Hi,
I noticed that SWR change in my K3 if I use the amp or if it´s in standby.
For example in my 20 mts yagi, the SWR with the antenna direct to the K3 is
1.5:1.
If I put the antenna through he amplifier, in STBY the SWR is 1.5:1 but with
the aomlifier is in Operation the SWR is 2.0:1
Jorge,
With the amplifier in standby, the K3 wattmeter sees the antenna SWR -
the same as when the antenna is connected to the K3.
When the amp is switched to operate, the K3 will see the input SWR of
the amplifier - and that has no relationship with the antenna.

Hi,
But is it normal for the KPA500 input SWR to be 2:1?

He did not say it was a KPA500! Maybe it was some other amplifier that
we cannot comment on.
If it were the KPA500, I would have asked what bands.

Did you leave the K3 tuner online when bringing the amp online?
The K3 tuner should be OFF when using an amp. Another DOH! moment?

The amplifier is a Drake L7
I will test with a ALS1300 to see what happens
So what do you

He says it is happening with an Alpha 89 too. Something is not right.
