My old company, Sepura, entered the Digital Mobile Radio market last year (as an addition to the TETRA products they already design and make) and are, as we speak, designing DMR products for sale in the near future. In recent days they've had a wake-up call from their major competitor Motorola in the form of two new DMR radios that set the benchmark. See http://www.motorola.com/Business/XU-EN/Product+Lines/MOTOTRBO/SL4000+Series/SL4000_SL4010. These look very attractive products and I am glad I no longer have the task of trying to beat them! Instead I can tinker with lightbeams and VLF.
