GD-77 Won’t connect to PC

I have been using my Radioddity now for some years and love it.  Though upgrading this to the OpenGD77 opened a whole new world and it gets better all the time.

One issue I had for a period was not being able to connect to it via my PC. For some time, it worked, then it stopped. It was most frustrating as I could not run the radio as a local repeater anymore. I almost never update the codeplug now and update the firmware every few weeks, but I could not do any of this without my PC connection.

After checking I had the latest community programming software, I was stumped.

Roger, who is behind all the programming of this radio and who lives nearby, kindly gave me some advice over email.  He suggested it was a Com-Port issue.  And he was correct.  So, I have put this together to help others who may have the same problem as I did.

From windows 10, type in the search box Device Manager.  Then you will get a box like the following.

If you expand out the Ports section, you can see the issue I had straight away, I had the OpenGD77 on com port 4, and an Eltima Virtual Serial Port on com port 2-4 also.

I disabled the Eltima com ports listed by right clicking on them and nothing seemed to stop working, so then I uninstalled them both.  And straight away the com port worked through to the radio like it used to.

Great to have my GD77 back in action!  Hopefully this has helped you, if it has, please let me know.
