William,
Check the soldering carefully, particularly on the Control Board. Also
check and re-check the placement of the components mounted on the back
of the Control Board (they are part of the power control circuits).
Check soldering, then re-check the soldering, and when that is finished,
check the soldering.
Good luck in finding it.

I am having a problem with output power stability. Example: Power set to 5
watts. When transmitting (into a dummy load), power out is all over the place,
from as low as .2 watts to as high as 12 watts. This fluctuation is very rapid.
Measured current (at the P/S) fluctuates with the power output fluctuation.
Can anyone give me an indication of any possible cause and solution?
Thanks.
