The Joy Of Building Kits

September 17, 2020 - 11:55 am

I managed to get my hands on a few of the latest (2020) QCX Plus kits from QRP-Labs and as usual I had no difficulty finding homes for the extra kits, obviously keeping one for myself to build in the wee hours of the morning when it is quieter. It was – as always –…

Replacing the BS170 in an Ultimate3S Beacon

March 19, 2018 - 1:48 pm

After the weather zapped the output transistor (a BS150 FET) of my Ultimate3S beacon from QRP-Labs yet again, I was forced to replace the device, again. It is not a difficult job at all, just a little chore. This time I decided to make it easier on myself. Instead of replacing the transistor by soldering…

The QCX – a Nifty Little Gadget

March 5, 2018 - 10:40 am

So yesterday (it was a Sunday) I had a lot to do, but nothing more important than to cut open the wrappings of the 20m QCX kit that I purchased from QRP-Labs a few months ago. Yes, it was still lying in its protective wrappings after all this time. Work is seriously interfering with my…

Beaconing Five Modes in Twenty Minutes

Argo SlowHell callsign

While WSPR’ing across multiple bands (“band hopping”) has been done before, I thought it might be interesting to do five different modes on the same band. It was easier done than said! I was sitting with a customer’s QRP-Labs Ultimate3S beacon on my bench, all built up and ready to test. It was a single…

Measuring the QRPp’s Isn’t Easy

February 9, 2016 - 9:32 am

Interesting how a development in one area of this hobby can force a sudden change of direction to explore some new areas. I’ve been happily experimenting with my Hans Summers Ultimate 3S kit when I realised that I could band-hop and get a picture of propagation conditions updated every 30 minutes or so. Cool idea.…

Ultimate 3 S – part 2 – drifting a bit

January 18, 2016 - 9:16 am

I let the U3s run last night with the first LPF relay board installed (6 bands only) and hopping in sequence from 80m to 10m just to see what can happen. I’m still learning the device, she is not a trivial little kit! I added a CW ID as the last transmission. Anyways to my…

Ultimate 3 S – part 1

January 11, 2016 - 7:52 pm

My latest baby! I will write the full story in a few installments, from the back to the front so to speak, in other words I’ll show you the final result first before going back and showing pictures of the construction and so on. Of course I’m talking about my Hans Summers Ultimate 3S beacon…

WSPRing is addictive

November 5, 2015 - 8:29 am

Like the mermaid calling the sailor, this mode called WSPR seems to be calling me back every time. Circumstances pushed me out of the house into my new outside semi-underground shack which made me QRT for a while while I was painting and renovating, but the first thing I did (after making the few compulsary…

Falklands is a mere WSPR away

June 8, 2015 - 10:55 am

The last thing I did last night was to make peace between my laptop, my Flex-1500 SDR, and the various VAC and VSP drivers and whatever else was struggling to co-exist in the apparently too small memory of my Windows 7 computer. So can you imagine the delightful surprise I got this morning: I switched…

Flex-1500 – Starting the SDR journey

May 31, 2015 - 9:20 am

I might be older, but I’m very young at heart when it comes to technology. I love playing with all the latest gadgets and adopting my hobby to the emerging technologies. One example would be that I only run solid-state amplifiers (watch out for my series of articles on building my own). I also talk…
