No TX audio on LTE

Chris Knox · January 2021

I am having an issue with Smart SDR for the iPhone. When I am at home on my LAN everything works fine. When I am on LTE I can connect to the radio and listen but have no TX audio. If I connect my laptop to the hotspot on my phone it works fine. I have checked that I am using the right mic on the phone and have allowed access to the mic in the iPhone settings. I have checked my port forwarding and it is fine. I have connected to a friends flex on my iPhone and it works fine.

Any thoughts?

Have the same problem with mine on Sprint. My audio is intermittent. Sometimes it works other times it does not work. If I use a hotspot and connect to the hotspot's wifi it works but won't work direct on LTE on iPhone

[{"insert":"Any word on this?\nIm having the same issue. I can actually see my audio peaks in the meter\nbut nothing transmitting from the radio. \nThe radio keys but no output.\nCWX works but no SSB. \nVery frustrating. I bought it just for remote access \nand can’t do it with my phone.\nI also checked that DAX is off I selected iPhone and can see my voice peaks on the meter.\n\nThanks,\n\nHarold Johnson\nN8RQJ\n"}]
