Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. [1] ALE is a feature in an HF communications radio transceiver system that enables the radio station to make contact, or initiate a circuit, between itself and another HF radio station or network of stations.
A remote starter is a radio controlled device, which is installed in a vehicle by the factory or an aftermarket installer to preheat or cool the vehicle before the owner gets into it. [1] Once activated, by pushing a button on a special key chain remote, it starts the vehicle automatically for a predetermined time.
The most common AN/ARC-5 receiver remote control box is the C-38/ARC-5, which allows control only of audio volume of the VHF and MF/HF receivers. No power, mode, or frequency controls are present. The C-38 also has controls for the R-4A homing receiver.
The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios. It replaces the earlier AN/PRC-150 , with a smaller form factor and lighter weight than its predecessor, and being capable of 4th Generation Automatic Link Establishment (4G ALE), achieving data transmission speeds up to 10 times faster.
The ARC-190 is a military HF radio that operates between 2-30 MHz and transmits at 300+ watts.It features a dual heterodyne receiver/transmitter that uses IF frequencies of 97.8 and 1.8 MHz, an antenna coupler that is pressurized to 7±1 PSI with dry nitrogen (air) which (1) prevents high voltage arcing, (2) prevents corrosion, (3) provides a uniform cooling medium, and one of various controls ...

Remote control military applications are typically not radio control in the direct sense, directly operating flight control surfaces and propulsion power settings, but instead take the form of instructions sent to a completely autonomous, computerized automatic pilot. Instead of a "turn left" signal that is applied until the aircraft is flying ...
The fact of connecting a ham radio station to a telephone network exists from the beginning of the ham radio operators, even commercially, as the case of Carterfone [2] (with lawsuits filed by the companies to which it was connected [3]), but it was not possible to talk about mobile telephony until the arrival of the cellular network AMPS, initially using a car phone as the cellular terminal ...
