P3 No Longer Matching K3 Signal Level

My P3 always matched S meter signal level to the K3.

This morning with the S0 on the K3 ( with antenna disconnected) the P3 is
displaying a level about 7 db below the S0 level.

With antenna connected the K3 shows S7 while the P3 level on the screen is
slightly below S0.

What happened and how do I fix this?

73,

Bud W3LL

Re: P3 No Longer Matching K3 Signal Level

There's an explanation of the reasons for this in the P3 Owner's Manual
in the "How to set up and Interpret the P3 Display" section. Start
reading where it says, "You would expect the S meter on the K3 and the
signal on the P3 display to indicate the same level..."

How are Pre and ATT set? As I recall mine matches
only with ATT on and Pre off, but I've not looked
lately.

Re: P3 No Longer Matching K3 Signal Level

The P3 reads the K3 preamp and attenuator settings and adjusts its gain
accordingly for accurate amplitude display. The K3 can be set to either
take ATT/PRE into account to keep the S meter reading the same, or not,
depending on the SMTR MD menu setting. If set to NOR, that can be one
reason (among several) for differences in K3/P3 S-meter readings.
