Re: Problem Connecting ThumbDV to BlueDV for Windows

Glad to be of help! By the way, I am one of the net control operators for the Georgia statewide DMR net on Wednesday nights at 8:00 p.m. eastern time on talk group 3113. By coincidence that just happens to be an hour and a half away if you want to join us!

Thank you! Switching to 460800 did the trick… and unplugging/replugging the ThumbDV.  Now to get the rest of the configurations completed.

Yes, only very early ThumbDVs use the 230.4K rate.  Switch to 460800.  You may need to unplug and replug the ThumbDV, after changing the baud rate, if you used the wrong baud rate.

Which version of the ThumbDV you have? I believe newer ones use 460800 baud rate which is not selected in the config you provided.


Have you tried switching the baud rate?

Just got my NWDR ThumbDV (DV3000U) dongle in the mail today.  I need the most recent installation instructions, please.


I tried to follow some dated YouTube and other online resources but to no avail…  My Windows 11 Pro (64 bit) PC has BlueDV for Windows (Version installed (and reinstalled), but it will not connect to the ThumbDV dongle on USB Serial Port (COM4).


Any help would be appreciated.
