[Elecraft] Power problems K3

[SouthCarolinaDolphin]

A friend is using my K3 while his is in the shop When he transmit's on the K-3 running a specific power out he notices that the power especially on  RTTY will start at a lower output that what was dialed in and gradually raise its output to the maximum dialed in. This seems to be worse on 15 m. It only appears to happen once then will not repeat on same freq. So if a specific power like 100W is dialed in watching his W-2 watt meter the power may start at 60 watts then ramp up to 100 watts usually on RTTY.
Any ideas. Thanks
