There was a article on that some years ago but I'm lost the URL, anyone know it ? The conclusion was keep the receiver frequency steady and tune the transmitter. > Also I am hearing what I believe is both USB and LSB on the > birds. Is one sideband considered to be standard. USB is the standard for the Downlink. The sideband used for the uplink depends on whether it's an Inverting transponder or not. AO-7 Mode A would be USB uplink but AO-7 Mode B would be LSB uplink. 73 Trevor M5AKA _______________________________________________ Sent via [email protected].
