Tetra uses single frequency repeater in DMO mode, we do have a number of Tetra repeaters in OE land (and other countries) which work on one frequency without duplexer etc. those are even networked so when you talk on one in one city you are also heard on the other repeaters in other cities (or on mountains). Most Tetra terminals can act as repeater….

The Anytone AT-D578UV series of mobile DMR has supported SFR for years and, about two years ago, Radioddity introduced the GD-88 handheld with that capability. Radioddity advertised SFR as a huge thing, yet failed to be noticed by the ham crowd.

The main problem with SFR is that it needs to be supported by the code plug of the handhelds connecting to the repeater. It also needs the handhelds to support DCDM (Dual Capacity Direct Mode), not all do.
