[Ham-Mac] Fldigi transmit issue

[Harry Mueller]

Good Evening All,

I have been experiencing some weirdness with my Yaesu FT-991 lately when using Fldigi (and WSJT-X) on my Mac where after a period of time the software will key the PTT but the no signal is actually being sent. The PO meter shows 0. To make it a bit weirder, if I boot up Win 10 via Parallels and use the windows applications this problem does not occur. I have already uninstalled and reinstalled both the applications and the drivers with no change.

I’d blame the radio, except that it works fine under Win10.

I would continue to use Parallels but my MacBook Pro is pretty old and performance with Parallels running is really poor.

Any thoughts on what is causing this behaviour?

Thanks!
