Note that on BrandMeister, DMO mode links the two timeslots together, so this setting is irrelevant.

– You can set the TDMA channel for data in DMO mode. DMO mode is enabled if the modem’s RX and TX frequencies match, or the modem is in DMR Hotspot mode. In this case, only one TDMA channel will be used for communication. Note that on BrandMeister, DMO mode links the two timeslots together, so this setting is irrelevant.


2 Static Talkgroups to different Time slots

In Brandmeister you can set multiple Static Talkgroups. On static talkgroups you don't need to link by pressing the PTT. So static Talkgroups can be add to a scanlist on your tranceiver.

if you have, for example, 2 static talkgroups set and you have a QSO on the first then it can be happening that on the second talkgroup another QSO wil start. This can disturb your QSO on the first Talkgroup since there is only one Time slot.

Is it possible to set the second Static Talkgroup to the second Time slot? I think this wil be a great feature but i don't know if this wil be possible in openspot.

DMR Hotspot from SharkRF

DMR Hotspot from SharkRF

A few years ago, I picked up some used MOTOTRBO gear to use on our local DMR repeater system (MOTOTRBO is Motorola’s version of DMR). Here in Colorado, the Rocky Mountain Ham Radio group has been instrumental in establishing a great network of DMR repeaters, a real asset for Colorado radio amateurs. See Rocky Mountain Ham Radio TRBO/DMR Network.  Worldwide, the DMR-MARC organization has created a robust network of MOTOTRBO repeaters in over 60 countries.

A more recent development is the establishment of the BrandMeister Network, which promotes more of a homebrew approach to DMR. This evening, the BrandMeister dashboard shows 634 industrial repeaters (commercial equipment), 263 homebrew repeaters and over 1300 hotspots of various types.  A variety of DMR hotspots are available, including the DV4mini. I’m not going try to list all of the hotspots available as I’m sure I’ll miss something.  The SharkRF openSPOT caught my attention because of this excellent review by John ‘Miklor’ K3NXU. Because of its popularity, the openSPOT is on backorder (price: 182.5 Euro).

Re-download the firmware file and load the flash firmware and complete, make sure you get the "success" file message at the end.

It was suggested by a fellow HAM that the solution is to wait for the acknowledgement full complete of the loading of the flash firmware "success" file

OpenSPOT Tp-Link nano router model # TL-WR702N Setup

I'm having an issue getting the Tp-Link nano router model # TL-WR702N to see my openspot device.
I've gone thru the instructions on router but I think I need someone to walk me thru the procedure on setting up the router correctly. I want to use this in my mobile with iPhone. I can get the iPhone to access the routers web interface but when I have the openspot connected to router I have red LED flashing on status trying to connect. I think I just may not have router set correctly.
Any help very appreciated.

Multiple DMR IDs on one OpenSpot radio

Can you use multiple DMR radio from different DMR IDs on one OpenSpot?

Yes. If you want, you can also lock an openSPOT to 3 separate DMR IDs/D-STAR/C4FM callsigns, but this is optional.

If you set the default DMR ID for C4FM calls to 0, then you must set the callsign on your Yaesu radio to your DMR ID, otherwise if openSPOT can't parse your callsign as a number, it will send your calls with source DMR ID 0. That's what the default DMR ID for C4FM calls setting is for.

D-STAR not linking to D-STAR servers

Information that may be helpful for obtaining a unique (club) callsign in the US can be found below:

However, a unique callsign for ircDDB may not be needed for your purpose(??). Below is a cut and pasted note from an article discussing callsign registration.

Note: Many of us, for callsign routing, moved on from G2 to using the ircDDB system. But some people did not like, when using ircDDB for callsign routing etc., to have to also register at ircddb.net. These people believe each country’s FCC equivalents have regulations about being licensed, and that is enough, and in any case, there is no way to stop people from breaking the law and using someone else’s registered callsign.

How to Link OpenSpot to a C4FM Repeater?

How to Link OpenSpot to a C4FM Repeater?

We have used a hotspot on our repeaters and found putting it in the repeater case worked for us.
Our repeaters are based around the Yaesu DR-1X.
We have planes to use the cross mode capability of the openSPOT in the future.
