OpenGD77

It's was fantastic and brought out the best in the radios but ever since the little illegal ordeal I cannot connect open GD 77 to any of my DMR radios,, it registers a com port but when you try to use it it says it cannot communicate? truly sad

are you using OpenGD77 firmware? I suspect these posts have more to do with frustrations vs actual problem resolution for your connectivity. but ...make sure you're using the proper firmware first. you say com port when you attach it to your PC

in windows device manager computer management do you see a device as a port? if no you have driver or cable or PC issues to resolve first.
