Beaconing Five Modes in Twenty Minutes

April 7, 2017 - 9:10 pm
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…

No Sound from my SDR

April 15, 2016 - 8:39 am

And in other news, I’m trying to play with this cute little SDR receiver (the cuteness which I am sharing with you in another post), but I’m having mega problems. Don’t get me wrong: The issue is not SDR or this cute little Rx. I own and operate a Flex-1500 which has quietly become my…

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…

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…

QRSS on 30m with Arduino

January 7, 2015 - 8:43 am

QRSS is not something I knew anything about, until I stumbled across a useful use for my Arduino: A small daughter board (called a shield) with a few components to turn it into a QRSS transmitter. I admit I am lazy and morse code is way out of my reach – know the joke? did…

Working PSK31 with a X1M and Digimaster Pro3

December 29, 2013 - 9:12 pm

Interfacing a Xiegu X1M 5 watt QRP HF transceiver to a G4ZLP Digimaster Pro3 to go digital and portable on the HF bands, by Leon Uys ZR6LU. I recently obtained a Xiego X1M HF radio from OM Rory in Port Elizabeth. Nice package and works SSB out of the box. I took it with me…

Going Digital with G4ZLP DigiMaster Pro3

November 10, 2013 - 1:16 pm

The next critical piece in my quest to become completely QRP-Portable arrived on Friday afternoon. No sooner did I arrive home than I ripped open the box, ignored the instructions, and promptly proceeded to connect and use my new sound card and CAT interface – a DigiMaster Pro3 from G4ZLP. Happiness knows no boundaries! Now…

SignaLink SignaLink Where Art Thou?

October 30, 2013 - 9:59 am

A few days ago I was super-excited when Kobus Conradie ZS1K notified me that my newly purchased SignaLink USB was in the post. I built a few homebrew interfaces and they worked very well, so well in fact that I was ready to consider working mobile and QRP while on holiday. My research indicated the…
