Digital Mobile Radio DMR MMDVM Hotspot Jumbo Spot

K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    Cant get the display to work on the Jumbo spot ? I am connected to wifi and running.

    Hi Dave,

    All great questions. Here is my post and video on the codeplug. This is not for your radio, but should give you some information and answer some questions.

    I used 446.500 MHz and it is designated as Digital in my codeplug and you’ll see where to put TS2 (Slot: Slot2) in your codeplug.

    I hope this helps. Best 73!

    Hi, Rich. N2TRY (Dave) here. Great site and good beginner information. I have a n00b question for you (or anyone else in the thread). I recently purchased an Anytone AT-D878UV (nice little rig).

    My question: How do I program the hotspot frequency into the code-plug? (Should this be an Analog or Digital simplex frequency)? If it’s digital should this be Slot 1 or 2? I notice in the videos (both here and elsewhere) where it’s observed TS1 is disabled and TS2 is enabled (and this is critical I understand). Is the TS2 on the pi-star set by default or in the defaults? Maybe I missed that.

    Kind regards & 73’s

    Hi Eugene,

    Yes I remember and nice to hear from you again. I hope your trip went well.

    I am still perfecting the KX2 antennas, hi hi.

    I think you are referring to programming a code plug for his radio. Those are very popular radios and there is probably a sample of one he can look at on YouTube or Facebook.

    Chris knows a lot about those and he is on YT: https://youtu.be/KmSIymg8i7o

      I have a question about the sported frequencies. Would i be able to transmit VHF into it if i had a VHF antenna for it? I would be using it for P25.

        Hi William,

        Nice to hear from you.

        Would you be able to use a VHF frequency instead of the UHF? Good question! I have not seen anyone doing that. I see that it says it will work either UHF or VHF. (The MMDVM hotspot support module can work with UHF or VHF(VHF is not the main band)).

        I suppose it is worth a try. Thanks for the question and thank you for commenting here.

    Rich,
    Got a question. Just visited a friend today who has a JumboSpot, seems to be programmed but he doesn’t know how to get the BM Jumbo Spot data programmed into his computer and copied to his newly-purchased TYT MD-380.
    Suggestions?
    BTW we met in South Dakota at a campground in Pierre last July. Exchanged photos, etc.

    BTW I have a Nano-Spot, and my entries to the computer/MD-380 go like “NS TAC310,” etc.

    Hi Don,
    Nice to hear from you and thank you for commenting here. I don’t believe so, I did not have to and I have not heard anything like that. If you can set it up as a temporary DMZ that would answer your question. That’s usually pretty easy to do in the router. I would think it’s just a configuration error somewhere and look at the Configuration I have again to see if you have a typo in there or something not configured properly. Use the same server that I show in the video and configuration photos.
    If you have an HD one I also have a video on it.
    By the way I don’t think I got the parrot to work on mine. I am not sure why, but since it is working otherwise I didn’t bother with it.

    Can there be any issues between the DMR hotspot and the server that it connects to? I can send all day but have only heard one gentleman testing something. I have tried on parrot and I see the hot spot responding and then listening. Then I hear no reply. I also have another DMR radio and I have sent on that and do not hear any traffic on the hot spot. Firewall issue on the router? Do I need to open firewall ports on the router or forwarding ports on the router?

    Great post. I need help in understanding how I would configure the Radio to transmit to the Jumbo Spot.

    Hi Lee,

    Nice to hear from you and thank you for commenting here.

    I am not really familiar with the 7100. It looks like it has D-Star though.

    The pi-star software in the Jumbo Spot has D-Star. I would do some searching and see how it works.

    That’s very interesting about the 7100 and thank you again.

    I have a Icom7100 which has DMR capability. That’s one of the reasons I bought it, but sadly, later found I cannot hit any of the DMR capable repeaters in my area. Too far away I guess. Looks to me like the Jumbo Spot should work with the 7100 like the handheld you described. Am I correct in my assumption?

    Right now, with the FCC crackdown on chinese DMR Radios, it’s hard to know which ones are compliant and which ones are not. I believe your Ailunce is on the FCC blacklist now, but I see it’s still being sold on Amazon. I guess I’ll wait and see which ones get put on the compliance list later then decide if I want to give DMR a try.

    • K0PIR says:

      Hi John,

      I know there’s been discussion about that and we even discussed it a a ham club meeting one evening but we didn’t get too far with it. I think the majority of us own one of the Chinese radios.

      I don’t know much about these things but, looking at my Ailunce HD1 I see it has a FCC ID label. I know they are selling them in the United States.

      These are good things to be aware of especially since they transmit out of band. Honestly I just wish they would have taken precautions like other manufacturers.

      Thanks again John best 73!

    Thanks for the article Rich. In my opinion, using the Jumbo Spot with your transceiver makes it a VOIP hybrid. Not completely VOIP since you are using a handheld transceiver, but still VOIP since it is transmitted digitally over the internet.

    • K0PIR says:

      Hi John,
      Nice to hear from you and that’s what I think. I still see it as ham radio because I’m still using my call sign and I’m using a radio. It just goes out over the Internet instead of the airwaves. In all honestly I like the airwaves better Lol

    Hi Rich, AE/KE0OHH here. Is there a difference between a Jumbo Hot Spot and a WiFi Hot Spot? I have a Hot Spot on my laptop that my phone connects through. I live in a very remote county in SW Colorado, with one repeater, but it is reachable only in a restricted region. We have no TV or radio reception, and the cable company pulled out 6 years ago. BUT, I have high speed fiber and a 10 meg. connection. How do you feel about DIY Raspberry Hot Spots? 73

    • K0PIR says:

      Hi Robert,
      Thanks for commenting here.
      Yes there is a difference. Not to confuse things, but to keep it simple, I usually think of a Wi-Fi hotspot as a device inside a restaurant or café that I can connect too with my laptop and connect to the Internet. That’s a easy way of looking at it.
      Most Internet service providers provide a modem with a wireless router and that’s what I am using to connect my jumbo spot too. The jumbo spot does not have a wired connection, only wireless.
      I have not used the raspberry pi as a hotspot, but I think I’ve seen them. I’m not sure how easy it will be to configure, but I bet there’s a lot of help out there.

      Thanks again and hope to hear you on, 73!
