Last weekend’s CLE240 saw mediocre propagation for North America and European listeners alike.





It seems that our monthly CLE schedule continues to be synced with the Sun’s monthly rotational period that has been regularly lining us up with the same massive coronal hole, elevating earth-directed solar wind speeds now for several months.

Several CLE participants in the USA commented on the lack of any propagation into BC, further fueling my long-held belief that BC seems particularly sensitive to any geomagnetic activity in the auroral zone to our north. The auroral activity always seems to dip further to the south here for some anomalous reason, as listeners just a few hundred miles to the south or southeast see far less absorption than is observed here.

With a few exceptions, the main effect of these conditions is to largely kill the normal east-west propagation path and just allow single-hop signals from the south or the SE/NW to dominate. Typically, the path to the Pacific is not affected and can often be enhanced.

As a side observation, this past weekend was also the CQWW 160m DX contest and, as one left-coaster commented, conditions were the “worst seen in 10 years”. One would expect to see much better conditions and a much quieter Sun at this point in the solar cycle!

With fingers crossed for better propagation during the next CLE, here is what was logged over the three-night listening event from my location here in BC’s Southern Gulf Islands using a Perseus SDR and an Inverted-L antenna resonated to 400 kHz:

This post builds on the RPi Zero W Cloudlog installation that I did in December with a RPi 3 that was destined to be used in the shack for something. I have long used a laptop to do most of the heavy lifting but have moved most of the clever stuff on to individual machines. The line up is growing but is a bit all over the place. I have….

• A RPi3 as a VHF SatNOGS station that runs nicely but needs a proper home (antenna ia indoors and a lash up)
• A RPi3 as a UHF SatNOGS station that is subject to loads of noise at the moment which needs a cure. It also needs a better home
• A RPi2 as a Flight Radar receiver

A spare RPi3 that was used as a media player in the lounge. Now redundant really as tech has moved on. This needed a new function. So I thought I would bring it into service as a shack server. Trouble is I have no expereince of servers and even the word makes me quiver. I tend to smile, nod politely (It’s a British thing) then retreat carefully to avoid uncomfortable conversation. Anyway it’s time to take the plunge a bit further. I have after all mastered the Cloudlog thing.

What distribution?

Normally I would run straight to Rasbian, but this time I made a detour through to DietPi. It’s a lightweight distribution that supports a few bits of software that are simple to install and configure. Perfect for the lazy, like me. The game is pretty much the same s every Raspberry Pi installation. Find a suitable SD card, burn the image to it and start the machine up. For this the recommendation is to hook up a screen and keyboard for the first bit until it’s all running then you can use SSH or whichever is your preferred method for getting into the machine once it is up and running.

 

What software?

Well Cloudlog for a start. That needed the webserver reinstalling. Guess what? DietPi had one. check the box and that gets installed. Then it was a simple fact of getting Cloudlog reinstalled. Job done and it took a lot less time this go. (need to find a log for this).

Next up was Pi-hole. I’m ok with a bit of advertising, people have got to make a living I suppose but I feel like I’m swimming in a sea of bollocks (figuratively of course, I couldn’t really visualise this literally and don’t want too). Pi-hole claims to reduce the adverts to a more normal level and stops my browser looking like a version of the $1m dollar website (if you can remember that). Something has got to change. Installation was again more simple that you might imagine. Check the box and let the installer do its thing. As I had no idea what I was doing I used the default installation but made the error of not pointing my DNS server to the installation in my router settings. Don’t forget to do that otherwise it won’t do a thing.

There is a nice dashboard that gets filled with clever stuff. Bottom line is that there are already fewer ads on all my devices. Ace!

So what happens now?

Not much really. If you would like to have a go with a really lightweight distro for your raspberry pi (or other sbc – they support all sorts) then give it a go. The easy installation of software make a big difference for dullards like me and avoids time wasting.

I have thought about plugin in a RTL-SDR as a server but don’t really have a need at the moment. Perhaps something for the PiKon telescope now that I have got the lens. We’ll see how the thing goes. One thing I would like is a really simlpe website that does one thing on a button press, but that is a whole new game and perhaps another post.

I’m going to start planning my SOTA activations now
