I am in the testing phase of my KPA-100 construction using an Astron 20A
power supply. When I attempt to adjust the power of the K2 in Tune mode it
will reset at levels between 40-90W depending on the band selected. I tried
adjusting the power using a battery and I was successful to 100W without
having a reset. Therefore the problem points to the Astron. Tech Support
mentioned to me that this is a problem that has happened a number of times.
I have tried ferrite beads on the DC lines, a capacitor across the '+' & '-'
leads and verifying that the '-' lead is connected to the case (a solution
that I found on the web). Nothing has helped.
I haven't found anything on the discussion list addressing this issue. Has
anyone had this problem ?
TNX & 73, Jim
