Hi Stan,

Adjusting the ref level does not help. Looking at the IF output of the
P3 the actual signal level is not changing when I switch between 6m and
2m. I hooked up my QS1R SDR and can see the signals fine when the P3
water fall display is orange when I am on 2m. I can not find a ref level
that works. Radio is working fine on 2m as I can copy signals fine.

When i disconnect the serial cable between the P3 and K3 the display is
fine minus frequency and filter info of course.

All the software is up today. Both of my K3s do this.

Any ideas gang??

73, tom n4zpt
