Icom IC-7700

Post by 2W0PWR on Wed Jan 23, 2008 11:20 pm



Icom UK Ltd is pleased to provide details of the forthcoming IC-7700 HF/50MHz transceiver. The IC-7700 shares many features with its “big brother”, the world famous IC-7800. With two independent DSP units, a +40dBm* 3rd order intercept point and ultra wide dynamic range to name but a few of these features, this transceiver is expected to a major success within the contesting community and the Amateur world as a whole.

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. With the 24-bit AD/DA converter, this com¬bination supports many DSP features in the IC-7700.

+40dBm ultra high intercept point
By sparing no expense throughout the signal chain, Icom has developed an amateur rig that challenges the perfor¬mance 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 me¬chanical relays instead of traditional semi-conductors and high performance DMOS mixers with a high-drive Local Oscillator. Using only two IF stages and Icom’s image rejec¬tion technology, enables the IC-7700 to clearly reproduce very weak signals as well as very strong signals without distortion.

Automatic tracking pre-selector
As your first line of defence 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 centred on the operating frequency.

200W output power at full duty
Newly designed push-pull MOS-FET amplifiers work with 48V DC; providing a powerful 200W of output power at full duty cycle with low IMD in all bands. A low-noise switching power supply is built-in

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 equip¬ment.

7-inch wide colour TFT LCD
Contesting is often a marathon sport. Be kind to your eyes! The large 7-inch wide (800×480 pixels) colour display has to be seen to be believed! A high linearity needle S-me¬ter, multi-function spectrum scope and RTTY/PSK31 mes¬sages are displayed in vivid colour. 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 (resolution band width), the spectrum scope al¬lows 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 condi¬tion between the selected sweep edges, as well as sweep a selected band width centred 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.

IF notch filter with adjustable notch filter characteristics
The IC-7700’s DSP controlled manual notch filter shape can be set in 3-steps for the various receiving conditions. Use a soft filter shape for tuning an interfered tone, then switch to the sharp one to cut 70dB off the tone.

Professional 6m receiver
While most HF/50MHz transceivers share the preamp be¬tween the HF bands and 50MHz band, the IC-7700 uses an exclusive preamp and mixer especially for 50MHz. This preamp and mixer are tuned to the 50MHz band and im¬prove cross modulation characteristics, particularly impor¬tant when picking up a very weak signal near a strong sta¬tion.

Digital Voice recorder
The Digital Voice Recorder (DVR) is a convenient function for contests, DXpeditions, field day and even normal op¬eration. Record your callsign, CQ, or other station informa¬tion into a memory. Independent “Rec” and “Play” buttons are on the front panel.

Digital Voice recorder
1 port for USB memory drive
1 port for USB keyboard
