A transceiver allows you to receive and transmit radio signals, and the company Yaesu offers different types of transceivers and radio equipment. The Yaesu FT-757GXII is a type of amateur high frequency transceiver first released in 1983. This model replaced the FT-757GX standard model, and it came with improved features, including a better computer-aided transceiver (CAT) system. This model is no longer available, but you can still purchase replacement parts from online vendors.
Features
The FT-757GXII comes with a duct cooling system to keep the transceiver from overheating. This system includes an exhaust outlet, cooling fan and heatsink fan for capturing heat inside the device. This transceiver has an unlimited clarifier range, and it has a 100 watts output in FM, SSB and CW. It only has a 25 watt output on the AM frequency. It also features a noise blanker to reduce noise interference, Morse code keyer and image frequency (IF) shift. It also has dual variable frequency oscillators (VFO). This transceiver also comes with 10 memories.
Specs
The range of this transceiver is 524 ft to 32 ft. Its dimensions are 9.4 inches wide by 9.4 inches deep by 3.7 inches high, and it weighs 11.5 lbs. The audio output impedance is between 4 and 16 ohms, and the maximum audio power output is 1.5 watts. The IF rejection is above 70 decibels on all frequencies, and this refers to the ratio between the wanted input frequency and the frequency created by the image frequency.
Electrical/Accessories
You must use a 13.8 VDC at 19 amp power supply. The receiver uses up to 2 amps of power, and the transmitter uses up to 19 amps with 100 watt output. This transceiver comes with a RCA phono plug, a three-pin phone plug, a fuse and a DC cord.
Controls
Controls located on the front of the machine include the "Power" button, "Band/Channel" button and the "Tuning" knob. It has two AF controls. The inner control increases or decreases the receiver volume, and the outer control manipulates the IF and radio frequency (RF) amplifier gain. The receiver also has a "Notch/Shift" button that starts or stops the IF notch filter, and a "Scan Mode" button that scans through different frequencies. The VFO control buttons are also located on the front, including six keys to transfer data and frequencies between the 10 memory buttons and the VFO buttons. The "Delay" control is located on the back of the unit, which allows you to set how long the delay is between when someone stops speaking and the receiver reactivates.
