[Elecraft] Speaker + Phone

[Wes Stewart]

I normally use a headset while operating.  Now that I'm dabbling with RTTY there seems to me little need for this, however, I would still like to hear the audio while tuning around.

My headset is plugged into the rear headphone and mic jacks and is a pain to unplug so I've set the config to speaker + phone, but it appears that this doesn't work (at least on my K3) using the internal speaker. 

Is this normal?  If so, how come?
