Mark, not sure if this was meant for me (as I mentioned tone not working well) - but I am not using SatPC32 - instead I am using Gpredict. Alex Csete (the software creator) has suggested that this may be a limitation of his and/or Hamlib software. It's typically not a big deal for me as I usually use a single TM-D710g for the FM sats. And when I use the Icom for Tx on the Fox satellites, i can usually rely on somebody else triggering the tone requirements.

If you set Tone ON in SatPC32 it will keep it on in the rig as frequency changes.
