[Elecraft] [Elecraft-K3] Interesting P3 Anomaly
Yes, what you're seeing is IF leakage, not the RF signal. The level level is uncontrolled and depends on the isolation of the PIN diode switches, etc.toggle quoted messageShow quoted text
Yes, you can see it by transmitting, with the RS-232 cable that normally goes between the K3 and the P3 temporarily disconnected.
Because it is the IF signal, it doesn't show distortion caused by the transmitter PA. Still, it does display the frequency response of the transmitted signal, which can be useful when setting up the TX equalizer.

Don't know what you mean "doesn't represent your transmitted signal" It is leakage of your signal at the IF, I see it with my SDR that is tied to the P3 IF out and it looks exactly like the signal I see on a spectrum analyzer using a coupler.
