[Elecraft] Rising current on Tx (K3)

[Iain G4SGX]

Apologies if this is covered before.

I've just noticed some new behaviour on my K3.

While on 10 RTTY chasing DX, I noticed the current indication on the PSU 
rising during a long TX.

I switched to the current meter on the K3.

At the start is was about 15Amps (100W RTTY TX) but soon rose.

On a 20 second TX it rose to about 26 Amps (!) and the Hi Curr error 
message came up on screen.

The rig USED to be OK for extended periods of RTTY.

I have not tried on any other bands.


Can anyone explain this behaviour?
