The Sherwood Engineering data says that for the 2 kHz spacing dynamic range test, the K2's performance was limited not by nonlinearity (intermodulation distortion) but by the K2's oscillator phase noise sidebands. The same table says the same thing about the Ten Tec Orion's performance in the

Thanks Ron, You've gave me some good information. Now I remember the filter and processor settings. I'll have to go tweak them and see what we get. I'm hoping the 12 uhenry inductor will give more range and will help stablize the frequency. Support also stated they had gotten some crystals t
