2009-07-02 Thread Joao Roberto S. G. Ferreira
Hello! After a while using D-Star and discussing the audio quality of each specific radio in our repeaters, we realize the following: - IC-91, IC92 and IC-2200 have the best audio quality. The audio is richer and have bass which others lack. It’s a common sense that the audio of

[DSTAR_DIGITAL] After all, how much is the real minimum Internet bandwidth for a gateway?

2009-03-29 Thread Joao Roberto S G Ferreira
I did all the tests of our gateway (PY2KCA) in my place with a 6MB DWN/1MB UP cable Internet connection. Everything worked fine. We only have the VHF module installed, since we want to install more D-Star repeaters and, for economical reasons, no extra modules will be installed in near future.
