Amateur radio digital voice
It’s a mess.
This post is my attempt at a summary of amateur radio digital voice modes, and what I think of them.
I’m not an expert, so if you have more experience then your opinion is likely more valid than mine. But hopefully at least I’m getting the facts right. Please correct me where I’m mistaken.
Analog and digital voice
In the beginning there was only analog. Traditionally on HF you used SSB, and on VHF/UHF you use FM. Analog works, and while yes there are different modes, radios tend to support all of them, or at least the common ones (e.g. most VHF/UHF radios don’t support SSB, because most traffic there is FM). Usually HT traffic is VHF/UHF FM, and for SSB while there is LSB and USB, radios will support both.
But analog isn’t perfect. By going digital we can send metadata such as call signs, positions, and even pictures and files. And for audio quality digital will get rid of the static of analog noise. Digital works better for longer distances, uses less spectrum, and retains voice clarity much longer.
Yes, there’s a sharp cliff when digital voice modes can no longer Continue reading

Terraform an HA-VPN between GCP and Cisco
Doing Infrastucture-as-Code (IaC) with Ansible has given me a headache – so I’ve recently been playing around with Terraform as an alternative to Ansible for certain tasks that require Cloud IaaS interactions. The goal of this blog post is to build an HA-VPN solution between GCP and an on-premises Cisco IOS-XE device (CSR) using Terraform. […]

Trailblazing a Development Environment for Workers
When I arrived at Cloudflare for an internship in the summer of 2018, I was taken on a tour, introduced to my mentor who took me out for coffee (shoutout to Preston), and given a quick whiteboard overview of how Cloudflare works. Each of the interns would work on a small project of their own and they’d try to finish them by the end of the summer. The description of the project I was given on my very first day read something along the lines of “implementing signed exchanges in a Cloudflare Worker to fix the AMP URL attribution problem,” which was a lot to take in at once. I asked so many questions those first couple of weeks. What are signed exchanges? Can I put these stickers on my laptop? What’s a Cloudflare Worker? Is there a limit to how much Topo Chico I can take from the fridge? What’s the AMP URL attribution problem? Where’s the bathroom?
I got the answers to all of those questions (and more!) and eventually landed a full-time job at Cloudflare. Here’s the story of my internship and working on the Workers Developer Experience team at Cloudflare.

Most of us are in some sort of lockdown (or quarantine or shelter-in-place or whatever it’s called) at the moment. Some have their hands full balancing work and homeschooling their kids (hang in there!), others are getting bored and looking for networking-related content (or you wouldn’t be reading this blog).
If you’re in the latter category you might want to browse some of the free ipSpace.net content: almost 3500 blog posts, dozens of articles, over a hundred podcast episodes, over 20 free webinars, and another 30+ webinars with sample videos that you can access with free subscription.
Need more? Standard subscription includes 260 hours of video content and if you go for Expert subscription and select the network automation course as part of the subscription, you’ll get another 60 hours of content plus hands-on exercises, support, access to Slack team… hopefully enough to last you way past the peak of the current pandemic.

Yaesu FT3D vs Kenwood D74
I’ve had a Kenwood TH-D74 for almost two years now, and was curious to get a sense of what the competition is like. Seems like everyone’s recommending the Yaesu FT3D. So I got one, and I think I’ve played around with it enough now to have an informed opinion.
Summarizing the feeling of them, while I have my complaints about the usability of the D74, the FT3D is like a time machine back to the 90s in how well the interface is though through.
I’m sneaking in some mentions of the AnyTone 878UV too. But I’ve not used it enough to have a solid opinion yet.
Programming
With the FT3D upgrading the firmware is a two step process, where you have to flip a little hidden switch first to “up”, to upgrade one firmware, then to “down”, to upgrade the other. And then flip it back to “middle” for normal mode.
The FT3D programming software costs $25 and comes with a special cable, but the software also seems downloadable from their website. The USB cable seems to require a special driver. I guess that’s what you’re paying for. At least you can download the software and put the data on Continue reading
