Although originally designed for telephone usage and later adopted for computer networking, the modular connector has been used for microphone connections extensively on modern amateur radio equipment, including models from the three major manufacturers (Icom, Kenwood, and Yaesu), but primarily used on mobile radio equipment (designed to be ...
WIRES II - Yaesu did terminate WIRES-II service on Saturday, September 30, 2017 at 06:00 UTC. They suggested in the future, to use the WIRES-X Internet linking system. [2] [3] WIRES-X - Supports the C4FM digital and the voice technology. It enables high sound quality by repeating C4FM digital data as it is via the Internet.
The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price ($670.- at its 2001 release). [ 3 ]
A pair of plugs, known as "GA" or general aviation plugs. 1/4-inch plug for audio (PJ-055), and a 3/16-inch plug for the microphone (PJ-068) U-174/U (Nexus TP-101), U-93A/U (Nexus TP-102), and Nexus TP-120, also known as US NATO, commonly used in helicopters, with a diameter of 0.281 in (7.1 mm) and length 0.761 in (19.3 mm).
The microphone generates its own voltage and needs no power. Devices that use a self-powered microphone: usually a condenser microphone with an internal battery-powered amplifier. Devices that use a plug-in powered microphone: an electret microphone containing an internal FET amplifier. These provide a good quality signal in a very small ...
Microphone interconnections are therefore a common application for a balanced interconnection, which allows the receiver to reject most of this induced noise. If the power amplifiers of a public address system are located at any distance from the mixing console , it is also normal to use balanced lines for the signal paths from the mixer to ...
GMSK using a sound card - this method uses a computer sound card to generate GMSK modulation and de-modulation. The primary software for this method is developed by Jonathan Naylor. An example of a repeater system using this technique is the addition of D-STAR to the Yaesu DR-1X repeater by attaching the UDRC and a Raspberry Pi computer. [28]
A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.
