Building an MMDVM based Quad Mode Digital and and SVXlink Analog Repeater using a Kenwood TKR-850. Due to the lack of Digital Mode repeaters around my home QTH, I had been running MMDVM hotspots built around Philips / Simoco PRM80s on 2mx and Philips FM92’s on 70cm for around a year, with G4KLX based DSTAR hotspots using soundcards or DV-RPTR boards for several years prior to that.After the article on the configuration and installation of a Nextion screen on a MMDVM repeater, let’s see together how to integrate a small OLED display on MMDVM. This type of display is known by the reference SSD1306, it measures 27 millimeters for a display definition of 128 x 64.About the first repeater (W9YT, the one works with Anytone but not with 7550): It’s a somewhat funny mixture of a Kenwood repeater and an mmdvm host. Here are some details about this setup. The second repeater labeled itself as a DMR Marc repeater, and the handshake seems to be successful for both Anytone and 7550 on that repeater. However ...Step 4. Install and configure MMDVM and MMDVMHost (i will not cover this, there is plenty of info around) Modem config in MMDVM.ini.
