Hi Dave, The P3 is quite good for measurements, and the SVGA card is even better. Here's a collection of work I've done with whatever rigs and amps I could get my hands on to measure. http://k9yc.com/P3_Spectrum_Measurements.pdf In my experience, if you keep the K3 within its linear

[Elecraft] P3 Phase noise/HighSignal Response?

2017-03-13 Thread K5MWR via Elecraft
I am trying to use my P3 to evaluate signals from other hams here in my community. While I know the K3s is excellent, I am not sure what to expect out of the P3 in terms of phase noise or response under high signal conditions. I can always pad to lower the signal but that will not help with
