Frequently asked questions
What are the openSPOT4 and openSPOT4 Pro good for?
Let’s say you live in Budapest, and talk to your friends on the local DMR repeater HG5RUC, which is linked to talkgroup ID 216 (TG216) on the BrandMeister network.
If you travel around the world, where you can’t reach the repeater HG5RUC directly, you can still talk with your friends by using an openSPOT4 or openSPOT4 Pro and a DMR (or cross mode compatible) transceiver by connecting it to the same network and talkgroup which HG5RUC uses (TG216, BM). If you speak with your transceiver on the openSPOT4 or openSPOT4 Pro’s frequency, it will route your call to TG216, and HG5RUC will transmit your signals all around Budapest, so your friends will be able to hear and talk to you.
If you don’t have local repeater coverage, the openSPOT4 and openSPOT4 Pro can link you to supported digital networks all around the world. You can talk to people living on the other side of the world very easily.
What if I already have local repeater coverage?
If you do have local repeater coverage, you can still make use of an openSPOT4 or openSPOT4 Pro to avoid interrupting local repeater traffic. You can reach any reflector or talkgroup with it, so you don’t have to disconnect the local repeater and disturb other local users.
What makes the openSPOT4 and the openSPOT4 Pro way better than any hotspot currently on the market?
Currently the openSPOT4 and the openSPOT4 Pro are the only hotspots on the market which are customly designed as a dedicated hardware unit for standalone operation. They do not need a computer, a Raspberry Pi®, an Arduino® board, SD card or any other hardware to operate. They don’t need slow desktop PC software or drivers to install. No Linux knowledge is needed at all. They have a built-in battery and the openSPOT4 Pro supports hardware audio transcoding for the best voice quality.
The openSPOT4 and the openSPOT4 Pro were designed by hardware and embedded software professionals, who are also amateur radio enthusiasts. Its PCB, hardware components and case are very high quality, meet industrial standards and were chosen with practicality and durability in mind. We offer 2 year warranty*** with official support in email and on our community forums.
The openSPOT4 and the openSPOT4 Pro are not MMDVM® clones, they have nothing to do with MMDVM® or Pi-Star, and they are not a Raspberry Pi® wired with a bunch of PCBs in a case (or without a case…).
Using the devices are extremely easy. You can change every setting by opening the built-in web interface with a web browser. You can also use the Quick Setup feature to easily connect the openSPOT4 and the openSPOT4 Pro to a digital network like BrandMeister. Opening the web interface is rarely needed, as you can switch talkgroups, reflectors, and even pre-saved configuration profiles by using your transceiver.
Even the first time setup is very easy. If no Wi-Fi networks are configured, then the openSPOT4 and the openSPOT4 Pro appear as a Wi-Fi network access point on your phone/tablet/PC called “openSPOT4 AP”. Connect to this network, and a connection wizard helps you to connect the openSPOT4 and the openSPOT4 Pro to the available Wi-Fi networks.
Is it available as a kit or does it come preassembled?
The openSPOT4 and the openSPOT4 Pro are ready to use products in a box with all the needed accessories like any other product you can buy from the store shelves in your local electronic department store.
What about warranty and support?
We offer 2 year warranty*** with official support in email and on our community forums. We respond to all emails very quickly. There is a detailed user manual available here. We also have a Facebook page, and a Twitter channel with the latest news.
*** The battery and the USB-C charger cable have only one year long warranty period (70% battery end of warranty capacity).
How do you ship the unit?
We ship with FedEx with tracking. Orders of products in stock are shipped with delivery times of usually 2-5 days even to the most remote parts of the world. You’ll receive your order’s tracking number in an automatic email when the courier service picks up the package.

What happens if I move between multiple Wi-Fi networks?
The openSPOT4 and the openSPOT4 Pro automatically reconnect if the connection is dropped. You can set up multiple Wi-Fi networks to connect to, so it’s very easy to set it up for your home, vehicle, and work Wi-Fi networks. The device will automatically connect if one of the configured Wi-Fi networks become available.
Can two or more openSPOT4 or openSPOT4 Pros linked together?
Two openSPOT4 or openSPOT4 Pros can be linked together directly without any servers or network infrastructure. Interconnecting two digital radio sites can be easily done this way. You can also create your own private radio network by using our open source server application called SharkRF IP Connector Protocol Server. Multiple openSPOTs can connect to this server, it handles all radio modes, even supports cross mode operation. It also has a nice dashboard.
What is cross mode operation?
For example, the openSPOT4 can convert your DMR radio’s transmission to a System Fusion® network, and when someone talks on the System Fusion® network, you’ll be able to hear it on your DMR radio. This cross mode operation is extremely easy to set up. You can find the list of supported cross modes in the user manual here.
Are there any plans for a VHF version?
The openSPOT4 and the openSPOT4 Pro have a built-in antenna for the UHF band. Currently we don’t plan to ship a VHF (or dual band) version of the product.
The web interface has light and dark themes
Are there any plans for a DMR duplex (dual timeslot) version?
Currently we don’t plan to ship a DMR duplex version of the product.
Why doesn’t the openSPOT4 and the openSPOT4 Pro have a display?
You already have a display on your phone/tablet/computer and also probably on your transceiver which all can be used to interact with the openSPOT4 and the openSPOT4 Pro. You can change all settings using the web interface, and also using your transceiver with the help of a unique feature called configuration profiles.
Does cross mode work with D-STAR®?
In case you use the openSPOT4 Pro, then yes! D-STAR® uses an older codec which is incompatible with the newer one used by DMR/System Fusion®/etc., but the openSPOT4 Pro has built-in transcoding hardware, and it supports cross mode operation with D-STAR® radios/networks. The list of openSPOT4 and openSPOT4 Pro cross modes can be found here.
Will there be support for connecting to Ethernet networks?
You can connect the openSPOT4 and the openSPOT4 Pro to an Ethernet network using a Wi-Fi AP/router device.
Which Wi-Fi band is supported?
The openSPOT4 and the openSPOT4 Pro works on 2.4GHz Wi-Fi channels.
Can I use the openSPOT4 and the openSPOT4 continuously plugged into the USB power supply?
Yes! There’s even a setting which you can activate and then the openSPOT4 and the openSPOT4 Pro will turn on if there is external power available, and turn off if the external power supply is disconnected. This is very useful if you want the device to automatically turn on and off if you use it in a vehicle for example.
What’s the difference between the openSPOT4, the openSPOT4 Pro and previous versions?
The openSPOT4 is a whole new device with the latest technology improvements, built-in battery, beeper, Wi-Fi support, USB-C high tolerance power supply with fast charge support, built-in Wi-Fi and UHF antenna, a 0.5ppm TCXO with factory calibration for very low BER. The openSPOT4 Pro extends the feature set of the openSPOT4 with built-in voice transcoding hardware.
Most of the software components were redesigned to make the whole device extreme fast, future-proof, and use very little power. We’ve added new radio modes and network protocols since the openSPOT1. The web interface is redesigned and now use WebSockets technology which means extreme low latency and a whole lot of new realtime features.
Will there be an Android/iPhone app?
sharkrf.link is available as an application, but it is optional, as the openSPOT4 and the openSPOT4 Pro can be configured using its web interface. You can open it in any supported browser even on your phone.
Can I use multiple openSPOTs on the same network?
Yes! Make sure each device’s name is unique so you’ll be able to open each one’s web interface by their unique device names. You can change the device name at the Network Settings on the web interface.
