so I know you all will laugh at me but what inverting means lsb down usb up is this correct
It means that the signal sideband is inverting upside down in the satellite. It inverts USB to LSB and LSB to USB. It also change your frequency polarity. If you increase your frequency at the uplink, it will get downwards the same amount at the downlink. It is "mirroring" all signals. And converting them to an other band at the same time. :)
For the birds (and I'm relatively new to this as well) I transmit LSB and receive USB - am I correct in thinking this is the accepted default or does it vary from satellite to satellite?
