By sparing no expense throughout the signal chain, Icom has developed an amateur rig that challenges the performance of any "Military Grade" transceiver. You'll enjoy a +40dBm* 3rd order intercept point and ultra wide dynamic range that is, like its IC-7800 "big brother", amateur radio's highest. The IC-7700 continues Icom's setting of the bench mark for HF transceivers. Examples include the use of mechanical relays instead of non-linear semi-conductors and high performance DMOS mixers with a high-drive Local Oscillator. Using only two IF stages and Icom's image rejection technology, enables the IC-7700 to clearly reproduce very weak signals as well as very strong signals without distortion.
3kHz roofing filter
In addition to the 6kHz and 15kHz roofing filters, the IC-7700 has a 3kHz roofing filter before the 1st amplifier. It provides superior blocking dynamic range and allows you to pull out a weak signal while blocking strong adjacent signal.
Two 32-bit floating point units
Two independent DSP units (of the same type used in the IC-7800) are built-in: One for the transmitter and receiver; and one for the spectrum scope. The IC-7700 expands on the phenomenal performance of the 32-bit DSP that Icom introduced to the amateur world.
Automatic tracking pre-selector
As your first line of defense against interfering signals, the pre-selector rejects unwanted out of band interference from multi-multi operation or strong broadcast stations. The 7700's pre-selector automatically tracks the intended signal, keeping the pre-selector's bandwidth centered on the operating frequency.
200W output power at full duty
The push-pull power amplifiers using power MOS-FETs work on 48V DC. They provide a powerful 200W output power at full duty cycle and low transmit intermodulation. An effective cooling system maintains internal temperatures within a safe range and prevents thermal runaway.
Ultra high frequency stability
Your IC-7700 shares the IC-7800's standard stability of ?0.05ppm! Even on 6m band, that is less than 3Hz error from the Oven Controlled Crystal Oscillator! Also, a 10MHz reference frequency can be input/output for external equipment. 7-inch wide color TFT LCD
Contesting is often a marathon sport. Be kind to your eyes!
The large 7-inch wide (800?480 pixels) color display has to be seen to be believed! A high linearity needle S-meter, multi-function spectrum scope and RTTY/PSK31 messages are displayed in vivid color. In addition, the IC-7700 has a VGA connector allowing you to connect an external monitor.
Multi function spectrum scope
With the dedicated DSP unit, the spectrum scope offers linearity, accuracy and resolution. By adjusting the scope selectivity, the spectrum scope allows you to find those weak signals right next to strong ones! With this ground breaking scope, you can even monitor the distortion or width of the received signals. In addition, the scope range can be set independently from the receiving frequency. You can monitor the band condition between the selected sweep edges, as well as sweep a selected band width centered on the receiving frequency in the scope screen. RTTY /PSK31 operation without PC connection
The IC-7700 has a modulator and demodulator for the 2 major HF amateur digital modes. It is possible to encode and decode PSK31 as well as baudot RTTY signals by simply connecting a USB keyboard to the IC-7700. You no longer need to connect a PC for RTTY/PSK31 operation. In addition, transmitted and received messages can be stored to a USB memory device and transferred to your PC. $(function() {
