It had little or no effect on noise for which this function was designed to remove or decrease. Noise Blanker (NB) First of all, I got to say that I found this function to be mostly "useless", not able to blank noise of any type. If I were to place a single word here to describe it, I would say "EXQUISITE!". ICOM, has raised the bar, on the level of design, and construction of HAM equipment. It’s highly reliable, and very efficient, generating minimal amounts of heat. The construction is of a type that I have seen only in NASA space launch equipment. They are very very high quality construction, and the soldering is of the highest quality also. The circuit boards are nearly 100% SMT, or Surface Mount Technology. Besides the metal shielding provided by outer covers, there is a shield plate on the inside of the top and bottom too. Nearly the entire chassis is a integrated heatsink. The chassis is 1/8 inch thick cast aluminum, with cast partions between the various compartments. It’s a pretty standard layout, and functions. The key pad is a little "tight", for those if us with big American fingers. A variable refresh rate on the sweep would have been a nice feature too. The vertical gain & sweep should have been calibrated with S-meter readings, but it ’ s not, this would have been even more useful.
The lowest span, could have been lower, to allow for a more critical analyzation of signals. The Spectrum Scope, is highly useful, and has a wide enough span, to see if a band is active at a quick look. A feature I liked right away, is the fact that you can see in one look, all the frequency info you need, VFO, memories, sub recv. It ’ s about time the modern manufacturers got back to it. KEYER plug on the front of a rig ! WOW!, but it ’ s not a new concept, that ’ s the way rigs were back from the beginning of amateur radio up till about the 50-60 ’ s. It’s a standard feature on almost all late model rigs. "fuzzy logic", meaning that the tuning of the VFO knob, increases or decreases the tuning rate with the speed of the spin, applied to it. The tuning rate is also controlled by what is no w widely know and used as The back lighting of the meter and LED indicators, are adjustable via a menu setting. The meter, is very good, and has good accuracy. But, generally the 756 ’ s is good, and has a easy to adjust, front panel " drag " setting. The VFO knob has a good " feel " to it, personally I like a little more weighted " flywheel " effect on a VFO knob. Most are self explanatory, and common to all ham rigs now days. I won ’ t go into great detail about the front controls, like the " BIG Magazine reviewers ". Imagine if a 781 & a 775 mated, the 756 is the likely offspring. With allot of influence from it ’ s big brother the IC-775. If you have seen pictures of an IC-781, or seen one in person, you ’ ll see where the inspiration for the front end of the 756 was born, it ’ s very similar, A smaller version of the BIG 781. A nice set of " grippy " rubber feet would really help keep this rig in place when I plug in or out the headphones, or paddle keyer. This unit did NOT have any rubber on the feet, so, the rig will slip easily on a smooth table top. It has a " drop lip ", in the front, and flip down legs to tilt the rig up at and angle. The bottom side is also the same finish as the top side. The entire back end of the unit is a large heat sink of bare cast aluminum. Very few protrusions are found on the rear of the rig. It appears to be a " powder coat ", baked-on type, very tuff ! The paint finish is a rough " fingerprint proof ", flat black. The " stamped " in ICOM logo on the top cover, is a nice change, but must have been abit of an expense to tool up for.
The IC-756, is a handsome looking rig, with a nice finish. I will not bother with the lab test results, which have already been published in QST. Please keep in mind that my statements are my own, based on my own thoughts & opinions, here for your consideration and judgment. I feel this qualifies me to make the statements I will make in this review. My background, as a reliable reviewer I have personally owned about 55 HF rigs, of all makes & models, many are good, some not so good. I like abit of practical application testing, and a little humor too. I am the typical, average ham that likes high quality gear.
I’m writing it from an average users point of view, not an engineer, or a RF lab tech, with use of allot of high tech test equipment.
