As the subject suggests, I'm becoming more convinced every day that the K3 is a terrific radio and a good value. This week, Elecraft released new beta software that includes new features that have been added. If this was Yaesu, Icom, or Kenwood, it would be a new rig version that you would have to purchase. Here are the new features:
Audio Peak Filter - for CW only, you set the filter wide and if you hear a really weak station, you can center your dial on him, turn on the APF and it will automatically create a dynamic filter that increases the gain on that one station. The filter shape can be described as sort of an inverted V over that signal. I'm not a big CW guy, but users who have tried this feature in the beta release have said that it works significantly better than the same function in the other rigs they've tried it on.
TX "Fast Monitor" - Previously, the voice monitor had a bout a 20ms delay which lets you hear how your on-air signal will sound. This is cool, but annoying if you just want to hear your own voice in the headphones. Now you can set the monitor to kill the delay so that it is real time.
They also made some improvements with the Noise Gate to give it a smoother response. They say the performance is improved near the threshold, but i haven't tested that yet. I will soon. They also got rid of the the pop artifacts that happened when you adjusted the shift and width of the filter when using very narrow DSP filters.
The beauty of a Software Defined Radio...
