The Kenwood TS-820S is a model of amateur radio transceiver produced primarily by the Kenwood Corporation from the late 1970s into the 1980s; some were produced by Trio Electronics before Kenwood's 1986 name change). The transceiver's predecessor was the TS-520, which began production a year earlier.
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.
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.
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 ...
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 ...
The AN/PRC-150(C) Falcon II Manpack Radio, is a tactical HF-SSB/ VHF-FM manpack radio manufactured by Harris Corporation. [1] It holds an NSA certification for Type 1 encryption . [ 2 ] The PRC-150 is the manpack HF radio for the Harris Falcon II family of radios, introduced in the early 2000s.
The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25.It differs from its predecessor mainly in that the PRC-77's final power amplifier stage is made with a transistor, eliminating the only vacuum tube in the PRC-25, as well as the DC-DC voltage converter used to create the high plate voltage for the tube from the 15 V battery.
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.
