[Elecraft] K3: FT4 & RTTY Output Power

[john]

When I change modes from FT4 (Data A) to RTTY (AFSK A), I am only able 
to get around 0.2w output in RTTY. I have to recycle the K3 power, to 
get full power (100w) in RTTY. Any idea what is causing this, and if 
there is a fix other than a K3 power recycle? Both modes use the same 
audio settings, and are keyed via VOX. I don't see the power problem 
when going from RTTY to FT4.
