I have used the iFTx app along with a lightning connector to usb adapter to successfully operate FT4/8 with the iPhone and QMX.? The first adapter I purchased did not switch the audio path to the lightning connector.? I purchased a second one that included the audio path in the product description and it has worked well.? The VOX must be enabled in the digital interface menu on the QMX.? Here is a link to the adapter that has worked for me.
