       Please see info below about what I did for the definite lack of air flow within the K2/100.  I did not want to use any external fans.  Drift is still around 60 Hz but not really noticeable to other stations.
       I was able to find some aluminum screen gutter mesh at Sears hardware.  I cut the mesh to fit the K2 area between the KPA100 heat sink and the K2 front panel.  This replaces the solid metal front cover plate that comes with the KPA100.  I painted this mesh with black enamel paint.  It looks good and provides better air flow.  
       It looks like my normal drift is around 100Hz without any external cooling fan. I will continue to monitor drift.  This may be as good as it gets.  
       I have not had any comments from stations about drift either on CW or SSB.  I think that we may be expecting a miracle if we want to see much less that 100 Hz drift with the KPA100 unless further drift mods are made.
