There is plenty of published information on how to build common mode chokes (CMCs), but not much related to measuring their performance. This post details three such tests using a Nano VNA. If anyone is aware of additional tests which will shed light on a CMC’s performance, I’m all ears.

My FLDigi settings got messed up, and could not identify how to reset it. I tried deleting what configuration data, and uninstalling then reinstalling, all to no avail. Thankfully a video by Stuart (AG6AG), pointed me in the right direction.

Getting voice digital voice keying (DVC) working between N1MM+ and my TS-590SG has been an elusive target, but after another contest without it, I decided it really was a bullet which needed to be bitten. The post will explain the vagaries of the TS-590SG, and why it’s not as straight forward as perhaps some other radios.

Whilst experimenting with a software mixer, I changed the settings within the TS-590SG’s companion application, ARUA-10, which allows software routing of audio between the radio and computer. The titles are somewhat cryptic, so am documenting the default settings here, should they ever need to be reset again.

Renewing LAN based SSL certificates and installing them to a Synology NAS and RouterOS device was a bit of a hullabaloo, so want it documented for when it breaks in three years, by which time I will have forgotten how it was configured.

In trying to consolidate my phone numbers, something broke, and the formatting of my numbers ended up broken. Augh. SQL Server to the rescue!
In keeping with the idea of documenting those obscure (relatively) CLI commands that I only use once in a blue moon and forget if not written down, this one archives the photo’s from the Mac Photos application to our NAS.

By default the AllMon installation with VKNode is not encrypted. What does this mean? If you have your AllMon page publicly accessible, you are sending your admin username and password over the internet in plan text, in the open. That’s bad. Really bad.
This post will detail the steps required to secure your install so that all communication between your node and browser is encrypted.
Using Finder’s copy and paste is a bit daft. There’s nothing nuanced in its operations, or if it is, it’s not user friendly enough for me to have noticed.
All I wanted to do was copy a large number of files to a network drive (around 150 GB worth). This should have been a lot easier than it was.

Running my simplex node on 146.550, I thought it would be nice to see what sort of coverage I achieve with a 1/4 wave ground plane vertical antenna. Just in case Dick Tracy ever asks.
There’s a great tool being hosted by VK2BE at www.ve2dbe.com which lets you generate an RF coverage map easily.
