well, if you turn the AAT off, then you'll have no more AAT, it would be,
turned off...
Its sort of like the power button on the radio, if you turn the radio off,
the radio doesn't work anymore, if you turn it on, poof it works
again...same thing with the internal AAT.
That is why the manual refers to it as the AAT bipass function.
The relays click as you go through the different band segments...usually
it'll click when you go from the CW portion to the phone portion of a band.
Absolutely nothing wrong with that, and it is in fact designed to do that.
As for the headphone/external speaker jacks, well, a headphone output is
designed for a 32 ohm load, and generally has an attenuator, in the form of
a resister, to prevent ear damage.
The external speaker jack is rated at 8ohms and doesn't have any attenuator,
so you will get full volume, or at least, very similar volume levels from
the external speaker as from the internal one.
Just a note on the headphone jack. someone mentioned that it is a stereo
jack and that putting a mono plug in would cause a short, and perhaps a
volume loss...in reality, i believe the headphone output is likely a split
mono signal, and it is designed to short the right side to ground and send
the signal out the left side if a mono jack is inserted.
Most audio devices with stereo, or split mono out puts are designed like
this in the eventuality of a mono plug being put in.
Even computer sound cards that have 3.5VDC going to the ring of the
microphone plug will just short to ground if a mono plug is inserted by
accident...
They probably just use some sort of bleed resistor and a small heat sink to
accomplish this.
