Re: Freq Chart for AO-40??



Those numbers are consistent with what I first posted, Don. I did it the
hard way, but the result is the same. I added your little formula...which
should have been obvious to me in the first place. Now I can type in either
an uplink or downlink and see the result right next to the larger lookup
table.

Thanks!
