For the last couple of months, I’ve not done much in the way of traditional radio, largely down to the fact that I’ve been really busy at work. I’ve had lots to do and I’ve spent a month working away from home either on training courses or in meetings preparing for a very large project. […]

A new record – G to ZL on 60m QRSS
Video of the ten minute multi QRPp mode transmission
After my entry a few days ago, I’ve made a video of my Hans Summers Ultimate 3S transmitter going through all four modes in a single ten minute frame. It’s annotated with comments along the way describing what’s happening at every stage.
Running four QRPp modes in a ten minute frame
Over the last month or so I’ve been doing some experimenting using a newly built Hans Summers Ultimate 3S transmitter fitted with the new oven controlled crystal oscillator and I’m now running four different modes in a single ten minute frame with space at the end for a calibration cycle. You should note that to […]
Building a QRP Labs OCXO
20m QRSS warmup
I’ve had this screenshot sitting on my desktop for a while because I think it’s quite interesting. It shows my 20m QRSS signal from when I switched the transmitter on, for a period of nearly four hours. You can see how it takes almost an hour to warm up and calibrate itself to the correct […]
A World First – Experiments on the 60m (5 MHz) band with QRSS
The 60m band is fairly new amateur radio allocation, first introduced in 2002 but only to a few countries such as the United Kingdom, Finland, Denmark, the USA, Ireland, Iceland and Norway. I had an experimental Notice of Variation for 5 MHz on my licence a few years ago and I renewed it when we […]
Running WSPR and QRSS [almost] at the same time
Last month I mentioned that I’d bought a new kit, the “Ultimate 2” transmitter from Hans Summers. I hooked it up with a GPS module and it almost worked perfectly. There were a couple of issues with 2.01 of the firmware and I assisted with beta testing the 2.02 firmware. While testing it, I made […]
Running WSPR (and QRSS) at 200mW
I’ve written a fair bit about WSPR in the past and posted reports of where my signal has been heard using just five watts output. I’ve also written about QRSS including details of the transmitters I’ve built and shown reports of where I’ve been captured. A few weeks ago I heard about a new QRSS kit […]
Days 364 and 365 – Some QRSS and a bit of everything to wrap up QSO365
It feels a little odd to be writing this final regular update for QSO365. It really doesn’t seem like a year ago that it all started and I’m a little relieved to be posting this update, knowing that the project has been a resounding success with not only a QSO made every day of 2011, […]
