Why Hotspot

Why a hotspot ???


I don't know anything about these or why I would want one though.
ANSWER ::
I understand as I did receive a few emails with questions regarding the unit. In a previous article (the DV4mini review) I did explained in the introduction the purposed of a digital hotspot. Maybe I should have used is again. You can find the complete article on my personal website in the publication page. Below you will find part the introduction text of this review. Hope this help.



"More and more modulation protocols from different vendors are now available for the ham community, including D-STAR, DMR, and C4FM (Yaesu’s System Fusion). In the ham digital world, a reflector is a server connected to the Internet that acts as a virtual repeater. Digital hotspots provide the ability for amateurs to connect to those Internet reflectors from their digital transceivers. Hotspots contain a low-power transmitter and receiver for amateur frequencies, and plug into a computer connected to the Internet. "

SharkRF IP Connector Protocol server

SharkRF IP Connector Protocol server

This daemon can be used to create your own private radio network using SharkRF devices like openSPOT, or your own custom software/hardware, as the SharkRF IP Connector Protocol is open source.

Simply it's like a TAC310 off of the DMR network. A standalone talkgroup.

All connected and logged in clients receive the data you send to the server.

The below link will take you there if you need a good place to start. This tutorial is written as part two, picking up directly where part one left off.

SharkRF on DMR setup

The Openspot first with the supplied network cable (it can also be used another) to connect to the Internet router. Then connect the power supply to the openspot and then plug the power supply into the socket. The Openspot now starts.

After 1 minute, the Openspot is ready for operation.

Since no screen can be connected to the Openspot, all settings are set via the Internet browser. To do this, go to http://192.168.1.128/openspot.html_gz#login. The digits 192.168.1.128 are to be replaced by the IP address, which the Openspot has in its own network.



The password is entered after the call. The default password is: openspot



Click on "Connectors" at the top of the blue bar.



Click on "Advanced mode" in the blue bar.

Now select "Homebrew / MMDVM" under Connectors and click on the blue field "Switch to selected". The question, which appears please answer with "CHANGE MODEM MODE".

With SharkRF openSPOT you do not need a computer or Rasperry PI. Everything is already integrated in the blue box so that DMR(digital mobile radio) = Brandmeister / DMRplus / DMR-MARC or FUSION or DStar operation can be started immediately after the one-time necessary settings (capturing the own DMR ID, etc.).

The openSPOT requires the following hardware for operation: 
• openSPOT 
• Internet connection via Ethernet cable (no WLAN!)

The openSPOT works with a simplex frequency, which you can choose by yourself. It is available as a 70 cm version.

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

SharkRF openSPOT -  https://www.sharkrf.com/products/openspot/manual/

– 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).

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.

Review - SharkRF openSPOT

Review - SharkRF openSPOT

OK, so what is a hotspot?

A hotspot an interface that allows you to connect to a digital network directly without the need of an actual repeater. There are several variations of hotspots available. Some may require your PC or Raspberry Pi interface, but the SharkRF openSPOT is a small stand alone IP gateway that connects directly to your internet router via the Ethernet connection. No other equipment required.

The openSPOT was developed by two hams that not only understand what hams want, need, and enjoy, but know how to make it work with minimal setup. With features not found in other hotspots, the bottom line is, they did it right.

openspot01So, here's my take on openSPOT.

Private Calls between Two Openspot users

Private Calls between Two Openspot users

Can the Openspot be used to place a private call between two Openspot users? I have tried with no success so if it can be done, please explain. I have tried in local mode and when connected to a talkgroup that both stations were linked to.

Basic openSPOT setup


You need to set up a simplex channel in your radio with same RX and TX frequencies. You need to set the channel's TX contact to the talkgroup ID you want to talk to.

You'll need to create an RX group list also, put TG9 in the list, and assign that list to your simplex channel. openSPOT transmits voice announcements on TG9, so this way you'll be able to hear them.

SharkRF openspot as a Full duplex DMR repeater?

SharkRF openspot as a Full duplex DMR repeater?

I am mostly interested whether it will be possible to use the device as a full duplex DMR repeater even if only on local.

More then 20mW RF would also be terrific.

I am also curious if it is a small repeater or just another DV4mini. I do not need more than 20mW (actually, I think I will set it up on one of the european LPD 70cm channels and those are limited to 10mW).

[openSPOT] Is shark rf going to add wifi?

According to Norbert on the SharkRF team, "It will be available sometime later this year. We don't know any time frame yet".

Sorry to be impatient, but it has been nearly 3 months since the last update on an internal WiFi version of the Open Spot. I will definitely buy the WiFi version as soon as it is available!! Can you please give us an update. THANKS.

It just works. Period.

I've got a DVMega, DV4mini, DV4home, and now the OpenSPOT.
Out of all 4 devices, the OpenSPOT is the most stable and just works all the time.
The DVMega is good, but lately the Raspberry Pi seems to lose connection with the DVMega board modem forcing me to shut it down and power-cycle it.
The DV4mini...well, I think we all know the horror stories with that one.
The DV4home is also an unmitigated disaster. Google "dv4home review" for more info on that one.

But SharkRF has come up with a simple, small device that just plain works and I've been running it non-stop for over a week now with no issues.

SharkRF OpenSPOT

The SharkRF OpenSPOT is a stand alone easy to use digital hotspot for amateur radio operators. It’s support various digital modes like, D-Star, DMR and C4FM. This unit as an integrated web interface, no Linux and no Windows to managed. Everything is integrated in this very high quality little box. It also supports cross mode between DMR and C4FM (DN), you can do C4FM with your favorite DMR radio or you can do DMR with your favorite C4FM radio, this will help saving your precious radio money.

FYI: There’s no AMBE chip in openSPOT. Cross mode works by recalculating the FEC used in DMR and C4FM. The AMBE data is not touched, as it is the same in C4FM/DN mode as in DMR.
I received the unit in the beginning of August 2016, I’ve been using it ever since. Shark RF provides frequent software upgrade which improved the performance of the OpenSPOT every time. Beside the excellent and easy to use web base interface, it just looks nice. The physical box itself is very well built and I can feel the quality of the unit.
The OpenSPOT stay still on a table since it’s pretty heavy considering its size, no problem holding the network cable (cat. 5).

SharkRF IP Connector Protocol server

SharkRF IP Connector Protocol server
https://github.com/sharkrf/srf-ip-conn

This is the protocol used by SharkRF openSPOT's UDP API to allow 3rd party developers to create their own applications which communicate using openSPOT.

The protocol is designed for simplicity: strings are closed with zeroes, and packets have redundant fields. For example: call info can be extracted from raw DMR frames, but the protocol includes them in the packets separately, so 3rd party developers don't need to deal with call tracking.

Shark RF Openspot Review

I've got a DVMega, DV4mini, DV4home, and now the OpenSPOT.

Out of all 4 devices, the OpenSPOT is the most stable and just works all the time.
The DVMega is good, but lately the Raspberry Pi seems to lose connection with the DVMega board modem forcing me to shut it down and power-cycle it.

The DV4mini...well, I think we all know the horror stories with that one.
The DV4home is also an unmitigated disaster. Google "dv4home review" for more info on that one.

But SharkRF has come up with a simple, small device that just plain works and I've been running it non-stop for over a week now with no issues.

DMR and DSTAR audio feedback reports are that the audio is clear with no packet loss.
From what I hear, the C4FM users are also having no issues with it but I have yet to try that mode. It just does so much I haven't enough time to try out everything it can do.

Add to that they've released a complete set of APIs to remotely control the device for anyone who wants to build their own web-based or stand-alone app and they're light years ahead of the amateur radio digital hotspot competition with maybe the exception of the bluetooth-connected DVMega hotspots out there since the SharkRF OpenSPOT doesn't currently do bluetooth or wifi connections.

But for at home or hotel stays (with appropriate travel wifi bridge device) it really can't be beat


SharkRF openSPOT DMR ID for C4FM

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.

SharkRF Openspot Mobile Setup

SharkRF Openspot Mobile Setup

A quick look at my mobile SharkRF Openspot setup which includes the use of a TP-LINK TL-WR802N router. The router connects to the internet wirelessly via my 4G mobile phone hotspot. The Openspot can be configured using my tablet which is also connected to the same mobile hotspot.

The devices can all be powered either by a mobile battery pack or through my car's cigar lighter. I use an FTM 100 in the car with a Bluetooth headset to connect via RF to the Openspot.

The Openspot can be configured to connect to FCS or YSF reflectors as well as having the ability to link C4FM through to DMR.

For C4FM users I recommend you try connecting to FCS001/55 which (at the time of publishing) is linked through to the CQ-UK WIRES-X room.


Review SharkRF openSPOT

Hotspots were not developed to replace repeaters, but rather to supplement them. In areas where there is No repeater, a hotspot allows the user to connect directly to a digital network via the internet. In areas of Heavy repeater use, a hotspot allows the user to access the network without competing for an available time slot.

If your local repeater gives you access to a network such as DMR-MARC, an openSPOT can give access to networks such as Brandmeister. You will now have access to the best of both worlds.
Summary

DMR repeaters are being placed in service daily, but currently there are only around 800 repeaters in the US. As for me, I am 25 miles away from my two nearest repeaters and require an outside antenna to reliably use them (and I’m one of the lucky ones). In some areas of the country, digital repeaters don’t exist.

The solution quickly became obvious. To enjoy the freedom of a handheld, I needed the help of a hotspot. After listening to several configurations over the past several months, I am convinced daily that I definitely made the right decision with an openSPOT, with everything I need condensed into one small package.

What's So Special?? Shark RF Openspot Review

What's So Special?? Shark RF Openspot Review

This week I'm reviewing the Openspot by Shark RF. No images to hunt down, It runs D-Star, DMR & Fusion all in one box.


Shark RF Openspot Review


Shark RF Openspot Review

First, let me say that I have been engaged in digital voice radio since the early 2000's and I have had experience with Project-25, D-Star, NXDN, DMR, and C4FM and I have owned and built several hotspots over the past ten or so years; to-date, I have not found a better product for use with digital voice. As of this writing on 09/21/2016, firmware version 0056, the device supports three modes; DMR, D-Star, and C4FM. One unique feature of this product is the ability to transcode from DMR to C4FM and C4FM to DMR, meaning you only need one radio to work both modes. No need to waste your money on purchasing crappy Yaesu hardware that is plagued with numerous interface and firmware issues. If you have a DMR radio, just setup the transcode mode and talk to your buddies on C4FM; though there aren't many there as the bulk of the users are in the DMR and D-Star worlds. For the money, this is an excellent device, that is quality built, has a very clean web interface for control and the firmware updates couldn't be any easier to perform, even for novice computers users. If you are new to DMR or D-Star, this is the device for you; don't waste your money on the DV4mini or ANY product from Wireless Holdings, they are plagued with software and firmware issues, lack support, and sound just awful on the network with VERY few exceptions. This device powers up and works and experienced users can even tweak the advanced settings to perfect their audio and operating conditions. This will be the best $225 you'll ever spend exploring digital voice operations on amateur radio. If you want to hear live audio from it or just ask questions about this device, give me a call either on DMR via "USA Nationwide" talkgroup or on "D-Star Reflector 030C" as I am always monitoring both. Get yourself a Shark RF OpenSPOT, you won't be disappointed... As for the DV4mini, if you have one, please stop polluting the DMR talkgroups and toss that POS in the garbage where it belongs so we can all enjoy the clean, crisp-clear audio of DMR again!

openSPOT Setup and Interface

openSPOT Setup and Interface

To set up the openSPOT, I connected it to the USB power source and my WiFi router using the supplied Ethernet cable. The openSPOT has two internal micro-controllers, designed to use a web based interface. Once connected to my WiFi router, the openSPOT was accessed by simply logging into //openspot.local. I didn’t need to load any additional software or drivers. Everything is self contained.

At that point, all that was necessary was to enter:
– The operating mode (DMR, C4FM, D-Star)
– My callsign
– My DMR ID (available from DMR-MARC)
– The desired server
– The input and output frequency of my handheld
Note: The openSPOT allows you to select two different frequencies if desired.
After that, a 30 second calibration, and I was on the air.
The LEDs give a clear status indication during operation.

Once configured, time slot, trunk group, etc. information is controlled by your handheld. You set it, and forget it.
