How do I change my call sign in my ClearNode ?
Your call sign is used in our authentication system. In short, you can’t make the change on your node yourself – you have to let us know and we make the change on our end. We usually get to the change done quickly once requested – we will need your node online and idle to make the change.
Why isn’t my cooling fan running ?
On the new ClearNode V3 based on the Pi4B, we have included a cooling fan. However, the fan only runs if the CPU temperature is above 60 deg C. This is so we don’t waste power driving it when it’s not needed – since many folks run their ClearNodes on USB Battery Packs. Be careful not to obstruct the vents on top of the node so air can flow freely. See below for our notes on node temperatures.
What does this setting do ?
A lot of the settings in the various setup screens are associated with a description to help you identify its purpose. Long press on the title of the setting and a popup will appear with some notes on what the setting is for.
Can I use a different USB Power Supply ?
We’d rather you didn’t – we go to some length to source a quality PSU for ClearNode. The compact form factor of ClearNode can be susceptible to noisy switching power supplies. Aside from noise, a lot of the cheaper PSUs have unstable voltage and/or can’t supply the current ClearNode needs. ClearNode needs a stable 5.2 V and at least 2.5 amps. Keep your eye on that red LED on the edge of the Raspberry Pi PCB – if that’s blinking, ClearNode is experiencing an under-volt condition – that’s not a good thing – in particular you may corrupt the SD Card.
Can I power ClearNode off my vehicle USB outlet ?
In general we discourage it. There is so much variance in the quality of vehicle USB power that it’s our assessment is that it ends up being a threat to the proper functioning of your ClearNode.
My personal preference is to power my ClearNode from a 5V USB PowerBank battery. ClearNode will run for 4 or 5 hours on a 10,000 mAhr battery. Such batteries are quite inexpensive these days. But take care when you purchase – read the fine print. ClearNode needs at least 2.5 amps at 5.2V to function properly. Beware the PowerBank manufacturer that claims 4 amps capacity but doesn’t mention that it is shared between 2 ports and the max on each port is 2 amps.
I’m struggling with connecting my ClearNode to WiFi, or switching it between WiFi Networks
We’ve put together an overview page on managing WiFi on your ClearNode, it’s well worth a read – especially for you road warriors that often have to switch between your home/office WiFi and your mobile hotspot – MANAGING WIFI.
DTMF commands are un-reliable or don’t work at all, are they supported ?
DTMF commands are supported and a default set has been deployed in rpt.conf – contact us directly for the list – we don’t publish them or make them public.
Difficulty with DTMF is nearly always a function of mismatched deviation levels between your HT and the decoder in Asterisk. Turn on “Audio Analysis” in the node setup pages and observe the audio levels in the “Adjust USB Audio Gain for VOIP” section (see AUDIO TUNING). You’ll need at least 5 seconds of continuous PTT with DTMF tones for ClearNode to analyze the audio. If there are red indications in the bar graphs, either high or low, you either need to adjust the deviation in your HT or compensate for your HT in the “Adjust USB Audio Gain for VOIP” section – lower or raise “To VOIP (rxmixerset)”.
My ClearNode runs warm, is that OK ?
We provide the Raspberry Pi’s CPU temperature in the Node Detail screen of the mobile apps. (You can choose deg C or deg F in the settings screen). This is not the enclosure temperature – it is the temperature that the CPU is reporting – we treat it as proxy for the overall temperature of the node.
We’ve reviewed the specification for the Broadcom CPU and we’re not sure why people are quite so paranoid about temperature. So here’s our take on it:
- < 65 deg C (150 deg F) – green, no worries
- 66 deg C to 75 deg C (170 deg F) – yellow, particularly at the higher range, think about cooling, keep it out of direct sunlight, away from other equipment that’s generating heat, maybe even a fan
- > 75 deg C (170 deg F) – red, definitely take action, at 80 deg C (175 deg F) the software on ClearNode will issue a shutdown to the operating system to protect the device.
Should I keep my ClearNode powered ?
Your ClearNode uses very little power, if you keep it powered and connected to the Internet all the time it’s registration with the AllStar servers will always be fresh so you can instantly connect to remote nodes. If you power it down the registration will expire and will not be active again until you power it up again. Once powered and connected, it can take as much as 10 minutes before your registration has propagated through all the registration servers. During that latency you may not be able to connect to some nodes.
Reboot your node once a week to clear out temporary and log files and give the operating system a fresh start. The reboot will also trigger the node to check for software updates which will be installed automatically if that option is selected in your node setup.
How do I disconnect a connection !??!
Short story – navigate to the Node Details screen and: in iOS, swipe left on the connection and tap “Disconnect”, in Android, long-press the connection and select “Disconnect” from the popup.
How do I allow people to connect to my AllStar node ?
By default your WiFi router or Internet Access Device blocks IN-bound connections to your home/office network and your Internet enabled devices. In general all OUT-bound connections from your devices to the public Internet are allowed. So ClearNode and other AllStar nodes can connect OUT-bound by default. To allow folks to connect IN-bound you must create a Port Forwarding rule for UDP Port 4569 (the default port, your port may vary) to the IP address of your ClearNode. Most home/office Internet Access devices have instructions along with the username and password either printed on the case of the device or in the documentation that came with it. Generally you use your web browser on a computer inside your home network to connect to the device. Once you’re logged in, look for the “Advanced” section that refers to “Port Forwarding”.
I have Echolink configured on my ClearNode, it connects to other nodes but no traffic passes – what’s wrong ?
Unlike AllStar, Echolink requires port forwarding for both IN-bound and OUT-bound connections – see above, but you need 2 ports – one for UDP Port 5198 and one for 5199. Some routers allow forwarding a range of ports so input 5198-5199 UDP forwarded to the IP address of your ClearNode. From time to time your router may assign a different IP address to your ClearNode essentially invalidating the port forwarding rules you created. Most modern WiFi routers provide a DHCP service that allows setting up a “Static DHCP Lease” that is tied to either the device’s MAC address (hardware ID of the WiFI or Ethernet connector) or the hostname – this will keep your IP address constant.
I’m an experienced Linux Op – can I SSH into my ClearNode ?
Yes – but there are caveats. ClearNode is based on the Raspberry Pi running the ARM variant or ArchLinux. We set the root user password to your ClearNode Key before shipping. When you receive your node, feel free to reset that password to whatever suits you. We keep the SSH port at the default – Port 22. If you decide to configure your node the legacy way by manually editing the various “.conf” files – be aware that if you subsequently use the ClearNode mobile app to change configuration – ClearNode will recreate the “.conf” files from templates – overwriting the edits you made at the command line. Get in touch – there are workarounds for particular needs. Or better still – tell what’s missing from the ClearNode mobile app and likely we’ll get it deployed.
Can I connect my ClearNode to my high-power repeater ?
ClearNode is intended as a personal, portable low power node. It has a built in 500 mW UHF (or VHF) transceiver – there are no connections for Spkr, Mic, COS, PTT. We do have a product specifically for controller repeater installations – ClearRPT.
If Node-Ventures LLC goes out of business is my ClearNode a “brick” ?
Absolutely not ! ClearNode is a standard AllStar node, currently based on the HamVoIP.org distribution and the SA818 transceiver. You can control it with DTMF commands, you can edit the various “.conf” files, and you can use the excellent configuration utilities created by the team at HamVoIP. Supermon is installed and configured by default and we test it before shipping to make sure all is well. The Digital Modes would be a little more complicated – apart from connecting to the 1999 bridge node via Supermon, you would have to use the DVSwitch scripts at the Linux command line to configure and connect/disconnect to digital endpoints. That is all independent of the added convenience and simplicity that the ClearNode Mobile Apps bring to node configuration and control.
