven into the ground.
