[Elecraft] XV222 Transverter Stability Issue

[Lloyd Korb]

I recently completed the assembly and calibration on a XV222 transverter.  I
am using it with a K2.



When I finally put the top cover in place I noticed that the output power
was jumping around.  Initially I thought that one of the connecting cables
were not properly seated or maybe the output cables to the wattmeter and
antenna were not tight.



I noticed that when I picked up the transverter, to move it, the power
output jumped around.  Pushing on the top cover also made the power output
jump around.



When I removed the top cover the output was stable.  I could push on the
chassis and it did not change the power output.



I thought that maybe the top cover was not making a good RF connection to
the rest of the chassis so I went back and cleaned and sanded all of the
mating surfaces.  This had no effect.



As long as the top cover is not in place it is stable.  For now I am just
running with the cover off.


Has anyone had a similar problem?
