Hi I have connected every cable from the Digimaster except the audio to/from the computer( aspire one) sound card. and can receive OK. But and not sure I am Tx ing. The rig switches over OK. Does the transmission come from the computer via the Data port connection or via the output from the soundcard? I think the audio from the rig goes via the Data port because the volume control has no effect. So next question how do I control the input level? suggestions welcome Terry G3WDI
