Out of production ICOM IC 7600 50 Mhz TRANSCEIVER HF BASE

Firmware Update


This new model is a great leap forward from the previous IC-756 PRO III as it takes advantage of the circuits and technologies involved in IC-7800. Double conversion configuration, dual DSP unit and 3 kHz filter is used in the first conversion makes it very similar to that obtained with receiving the IC-7800/7700. Add also the large screen and high resolution on which you can observe the various information and presentation broadband signals overview as well as the outlet for the USB stick can be connected to the keyboard or a large capacity external static memory making it very flexible system management with digital emissions and its ability to retain the recording of all activity. We can summarize by saying that the model 7600 is the Supreme than you could wish for in features and performance of a device for the HF.

  • 104 dB of dynamic with + 34 dBm third order intercept point is across the spectrum of HF.
  • Double conversion Circuit with actual improvement of IMD.
  • Two units 32-bit floating point DSP, one used in the transceiver and the other dedicated to the presentation Overview.
  • Three filters selectable in the first conversion: 3 kHz, 6 kHz, 15 kHz.
  • Screen Very wide TFT (15 cm) with high resolution
  • Connection USB key and keyboard to issue PSK31 and RTTY etc.
  • Demodulator and encoder for PSK and RTTY Office with which you delete using a PC additional (essential configuration that has been forced so far).
Double DSP
The first used to transmit/receive circuits; the second for management dedicated to the sole presentation Overview. The IC-7600 32-bit DSP is run by two floating point unit which makes the device very similar to models in IC-7800 and IC-7700. Combined with our features analog technologies gained from decades of experience improves its performance especially in high-speed signal processing.
The three first conversion filters
The unit has three first conversion filters upstream of the first stage of medium frequency. The operator can then as necessary select the most compatible to crowding in range between 3. 6 and 15 kHz (the latter only suitable for FM). With the value of 3 kHz you can select the required signal without unnecessarily burdening the stadium below.
Noise reduction
Spectacular results can be obtained with the 32-bit DSP processor with which you can effectively separate the noise components with 16 shades variables. The result is an excellent signal-to-noise ratio by obtaining a clear and clean in all operating modes without any distortion on the required signal.
The Noise blanker
Noise suppressor suppresses effectively all impulsive source signals such as those generated by the candles of internal combustion engines. Setting obtainable extends for 100 shades.
Medium frequency digital filter
With that filter the operator can optimize the characteristics as necessary when selecting between ' soft ' and ' sharp '. For this application there are several memoirs that will adjust the characteristics of the last filter modeled concurrently operating mode used. With this possibility and especially in contest where time is short, the operator can easily make the selection depending on the conditions present in the range.

style = "margin: 0px; padding: 0px; color: rgb (0, 0, 0); font-family: "Lucida Sans Unicode" and "Lucida Grande", sans-serif; font-size: 11px; line-height: 17.05 px; background-color: rgb (255, 255, 255); " >Intermodulation strongly diminished by the band double conversion configuration
As can be seen from the curves attached circuit diagrams of IC-7800 and IC-7700 takes a double conversion configuration which leads to a considerable value for the second image rejection mixer with double conversion solution is technically more difficult to achieve a stable operation of the mixer, however, greatly reduces the distortion on the medium frequency signal and its processing with the result of getting a good signal fidelity at the entrance of the DSP unit. Therefore the IC-7600 will give a clearer signal and different from the usual.

The management of AGC loop controlled by DSP unit
The signal necessary for AGC is picked up after the medium frequency digital filter. This will prevent the eventual capture of the AGC due to strong adjacent signals. Should be understood that both the digital filter of the media that the notch filter (i.e. attenuation peak) are also processed in the ' loop ' of the AGC.

Digital dual PBT
When you have adjusted the best ' digital filters, the operator may use double again ' Band
Pass Tuning '. With the PBT as known IF flexibility is greatly improved by moving me-Shift '
the IF Shift then orrimizzando digital filter IF selectivity in that its bandwidth is moved (in frequency). Using the digital filter in IF, through the performance of PBT can suppress interference and noise around the required signal.

The digital filter ' Notch ' manual (or attenuation peak)
Beat products as that characteristic will be deleted carriers effectively relying on automatic notch filter with that you can effectively eliminate annoying beatings especially receiving RTTY. Note that you can change filter characteristics-as shown-reaching optimum-till 70 dB-interfering signal.
Large TFT screen
The screen of the IC-7600 is distinguished by its large size, excellent reproduction in various gradations of colour and high contrast with any incidence is observed. The requirements are thus greatly improved readability regardless of installation carried out. Also notice that the response time is constant in the reproduction of various colors from which there is a natural movement of the various ' parayilbasheer ' in the overview. Back lighting also ensures reduced startup time, stabilizzataed brightness a longer service life.
The ' Watch '
With this function you can receive simultaneously two signals on the same band. The receiver (Main) and the secondary (Sub) can be easily switched as they both have the same components.
High-stability TCXO
The intrinsic stability of the IC-7600 equals ± 0.5 ppm because it employed a high-stability crystal oscillator and temperature (from 0 to +50° C). That stability remains constant even in ways that critics such as PSK 31 or RTTY.
Presentation overview
A dedicated DSP helps in presentation Manager overview aumentandonela dynamic range, scope, response time, and the accuracy of the frequency that you specified. This presentation uses the medium frequency digital filter that is built into the DSP unit. The resolution for optimal bandwidth is selected automatically depending on the excursion of the ' sweep '. Note that the range can be independently set regardless of the incoming frequency at the time. It follows that you can
monitor conditions in band between the limits selected for the sweep (max. 500 kHz), this for

how ' fixed ' as well as ' central ' mode where in centre of screen you have the currently selected frequency.
Logging of received signal
Much in DX signals that may be useful to contest the registration of received signal in a large static memory. The IC-7600 has two buttons located on the front panel ' REC ' and ' PLAY ' with whom you have immediate access to the recorder. Interestingly, by pressing the ' Play ' button the recording begins with 15 seconds to spare so assuming that a name is not immediately clear or intelligible you can listen with comfortable without making him repeat the corresponding. There will also be 4 channels to transmit (with a capacity of 90 seconds per channel) as well as 20 channels for receiving (with the capacity of 30 s per channel). In addition to those
the recording capacity of the signal received can be saved in the ' key ' through the appropriate USB socket

The use of RTTY and PSK
Finally no longer using the PC associated, just enter the keyboard in USB socket and you are ready to communicate with these two wonderful ways of issue. It was expected the use of ' Twin Peak filter (filter that's Pike the two sgnali Mark and Space as long as they have the diversion of 170 Hz) as well as an indicator for the correct tuning. There are 8 memories each of 62 characters per station and streamline data egistravi thus the QSO.
Audible beyond the amateur radio band.
These limits can be programmed not only for the slice of spectrum used internationally but also because of the subbands as those used for the contest, modes etc. So if you try to operate outside of the gang used as you will get a warning signal will sound and the display OFF.
Stacked three-band operations
Is a convenient feature for those who often change your bandwidth and operating mode. It records the operating frequencies and modes used in three channels for each band therefore as soon as you invoke another band the unit will power up the last frequency and mode used on the latter. Very useful function in the contest.
Dynamic compressor
Pure digital dynamic compressor increases the envelope with the broadcast aumentandotanto the average level of the transmitted signal that his understanding.
Multifunction tool
Allows the operator to easily and accurately realize the main operating conditions. In addition to the level of the received signal, the signal is issued, the level of compression of the ALC and the indication of the instrument indicates the current consumption and ROS the voltage feeding the PA and its temperature.
USB ports on front and back
The device has two USB ports positioned front and back. You can then connect the keyboard to the front panel and the rear panel PC or otherwise. Via PC will pilot the apparatus making use of ' date format ' CI-V.
Features for graphic artists
The apparatus employs 4 memories each capable of 70 characters to register the data applicants relating to operator and its station. For the transmission of recorded data may be used as well by the keyboard (Function button) connected to the USB connector.
Microphone EQ and adjustable bandwidth transmission
Internal audio equalizer features separate bass and treble settings with the
possibility of combinations so you can perfectly adapt the 121 type of operator's voice into the microphone used. The transmitted bandwidth is selectable between 100, 200, 300, 500 Hz (low limit) and 2500, 2800.2900 Hz (high limit). Estimated optimum combinations which can be recorded. With such flexibility for shaping of the waveform made from DSP you will get a quality for audio broadcast adjusted depending on your preference of the operator and best decided by the correspondent.
The power amplifier (PA)
PA uses FETs RD100HHF1 with which you get excellent quality sulsegnale broadcast with low IMD characteristics. The large heatsink fan with an effective emission temperature even during long periods contains easily achieved with RTTY emissions during contests and the like.
Two settings for relay T/R

T/R switching can be done through a conventional mechanical relays (max 16V/0.5 A) or by a FET (max 250V/200 mA). Using FET switching suits in combination with linear unbranded valves of Icom on which the potential difference for their switching is obvious. With CW plus the rise time for the envelope of the signal is selectable 10 ms.

Internal antenna tuner
A fast tuner records the parameters used for each band and its antenna used, so returning to the frequencies had previously required parameters will be invoked without ricorrerer to a new agreement. Optimized for high voltage capacitors.
