    The details of what we did to improve the dynamic range w/o modifying the hardware is being treated as company IP (intellectual property), so we are not divulging the details.  Sorry.  I suspect our competitors would like to know how we did it also ;-)

    I think my question was misunderstood, not after how or what was done. As i didn't realize it was broke---:) Gerald, I'm trying to understand what this improved IMD will get me over what it was, sounds like it will give me better ears... Will what you did in v2 be included in the 1.11 maintenance release?

    Yes, you will hear weak signals better with adjacent strong signals (improved IMD DR3) and the strong signal handling capabilities (overload level) have improved, minimizing distortion at high signal levels.  It got better all around.

    Thanks Tim, Gerald broke down what the "improved IMD" gets me over what i have today... will this fix be included in the 1.11 maintenance release?

    Improved IMD may get you nothing or it may get you everything, it just depends on how harsh the RF environment  in which you find yourself.  I think the improved ADC overload may be as important as the IMD number I think both are impressive.  I have a 6300 and was considering a 6400 upgrade but since I almost never use the radio I may just go with a V 2 upgrade on the 6300

    What is intersting is why something has improved on my 6500. I saw Dave W2OX on air a few days ago and his IMD or transmition went way down through the noise floor. Now today I was on 40M and many said I looked the same,  something changed for the better.

    I'm inclined to wait for the fix to be ported to 1.11 maintenance release as i'm not after any of the new features in v2.

    Does it apply to 6300 only? 
  • FlexRadio Employee ✭✭
    edited July 2017
    That applies to the 6300 only because of its lower sampling rate.

    You probably would not notice a thing unless you had the lab equipment to measure it. It's the difference between your car being able to top at at 140 vs 150 mph.

    Bill, I believe you are observing the improved high pass filter cutoff on the digital transmitter filter passband.

    You *might* notice it in a contest weekend, on a crowded band with many strong signals. Or you may not. However being a contest op myself, I'd say that being able to use your radio is far more important than what it's capable of...
