About this product

Product Information

The Icom IC-720a radio transceiver supports AM, CW, and SSB band modes. Offering a different power output for each mode, the ham radio covers nine amateur HF bands, including the 1.8 to 2.0 MHz, 3.5to 4.1 MHz, 6.9 to 7.5 MHz, 9.9 to 10.5 MHz, 13.9 to 14.5 MHz, 17.9 to 18.5 MHz, 20.9 to 21.5 MHz, 24.5 to 25.1 MHz, and 28.0 to 30.0 MHz ham bands. In addition, the Icom IC-720a radio transceiver uses a quad conversion receiver with a general cover frequency range from 0.1 MHz to 30 MHz in 30 1-MHz segments. Manufactured in the 1980s, the Icom IC-720a radio transceiver’s hefty yet small size offers portability in a ham radio, and its cast-aluminum chassis helps protect the delicate internal components. Unlike more modern board-type layouts, the IC-720a features a modular design, sometimes making it an interesting challenge to tune properly. Some of the controls and switches include the RF power control, which allows you to turn on or off the built-in RF speech processor; the mic gain control, which allows you to adjust the modulation level of the microphone; and various gain controls for controlling the gain level when receiving. In addition to the various controls, the Icom IC-720a radio transceiver also offers various switches, including the transmit/receive switch, allowing you to switch between one mode or the other; a VOX switch, which allows for the switching between transmitting and receiving through use of a voice signal; and tune rate select switch, which gives you the option of switching between 10 Hz and 100 Hz steps on the tuning knob. The small venire marks signifying 1 KHz steps on the rotary tuning dial light up after pushing the tuning speed button, allowing you to use the rotary dial to quickly scan the frequency range to get within the specific band you desire. The Icom IC-720a radio transceiver also comes with two variable frequency oscillators, letting you receive on one while transmitting on the other. In addition, the ham radio stores the frequency on one VFO when you switch to the other. This provides an easy way to switch from one frequency to another and then quickly return to the original frequency. You can also switch one VFO to match the other by way of the VFO equalizing switch. Once you find the frequency you want, lock it in with the dial lock button. The rear panel of the rig offers a variety of connection options, including an external speaker jack, antenna connector, memory backup power socket, and accessory socket. The external speaker jack allows you to connect an 8 ohms speaker to the IC-720, although the rig does come with a built-in speaker. The antenna connector comes in handy when you need to connect a 50 ohms antenna using a PL-259 connector. The memory backup power socket allows you to hook up a 9~12V DC power supply for mobile use. You can also hook the 720a up to a car battery for installation in a vehicle. The accessory socket gives you access to various functions, such as frequency control, various outputs, and other helpful functions. Some useful accessories include an AM or CW/RTTY filter to help with noise reduction, a mobile mounting bracket for installation in a vehicle, and a desk microphone if installing the radio within a fixed position. Purchase an Icom IC-720a radio transceiver and start your journey into the world of amateur ham radio.
