I didn't even hesitate adding the KXFL3 to my KX3 order. I may not notice much up here in the "sticks" of Alaska, but the KX3 will travel with me to the lower-48 and why compromise? The other option was the MH3, mic. I opted out of the paddle-key and internal tuner as I do not anticipate ope

Don, Dynamic Range is the range between the minimum signal that can be received to the maximum signal level that causes compression of the radio output. A greater dynamic range means that you can listen to two signals in the passband, one quite weak and one quite strong without overloading the

Don: Dynamic range is the ratio or the largest signal to the smallest signal that the receiver can properly handle. The low end of dynamic range is smallest signal that the device can detect, and in analog gear like an amplifier or mixer is usually determined by the internal noise generated by

Don Having owned both a k2 and an an 817, i can say that in terms of working pile up which happens during contesting or sprints and you want to be competitive in bagging who's then it is absolutely no contest because you can pick apart a pileup with the progressively narrow filters better. Als

Ok I admit I do not clearly understand this 30dB better dynamic range. Can someone put it into terms what this really means on the RX side of things, when you would be in real world operating conditions. It does not have to be about these specific radios listed in the post below, but what does
