I think I have seen what you are talking about.? ?I use homemade soundcard systems rather than Signalink.? ?I prefer to run WINLINK etc from my computer and then treat the SBitx DE as just a SSB transceiver.? ?Ihave to run the audio? output of the homemade soundcard system TO THE MAX to get useful output, in fact I have it only my list to change a resistor in it to get even higher audio ouput to have more RF output.? ? This is prrobably just a coefficient somewhere in the coding.? ? Running high levels of audio voltage can be seen as an ADVANTAGE because it makes it less susceptible to common-mode interference, that is the bane of digital hams everywhere, but it does surprise one at first.
I have not delved into the code to see how the audio is handled for the Digital, I think I probably just use USB, actually??
Hope that helps,
