Hi Ron & others!=20
      Please see info below about what I did for the definite lack of air=20
flow within the K2/100.  I did not want to use any external fans.  Drift is=20
still around 60 Hz but not really noticeable to other=20
stations..............................................................

      Hello to All!=20
       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=20
front panel.  This replaces the solid metal front cover plate that comes wit=
h=20
the KPA100.  I painted this mesh with black enamel paint.  It looks good and=

provides better air flow. =20
       It looks like my normal drift is around 100Hz without any external=20
cooling fan. I=20
will continue to monitor drift.  This may be as good as it gets. =20
       I have not had any comments from stations about drift either on CW or=
=20
SSB.  I=20
think that we may be expecting a miracle if we want to see much less that 10=
0=20
Hz drift with the KPA100.=20

73 & Happy New Year'

PS.   I am certain that Eric & Wayne are working on this drift problem!=20
