It's something I might use, when using a conventional radio interface with soundcard audio feed. Would save hunting around for a USB audio device and having to make do with headphones. However, when using my FT-818 that's not an issue, because with that radio, I use the SCU-17 interface, which has a USB sound device. > 2.

As I use Windows for end user applications, I think "probably not", unless I can do some funky magic with VoiceMeeter and multiple virtual audio devices. -- 73 de Tony VK3JED/VK3IRL http://vkradio.com |

One possible use case would be with the UDRC or DRAWS: analogue headset into one of the ports and radio into the other. However, USB audio interface, USB headset, or even Bluetooth are viable alternatives that require zero changes to FreeDV. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. |

The only nice use I would see is if someone can use a SBC without integrated audio, it would be possible to use a single card and a hardware switching system that would follow the ptt switch in the software to switch the microphone input between the radio output (in receive mode) and the analog mike the ham will use. The stereo output would either feed a small speaker for the decoded/encoded audio and the other channel could send a tone when in tx so that the switching circuit could detect when in tx and put the ptt switching circuit in ptt mode and mute the audio signal to the speaker so not to ear the transmitted modem signal. Kind of a vox system. Why have a full duplex audio system when it is not needed. We either receive and decode or tx and encode. Le mardi 16 mai 2023 à 18:02:16 UTC-4, Mooneer Salem a écrit : |
