The same can be done with about any analog radio in simplex mode.The WE0FUN Fun Machine repeater system was the first in Colorado, and among the first in general (to our knowledge), to create a truly mode agnostic repeater system that can be accessed from anywhere in the world using any of the common digital modes (NXDN, P25, DMR, DStar, System-Fusion "C4FM", M17) or analog via AllStarLink.Beginning in late 2017 we started to bridge and add digital ...The 878 has a ranging mode which will periodically check if you are in range of the repeater- if it doesn't get a "handshake" back it will tell you. In theory it's a nice feature but kind of annoying in reality. Since you said "I can hear the analog side" I'm assuming it's cheap MMDVM repeater, running in dual mode.MMDVM board for Arduino Due. To build a multimode digital repeater, G4KLX have developped a complete software called MMDVM ( Multimode Digital Voice Modem ). It is compatible of main digital modes (to date, C4FM, DSTAR and DMR). This board interfac on one side transmitter and receiver and, on the second hand the Arduino Due.After you get your MMDVM repeater put together, the last important step is to tune the audio levels. Digital voice can be very picky when it comes to audio levels from a repeater standpoint. If the raw audio is either too quiet or too loud, subscriber radios will not decode the digital signal properly. A common symptom of an improperly tuned ...
The Repeater-Builder STM32-DVM is, we think, the best MMDVM Modem board out there.
