@vxo It can, but I think you have to scan the bird (or at least spot-scan the transponder) to get the service list.
It doesn't have a full transponder list - normally you scan the home transponder in Network mode (it has a list of homes and alternates) and it scans the whole orbital slot using the NIT data.
RSL is the usual percentage number, decibel C/N is on the second Info panel when you tune to a channel. Hit Mute if you don't want the channel audio.
