[Elecraft] K3 RF-out spikes, was: K3 SSB Power Control and ALCMetering

[e72x]

Hi,
Spikes are visible on both power meter on K3 and I can see on external Watt
meter including "error message"  from automatic amplifier which get response
- Overdrive Input is to high!
I am forward message from Elecraft support!
it is helpful to press TUNE when the rig is first switched on, for the
quickest and most accurate RF output on later transmissions in SSB, CW, or
data modes.

E72X,
Gordan,
