Select Soundcard in the menu on the left. When the Program Options dialog opens, follow the steps below to configure assign the soundcard in the radio to be used for the audio device for receiving and transmitting the digital mode. So from my experiences of over a decade the internal sound cards work.maybe missing some weak DX at times, but then again maybe not. On the DM-780 main toolbar, click on Program Options. Digital is from the back of the K3 directly into the mic and headphone jacks.Not one issue. You should see a waterfall moving in DM780. 7) Digital Master 780 should be configured to work with SmartSDR at this time. Select COM5 and make sure 'Set DTR / Set RTS' is checked as well. This problem doesnt occur on 2015 or 2017 Macintosh systems - just the 2018 systems equipped with a T2 processor. Select 'DAX Audio RX 1' for Input, and 'DAX Audio TX 1' for Output. My Singlink USB is used with my ICOM 756PROII. These pauses are often long enough to cause an audio overload. It includes two separate bridges: - A bridge between DM-780 and DXKeeper that is used to log completed QSOs as well as perform log lookups. Never once had a problem using direct connect. Download popular programs, drivers and latest updates easily DM780-DXL is an interface that facilitates use of DM-780 with the DXLab suite of programs. I have been doing PSK31 since it came out with dozens of table top, laptop, netbooks and one ACER W3 8" tablet. All with a TV looking antenna at 9 ft about a wooden desk and 12 ft above the ground for 30 days. All I know is it worked and worked very well and I made a ton of contacts all over the US on 3-5 watts and 25 watts. Maybe the sound card was not top notch, maybe it is better then either of us believes. I dug up a photo of my setup when I was in TX. I use the USB port in the KX3 to talk to HRD or mostly Win3K3suite to make life easier when dealing with SSB and the limited CW I do. I have done that, as well as the CW qrp, SSB qrp and other frequencies. This prevents the computer from overload- ing the radios input stage. Rig control for PSK is not really a must have since each band is pretty well defined and can be stored in the KX3. If youre using a line level or patch input to the radio, make the series resistor 1K. The sound cards in a laptop like I used might not be super gee-whiz, but then again the Signalink USB is not either unless go inside and modify it with the resistor mod.
