Re: Battery for QCX?
The pack I pulled from the handheld vac used three cells. I have used the QCX with a 8 AA pack so I guess I should add ?a diode to drop voltage. Thanks. Just concerned about the moisture warning.

Re: QMX and FT8CN fix?
Set both threshold levels to 0%. it will now work I think that there is a lag between FT8CN sending the PPT, and audio. So that the QMX/QDX thinks there is no audio. Philip G7JUR
