Accurate time keeping on an Apple Mac running macOS Big Sur for FT8, FT4 and WSPR

ChronyControl

I’ve been using Apple computers for many years now and even though I’ve made a couple of previous blog posts about keeping the clock accurate on a Mac, those methods have never really been needed and I posted them as a sort of belt and braces addition to the built in time-keeping. However with macOS […]

How to automatically link your Pi-Star hotspot to D-Star or YSFReflectors

system cron details

I noticed recently that sometimes my D-Star based MMDVM Pi-Star hotspot would unlink itself overnight from any reflector it was linked to and I decided to investigate and see if I could work out a way to automatically link it to a reflector. If I can’t stop my Pi-Star MMDVM from disconnecting then at least […]

How to update and upgrade your Pi-Star based hotspot

PI-Star SSH logged in

There are a couple of methods of updating a Pi-Star based MMDVM hotspot, one upgrades Pi-Star itself and the other method does a full operating system update as well as Pi-Star. The Pi itself automatically runs a process overnight that updates the host file and various other things but this is how to do a […]

A quick tip for your hotspots

With all the hotspots I have in the house for various modes, I decided to do something about the RF. They all run very low power but they’re only for me to use and I didn’t want the RF escaping the house. I bought a few tiny little dummy loads from eBay and replaced the […]

How to set up a Yaesu System Fusion reflector (YSFReflector)

Over the last four or five years I’ve been a regular user of two digital voice modes, D-STAR and DMR. I don’t particularly like to use them to work ‘DX’ but they both have their advantages regarding linking repeaters together and allowing me to keep in touch with people when I’m away from home. Both […]

Building an MMDVM hotspot on a budget

I bought myself a new handheld at the Newark rally earlier this year, an Anytone AT-D878UV to use on DMR. When I went on holiday in October, I took a couple of copies of RadCom with me and in one of them there was a review of my handheld. The author mentioned that he’d used […]

Installing a radio into my car

About a year ago I changed my car and it’s taken a while to get around to fitting the radio into it. I’ve missed having a wireless in the car and recently resorted to keeping a handheld in the glove box so at least I could natter on the local repeater while driving around town. […]

Receiving weather fax pictures on HF using fldigi

A week or so ago I saw a weather fax (WEFAX) picture someone had posted that they’d captured on HF. This grabbed my attention because I like maps and I like to see things to do with the weather. I’d tried a couple of years ago to receive satellite weather pictures with little success (due […]

Accurate time keeping on an Apple Mac running macOS Mojave

When running data modes such as the very popular FT8, it’s important to keep your computer clock accurate because if it’s more than a couple of seconds out then you won’t be able to decode anyone, they won’t be able to decode you and you won’t make any QSOs.  There are a number of utilities […]
