Strange P3 behavior

W4CCS
Gents:

 

Since I installed the KXV3B to add the second pre-amp in one of my K3's, I
have experienced strange behavior in my P3.

 

There seems to be lots of ghost traces (really bad when station has big
signal) as well as these strange "humps" on the scope. Makes no difference
if noise blanker (P3) is on or off.  use this K3 on 6 meters only. K3 # 1
without the KXV3B has no issues.

 

Anyone else experienced this or is this problem confined to my install.

That is interesting you should mention that.  I don't do a lot of 6
operations, but I also noticed a hump in the trace, that does not move
when I tune...  It is also there when I remove the antenna...  So it is
getting generated within the K3/P3 combo someplace...  

If I remove my antenna, I see it on all bands, at about S1, it does not
move on the trace when I switch bands, or tune...  

I only see it on 6 during normal operations because my background noise
is so low due to a crappy antenna...  :)
