Two independent DSP units (of the same type used in the IC-7800).
One DSP is dedicated to the transmitter and receiver, and the other to the spectrum scope.
HF/6m transmitter with a MOSFET PA delivering 200W output at full duty cycle.
Quiet, built-in switch-mode mains power supply.
Single HF receiver with I/Q second mixer, offering +40dBm 3rd-order intercept point*.
The single receiver should be seen not as a disadvantage, but as a plus. The single receiver allows no-compromise RX performance at a reasonable price; BNC sockets on the rear panel, and CI-V, allow easy connection and synchronization of a second Icom transceiver such as the 756Pro3 as a secondary receiver. Many prospective IC-7700 buyers already own an IC-756Pro3. Add the IC-7700 to your existing Pro3 for the perfect contest station; use the IC-7700 as your main transceiver, and the IC-756Pro3 as a spotting receiver.
Upgrade from your IC-765 or IC-775DSP, and get the benefits of a spectrum scope.
Built-in automatic tracking RF preselector.
The built-in tracking preselector, and relay-switched front end, offer unrivalled strong-signal HF performance.
Built-in high-speed automatic antenna tuner.
The tuner covers the HF and 6m bands.
Selectable 15, 6 and 3 kHz roofing filters.
As provided in the IC-7800.
Precision OCXO with ±0.05ppm frequency stability and 10 MHz Reference I/O jack.
The precision OCXO with 10 MHz REF I/O allows the IC-7700 to clock other equipment, or to be clocked from a higher-level master clock source.
7" color TFT LCD display.
The display includes a simulated analogue multi-function meter.
Rear-panel VGA socket for external video monitor.
Multi-function spectrum scope with adjustable resolution bandwidth (RBW).
The adjustable RBW permits spectral analysis of received signals. IMD products and spurs can be displayed.
Built-in RTTY/PSK31 modem requiring only a USB keyboard.
The built-in RTTY/PSK31 modem allows use of the IC-7700 as a complete digimode terminal, requiring only a keyboard. This is great for semi-portable operation (e.g. Field Day) or when shack space is at a premium.
IF-DSP notch filter with adjustable parameters.
The notch filter shape factor is selectable in 3 steps, and its maximum stopband attenuation is 70 dB.
Multi-function noise blanker implemented in DSP.
Separate, high-performance 6m receiver front end.
Digital voice recorder.
Front -panel USB ports for USB memory drive and keyboard.
The USB memory drive socket permits use of pocket USB memory drives. No CF card is required
