Never mind. My math mind is as bad as yours today. There is 150 Hz of
separation between what I assume is the 3 dB points.
Sorry

Ok. I am having a world of problems today, the main one being

I have a basic bandwidth limit that I am hitting and for some reason I
cannot do basic math today.
I am trying to see how many carriers I can transmit on. I am mixing a
single gmsk modulated source with LOs in software and seeing how many
times I can do that. A single channel is 250kHz wide and the channels
are 400kHz apart center to center. In other words my LOs are 400e3,
800e3, ...
How many carriers would you expect that I could transmit on?
Thanks
Jeff
P.S. Sorry in advance, I am nuts today.
