Funny -- I find the K3 user interface totally logical and easy to use. Once I RTFM through once and studied it for details, I only needed to use it to look up configuration changes or new features. L

Ten Tec made the Omni V. N4PY added a board that made it a V+. The used radio I bought had that board installed, and it added some useful functionality that made the radio a lot more user friendly. 2

5W at the antenna input. That's a LOT of signal. If it were to happen that I had signal overload, I would put the 20 db attenuator on. Or engage a bandpass filter if the signal is out of band. My nei

If the A to D has say, 1 mV per bit response, then the largest input signal this 16 bit A to D can measure should be ~65,000 mV. Thats about 96 dB. Hi Gary, I worked in pro audio, and thought the sam
