K3 Power Changes When Driving My Amplifier

[pastormg]

Hi, this is Mark Griffin, KB3Z. I noticed last evening while on 40 meter SSB that when driving my amplifier that I had the K3 set at 48 watts input. As I was hitting the tune button I noticed that the reading on the K3 was now at 50 watts. But, when I took the amplifier off line it was back to 48. I guess I never noticed this before and maybe it's normal. Has anyone else had this occur? And, if so, is there a fix for this? Thanks! Mark Griffin, KB3Z

On the K3 check your CONFIG:TUN PWR setting against your power setting.

Yes, this is a very helpful menu item.  I normally keep TUN PWR set at 20
watts, which allows amp tuneup to be started at lower power with less
likelihood of damage due to a switching or antenna mistake.
