ICOM IC 7300 Base transceiver HF and 70 MHz

{

{ ICOM IC 7300 is the first apparatus with direct sampling in RF (direct conversion), this technical solution allows to reduce hardware complexity without however involving reduction of functionality.  {

{

There are in fact functions such as audio recording, RTTY decoding, IF output, control by USB port and a better signal / noise ratio compared to that of the IC-7200. {
{ Spectrum Scopes of high quality in real time {
005} {{} 002} a specterum Scopes "serious" is no longer a privilege of high -level systems. The high-resolution Spectrum Scopation of the IC-7300 works in real time with Waterfall function capable of providing high-level performance such as resolution, scan speed and dynamic range. {
Direct sampling system RF - a novelty in the radio -amoing field. {
instead of the traditional superhero circuit the IC-7300 uses a direct sampling system of the RF, an absolute novelty in the radio-amaemor field. {
This technology is found in SDR systems (Software Defined Radios) and in other radio devices. RF signals are processed through the FPGA (Field-Programmable Gate Array) circuit, making the physical elimination of the mixer and filters possible and offer high performance to the Spectrum Scopes in real time in a compact-size equipment. {
exceptional characteristics of the phase noise. {
{ exceeding the limitations of performance and costs of the superhero circuits the direct sampling of the RF tends to achieve ideal levels of phase noise. {
{ As the IC-7300, compared to the IC-7200, presents better noise characteristics of about 15 db (at 1 kHz of offset).
this exceptional value of phase noise reduces the noise components of both the received signal and the one transmitted. display lcd touch screen tft tft
the IC-7300 has a large TFT color LCD display with Touch screen function. This "user-friendly" interface allows intuitive operations. Using the Touch Screen software keyboard you can easily vary the various settings and edit the content of the memories. automatic incorporated antenna tuner
< Style = "Font-Family: Arial;"> the fast automatic antenna tuner is within-connection in a compact-dimensional apparatus: 240 (L) x 238 (p) x 95 (h). This makes the operations in portable simple and fun. audio quality "easy-ta-hear"
