Hi,
Following F. Cady advice on grounding the station equipment to a common
bus, I did so. My set up includes a KXPA100 with the ATU, the KX3 and PX3. Now
I noticed that the KX3 does not always indicate the same antenna as the KXPA100
when I switch bands. Sometime it does and then does not, or will change after
5 to 10 seconds. I have a Vertical for 30 meters, and a Dipole for 40 and 20
meters, the KXPA100 switches immediately.
I have powered down all the equipment, restarted and sometime this does the
trick and all is well. But sometime it does not. If I remove the ground from
the KX3 and the PX3 the issue goes away.
The equipment ground is #18 stranded, < 10” to the bus, the bus has a copper
braid to the KXPA100, the antenna grounds and on to the station ground rod 8’
feet outside the shack.
At the moment all is OK. I just do not know the root cause. Any ideas or
thoughts.
