the icom 7800 is clearly one the most advanced amateur radio ever developed. it utilizes four separate 32-bit floating point dsp chips, has a 7-inch wide tft display, built in rtty/psk31 receive and transmit plus compact flash technology. as impressive as the features are; it is performance that sets this radio apart. by sparing no expense an incredible +40dbm intercept point has been achieved with ultra wide dynamic range. and you enjoy this incredible performance in two fully independent receiver circuits controlled on the left side of the radio. there is even a separate preamp and mixer for the 6 meter band. the rear panel features four primary antenna inputs [so-239] plus provisions for receive antenna a and b. and nothing is sacrificed on the transmit side. the newly designed push-pull mosfet amplifiers work with a 48 vdc, providing a powerful 200 watts of output at full duty cycle with low imd in all bands. a 120 vac switching power supply is built-in. the supplied accessories include: rack mounting ears, compact flash [64 mb] and various plugs (mic not supplied).
this new radio covers the hf ham bands plus 6 meters (receive from 30 khz - 60 mhz). the high resolution 7 inch tft color lcd display provides more operating information than you've ever had before, including a spectrum scope. and icom really stands behind this radio with a limited two year factory warranty.
important upgrade note: icom has produced an important upgrade for the ic-7800. they have added a 3 khz roofing filter. this upgraded model is what universal radio is currently shipping. ver. 2.0 will be displayed at the lower right corner of the display when the radio is first switched on during the boot up sequence if it has the 3khz roofing upgrade.
icom 7800是迄今为止最顶级的业余无线电台.他配备了四路独立的32位波动点dsp芯片,拥有7英寸宽的tft显示屏,包含了rtty/psk31两种数据收发模式以及cf卡储存技术(以便多用户使用配置).他那令人印象深刻的特点那样,他的表现将这台电台分离开来.他毫无保留的将一种难以置信的+40dbm的截点应用于极宽的动态范围.而你将会被他左侧那拥有难以置信表现的完全独立的双回路接受所深深吸引.在6米波,他甚至有独立的前置放大器混合器.后面板布局主要有四个主天线输入和两个用于接收的备用天线座a和b.新型推挽式晶体管功放由48v供电,是他具备了全波段上200w强劲的功率.120v的开关电源是内置的.
