This USB hotspot will do D-STAR, DMR, C4FM, P25 and NXDN using either the appropriate UHF transceiver or directly with your PC's microphone & speakers. The on-board AMBE vocoder chip will encode / decode between analog audio and the digital voice mode you select. The compact size and features are ideal for travel. Most travelers lug their laptop with them when they travel anyway, and this small USB stick will allow operation on the digital voice mode of choice without also lugging one or more HT's. I purchased this from Wireless Holdings in Feb. 2017 for $238. Wireless Holdings has since discontinued this model. I have lightly used this and it is in perfect operating conditions. The Windows desktop software is a free download from http://wirelesshold.com/ Asking $175 shipped to you via USPS. Please email me with any questions.
