I installed my P3SVGA today, and am observing a problem: 



Original state (pre-P3 SVGA install) 



K3 Firmware:  MCU 4.25, DSP 2.71, FPF 1.14  (IF level mod was installed at the time I received my P3, about a year ago) 

P3 Firmware: MCU 1.09 



Prior to installing the P3SVGA, the system worked according to specs. 



Current state (post-P3SVGA install) 



K3 Firmware:  No changes 

P3 Firmware:  MCU  1.12 



The K3 shows normal expected S-unit levels. 



In order to show background noise on the P3, I have to adjust the reference level very low.  My guess is that it is showing at about -9 S-units.  Local AM radio station shows on K3 as  S-9 +40 dB ; P3 shows it at S4.  This is on both the P3 display and the flat panel display.  They are "talking" to each other OK; it's just the levels that are extremely attenuated. 



Any ideas?
