MMDVM Hotspot Board + Aluminium Case: Ultimate Support for UHF VHF, P25 DMR YSF DSTAR NXDN POCSAG on Raspberry Pi-Zero W, Pi 3 Review

This kit is used to create a digital ham radio voice access point. To complete the build you will also need to purchase a Raspberry Pi Zero board (preferably with the headers already installed) and a micro SD card. My kit had all the parts needed to complete the build in under half an hour and when powered on it worked the first time. I would like to warn you that the written instructions that come with this kit are pretty much useless, but there are plenty of good YouTube videos to guide you…

Will not transmit or receive on FM. I've been a radio engineer for 4 decades. I have lab equipment to test this. Does not work on FM. It works great on UHF and 900 ham radio bands. I have an NXDN VHF and this is a disappointment as I bought two. Email was answered quickly but still awaiting resolution to make it work on VHF. If not I will be returning them via Amazon shortly. The seller responded fairly quickly and identified the problem. He sends me a new board from the factory that is updated

I bought this and added it to my Raspberry Pi Zero + Wireless. The instructions aren't very clear, but once you turn it on, you'll need to use a computer with Wi-Fi (not your desktop if it doesn't have Wi-Fi) and log into the device at the given IP address. You can then configure for your network. I forgot that if you are using a "hidden" network, you need to make the network visible so the Pi can see it. Configuration was easy, although it did require some google searches and reading a few…

An amateur friend persuaded me to buy a similar (same?) product in another store and save 40% on the cost, but it came directly from China and had delivery 4 -6 weeks. I bought it and am glad I did as I received it in two days and my DMR radio was on air the next day. Sure, I'd rather pay around $43, but price isn't everything. As another buyer noted, there are no instructions, but they are not needed. A licensed radio operator is expected to have some skill and knowledge of the kit before…

I was also a little concerned at first about the lack of offset data and device type information (it's actually printed on the board) , but as I continued with my project I found that the offset was actually zero and with 3B+ I had to use the latest PiStar beta and get a little creative with the editing. I reached out to SHY and the response was almost immediate and very informative. Anyone can sell parts. Customer service matters. I love it so much I will be buying another one soon and using…

I have mine to play with while I recover from disc replacement surgery. I figured it would take some time to get everything set up and give me something to do for a few weeks while I recover. Not correct. It took maybe 3 hours for the network to work properly. I made contacts that first evening, including in the UK (from Alabama). I turned it off, assuming it would have to rest in the morning. Wrong again. I turned it on and it just started working. I did this in my car using my phone as a…
