Beginning with the 1st analog PLL circuit in the lC-200 to the ground-breaking 32- bit DSP technology used in the lC-756PRO, Icom's developed some of the most innovative radio stations equipment actually made. Carrying on with with this custom, Icom announces the ground-breaking IC-7800! The IC-7800's relatively familiar appearance will remind several HF providers of the lC-781. The IC-781 established benchmarks back again in the 1980'beds as that generation's greatest HF transceiver.

Free download torrent software. Some of today's workers still experience the IC-781 is usually the peak in beginner radio style. They have got not noticed the IC-7800. It will take amateur radio stations to a entire new level of overall performance. The IC-7800 will become seen as the peak stereo for years to arrive.

The IC-7800 will be an creative fusion of over 40 years analog RF routine development experience and cutting-edge digital technologies. The result is 2 similar receivers with 110dB dynamic variety, +40dBm 3rd order intercept point, and unmatched DSP technology in the HF groups something that has never happen to be achieved in Pig radio! Basically place, Icom has created the greatest Newbie HF transceiver.

No 1 else comes close up! +40dBm IP3 (3rd purchase Intercept Point) Icom's substantial analog RF circuit experience combined with cutting-edge electronic technology results in an astonishing 110dC receiver powerful variety and a +40dBm IP3 in the HF companies. A 1st in Pig radio stations! To attain this excellent receiver efficiency, Icom's executive team totally re-engineered the entire analog routine and coordinated it to the DSP units. This permitted us to explore new specialized proportions. Internal distortion decrease The IC-7800 uses durable mechanised relays for BPF changing rather of non-Iinear semi-conductors, Iike switching diodes which can trigger distortion. The mechanised relay reduces secondary distortion at the major stage of transmission processing.

Improved preventing Contesters know how annoying it can be to experience a strong adjacent transmission that'beds preventing the receiver from pulling out a weaker sign. Before the 1stestosterone levels amp, the IC-7800's i9000 three roof filters prevent strong surrounding signals. You can choose the filtration system widths from 15kHz, 6kHz and 3kHz, based on operating setting. (FM mode is fixed to 15kHz.) Icom's DIGI-SEL The pre-selector functions between 1.5MHz and 30MHz and rejects distortion elements produced from out of band interference such as multimulti operation or strong broadcast stations.

It instantly trails the designed signal keeping the pre-selector'h bandwidth structured on the operating regularity. The center frequency of the pre-selector is certainly manually adaptable from the DlGI-SEL tuning button on the front panel. Less internal phase noise Simple receiver program configuration is certainly the best way to eliminate resources of the spurious signals and distortion fróm transceivers. The lC-7800 utilizes a double conversion program composed of a DMOS FET 1scapital t mixer and a newly developed image rejection mixing machine for the 2nm phase. The 1scapital t mixer stage is driven with a sign from the high-drive Nearby Oscillator with great C/N. The image rejection mixer for the 2nd stage decreases signal distortion through IF refinement and offers a high-fidelity sign to the DSP unit.

This system provides broad dynamic range, decreasing the distortion from solid indicators and lower intermodulation. Multiple AGC loops The IC-7800 has multiple AGC loops.

Thé AGC voltages recognized in front side of and behind the digital IF filter in the DSP device. The 1st AGC cycle prevents saturation of the 1scapital t IF amp. The various other AGC cycle detects the AGC voItage at the digital IF filter output which provides only handed the intended transmission and draws the complete potential from the digital IF filtration system. Combining the electronic IF filtration system, manual level, and the 1scapital t IF stage, these are usually all controlled by the DSP device. 110dN of ultra broad dynamic range in the recipient indicates the IF amp is definitely distortion free from solid signals. Total AGC handles The IC-7800 accommodates both the “ón-the-fly” user as well as the most enthusiastic “tweaker” operator by providing tunable AGC preset and manual AGC degree handles. The AGC time constants can end up being fixed in the 3 presets (slow, medium and quick), adaptable from 0.1-6 sec.

At Feel) hold off. Then the add-on of the AGC VR handle enables the user to “tweak” or okay tune the AGC reaction period. Digital IF filtration system The IC-7800 incorporates the “construct your own” filter. This enables the operator to modify filter shaping (sharpened or soft), filter bandwidth, and center frequency features, without lacking the actions. Multiple filter memories store the last used filtration system configurations by making use of operation mode. This allows the operator to rapidly switch filter systems for constant operating situations, like as in a contest. Icom'h digital IF filter systems provide you efficiency that is usually not possible with crystal or mechanised filter systems.

Digital twin PBT (Pássband Tuning) Once thé IF filter systems have become “tweaked”, the owner has additional handle with the electronic california king PassBand Tuning (PBT). The electronic california king PBT enables versatility of both the IF change and narrowing of the digital IF passband by shifting the IF pássband. With the digital IF filters, PBT functionality allows you to reduce away all the disturbance and noise to listen to the real sign.

In inclusion to the filter preset menus, the LCD indicates the two PBT circumstances across the top of the screen, so you can nevertheless use the lower portion of the TFT screen for other radio functions. Digital regular notch filter In latest decades, HF employees possess marveled at how nicely DSP decreases interfering indicators and noise. Signals such as heterodynes and Are Carriers can be removed with Automatic Notch filtration system technology. Producing interference from RF resources like as beat signals and RTTY signals is usually a factor of the prior. Additionally, the filtration system form of the Manual Notch can become adjusted in three tips, with even more than 70dW of attenuation!

Adjustable level sound reduction The 32-bit DSP developing strength of the IC-7800 produces real outcomes by isolating a indication element from the sound with the adjustable noise reduction. By controlling the noise elements, an excellent signal-to-noise ratio is achieved, providing clear, clear sound in all settings without distortion of the target signal. Flexible sound blanker A newly designed, digital noise blanker considerably reduces pulse type sound. As part of the 32-bit DSP function, there are usually three adjustments: threshold degree, blank period parameter, and attenuation degree. 50MHz band preamplifier and mixér The IC-7800 was developed with the 6m enthusiast in thoughts. Instead than posting circuits used for HF, a independent preamplifier and mixer was designed specifically for 6m. This greatly increases the recipient sensitivity by decreasing intermodulation features, enabling weakened signal function without distortion or disturbance from solid indicators in the band.

Quad processing The IC-7800 includes four indie, 32- bit suspended DSP products and 24-bit AD/DA converters. By having four independent DSP models, the radio will respond to operator adjustments in an instant, as each DSP unit has a dedicated function. While there is definitely one for each recipient, this consists of the AGC and Filtration system handles, there is certainly a DSP unit for transmit mainly because nicely as a DSP unit for the Spectrum Scope. Two completely independent recipient circuits The IC-7800 includes two completely independent receivers, from thé antenna inputs aIl the way though to the stereo system headphone or personal external speaker outputs.

All the functionality of the very first receiver will be copied for a properly matched set of “Twins”. When linked to exterior stereo system headphone, major and sub receiver audio can be mixed or divided to right and still left. Real period spectrum scope With its introduction in the IC-781, having a spectrum range in an HF stereo changed the way HF workers “see” the band! Expected to the DSP device for the range, the IC-7800't spectrum range provides great sensitivity, with 80dW of dynamic variety.

While the scope rivals several of nowadays's commercial test models, there are 7 steps, varying from ±2.5 to ±250kHz. This is usually up to 500kHz of range! Furthermore, there is certainly a environment to enable for specific scope sides or middle the span on the receiving frequency. In add-on to these features, the scope has 3 amounts of attenuator (10dC, 20dW, 30dN), 3 forms of guide indicators (major receiver, subwoofer recipient, transmit), 3 ranges of sweep speed (gradual, mid, quick), peak keep and major/sub music group one contact change. Ultra higher balance OCXO unit The IC-7800 utilizes the OCXO (Range Control Crystal Oscillator) unit which is usually stable to within ±0.05pevening at 0°Chemical to 50°G. This specification indicates that even on the 50MHz music group, frequency error is much less than 2.5Hz .!

In inclusion, a 10MHz reference frequency can become input and output for accurate tuning. Central Handle In the high temperature of a big contest or a DX-pedition, control placement can be extremely important as every second counts. Therefore Icom required a proven program, the IC-781, and used the basic front panel design for the lC-7800, incorporating improvements for all the brand-new functions and settings. Often used functions, including RF energy and important speed have 3rd party large pulls for easy access. The “XFC” button is positioned effectively for keeping the switch by the remaining hand, and relocating the major switch with the right hand. 7-inches wide coIor TFT LCD WhiIe lcom's RF engineering téam reviewed receiver désigns for how thé IC-7800 hears a signal, close attention was also paid to how the operator sees a signal.

Details such as response time, color, quality, and visibility were extremely important. Thus, an energetic matrix 7-inch (800×480 pixel) TFT color display was selected for the IC-7800. This large display shows main, sub-band frequencies, like various settings, and working conditions, as nicely as the spectrum scope, S-meter, ánd RTTY/PSK31 decoded communications. The “virtual” S-meter displays soft and accurate analog-looking hook shifts whose reaction can be selectable from 3-measures (fast/mid/slow). In addition to the “virtual” meters, the IC-7800 provides electronic multi-function pub graphic metres to display various situations, including transmitter Pennsylvania temp and voltage.

If a larger display is usually preferred, the IC-7800 has a VGA connection for an external keep track of and an S-meter connection for an exterior analog S-méter. RTTY/PSK31 procedure without PC connection Another newbie radio very first can be the ability of getting and sending RTTY ánd PSK31 without the aid of a pc.

While décoded RTTY ánd PSK31 is shown on the 7-inch screen, simply connect a USB keyboard to the lC-7800 to send as properly. To decrease mistakes in getting RTTY, the IC-7800 offers a electronic twin maximum filtration system to reduce disturbance from various other signals in the band. In the PSK setting, the AFC function tracks the getting indication for precise tuning and the Internet function allows you to send at the shifted rate of recurrence. In addition, a overall 8 stations of RTTY ánd PSK31 transmit memory stores upward to 70 characters of often used communications for each station. 200W output energy at full duty routine The newly designed push-pull power amplifiers making use of power MOS-FETs work on 48V DC.

They supply a effective 200W output energy at full duty routine and low transmit intermodulation. An efficient cooling system maintains inner temperatures within a secure variety and prevents thermal runaway.
