Estink MMDVM Hotspot,Support PI-STAR, digital amateur mode DMR, D-STAR, P25 and YSF, with antenna + 8G TF card, suitable for Raspberry Pi,built-in WiFi

Product Information

I noticed after a while, that my BER percentage of my MMDVM_HS_Hat and Pi-Star setup was significantly higher than other users, at around 3.5%. I know from setting up GB7KH that getting this correct takes patience. I also happen to know that the design of the MMDVM_HS_Hat uses inexpensive TCXOs to provide frequency and timing references. As such, some calibration can do wonders for the BER on DMR. A lot of hotspots come with little screens on them. In the limited time I’ve had the Zumspot, I really don’t look at the screen at all so I didn’t include one as part of my build. A “high-powered” hotspot or repeater. Anything deployed, no matter the coverage, helps add to the infrastructure. Just be sure to advertise the repeater/node. Sharing is caring! This thread all started because I was totally confused having been out of amateur radio so long (as has Nigel my friend) but now have a d-star transceiver IC-9700 and Nigel an FT991a. The digital voice ham radio stuff is still taking some learning and at the same time things are developing all the time behind the scenes, versions of AMBE codec and linking etc are all a boggle. I will have to take a lot more time looking at your post and the links within it to follow what you are saying.

This MMDVM kit enables the different mode of digital walkie talkie communication with each other, it supports DMR, D-STAR, P25 A system like Brandmeister is particularly powerful, which is why it's become popular for DMR users. It is really a second generation approach to building and maintaining one of these voice infrastructures.Some GM950E:@BG7RLY TXInvert=0, RXInvert=0 , use sudo pistar-mmdvmcal test "B", A/M, you can find the true value. Most use RXInvert=1 A personal, low-power hotspot is a combination of hardware, firmware, and software that lets an amateur radio operator with an Internet connection link directly to digital voice (DV) systems around the world. With a transmitter power of around 10mW, a hotspot acts as a personal repeater so you can connect to a variety of digital radios and digital networks using an HT or mobile radio, including:

I’m using a CanaKit Raspberry Pi 3 B+. CanaKits are great but I wouldn’t recommend them for this project. I had to remove most of the case to fit the MMDVM board. My Motorola XPR 6580 was unable to decode anything and neither was DSD+. Frequency was not center stable and no amount of adjustments helped which may be the issue. (KD9KOO)Now there’s a new type of self-contained hotspot, the openSPOT. It has a tiny built-in computer and AMBE(Advanced Multi-Band Excitation) chip which supports cross modes. For example, you can talk with your D-STAR transceiver on DMR, and with your DMR transceiver on D-STAR networks. Through a series of bridges and gateways between these voice infrastructures, users of the different over the air digital technologies can communicate with each other. There are differences between how the private conversations and group conversations are structured ("Rooms" in YSF versus "TalkGroups" in DMR, for example) but techniques have emerged for getting them to work together.

I did this at first before I finally installed it in a nice clear case like it is today. A web interface that can be accessed from a smart phone or computer to control the node remotely with real-time activity.

That’s it. Radio setup is enough to have its own post. If I create a post for that I’ll update this post to include a link.
