Mmdvm repeater.
One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola). This is a large and very visible forum.
For digital voice modes, hams have choices of D-Star, DMR, System Fusion, and others. An open source project, the Multimode Digital Voice Modem (MMDVM), allows you to use multiple modes with one ...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.Each BCR Repeater includes FREE Programming!

Designed and assembled in the USA. 2 - year warranty.When interfacing an MTR2000 station to ANY external repeater, D-STAR, DMR, or MMDVM controller, make sure you've set the station configuration (Repeater / Base) to BASE so the station looks like a fully independent full duplex receiver and transmitter. This configuration setting removes the internal repeater controller from the audio and PTT paths.Attenuation is a term used to describe the gradual weakening of a data signal as it travels farther away from the transmitter.
