P3 Relay clicking , diplayed curve while tuning

Michael van Hauten
Hello elecrafters,
my new P3 works fine. Very often i hear a relay clicking inside the P3. Is there anything not adjusted? Is it possible to stabilize the displayed signal curve during tuning? During Tuning the display shows like average is set to the lowest level. I'am not abel to detect signals. while tuning. Any hints for adjusting the P3?

That's probably the relay that bypasses the amplifier when very strong
signals are present.  Try turning off the K3 preamp or turning on the
attenuator.

The averaging resets when you tune.  That keeps the display from
smearing but does cause the displayed noise to increase while tuning the
K3.  Once you stop, the averaging resumes automatically.
