Hi Robert,
Not a direct answer to your question---but AO-51 doesn't require any subtones for operation at this time :)

I am using SatPC32 to control a pair of IC706MkIIG's. The CAT control with the SubTone "T" feature does not enable the subtone when trying to use AO-51. I enable the sub tone on the IC706 Uplink xcvr, toggle the T button to T1, but as soon as CAT control changes the frequency to allow for doppler shift, the tone function is disabled in the xcvr by the program even though T1 in the program is still enabled. What is the correct instruction code to enter in the SubTone.SQF file in SatPC32 for the IC706. The current command line in the file reads: AO-51,67.0,$3F,1. Any help is greatly appreciated. 73, Robert W6RQR
