Can some one explain how to use the zero beat and offset controls on
a Century 21? It is a DC receiver and different than I have ever
used. I know that pressing the zero beat button disables the Offset
control. I know that you tune the CW sound until it goes down to
point that you can't hear it. If you continue to tune you hear the
CW begin agian going up in pitch. So you back up until it can't be
heard again. Then you tune the Offset until it has a pleasant
sound. The offset it tuning the reciever only and the transmitter
stays zero beat correct? Is it that simple?
YES
Why the +/- on the offset? is it so that you can listen to either
side of the CW from the Zero Beat point and maybe get away from
other transmissions on one side of zero beat or the other to help
eliminate QRM?
YES
Curron, I think you've got it.... yes, you've got it! (As Prof Henry
Higgins said to Eliza)
Have fun,
