Yesterday I noticed in going from 100 watts to near a KW on
10 meters that when I turned my KPA1500 ON, the background noise
on my K3S jumped up about three S-units according to the P3.
Just turning on the front panel main "ON" switch starts the
noise even though the operate switch is still in Standby.
Then when turning the amp back off the noise fades for about
1 or 2 seconds before it drops out completely.
The noise is certainly enough to completely cover any weaker
10-meter signal. I checked for this happening on all other bands
and found no noise on any other bands. The noise is certainly
enough to completely cover any weaker 10 meter signal.
I have been using the KPA1500 for several years, and this is
something totally new which just started. Has anyone else
encountered this problem? What are other operators' thoughts?
