This is a normal limitation of the current software & firmware.Dave30019 wrote:No side tone in CW using CWX & 'SEMI' after Thetis and cmASIO upgrade. I do have sidetone if CW is set to QSK and also pressing TUN but not in SEMI mode.
This issue goes all the way back to the beginning of the openHPSDR project. The developers at the time did not feel they could implement sidetone with low enough latency if the sidetone audio was originated in Thetis. Thus they had the firmware generate the sidetone and that sidetone is only available on the audio interfaces that reside on the SDR board, i.e. the ANAN speaker and headphone jacks.
There are several ways to solve this problem, but nobody had thought of them way back when and to date nobody has seemed interested in tackling this problem. If anyone would like to try to write some code on this I've got a few ideas that shouldn't be too terribly difficult to implement.
If you want to use either VAC or cmASIO with semi-break-in CW then you will have to provision an old fashioned sidetone (aka "practice") oscillator on your key/keyer/paddle.
