* Optional UT-106 required depending on version.

160-6m full coverage internal automatic antenna tuner, and low current PA

The newly designed PA unit and antenna tuner, specifically designed for the IC-703, extends operating time by reducing the voltage and current consumption. The antenna tuner utilizes low current latching relays to cover 160-6m. While on a 9.6V DC source or less than 11V DC, many functions of the IC-703 are controlled by the microprocessor to extend the battery life.

While in low current mode, the IC-703 automatically switches to 5W output power (2W AM). While on 13.8V DC, the output switches to 10W (4W AM). Antenna tuner PA unit

Auto power scale meter

There's no need to calculate the output power, as the IC-703 automatically scales the power meter according to the output power of the rig. The full scale reading of the meter will indicate the power output setting of the rig. For example, if you are running at 5W mode, the full scale reading will be 5W. (Available power settings are 10/5/2.5/1/0.5W)

Low current mode

By using power efficient components for the PA, antenna tuner and the PLL circuits, the IC-703 is designed for maximum efficiency at 9.6V DC. When using the optional BP-228 battery pack, the IC-703 automatically switches into low current mode, thus allowing operation time of up to 7 hours*. While operating on high power, or 13.8V DC, the IC-703 can safely operate at a full 10W even if the power source drops to 11V DC.
* Tx:Rx:Stand-by =0.5:0.5:9 in SSB mode.

Stay on frequency, indoors or out

Whether safe indoors or exposed to the cold temperatures outdoors, the IC-703 will be right on frequency with the standard ±0.5ppm TCXO.

High sensitivity

The IC-703's receiver performance is in the same class as that of high end base stations: 0.16µV at 10dB S/N for 1.8 to 30MHz bands and 0.13µV for 50MHz at 10dB S/N (in SSB and CW modes).

Remote control head allows for easy operation while outdoors

Other keyer features include a variable CW pitch control (300.900Hz); operation with a bug; iambic paddles; or straight key. All these functions are available even when in low current mode.

Clean FSK, RTTY

Utilizing the TRUE RTTY mode, FSK, the IC-703 generates the tones internally for the cleanest possible signal on the band.

Also, whether operating FSK or AFSK data, you can tweak the IC-703 to be the perfect portable RTTY machine by adding the optional FL-52A filter.

455kHz IF filter selections

The 455kHz IF allows you to upgrade the standard 455kHz filter, FL-65, to improve your selectivity by installing an optional filter into the filter slot.

Built-in SWR analyzer

Digital IF filter, manual notch filter, digital twin PBT and more. The latest digital features are incorporated in this compact radio from two DSP chips that deliver superior processing performance. Of course, those features work on all ham bands, from HF to the 70cm band.

AGC loop performance controlled by DSP

You will never experience AGC pumping from a signal filtered out by the DSP system. The digital IF filter and manual notch filter are inside the AGC loop, so you will not encounter AGC blocking. The AGC time constants are flexibly adjustable from slow, middle, fast (or AGC-off) for each operating mode.

Digital IF filters

All the filters you want at your fingertips! You will never have to purchase "Optional" filters as the IC-7000 has adjustable digital filters. You just dial in the width you want and select whether you want a sharp or soft filter shape for SSB and CW modes. Then to pull-in the the weak ones, with a quick turn of the concentric twin PBT knobs, you can either narrow the IF passband, or shift the entire passband to eliminate the QRM.

2-point MNF (Manual notch filter)

Pull out the weak signals in crowded band conditions with Icom's NEW two-point MNF (manual notch filter). Apply 70 dB of rejection to two signals at once! Notch width is adjustable-wide, medium, and narrow - and an auto-tuning notch filter is available, too.

Digital noise reduction

Noise reduction reduces background noise and improves signal-to-noise ratio. The noise reduction level is adjustable in 16 steps. It improves the readability of voice and data signals.

Digital noise blanker

2.5 inch color TFT display

The 2.5 inch color TFT display presents numbers and indicators in bright, concentrated colors for easy recognition. You can choose from 3 background colors and 2 font styles to suit your preference, in addition to a large operating frequency readout. And more, the Video output jack on the rear panel allows you to view a magnified display on an external monitor*.
* 3.5(d) mm monaural cable is required for connection.

SSB transmit bandwidth adjustable

The SSB transmit bandwidth is selectable from 100, 200, 300, 500Hz at the high-pass edge, and 2500, 2700, 2800, 2900Hz at the low-pass edge respectively. 3 types of high and low combinations can be set in the quick set mode.

 

2-mode band scope

The band scope function lets you watch conditions around the band and visually assists in finding other stations. In center mode the band scope range is centered on the receiving frequency (±10kHz to ±250kHz). In Fixed mode the band scope sweeps a fixed range.

Multi function meter and SWR graphic display

The IC-7000 displays power level, SWR, ALC and compression level of the speech compressor. The SWR graphic display is useful for tuning antennas. The measuring step is selectable from 10/50/100/500kHz steps and the number of measuring steps is adjustable from 3 to 13 steps.

IC-7200

HF/50MHz Transceiver

features

IF DSP

The latest IF DSP technology is employed in the IC-7200. While the IC-7200 is an entry-class transceiver, advanced digital features are comparable to higher class transceivers.

AGC loop management

Distortion and blocking from strong nearby signals are prevented by placing DSP functions inside the AGC loop. The AGC time constants are selectable from fast, slow and off for each operating mode.

Digital IF filter

Optional filters will never be required for the IC-7200. The built-in digital filter allows you to flexibly select the filter width and shape from soft and sharp* and provides cutting-edge filter characteristics.
*Filter shape is selectable for SSB and CW modes only.

Manual notch filter

IC-7800

HF/50MHz Transceiver

features

Icom is a pioneer in the amateur radio world. Starting with the first analog PLL circuit in the IC-200 to the ground-breaking 32- bit DSP technology used in the IC-756PRO, Icom’s developed some of the most innovative radio equipment ever made. Continuing with this tradition, Icom announces the groundbreaking IC-7800!

The IC-7800’s somewhat familiar looks will remind many HF operators of the IC-781. The IC-781 set benchmarks back in the 1980’s as that generation’s ultimate HF transceiver. Some of today’s operators still feel the IC-781 is the pinnacle in amateur radio design. They have not seen the IC-7800. It takes amateur radio to a whole new level of performance. The IC-7800 will be viewed as the pinnacle radio for years to come.

The IC-7800 is an artistic fusion of over 40 years analog RF circuit development expertise and cutting-edge digital technology. The result is TWO identical receivers with 110dB dynamic range, +40dBm 3rd order intercept point, and unmatched DSP technology in the HF bands something that has never been achieved in Ham radio! Simply put, Icom has developed the ultimate Amateur HF transceiver. No one else comes close!

+40dBm IP3

(3rd order Intercept Point) Icom’s considerable analog RF circuit experience combined with cutting-edge digital technology results in an astonishing 110dB receiver dynamic range and a +40dBm IP3 in the HF bands. A first in Ham radio! To achieve this superior receiver performance, Icom’s engineering team completely re-engineered the whole analog circuit and matched it to the DSP units. This allowed us to explore new technical dimensions.

Internal distortion reduction

The IC-7800 uses durable mechanical relays for BPF switching instead of non-linear semi-conductors, like switching diodes which can cause distortion. The mechanical relay reduces secondary distortion at the primary stage of signal processing.

Improved blocking

Contesters know how frustrating it is to experience a strong adjacent signal that’s blocking the receiver from pulling out a weaker signal. Before the 1st amplifier, the IC-7800’s three roofing filters block strong adjacent signals. You can select the filter widths from 15kHz, 6kHz and 3kHz, depending on operating mode.
(FM mode is fixed to 15kHz.)

Icom’s DIGI-SEL

The pre-selector works between 1.5MHz and 30MHz and rejects distortion components derived from out of band interference such as multimulti operation or strong broadcast stations. It automatically tracks the intended signal keeping the pre-selector’s bandwidth centered on the operating frequency. The center frequency of the pre-selector is manually adjustable from the DIGI-SEL tuning knob on the front panel.

Less internal phase noise

Simple receiver system configuration is the best way to eliminate sources of the spurious signals and distortion from transceivers. The IC-7800 uses a double conversion system composed of a DMOS FET 1st mixer and a newly developed image rejection mixer for the 2nd stage. The 1st mixer stage is driven with a signal from the high-drive Local Oscillator with excellent C/N. The image rejection mixer for the 2nd stage reduces signal distortion through IF processing and provides a high-fidelity signal to the DSP unit. This system provides wide dynamic range, reducing the distortion from strong signals and lower intermodulation.

Multiple AGC loops

The IC-7800 has multiple AGC loops. The AGC voltages detected in front of and behind the digital IF filter in the DSP unit. The first AGC loop prevents saturation of the 1st IF amplifier. The other AGC loop detects the AGC voltage at the digital IF filter output which has only passed the intended signal and draws the full potential from the digital IF filter. Combining the digital IF filter, manual notch, and the 1st IF stage, these are all controlled by the DSP unit. 110dB of ultra wide dynamic range in the receiver means the IF amplifier is distortion free from strong signals.

Full AGC controls

The IC-7800 accommodates both the “on-the-fly” operator as well as the most avid “tweaker” operator by providing tunable AGC preset and manual AGC level controls. The AGC time constants can be set in the 3 presets (slow, medium and fast), adjustable from 0.1–6 sec. (0.3–8 sec. at AM) delay. Then the addition of the AGC VR control enables the user to “tweak” or fine tune the AGC reaction time.

Digital IF filter

The IC-7800 incorporates the “build your own” filter. This allows the operator to adjust filter shaping (sharp or soft), filter bandwidth, and center frequency characteristics, without missing the action. Multiple filter memories store the last used filter settings by using operation mode. This allows the operator to quickly switch filters for constant operating conditions, such as in a contest. Icom’s digital IF filters give you performance that is not possible with crystal or mechanical filters.

Digital twin PBT (Passband Tuning)

Once the IF filters have been “tweaked”, the operator has additional control with the digital twin PassBand Tuning (PBT). The digital twin PBT allows flexibility of both the IF shift and narrowing of the digital IF passband by moving the IF passband. With the digital IF filters, PBT performance allows you to cut away all the interference and noise to hear the actual signal. In addition to the filter preset menu, the LCD indicates the twin PBT conditions across the top of the screen, so you can still use the lower portion of the TFT display for other radio operations.

Digital manual notch filter

In recent years, HF operators have marveled at how well DSP reduces interfering signals and noise. Signals such as heterodynes and AM Carriers can be eliminated with Automatic Notch filter technology. Making interference from RF sources such as beat signals and RTTY signals is a thing of the past. Additionally, the filter shape of the Manual Notch can be adjusted in three steps, with more than 70dB of attenuation!

Variable level noise reduction

The 32-bit DSP processing power of the IC-7800 produces real results by separating a signal component from the noise with the variable noise reduction. By suppressing the noise components, an outstanding signal-to-noise ratio is achieved, providing clean, clear audio in all modes without distortion of the target signal.

Adjustable noise blanker

A newly designed, digital noise blanker significantly reduces pulse type noise. As part of the 32-bit DSP function, there are three adjustments: threshold level, blank time parameter, and attenuation level.

50MHz band preamplifier and mixer

The IC-7800 was designed with the 6m aficionado in mind. Rather than sharing circuits used for HF, a separate preamplifier and mixer was designed especially for 6m. This greatly improves the receiver sensitivity by reducing intermodulation characteristics, enabling weak signal work without distortion or interference from strong signals in the band.

Quad processing

The IC-7800 incorporates four independent, 32- bit floating DSP units and 24-bit AD/DA converters. By having four independent DSP units, the radio will respond to operator changes in an instant, as each DSP unit has a dedicated function. While there is one for each receiver, this includes the AGC and Filter controls, there is a DSP unit for transmit as well as a DSP unit for the Spectrum Scope.

Two completely independent receiver circuits

The IC-7800 incorporates two completely independent receivers, from the antenna inputs all the way though to the stereo headphone or individual external speaker outputs. All the performance of the first receiver is duplicated for a perfectly matched set of “Twins”. When connected to external stereo headphone, main and sub receiver audio can be mixed or separated to right and left.

Real time spectrum scope

With its introduction in the IC-781, having a spectrum scope in an HF radio changed the way HF operators “see” the band! Due to the DSP unit for the scope, the IC-7800’s spectrum scope provides excellent sensitivity, with 80dB of dynamic range. While the scope rivals many of today’s commercial test sets, there are 7 steps, ranging from ±2.5 to ±250kHz. This is up to 500kHz of spectrum! Also, there is a setting to allow for specific scope edges or center the span on the receiving frequency. In addition to these features, the scope has 3 levels of attenuator (10dB, 20dB, 30dB), 3 types of reference markers (main receiver, sub receiver, transmit), 3 levels of sweep speed (slow, mid, fast), peak hold and main/sub band one touch switch.

Ultra high stability OCXO unit

The IC-7800 uses the OCXO (Oven Control Crystal Oscillator) unit which is stable to within ±0.05ppm at 0°C to 50°C. This specification means that even on the 50MHz band, frequency error is less than 2.5Hz! In addition, a 10MHz reference frequency can be input and output for accurate tuning.

Central Control

In the heat of a big contest or a DX-pedition, control placement is extremely important as every second counts. So Icom took a proven system, the IC-781, and used the basic front panel design for the IC-7800, incorporating improvements for all the new features and controls. Often used functions, including RF power and key speed have independent large knobs for easy access. The “XFC” button is placed efficiently for holding the button by the left hand, and moving the main dial with the right hand.

7-inch wide color TFT LCD

While Icom’s RF engineering team reviewed receiver designs for how the IC-7800 hears a signal, close attention was also paid to how the operator sees a signal. Details such as response time, color, resolution, and visibility were extremely important. Thus, an active matrix 7-inch (800×480 pixel) TFT color display was selected for the IC-7800. This large display shows main, sub-band frequencies, including various settings, and operating conditions, as well as the spectrum scope, S-meter, and RTTY/PSK31 decoded messages. The “virtual” S-meter shows smooth and accurate analog-looking needle swings whose response is selectable from 3-steps (fast/mid/slow). In addition to the “virtual” meters, the IC-7800 has digital multi-function bar graphic meters to show various conditions, including transmitter PA temperature and voltage. If a larger display is desired, the IC-7800 has a VGA connector for an external monitor and an S-meter connector for an external analog S-meter.

RTTY/PSK31 operation without

PC connection Another amateur radio first is the capability of receiving and transmitting RTTY and PSK31 without the aid of a computer. While decoded RTTY and PSK31 is shown on the 7-inch display, simply connect a USB keyboard to the IC-7800 to send as well. To reduce errors in receiving RTTY, the IC-7800 has a digital twin peak filter to reduce interference from other signals in the band. In the PSK mode, the AFC function tracks the receiving signal for accurate tuning and the NET function allows you to send at the shifted frequency. In addition, a total 8 channels of RTTY and PSK31 transmit memory stores up to 70 characters of often used messages for each channel.

200W output power at full duty cycle

The newly designed 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.

Microphone equalizer

One of the four 32-Bit DSP units is used for adjusting the transmit audio. Digitally tweak your transmit audio with the separate bass and treble controls for incredible sounding audio. This built-in audio equalizer has a total of 121 combinations for each phone mode, so you can master the warm, full audio you want. In addition to the equalizer, a new parametric transmit bandwidth for the SSB mode allows the operator to set both the high- and low-pass filter limits. (100, 200, 300, 500 for the high-pass and 2.5, 2.7, 2.8 and 2.9 kHz for the low-pass). Then store the filter settings into the three bandwidth memories. The operator may now go from DX to rag chew audio with the push of a button.

RF speech compressor

The IC-7800 utilizes the 32-bit DSP for the RF speech compressor providing the maximum punch without the fuzzy sound. It’s great for breaking through the noise and hash to complete the QSO.

CF memory card

Making big scores means keeping your team fresh on those long DX-peditions or Multi Op contests. Swapping out operators usually involves time-wasting radio tweaks, because each operator has their own favorite settings to best match their operating style. This all changes with the CF memory card! Prior to a contest, operators may record their preferred IC-7800 settings such as filter, Digital Voice Recorder (DVR) memories, antenna settings, etc. When it’s their turn to operate, simply insert their CF card into the IC-7800. In a flash, the ‘7800 is now “their rig”, and there’s nearly zero down time!

Digital voice recorder

The IC-7800’s Digital Voice Recorder (DVR) is a very convenient function for contests, DX-peditions, and even normal operation. Record your callsign, CQ, or contest number in up to four memory locations. A total of 90 seconds is available for the four memories, with each memory channel being soft partitioned to allow custom recording sizes. The front panel control of the DVR allows you to record incoming signals up to 200 seconds for 20 channels (Max. 30 sec. per channel). The playback automatically mutes the receiver for clear playback of the previous 15 seconds of recorded audio. It’s the perfect feature for those contest operators wanting to improve their UBN reports.

Digital IF data filter

For the AFSK operators, the IC-7800 automatically adjusts its digital IF filters for optimum settings. When the digital IF filters are adjusted to 500Hz or less in SSB or SSB-D, the sharp CW bandpass filter (BPF) is selected and the 1/4 tuning step is selected.

4 antenna connectors

For the ultimate in antenna control, the IC-7800 has 4 antenna connectors with a programmable automatic antenna selector. Each antenna connector can be customized to the antenna usage type, such as a beam for TX and a beverage antenna for RX, as well as to specific antenna/band configurations.

Complete CW features

All of the following CW capabilities are included in the IC-7800:

• DSP controlled CW keying waveform shaping
• Multi-function electronic keyer with adjustable keying speed from 6–60 wpm, dot-dash ratio from 1:1:2.8 to 1:1:4.5 and paddle polarity
