ICOM IC-7300 HF/6M Direct Sampling Transceiver. New technology is changing the way receivers are being designed and the IC-7300 is an industry first as an RF, Direct Sampling System is being used in an entry level HF radio. The ability to digitize RF before various receiver stages reduces the inherent noise that is generated in the different IF stages of a radio. We feel the performance of the 7300 will far exceed your expectations for a radio considered entry level. RF direct sampling system. The IC-7300 employs an RF direct sampling system, where RF signals are directly convert to digital data. Then processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction as well as reduce noise that can mask weak signals. The new IP+ improves the 3rd order intercept point (IP3) performance improving the ability to copy a weak signal that is adjacent to either a strong interfering signal. In this process, A/D converter is optimized to reduce or eliminate signal distortion. RMDR and phase noise characteristics. The IC-7300s RMDR is about 97dB (typical value) improving the Phase Noise characteristics by about 15dB (at 1 kHz frequency separation). The superior Phase Noise characteristics reduce noise components for both receive and transmit signals. 15 discrete band-pass filters. The RF Direct Sampling is protected by an array of bandpass filters. The signal passes through one of the fifteen bandpass filters, where signals outside the passband are rejected. To reduce the insertion loss, the IC-7300 utilizes High Q factor coils. Large color touch screen. The large 4.3 color TFT touch LCD offers intuitive operation of functions, settings, and various operational visual aids such as the band scope, waterfall function, and audio scope. Like on the high-end rigs, the waterfall shows a change of signal strength over a period of time and allows you to find weak signals that may not be apparent on the spectrum scope. Use the audio scope function to observe various AF TX/RX characteristics such as microphone compressor level, filter width, notch filter width and keying waveform in the CW mode. Image below shows the Audio scope with the waterfall function and the oscilloscope. You no longer have to choose whether to listen to the audio or have the spectrum scope sweep for signals as the IC-7300s real-time spectrum scope offers the simultaneous operations found in some of the more expensive rigs! This means you can use either the spectrum scope or the waterfall to quickly move to an intended signal while listening to the receiver audio. The 7300s touch screen introduces a Magnify function. So, when you first touch the scope screen around the intended signal, the touched part is magnified. A second touch of the scope screen changes the operating frequency and allows you to accurately tune.
