                Posted - 05/02/2024 : 09:25:13  After reading the manual that comes with the unit it identifies the usb c port but the other port does not seem to be identified.  Is the other port a headphone port? Some kind of grounding port?  or something else?
  Thanks. |

                Posted - 06/20/2024 : 14:09:59  Thank you, I was also searching for the use of that port.
  A teardown video or thread of the GQ EMF-390 was one of the first things I searched for, but I didn't get any useful results until I found this forum, which at least provided some pictures of an EMF-380. Is the EMF-390v2 build just like the EMF-380, with out the 0-10ghz detection? |
