PSK and AFSK
« on: 2012-04-18, 15:51:20 »
Hi

I did some brief tests of the new version, and it is great! Thanks for the update.

I haven't tried it yet, but is it possible for an AFSK or PSK software to access the audio device in the dongle?

This would open the world of digital modes with the PC-client.

I have a Microbit RRC pc-client running and it creates a Microbit 1274A sound device on my Win XP SP3 pc. I run HRD+Digital Master 780 and in DM780 I can select the Microbit 1274A sound device. It can display a waterfall form the remote radio, but it does not decode PSK31 reliable. The volume controls in Windows for the Microbit 1274A sound device seems to be reversed, that is in DM780 the TX volume slider controls the loudness of the received signals in the waterfall. The traces in the waterfall looks distorted and I have not found a way to decode them 100%. I can turn the audio level down but the signals still looks distorted right until they disapear. My SignalLink at the radio site decodes much better.

I have not installed a virtual sound cable, but it seems Windows has a similar feature as I have to enable a slider called 'Hent' in my Danish Windows. The English meaning of 'Hent' is something like 'Fetch' or 'Get'. After TX'ing this 'Hent' slider has a tendency to disable it self so I do not get anything on the waterfall.

How is the Microbit 1274A sound device supposed to be accessed from DM780 and other digital programs?

Hi

It's not possible to bridge soundcards in Windows (as we are aware of at least) so, you must use one other soundcard (for example the internal ) for the PSK program and connect analog cables to the 1274 dongle.
