![]() The audio scope function can be used to observe various AF characteristics such as microphone compressor level, filter width, notch filter width and keying waveform in the CW mode. The waterfall function 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. The combination of the waterfall function and the real-time spectrum scope assists in maximum receive performance of the IC-7300 and increases QSO opportunities without missing weak signals. A second touch of the scope screen changes the operating frequency and allows you to accurately tune. So, when you first touch the scope screen around the intended signal, the touched part is magnified. The IC-7300’s touch screen introduces a “Magnify” function. 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. You no longer have to choose whether to listen to the audio or have the spectrum scope sweep for signals as the IC-7300’s real-time spectrum scope offers the simultaneous operations found in higher tier models. In addition, the IC-7300 features the 70MHz band (European versions only), a large touch screen colour TFT LCD, convenient multi-function dial knob, automatic antenna tuner, voice recorder function and more. ![]() The new RF direct sampling system employed by the IC-7300 realises class leading RMDR (Reciprocal Mixing Dynamic Range) and Phase Noise characteristics. The combination of the real-time spectrum scope and waterfall function improves the quality and efficiency of HF operation. While listening to received audio, the operator can check the real-time spectrum scope and quickly move to the intended signal. The IC-7300’s real-time spectrum scope provides top-level performance in resolution, sweep speed and dynamic range. This new model has a high-performance real-time spectrum scope and employs a new RF direct sampling system. Photo to the right depicts specturm waterfall.The IC-7300 is a revolutionary compact radio that will excite HF operators from beginners to experts. Scope and the frequency is automatically selected as your operating frequency. Enhanced mouse operation for the spectrum scopeĬonnect a mouse to the USB port to change the operating frequency, tune the frequency, switch Fixed and Center mode, adjust the sweep speed and more. Maintaining your operating frequency on the Main band. This is useful when searching for multipliers on the Sub band while *2 Recognized level at the Spectrum WaterfallĪnother scope enhancement in the IC-7851 is the ability to simultaneously see” activity in both bands. *1 Number of dots shown at 60dB level, when receiving a signal Phase Noise excellence was –138dBc/Hz at 10kHz offset and –110dBc/Hz at 1kHz offset.)īy using the dedicated DSP for the Fast Fourier Transform (FFT) spectrum scope, the IC-7851 provides faster sweep speeds and better accuracy than other brand models, even the IC-7800. With the latest design of the LO, the IC-7851 will become the new benchmark for Phase Noise with –150dBc/Hz at 10kHz offset and –140dBc/Hz even at 1kHz offset. The LO's C/N ratio excels beyond ourĬompetitors, and the noise components generated in both receive and transmit signals are reduced virtually below detection. New local oscillator designīreaking tradition, Icom employs a Direct Digital Synthesizer (DDS) along with a Phase Locked Oscillator for the IC-7851’s Local Oscillator (LO). This enhancement enables the up-conversion design of the IC-7851 to have excellent filter performance while providing aĭynamic range that outperforms the competition in the 10kHz or less separation tests. ![]() Roofing filter, greatly improving the in-band adjacent signal performance. The IC-7851 utilizes a newly developed 1.2kHz
