Continuing with this tradition, Icom announces the groundbreaking IC-7800!The IC-7800’s somewhat familiar looks will remind many HF operators of theIC-781. Starting with the first analog PLLCircuit in the IC-200 to the ground-breaking 32- bit DSP technology used in theIC-756PRO, Icom’s developed some of the most innovative radio equipment everMade. Digital Voice Recorder: Automatically capture incoming/outgoing calls onto an external memory card or flash drive.Icom is a pioneer in the amateur radio world. (A user operation PC is still required a base station PC is not.) Direct Remote Control Operation: Connect directly to an IP network using Icom’s optional RS-BA1 software and the IC-7800’s internal base station function.
The result is TWO identical receiversWith 110dB dynamic range, +40dBm 3rd order intercept point, and unmatched DSP technologyIn the HF bands something that has never been achieved in Ham radio! Simply put,Icom has developed the ultimate Amateur HF transceiver. The IC-7800 will be viewed as the pinnacleThe IC-7800 is an artistic fusion of over 40 years analog RF circuit developmentExpertise and cutting-edge digital technology. It takes amateurRadio to a whole new level of performance. They have not seen the IC-7800. Some of today’s operators still feel the IC-781 isThe pinnacle in amateur radio design.
You canSelect the filter widths from 15kHz, 6kHz and 3kHz, depending on operating mode.(FM mode is fixed to 15kHz.) Icom’s DIGI-SELThe pre-selector works between 1.5MHz and 30MHz and rejects distortion componentsDerived from out of band interference such as multimulti operation or strong broadcastStations. Before the 1st amplifier,The IC-7800’s three roofing filters block strong adjacent signals. The mechanicalRelay reduces secondary distortion at the primary stage of signal processing.Contesters know how frustrating it is to experience a strong adjacent signal that’sBlocking the receiver from pulling out a weaker signal. Internal distortion reductionThe IC-7800 uses durable mechanical relays for BPF switching instead of non-linearSemi-conductors, like switching diodes which can cause distortion. This allowed us to exploreNew technical dimensions. A first in Ham radio! To achieveThis superior receiver performance, Icom’s engineering team completely re-engineeredThe whole analog circuit and matched it to the DSP units.
This system provides wide dynamic range, reducing the distortionFrom strong signals and lower intermodulation.The IC-7800 has multiple AGC loops. The image rejection mixer for the 2nd stageReduces signal distortion through IF processing and provides a high-fidelity signalTo the DSP unit. The 1st mixer stage is driven with a signal from the high-driveLocal Oscillator with excellent C/N. The IC-7800 uses a double conversionSystem composed of a DMOS FET 1st mixer and a newly developed image rejection mixerFor the 2nd stage. The center frequency of the pre-selectorIs manually adjustable from the DIGI-SEL tuning knob on the front panel.Simple receiver system configuration is the best way to eliminate sources of theSpurious signals and distortion from transceivers.
Icom Ic-7800 Full PotentialFrom The
110dB of ultra wide dynamicRange in the receiver means the IF amplifier is distortion free from strong signals.The IC-7800 accommodates both the “on-the-fly” operator as well as theMost avid “tweaker” operator by providing tunable AGC preset and manualAGC level controls. Combining the digital IF filter, manual notch, and the1st IF stage, these are all controlled by the DSP unit. The other AGC loop detects the AGC voltage at the digitalIF filter output which has only passed the intended signal and draws the full potentialFrom the digital IF filter. The first AGC loop prevents saturation ofThe 1st IF amplifier.
The digital twin PBT allowsFlexibility of both the IF shift and narrowing of the digital IF passband by movingThe IF passband. This allows the operatorTo 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 crystalOnce the IF filters have been “tweaked”, the operator has additionalControl with the digital twin PassBand Tuning (PBT). Multiple filter memoriesStore the last used filter settings by using operation mode. This allows theOperator to adjust filter shaping (sharp or soft), filter bandwidth, and centerFrequency characteristics, without missing the action. ThenThe addition of the AGC VR control enables the user to “tweak” or fineThe IC-7800 incorporates the “build your own” filter.
Icom Ic-7800 Manual Notch Can
Rather than sharing circuitsUsed for HF, a separate preamplifier and mixer was designed especially for 6m. By suppressingThe noise components, an outstanding signal-to-noise ratio is achieved, providingClean, clear audio in all modes without distortion of the target signal.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.The IC-7800 was designed with the 6m aficionado in mind. Additionally, the filterShape of the Manual Notch can be adjusted in three steps, with more than 70dB ofThe 32-bit DSP processing power of the IC-7800 produces real results by separatingA signal component from the noise with the variable noise reduction. Making interference from RF sources suchAs beat signals and RTTY signals is a thing of the past. Signals such as heterodynes and AM Carriers can be eliminatedWith Automatic Notch filter technology. In addition to theFilter preset menu, the LCD indicates the twin PBT conditions across the top ofThe screen, so you can still use the lower portion of the TFT display for otherIn recent years, HF operators have marveled at how well DSP reduces interferingSignals and noise.
In addition to these features, the scope has3 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 andThe IC-7800 uses the OCXO (Oven Control Crystal Oscillator) unit which is stableTo within ☐.05ppm at 0☌ to 50☌. This is up to 500kHzOf spectrum! Also, there is a setting to allow for specific scope edges or centerThe span on the receiving frequency. While the scope rivals many of today’s commercial test sets,There are 7 steps, ranging from ☒.5 to ☒50kHz.
So Icom took a proven system, the IC-781, and used the basicFront panel design for the IC-7800, incorporating improvements for all the new featuresAnd controls.
