- [La Crosse WX Beacons to APRS WX Packets](https://ioclarity.ca/la-crosse-wx-beacons-to-aprs-wx-packets/): I have a La Crosse weather station, which has several weather sensors that beacon on 915 MHZ. During COVID I took it upon myself to try to intercept the telemetry from these sensors, decode it, and then repackage and transmit the data as APRS packets on the RF Network. I had this working at that time, but it would fail whenever my pi rebooted. I have recently revisited this project and have a working setup. I will make sure to document this project and post a link to it in this post at a later date. The project used a […]
- [Naming your /dev/ttyUSBx devices on a Raspberry Pi](https://ioclarity.ca/naming-your-dev-ttyusbx-devices-on-a-raspberry-pi/): Don’t think I will post this anywhere but here in the blog section, as it is well documented, but I recently needed to name the /dev/ttyUSBx devices on one of my Pi’s. This was because on reboot, sometimes my ARPS TNC would get /dev/ttyUSB0, and other times my Icom 4100 Radio would get /dev/ttyUSB0. Rather than checking and re-writing my APRS and D-Star hotspot configurations at each boot, I found that I can create my own static names for these devices. First, create a file called /etc/udev/rules.d/99-usb-serial.rules file with the contents similar to this: I say similar, because really what […]
- [Raspberry Pi AMPRNet IPIP Gateway](https://ioclarity.ca/raspberry-pi-amprnet-gateway/): Last year I discovered AMPRNet, and how any Licensed Amateur Radio operator can have a set of public IP’s. In my spare time, I have been slowly tinkering with AMPRNet and I have recently had some success with creating a Raspberry Pi AMPRNet Gateway. I will post my configuration / how-to in the Amateur Radio section a bit later on over the Christmas break, but here are the highlights: Auto-update AMPRNet portal with local public IP when a change is detected. When this happens, the AMPRNet is inaccessible for about an hour while things refresh – thankfully it does not […]
- [Disconnecting and reconnecting Yubikey Nano in Windows without removal](https://ioclarity.ca/disconnecting-and-reconnecting-yubikey-nano-in-windows-without-removal/): I just added a reference document on how to disconnect and then reconnect a USB device (in my case a Yubikey nano) without actually removing the device from the computer. The documentation can be found here. Summary I have two GnuPG smart cards that I use to store GPG authentication keys on. One is a Yubikey nano, which I keep in my device most of the time, while the other is a Yubikey 5 NFC which I keep on my physical key ring. Often I need to use the GPG keys that are on my 5 NFC but GPG4Win seems […]
- [GnuPG SSH Authentication content added!](https://ioclarity.ca/security-stuff/): I have added two new pages, how exciting. Finally some content. The first page is pretty self explanatory. It is just my public keys for encryption, etc. For now only my public GnuPG key is there if anyone wants to send me encrypted email. I know, boring. But my other page is all able a fun little project I just finished. I wanted to use GnuPG keys to authenticate to my Raspberry Pi but I wanted to store my private keys on my Yubikey. Furthermore my client PC is a Windows 10PC using Putty and gpg4win. And after much frustration […]
- [My First Post](https://ioclarity.ca/my-first-post/): Today I have decided to make this website. Over the holidays I have been tinkering a lot with Amateur Radio (D-Star), Yubikeys, Linux and home networking. This resulted in a lot of time searching the depths of the internet to find the answers to some of the issues I faced. I have realized that I need to start documenting my hobbies. If my past is any indicator life will get in the way and it may be months or years before I come back to what I was doing. My initial plan was to document this information on my local […]

- [Intercepting, decoding, repackaging, and beaconing La Crosse WX Beacons as APRS WX packets](https://ioclarity.ca/intercepting-decoding-repackaging-and-beaconing-la-crosse-wx-beacons-as-aprs-wx-packets/): Build information coming soon. for now, check out the related blog post for a link to the code / description.
- [Building a Raspberry Pi AMPRNet IPIP Gateway](https://ioclarity.ca/building-a-raspberry-pi-amprnet-ipip-gateway/): Earlier this year I discovered AMPRNet, a large IP space on the internet reserved for Amateur Radio use. Intrigued, I decided to see how it all worked, so I set out to build my own AMPRNet IPIP Gateway on a Raspberry Pi to serve up my own /27 network space. I had some difficulty setting it up alongside my home network, so I documented how I built it hoping it will help others who are also interested. These instructions detail how I built my AMPRNet IPIP gateway, which includes all the routing, firewall (to protect itself along with the local […]
- [Disconnecting and reconnecting Yubikey Nano in Windows without removal](https://ioclarity.ca/disconnecting-and-reconnecting-yubikey-nano-in-windows-without-removal/): I have two GnuPG smart cards that I use to store GPG authentication keys on. One is a Yubikey nano, which I keep in my device most of the time, while the other is a Yubikey 5 NFC which I keep on my physical key ring. Often I need to use the GPG keys that are on my 5 NFC but GPG4Win seems to have a real hard time with multiple smart cards plugged into the computer at the same time. The problem I was having is that the Yubikey nano is really hard to remove from the PC (as […]
- [Adding existing GnuPG keys+Yubikey to new Mac client](https://ioclarity.ca/adding-existing-gnupg-keysyubikey-to-new-mac-client/): I originally generated my GnuPG keys on a secure windows client for SSH authentication and moved the private keys to my Yubikey. Recently I wanted to use another client to SSH to the SSH host and so I wanted to configure it using the same keys. Turns out it was super simple for a couple of reasons: I already have my GnuPG keys generated and stored on my Yubikey, and MacOS is was way easier to get working. IMPORTANT NOTE: This is not a step-by-step tutorial, it is a configuration guide and it assumes you have IT skills and know […]
- [GnuGP SSH Authentication with Yubikey and PuTTY](https://ioclarity.ca/gnugp-ssh-authentication-with-yubikey-and-putty/): This configuration documentation assumes that the client is a Windows 10 PC, with gpg4win installed and functional and the server is a Linux host running OpenSSH. I am sure that other versions and platforms will work with the same configuration. In my case I am using a Raspberry Pi with SSH enabled as the ‘Linux host’ and my Windows 10 Laptop as my ‘Windows 10 PC’ running PuTTY version. IMPORTANT NOTE: This is not a step-by-step tutorial, it is a configuration guide and it assumes you have IT skills. Also ignore the best practices that I am not following in […]

- [D-Star](https://ioclarity.ca/d-star/): I have been using D-Star since 2019(ish) and have fallen down the rabbit hole of possibilities of what I can do with it. My primary D-Star rig is a Kenwood D-74 HT, but I also have an ICOM 4100 mobile installed in one of my vehicles. Over the 2024 winter, I plan on documenting the following items as it relates to D-Star: I have also started to dabble in the world of Yaesu C4FM, and at some point I may add another section on this site related to it.
- [Amateur Radio](https://ioclarity.ca/amateur-radio/): Building a Raspberry Pi AMPRNet IPIP Gateway Instructions that detail how to build an AMPRNet IPIP gateway, which includes all the routing, firewall (to protect itself along with the local AMPRNet network), and a self-update script. I found this a very fun project, however it took me a while to accomplish with life getting in the way.
- [Security](https://ioclarity.ca/security/): Disconnecting and reconnecting Yubikey Nano in Windows without removal GPG4Win on Windows 10 (and other versions of windows) has some issues handling multiple smart-cards. I had a need to virtually eject the Yubikey nano and then reconnect it again when I was done with my other Yubikey. This documentation describes how I resolved this issue. GnuPG SSH Authentication with private key kept on Yubikey from Windows PC and PuTTY This was a fun little project. I wanted to use GnuPG keys to authenticate to my Raspberry Pi but I wanted to store my private keys on my Yubikey. The configuration […]

While the logical network largely remains the same, I have rebuilt the network using TP-Link Omada gear using a TP-Link OC controller, TP-Link Router, two TP-Link switches, and two TP-Link Access Points. NOTE: 2025-06-26 This information is outdated, and will be updated on a future modification. While the logical network largely remains the same, I have rebuilt the network using Ubiquity UniFi gear. Below you will find some information regarding the networking setup I am using. This is mostly for my reference, but I am posting […]

- [Home](https://ioclarity.ca/): Hi there. I often view various blogs and find reference documentation for work and my hobbies. Things like code snippets, troubleshooting tactics, etc. While I use this information all the time I thought it is time to give back to the community in hopes that some of my documentation can help others. It will also serve as a place where I can find my documentation when I am looking for it myself.
