I am just trying to directly answer the questions in the original post: ============================================================================ John Kristian

Will Direwolf on Windows work with an audio adapter model DRA-65 or DRA-70 from ? These adapters have a ,
but it requires sound output on both left and right stereo channels.
One channel goes to the radio, and the other channel triggers PTT when
it detects output sound. Perhaps the question boils down to whether
Direwolf can be configured to output the same audio on both stereo
channels.
These adapters can also trigger PTT from the GPIO3 output of the CMedia CM119A. But Direwolf on Windows can't use this method, says the User Guide. ============================================================================ So again, the request from the post was 2 fold: 1.? Will Direwolf on Windows work with an audio adapter model DRA-65 or DRA-70 from ? A:? From WB2OSZ: When an application opens a stereo audio output device in mono mode, the same thing comes out of both audio channels. My response: I believe applications which use the second audio channel for PTT do not send the same audio to both channels of the sound card. As
I recall from the FLDigi information, the second channel starts before
the data channel (PTT delay).? Keying the rig and starting the data
signal at the same time is typically not a good idea.? I am sure it
holds the PTT a short time after audio completion as well.? This PTT
signal is commonly only a single tone (:) But, if as indicated above, Direwolf DOES send the same audio on both channels at the same time, this is not an optimum configuration for PTT.? The PTT needs to go active BEFORE the audio.? I was pointing out that "I" felt he (John Kristian) would be disappointed if he tried to use his Masters Communications VOX circuit with Direwolf on the second of the stereo audio channels. There are other discussions on using the CMedia GPIO on WIndows computers. Robert Giuliano KB8RCO |
