Encyclopedia > Transverter

A transverter is a radio frequency device that consists of an upconverter and a downconverter in one unit. Transverters are used in conjunction with transceivers to change the range of frequencies over which the transceiver can communicate. Radio Wave is also the name of a commercial radio station in Blackpool, North West England. ... A transceiver is a device that has a transmitter and receiver which is combined into a one unit. ...


Amateur radio use

Transverters are mostly found in use in the Amateur Radio Service to convert radio transceivers designed for use on the high frequency (HF) or very high frequency (VHF) bands to radios that can operate on higher frequency bands. A transceiver used in this fashion is refered to as an IF radio, indicating its role as the intermediate frequency in the chain of radio electronics. Common transceiver/transverter combinations include transverters for 50 MHz, 144 MHz, 222 MHz, and 432 MHz designed for use with HF radios, and transverters for 902 MHz, 1296 MHz, 2304 MHz, 3456 MHz, 5706 MHz, and 10368 MHz designed for use with 144 MHz radios. Some transverter units include transmit/receive switching built into the design, whereas other units require external switching. The use of external switching is popular in applications where preamps and amplifiers are included. Many transverters are built into water-proof enclosures for installation on a radio tower or other antenna support structure to get the device as close as possible to the antenna so as to reduce signal loss in the transmission line. Mrs. ... High frequency (HF) radio frequencies are between 3 and 30 MHz. ... Very high frequency (VHF) is the radio frequency range from 30 MHz (wavelength 10 m) to 300 MHz (wavelength 1 m). ... A transceiver is a device that has a transmitter and receiver which is combined into a one unit. ... High frequency (HF) radio frequencies are between 3 and 30 MHz. ... A preamplifier (preamp), as its name suggests, is an amplifier which precedes another amplifier. ... An amplifier is a device which changes a small movement into a larger movement. ... A transmitting tower is, in contrast to a radio mast, a free standing construction, which serves either as carrier for transmitting antennas or directly as transmitting antenna (radiating transmitting tower). ... In biology, antenna (plural: antennae) refers to the sensing organs of several arthropods. ...


Low band use

Transverters can also be used in applications where the transverter frequency is lower than the transceiver frequency. Several low frequency bands are available around the world to Amateur radio operators, licensed experimental stations, and some unlicensed opertions. Transverters for these LF bands generally use HF transceivers as the IF radio. A transceiver is a device that has a transmitter and receiver which is combined into a one unit. ... Low Frequency or LF (sometimes called longwave) refers to Radio Frequencies (RF) in the range of 30-300 kHz. ... Mrs. ... Low Frequency or LF (sometimes called longwave) refers to Radio Frequencies (RF) in the range of 30-300 kHz. ... High frequency (HF) radio frequencies are between 3 and 30 MHz. ... In computer networking, the term transceiver (sometimes abbreviated to TCVR) is a device that performs, within one chassis, both transmitting and receiving functions that is in a common housing, sometimes designed for portable or mobile use, uses common circuit components for both transmitting and receiving which provides half-duplex operation. ...

Transverters, muTek Limited, Scotland - UK (235 words)
Transverters, muTek Limited, Scotland - UK The muTek range of linear frequency transverters enable operation on new bands without the expense and confusion of having to purchase a new transceiver for each band.
These transverters will all operate with the transceivers external A.L.C., or with their own internal A.L.C. This use of automatic level control is unique to muTek transverters, and prevents overdrive of the output stage and hence keeps the transmitted signal clean, even when an over enthusiastic operator 'talks it up' under contest excitement.
These transverters have all the facilities of the 'a' suffix units, except there is no A.L.C. feedback to the transceiver as this facility is very rarely found on modern V.H.F. rigs.
A 28/432 MHz Transverter in Modular Format (1289 words)
Designs and detailed assembly instructions for transverters for various applications, resulting from his activities, have appeared in various publications and have been presented at the VHF Congress in Weinheim.
In practical operation, such transverters are used with the same driving unit; here an additional filter for harmonics and spurious transmissions is recommended.
The 28/432 MHz transverter is divided into two independent assemblies: the oscillator frequency synthesiser and the transmitting-receiving converter.
