#Ic 7300 rtty memories update#
Personal and firmware update data can also be stored on the card for easy setting. Memory card slot: The IC-7300 can store various content on an SD-card such as received and transmitted audio, voice memories, RTTY/CW memories, RTTY decode logs and captured screen images. These characteristics play an effective role in picking up very weak signals. This decreases noise components in the high and low frequencies of the filter passband and increases the Signal-to-Noise of the target signal. In SOFT selection the filter shoulders are roundly formed as in analog networks. The filter has an almost ideal shape factor, signals of the out of passband are extremely filtered out and it gives you better audio quality. IF filter shape: The SHARP selection emphasize the passband width of the filter. Either the transmit or receive audio can be displayed. To observe various 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. Waveform display area, vertical axis, is 80dB with reference level adjustment from -20dB to +20dB. The scope system adopt FFT with sweep speed max of 30 frames/second and A second touch of the screen changes the operating frequency and allows you to accurately tune. When you first touch the screen around the intended signal, the touched part is magnified. While listening to received audio, you can check the real-time scope and quickly move to an intended signal. Main features: Class leading real-time spectrum scope with high resolution, sweep speed and dynamic range. On transmitter side a built-in automatic antenna tuner memorizes its settingsīased on your frequency, so that it can rapidly tune when you change operating bands while the enforced tuning function allows a wide range of temporary antennas to be tuned. On receiver front-end the IC7300 has 15 discrete RF bandpass filters, high Q factorĬoils are used to minimize the loss and magnify the out-of-band rejection. The superior phase-noise values reduce noise components in both receive and transmit signals. The IC-7300 also improve the reciprocal mixing dynamic range and phase noise characteristics compared to the IC-7200. The new IP+ function improves 3° order intercept point performance, when a weak signal is received adjacent to strong interference the ADC device is optimized against signal distortion. making it possible to simplify the circuit construction. RF signals are directly converted to digital data and processed in the FPGA (Field-Programmable Gate Array, see below).
This ICOM employs an RF direct sampling system. The ICOM IC7300 is a multi-band transceiver with high performance and compact case.
