KXPA100 low out on 30 and 15 meters

[Jr]

I bought used the KXPA100 with ATU.  The KXPA100 puts out less than full
power on 30 and 15 meters. The other bands the KXP!00 puts out 100 watts
and a bit more.

Both thte KX3 and the KXPA100 have the latest firmware installed.

This according to the LED's on the amp and connected to an MFJ dummyload. I
don't own an external wattmeter. I've run through calibration several times
and the overall results remain the same.

Any help would be appreciated.

Thanks and 73

Eddy,

How much less than 100 watts.  You can figure there may be an up to 20%
error in the KXPA100 wattmeter reading - which will vary from band to
band.  Are you seeing at least 80 watts?  If so, it may be that all is well.
