There is NO ALIGNMENT for the
carrier oscillators. They come from a DDS chip controlled by the uPC.

Cliff-

I've lately had a problem with my old IC-706, after a hot day in the car. With
the IF shift set to the mid-range detent, there is a very noticeable difference
in the sound of received noise when switching between upper and lower sideband.
Could that be due to a bad SSB filter? Could that be the same problem Chafik
is having?
