Adam, VA7. OJAB4. OJs IC 7. 56. Pro User Review. In July 2. 00. 0, I sold my IC 7. Pro from a local dealer. I am. delighted with the Pro. I find the Pro a big improvement over its predecessor, the 7. The Pro receiver seems much quieter than that of the 7. DDS. LO implementation. The DSP IF filters have much steeper skirts than the. QRM than. analogue filters. George, W5. YRs IF Filter. Page dramatically illustrates this point. Also, read. Georges Notes on roofing filters below. Hi all, I was an avid CB user from when my father bought his first SSB CB radio in the mid 70s. I had the pleasure of making many long distance contacts includ.

Upon returning home, I installed the Pro II in my station and began evaluating it. One week later, I can report that the verdict is very favourable. I have been using the Pro II, and have. Pro. So far, I have noticed superior strong signal handling, DSP IF filtering. DSP noise reduction NR. The adjustable noise blanker NB threshold is also a big. NB level in the old Pro. I find that by increasing the. NB threshold from 5. I can almost completely eliminate. HV power line noise. The improvement in on the. IC 7. 56. Pro II is dramatic.

By contrast, my neighbours transmissions overloaded the IC 7. Pro front end. so severely as to render the entire 2. The Manual Notch is at least as good as that of the Pro. The. Auto Notch is more effective in suppressing multiple tones, and the. DSP artifacts and munge. There was occasionally a. Pro. Note The. Auto Notch is not selectable in CW mode, as it would function to notch out the. CW signal that one is trying to receive. This applies to the IC 7. Pro and. IC 7. 56. Pro II. The Manual Notch can also be effective in removing the most disturbing. During a recent sked on 1. Matt KK5. DR, a band limited noise. Hz wide popped up on our frequency at about S9. Matts signal at that time was running. S6, and the interference obliterated it. By engaging MN and adjusting the Manual Notch control, I was able to pull Matts signal right. I defy any. analogue radio to emulate this. Using the Twin PBT with the 2. Hz CW filter selected, one can crank the CW. IF filter bandwidth down to 5. Hz as in the Pro. The CW Pitch control will not put the. CW signal out of the IF filter passband, even at 5. Hz bandwidth. December 2. Although my experience with my new Pro. PRO. has been greatly improved. I cannot recall ever having to use attenuation with. PRO although I normally used Preamp 1 most of the time. With the Pro. 2, I. Preamp or attenuator. The Pro. 2 front end is really that much. PRO. My experience with the original PRO dates back to. September 2. 00. 0. I can copy an S2 CW signal less than 1. Hz from an S93. 0 d. B signal using a. Hz filter setting. There is no evidence of desensing or cross modulation. I think that Icom has figured out how to make. Rohde Schwarz. I agree with comments  by other reviewers to the effect that a 2.

My experience with the strong local station at my QTH closely mirrors Adams. I can copy very weak signals almost within the same filter passband. S94. 0 d. B signal. When I tune out the main response to the strong signal. I can identify. This behavior is clearly superior to that of the PRO. I have a contest local station about a mile away who runs S96. B when he is on. Heard him on 4. CW the other evening and found that with no attenuation or other measures. I could copy weak signals within a few hundred Hz of his frequency. With the original PRO. Last night January 9, 2. I had an S96. 0 d. B AM signal on 7. I could copy an S3 SSB signal about 2 KHz away. I was getting a lot. AM signal, but it was not sufficient to desense or. SSB copy. This is the best test I have had of the Pro. November 2. 00. 3 It seems to me that Icom thoroughly assessed a wide range of operating environments. Telford Electronics Manuals.
