The IC 7800 has highly advanced DSP units to bring out the maximum DSP potential, Icom's engineering team has selected only the best parts to be used in the receiver stages, and have simplified the receiver circuit using the latest technology. As a result, the combination of digital and analog technology has achieved a level never seen before.

2 Roofing Filters:
The 1st IF filter commonly called the "Roofing Filter", covers the bandwidth required for operation of the transceiver's modes of operation. Typically transceivers will use only one filter for all the modes, including FM. While a 15 KHz or more filter is used in almost all current amateur transceivers, it is not the "optimal design" for SSB, CW or AM operation. The IC-7800 utilizes two 1st IF roofing filters, one for FM operation and the second with a 6 KHz bandwidth for SSB, CW, AM and data modes. This design combined with the wide dynamic range of the IF amplifier, dramatically improves the blocking characteristics for in band interference from strong signals.

AGC Loop management:
The engineering team at Icom redesigned the AGC loop management of the IC-756ProII. Combining the digital IF filter, manual notch and now the 1st IF stage, these are all controlled by the DSP unit. 110 dB of ultra wide dynamic range in the receiver, means the IF amplifier is distortion free from strong signals.

Double Conversion System:
While mixers often become a cause of signal distortion and spurious emissions, the IC-7800 utilizes a double conversion super-heterodyne system using a newly developed image mixer. This new mixer reduces signal distortion through IF processing and provides a high fidelity signal to the DSP unit.
