Digital Voice Modem for MMDVM Hotspot Spot Radio Support C4FM YSF NXDN DSTAR P25 DMR

No issues at all, very easy setup (provided you have a basic understanding of pi-star and the radio you are using), working perfectly at home and mobile tethering through my phone. Did not need to adjust TX or RX offsets. If you do not have any experience with pi-star setup, please do your research ahead of time, it isn't hard, but it can be a bit confusing your first time. I have helped several people sort things out, and it seems it is most often a setup issue with THE RADIO.... not the MMDVM

Great product, worked right out of the box, and was delivered on time. Once I validated it was working. I upgraded the pi-star software to beta v.4rc3, on a new 4GB Micro SD card. Did the base configuration provided in the packaging , and once again was up and running. Be sure to look into the fine tuning of the radio RFOffset/TXOffset, some good YouTube videos out there.Have Fun and 73, KE8LNP

Was very hard to get going when we started, chip was replaced and new chip loaded with new pi-star. It did start up and program properly, ran for few days and then started to become intermittent on working. Have since then have made 3 more sd cards and it works for a short time on each card and then eventually stops working. I have step up a few for friends and they all keep going, mine has a problem. Will see what supplier will do to fix the problem.

Great instructions included. Even got a followup email asking if i needed technical support. Comes with an example config so you can just edit. Plenty of online resources and youtube videos to help you out. Well made. Good value.

Although the product appeared to be well made. I was never able to get it to work. In addition, the instructions that came with the product were not clear.After reading some other reviews on this same product it appears that there are some issues with this product. Either it works or it does not.
