Thanks for all your answers everyone.

Hi

I have an SB-303 and SB-401 working together as a transceiver in ‘locked’
mode with the (same) operating frequency for both the Rx and Tx controlled
by the Rx.  Can someone explain to me why the LMO frequency on the SB-303 is
suppose to change slightly when moving between USB and LSB, please?  I
thought I sort of understood this one time.

Thanks,
