Re: Over the moon !
Nice result. QRP RIG with a dipole for G to VK CW QSO. Between the 50 Hz and the 300 Hz filter BW there is almost 8 dB difference in dynamic range. This is in the range of a beam antenna gain compared

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.

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
