[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 ...
The AN/PRC-10 is an American VHF portable radio transceiver, introduced in 1951 [1] as a replacement for the wartime SCR-300 set. The AN/PRC-8 and AN/PRC-9 sets are basically the same but cover lower frequency bands. It remained in service with the American military until the mid 1960s when it was replaced by the transistorized AN/PRC-25 set.
Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
The Gonset Communicator was a series of vacuum tube VHF AM radio transceivers that were widely sold in the 1950s and early 60s. They were designed by Faust Gonsett and manufactured by the Gonset Division of L. A. Young Spring and Wire Corp. [ 1 ] Models were built for amateur radio , aircraft radio and U.S. Civil Defense use.
They also sold specialty test equipment for the ham radio market, including signal generators and grid dip oscillators. [ 3 ] First located at 84 Withers Street in Brooklyn , New York , [ 4 ] and later at 33-00 Northern Boulevard in Long Island City , [ 5 ] EICO produced hi-fi products in the early 1950s to the mid-1960s with a line of tuners ...
Marine VHF radio is a worldwide system of two way radio transceivers on ships and watercraft used for bidirectional voice communication from ship-to-ship, ship-to-shore (for example with harbormasters), and in certain circumstances ship-to-aircraft.
Comparable to the American SCR-508 tank radio, which covered a similar frequency range (20-27.9 MHz) at 25 watts and the SCR-608 artillery variant (which operated in the 27-38.9 MHz frequency band) The major difference between German Army tank sets and US Army tank and artillery sets was the American use of FM for the high-HF/low-VHF bands.
In a sound wave, the complementary variable to sound pressure is the particle velocity. Together, they determine the sound intensity of the wave. Sound intensity, denoted I and measured in W·m −2 in SI units, is defined by =, where p is the sound pressure, v is the particle velocity.
