Hello all..    This AM on 160 meters there was a station CQing on 1.820.6 with 
a fundamental freq signal strength of S9 on my K3.  I also found (with the NB 
on) that I could hear him Q5 but very weak on 1.810.6 and the same S 0 reading 
but perfectly Q5  on 1.830.6.  I turned the noise blanker off and of course the 
images disappeared.  Is this a know problem when using the NB or is this just 
with my radio after a recent factory alignment?   I have had a K3 for years and 
never noticed anything like that before but then again this AM was very quiet 
on 160M and I had the NB on because I could hear a distant tick tick of an 
electric fence.
