Fair enough - several audio analysis/test  progs have the facility including Alberto's after my request a while back.

 

Hadn't realised Spectrum lab had Digimode facilities, but I don't use that package very often.   Find it too complicated to use when all I want at any time may be a spectrum analyser, or a data decoder, or a tone generator.   Easier to call-up a different custom package for each one, and run several in parallel if necessary.
