Buster is an application that allows amateur radio operators (hams) to access the D-STAR digital voice network from their Internet connected Mac. The program requires a hardware encoder chip to translate the audio data into the required AMBE format for transmission on the D-STAR network. Buster currently supports either the ThumbDV or PiDV over the network. These products are available from Northwest Digital Radio (

Buster supports all three major reflector protocols (DPlus, DExtra and DCS) plus the ability to link to repeaters.

Broken on High Sierra

I just upgraded to High Sierra and this app no longer works. Crashes on opening every try. Update soon ?

I can hear, but no PTT

Well I was excited to see this app available, my ThumbDV has been sitting around doing nothing for a long time. I installed the app, it found the ThumbDV and I was able to add repeaters and reflectors. What I can’t do is transmit. The app sits at “Connected to . Attempting to establish link.”, the PTT is greyed out. Problem is all the links for any help don’t work. The internal help says “Help isn’t available for Buster” and the Apple support links go to the author’s site and fail with "502 Bad Gateway”. Maybe this is a temporary issue, or the project has been aborted. Anyway, I guess I’ll just listen for now. KB5TDJ.

Finally Can Use My ThumbDV On My Mac

I can finally use my ThumbDV on my Mac. The application is deceptively simple and works great. I really like the fact that it is so simple and that it keeps a running log of contacts. If the contact is publishing their location, you can get a nice map of where they are located. I hope the developer continues the development to work with other dongles as well.
